1-1. INTRODUCTION
1-2. The Model 2190A Digital Thermometer is a
portable, stackable, five digit, thermocouple
thermometer capable of temperature measurements over
a range of -252° C to +2471° C (-486° F to +4480* F) with
a resolution of 0.1°. The instrument features automatic
reference-junction compensation, eliminating the
requirement for an ice bath reference-junction; front
panel switch selection of Fahrenheit or Celsius readings;
switch selectable thermocouple inputs; switch selectable
input line voltage; dual-slope measurement techniques;
and digital linearization (microcomputer controlled) of
the thermocouple inputs.
1-3. The instrument display has six high-intensity, seven
segment LEDs, and leading zero suppression. Five of the
LEDs are used to display numeric data, including a minus
sign for negative temperature readings. The remaining
LED displays the selected temperature scale character
(°F or °C). The symbol “0O.C.” is displayed when an open-
thermocouple is detected at the thermocouple input
terminals.
1-4. Screw-type input connectors, on a removable
module, are provided for attaching the selected
thermocouple. The terminals are an integral part of an
isothermal block which serves as a portion of the
reference-junction compensation circuit. This circuit
removes the need for an ice bath reference junction (0°C
or 32°F) since it provides the electrical equivalent
automatically.
1-5. Selection of the temperature scale for display is
made with a front panel pushbutton. The scale selected,
Celsius or Fahrenheit, is displayed as either the character
°C or °F as the last character in the temperature reading.
A scale change can be made at any time, and has no effect
on the calibration of the instrument.
2190A
Section 1
Introduction & Specifications
1-6. The measurement range of the 2190A is determined
by the type of thermocouple used as the input device. The
type of microcomputer installed in your instrument will
determine the type of thermocouples that may be used.
The specifications table identifies the type of
thermocouples that are presently available for use in the
2190A, and Section 2 gives the procedure for identifying
the microcomputer type. The version required must be
specified when ordering the instrument. Choice of the
thermocouple type is accomplished by selecting the
applicable switch position on the removable input
module using the table printed beside the switch on the
pcb. Recalibration is not required if the thermocouple
type is changed.
NOTE
The letter C is not an ISA/ANSI
thermocouple desgnation. C is used for
convenience only to represent Tungsten-5%
Rhenium versus Tungsten-269 Rhenium
alloy.
1-7. The instrument is in a PTI (Portable Test
Instrument) case. This lightweight, durable plastic case
makes the instrument truly portable when used with the
Y2003 or Y2009 external power sources and can be
stacked for one handle portability.
1-8. Options and accessories available for the 2190A are
listed in Tables 1-1 and 1-2 respectively. Detailed
information concerning each item listed is given in
Section 6 of this manual, Option and Accessory
Information.

1-9. Four input line voltages are available for switch
selection. Selection may be made for 100, 120, 220 or 240
volts +10%, as required to meet local conditions.
Frequency may vary between 50 to 440 Hertz for all
voltage selections. Refer to Section 4 of this manual on
how to change the selected input line voltage. The
instrument will also operate with an external input of 12V
dc.

Operating Instructions
2-8. The rear panel ac input connector is a three-prong,
U-ground connector which permits the instrument to be
connected, via the power cord, to the applicable line
voltage. The offset prong on this connector is connected
to the 2190A transformer shield and should be connected
through the power cord to a high quality earth ground.
The rear panel external 12V dc connector accepts two
wires from an external supply. The two receptacles are
marked for polarity.
2-9. INSTALLATION
2-10. The 2190A and its individually packaged
accessories are installed in PTI (Portable Test
Instrument) cases. These cases are stackable, allowing the
operator to fasten them together and transport a series of
instruments as one unit. The maximum weight for the
stacked units is forty pounds.
2-11. Prepare the 2190A for operation by plugging the
input line power cord into the applicable power source or
connecting the external input connector to an external
12V dc source.
2-11a. When interfacing your 2190A with a Fluke 2300A
Scanner, use the following procedure to readjust the zero
calibration of the 2190A:
1. Turn the 2190A and 2300A power off.
2. Remove the Thermocouple Input Assembly from
the rear of the 2190A and ensure that the input termi-
nals are open.
3. Place the eight position (labeled on the PCB) of
S1 on and replace the Thermocouple Input Assembly
into the 2190A.
4. Remove the Thermocouple Scanner Card
(Option -002) from the 2300A Scanner, short the
2-1
2190A
input terminals for one of the channels and replace
the Thermocouple Scanner Card into the 2300A.
5. Plug the 2300A Interface Option Cable into the
2190A Accessory Connector on the rear of th
2190A. |
6. Turn the 2190A and 2300A power оп.
7. Set the 2300A to the channel that was shorted in
step 4.
8. Set the 2300A channel delay to 0.0.
9. Adjust the 2190A zero potentiometer (located on
the 2190A front panel, behind the screw-locked
cover) to obtain a 2190A display of 0.0.
2-13.
10. Turn the 2190A and 2300A power off, remove
the Thermocouple Input Assembly from the 2190A,
move all switches of S1 to the off position and replace
the Thermocouple Input Assembly into the 2190A.
NOTE
The 2190A zero will need to be readjusted if not
being used with the 2300A. To readjust the
2190A zero, turn the 2190A power off, remove
the Thermocouple Input Assembly, short the
input terminals, repeat step 3, turn the 2190A
power on, and repeat step 9.

2-15. The following paragraphs describe various
conditions that could effect operation of the
thermometer. The operator should familiarize himself
with these conditions prior to operating the 2190A.
2-16. Option Information
2-17. Supplementary operating instructions are
necessary when operating a 2190A equipped with one of
the available options. Detailed information regarding the
operation of each available option is given in Section 6 of
this manual, Option and Accessory Information.
2-18. Fuse Replacement
2-19. The ac line input and external dc input are
individually fuse protected. Both fuses are readily
accessible on the outside of the rear panel. The ac line
input fuse (F1) should be replaced with a 1/8A slo-blo
fuse if either 100 or 120 volts has been selected as the input
line voltage. Use a 1/16A replacement if 220 or 240 volts
have been selected. The external dc input (F2) requires a
3/4A slo-blo fuse for a replacement.
2-20. Overload Thermocouple Indication
2-21. The front panel display, in addition to providing a
measurement reading, provides an indication of an
overload on the input thermocouple. When the
measurement range of the selected thermocouple is
exceeded the display flashes either the full-scale positive
or full-scale negative reading, dependent on the polarity
of the overload. The blinking indication does not
necessarily indicate that the instrument is exposed to a
damaging input condition.
2-22. Open Thermocouple Indication
2-23. If the thermocouple is open, or not connected to
the input terminals, the display flashes the characters
”0.C.”. A signal from the rear panel relay contacts can
also be obtained if the Limits Option (-006) is installed.
To accomplish this, select either the positive (+OL) or
negative (-OL) position on S4, located on the Main PCB
(refer to Section 4 for access to the Main PCB), depending
upon whether the Limits Option is set to greater than (>),
or less than or equal (<5). If the limits are set for >, the S4
switch should be set to +OL for an open thermocoupleto
close the relay contacts for a signal. Conversely, for a
signal with a < limit, -OL should be selected.

3-1. INTRODUCTION
3-2. This section of the manual contains an overall
functional description, followed by a brief circuit analysis
of the 2190A Digital Thermometer. Simplified circuit
diagrams are provided, as necessary, to supplement the
text. Detailed schematics are given in Section 8 of this
manual.
3-3. OVERALL FUNCTIONAL DESCRIPTION
34. The Model 2190A Digital Thermometer, shown in
Figure 3-1. is a 5-digit microcomputer controlled
thermocouple thermometer capable of resolving 0.1°C or
0.1°F over temperature range of -252° to 2471°C or
-486° to 4480°F. It features a reference-junction
compensator (eliminating the need for an ice bath
reference-junction), dual-slope A/D conversion
technique. microcomputer control logic, and a S-digit
display with temperature scale indicator.
3-5. In operation, the 2190A executes a continuous
series of measurement cycles to update the temperature
displav. The measurement cycle is controlled entirely by
the microcomputer and includes three major subcycles:
the Auto-Zero, Integrate, and Read periods. Each
subcycle controls the operation of the analog section of a
dual-slope integrator, which in turn. generates a compare
output. which 1s used by the microcomputer to generate
the proper control signals. (In addition to these major
subcycles. a recovery signal is applied at the end of the
read period to assist the Auto-Zero period.)
3-6. The configuration of the analog section duringeach
phase of the measurement cycle. is established by the
condition of microcomputer controlled FET switches.
The measurement cvcle begins with the Auto-Zero
period. During this period, the input to the Buffer
Amplifier 1s connected to ground through an FET switch
and the accumulated dc offset voltages present in the
analog section are sampled and held by the Auto-Zero
2190A

Theory of Operation
capacitor. This voltage is used later in the measurement
cycle to cancel measurement errors introduced by offset
voltages present in the analog circuitry. As a result, the
final measurement is proportional to the thermocouple
probe output voltage and does not include offset errors.
3-7. During the Integrate period, the thermocouple
input voltages (probe voltage and input terminal
voltages) are applied to the integrator and the algebraic
sum of these voltages 1s integrated over a 100 ms period.
At the end of this period the thermocouple input voltages
are removed from the integrator and the Read period is
started.

3-8. A reference voltage 1$ applied to the integrator
during the Read period, causing the integrator capacitor
to be discharged at a linear rate. When the integrator
output reaches the voltage stored on the Auto-Zero
capacitor a compare signal is generated to end the Read
period. The duration of the Read period is translated by
the microcomputer to provide a digital indication
proportional to the thermocouple probe voltage.
3-9. To compensate for the error voltage present on the
input terminals, the microcomputer configures the analog
portion to do a complete conversion cycle on the
reference-junction voltage every llth read cycle. This
voltage is generated by a transistor which is at the same
temperature as the input terminals. The microcomputer
uses the number generated during the Read period to
compensate the input voltage and display the actual
probe temperature.
3-10. CIRCUIT ANALYSIS
3-11. Circuit analysis of the 2190A is discussed in two
sections; digital and analog. The digital section is covered
first and particular attention is paid to the control it
exercises on the analog section. The analysis of the analog
section covers the analog measurement circuitry and the
power supply.
3-12. Digital Section
3-13. The digital section of the 2190A consists of a
single-chip microcomputer (U4), which has a self-
contained, programmed, read only memory; a hex
CMOS open drain buffer (U3) and an LED display. Its
function is to convert the non-linear thermocouple probe
voltage, as measured by the analog section, into a linear
digital display, provide the necessary control signals to
the analog section and to provide control for all
accessories on an accessory bus. The 2190A LED display
provides a direct reading of the probe temperature in *C
or °F.
3-14. The microcomputer contains all 2190A program,
control logic, and linearizing capability and provides the
display with all signals necessary to update the display.
The linearization of the non-linear input signal is
accomplished by selecting one-of-several programs which
compute the correct temperature using a 4th-order,
curve-fit approximation of the probe output. The
operating program is selected to match a particular
thermocouple type and is enabled by the numeric setting
corresponding to the thermocouple type in use. The
rotary switch is located on the thermocouple input
assembly next to a table showing the switch setting
applicable to the thermocouple type in use.
3-15. Measurement data 1s continuously strobed out of
the microcomputer in decoded-seven-segment, character-
3-2
serial format and sent to the LED display. With an
overload condition the display flashes on and off. An
"O.C.” display indicates an open thermocouple probe
condition.
3-16. The basic measurement cycle shown in Figure 3-2,
consists of three major subcvcles; a 100 ms minimum
Auto-Zero period, a 100 ms integrate period, and a
variable Read period. The total measurement cycle time
consists of 300 ms; 100 ms to integrate, up to 100 ms to the
Read period, and the remaining time to the Auto-Zero
period. (Auto-Zero time wiil vary from 100 to 200 ms.) To
accomodate settling times in the analog section a (4) 2,
(1 ms nominal) hold signal is inserted at the beginning and
at the end of the Integrate period.
3-17. Analog Section
3-18. ANALOG MEASUREMENT CIRCUIT
3-19. The analog circuit is shown in simplified form in
Figure 3-3. It consists of a thermocouple input circuit, a
reference-junction compensator, a voltage reference, a
buffer amplifier, an integrator, a gain stage, a
comparator, and a combination of FET switches. The
switches are shown in their open state and are closed by
the measurement cycle commands generated by the
microcomputer.
3-20. The Thermocouple Input circuit consists of an R-
C filter and a pair of voltage protection diodes. The
difference between the thermocouple probe voltage and
the input terminal voltage 1s passed through the filter and
appears at FET switch Q15. The R-C filter increases the
normal mode rejection capability of the 2190A.
3-21. The reference-junction compensator consists of
an isothermal block, a pair of screw type input terminals
and a transistor temperature sensor, (all on the
Thermocouple Input Assembly). The isothermal block
maintains a negligible temperature differential between
the input terminals and the temperature sensing
transistor. Thermocouple voltages introduced by the
dissimilar metals at the input terminals vary as the
isothermal block adjusts to ambient temperature.
Temperature changes are sensed by the forward biased
transistor to produce a correction voltage which is read by
the analog measurement circuitry every eleven cycles. The
reading is saved by the microcomputer and is used to
compensate for the error voltages present at the input
terminals. Predictable characteristics of a forward-biased
P-N junction allow the reference-junction compensator
to function over a wide temperature range. This
correction voltage occurs at FET switch Q17.
3-22. The voltage reterence consists of a thin-film
resistor network supplied bv an accurate 6.2V dc
reference voltage. The divider is set to provide 100 mV
and 200 mV. These voltages appear at FET switches Q12
and Q13, respectively.

Figure 3-2. Measurement Cycle Waveforms
3-23. The Buffer, Integrator, Gain Stage, and
Comparator Amplifiers combine to perform the analog
functions of the Integrate, Read, and Auto-Zero periods.
The Buffer is used to provide integrator inputs during all
three periods. The Integrator integrates the Buffer output
voltage during the Integrate and Read periods and, in
combination with the Gain Stage, functions as a closed-
loop amplifier during the Auto-Zero period.
3-24. During the first phase of each measurement cycle,
the analog section goes through an Auto-Zero period.
During this time, four auto-zero switches (Q12, Q16, Q6,
and Q10) are closed by the Auto-Zero command from the
microcomputer. Two of the switches (Q12 and Q16)
charge the reference capacitor to 100 mV. Switch Q16
also zeroes the input to the buffer amplifier. The third
switch, Q6 connects the Integrator and Gain Stage into a
closed-loop configuration and allows the auto-zero
capacitor (C10) to charge to a value which is proportional
to the algebraic sum of all the offset voltages present in the
Buffer, Integrator, and Gain Stage. At the end of the
Auto-Zero period, switches Ql2, Q16, Q6 and Q1l0 are
opened. The VREF capacitor and the auto-zero capacitor
retain their charge for use later in the measurement cycle.
3-25. The Integrate period (see Figure 3-2) starts on the
leading edge of the integrate command from the
microcomputer; switch О15 is closed and switch Q8 is
opened. The thermocouple input voltage is applied
through switch Q15 to the buffer input. After a | ms
settling period, switch Q8 closes and the buffer output is
applied to the Integrator for 100 ms. As the integrator
capacitor charges, the Integrator drives the comparator
(through the Gain Stage) to either 0 or +5V dc to indicate
the polarity of the thermocouple input voltage, negative
or positive, respectively. At the end of the Integrate
period, the integrate capacitor is charged to a level and
polarity which are proportional to the thermocouple
input voltage and switches Q15 and Q8 return to the open
state.
3-26. The Read period starts at the end of the Integrate
period and one-of-two Read modes is enabled depending
upon the input polarity sensed by the comparator during
the Integrate period. If a positive input is sensed, a
positive Read mode is enabled. Similarly, a negative Read
mode is enabled when a negative input is sensed.

3-27. If the positive Read mode is commanded, FET
switch Q11 ıs closed. This grounds the positive end of the
VREF capacitor which effectively applies -100 mV to the
input of the buffer.
3-28. If the negative Read mode 1s commanded, switch
Q13 is closed connecting the positive end of the VREF
capacitor to +200 mV. Therefore, the voltage applied to
the buffer is the algebraic sum of 200 mV and the voltage
across the reference capacitor. This effectively applies
+100 mV to the input of the buffer.
3-29. After a | mssettling time, switch Q8 closes and the
buffer output voltage is applied to the integrator input,
causing the integrator capacitor to discharge at a linear
rate determined by the reference voltage. The discharge
continues until the integrator voltage reaches the
comparator trip point, which is referenced to the voltage
on the auto-zero capacitor. When this level is reached the
comparator changes state, commanding the
microcomputer to terminate the Read period. To
facilitate Auto-Zero, the microcomputer then calls a
reference voltage opposite in polarity to the one
previously used. When the integrator again reaches the
trip point, the microcomputer immediately begins the
Auto-Zero period.
3-30. Offset voltages present during the Integrate and
Read periods are cancelled by offset voltages that were
sampled and held during the Auto-Zero period. However,
during conversion within the microcomputer, the
temperature corresponding to the reference-junction
2190A
voltage is added to the measurement data and, as a result,
the displayed temperature 1s equal to the thermocouple
probe temperature.
3-31. O.C. DETECTOR
3-32. The open thermocouple detector (Ul4 and its
associated circuitry) on the thermometer is used to
determine whether or not the impedance at the input
terminals exceeds a predetermined level. It therefore
provides an indication of a broken or faulty
thermocouple. A square wave 1$ applied to the input of
the thermometer and its magnitude is compared to a
reference square wave. If the reference is exceeded, an
open circuit condition is detected. This occurs at a

3-33. POWER SUPPLY
3-34. The 2190A power supply consists of a DC-to-DC
Converter and voltage regulating circuitry. AC inputs are
made via the input power cord, line fuse, and power
transformer/ rectifier. External +12 volt dc inputs can
also be made directly to the DC-to-DC Converter via line
TBI (see Main PCB schematic, Section 8). The function
of the power supply is to provide +5, +15, and -15 dc
operation voltages for the 2190A circuitry. The power
supply can be driven from AC line or 12V dc external

600-3. MULTIPOINT SELECTOR, (Y2001)
600-4. The multipoint selector allows the operator to
manually select and monitor one of up to ten channels.
Two separate thermocouple types (maximum of five each
if two types used) may be connected to the unit. Up to ten
multipoint selectors may be connected in series.
600-5. CALIBRATOR, THERMOCOUPLE
INDICATOR (Y2003)
600-6. This accessory, when used in conjunction with
the 2190A, provides a variable output for calibration of
less sensitive thermocouple devices than the 2190A. The
2190A display 1s controlled by the calibrator millivolt
output (-10 to +90 mV dc) and the less sensitive
thermometer may be adjusted to the 2190A displayed
temperature. The Y 2003 can perform remote calibrations
using its self-contained battery pack as a source and can
supply external power to the thermometer from this
battery pack.
600-7. BATTERY PACK, 12V
RECHARGEABLE (Y2009)
600-8. The rechargeable battery pack provides the
2190A and its accessories with portability. The output is
+12V dc at a maximum of 750 mA for a total of 2.2
ampere-hours.
2190A
Accessories
600-9. DIVIDER, THERMOMETER
CALIBRATION (Y2022)
600-10. The device is a preset 100to | divider to provide
the precision millivolt outputs from a DC Calibrator
required for calibration. The device wires into the
Thermocouple Input PCB in place of the thermocouple
probe during calibration. Refer to the Y2022 Instruction
Manual for the schematic and additional information.
600-11. RACK PANELS
600-12. Available are rack mounting panels in three
sizes and two types for the standard 19-inch electronics
equipment racks. The “A” size for the multipoint selector
is available in panels that will accomodate either one or
two instruments. The "B” size panel for the calibrator
and/or battery pack is also available for single or double
instruments, as is the ”C” size used for the 2190A
Thermometer and the Alarms Output.
600-13. PANEL MOUNTS
600-14. The panel mounts provide the hardware to
install the instrument in any panel in which a hole the size
of the instrument front panel can be cut. It is available for
the three instrument sizes required, ”A”, ”B”, and ”C”.
600-15. THERMOCOUPLE PROBES
600-16. Thermocouple probes are available from the
John Fluke Mfg. Co., Inc. as determined by
microcomputer type, see Table 1-3, Specifications.
600-17. POWER CORD, 3-WAY (Y2024)
600-18. This accessory is a specially constructed power
cord with three female and one male connectors that
allow the operator to connect up to "C” size or smaller
PTI instruments with one line power cord.
600-1
2190A
600-19. CABLE OUTPUT UNIT,
RS-232-C (Y2026B)
600-20. The Y2026B is an interface device which allows
direct mating between any RS232C device and the -002
Output Option. The Y 2026B consists of two 25-pin connec-
tors, one 36-pin connector, and an accessory cable to con-
nection between the 36-pin output and the -002 Output
Option. It will be necessary for the user to provide the cable
between the 25-pin outputs and the RS232C devices.
600-2
600-21. THERMOCOUPLE INPUT
MODULE (Y2030)
600-22. The Y2030 is the thermocouple input module
compatible with the 2190A Digital Thermometer only.
Basically the Y2030 compensates for errors introduced by
ambient temperature variations and allows the user to
select the proper microcomputer program for the
thermocouple type in use. For additional information
and the schematic, please refer to the Model Y2030
Instruction Manual.
602-1. INTRODUCTION
602-2. The 21X0-002 Option 1s an analog and digital
output unit. It provides either the 2180A or 2190A Model
Digital Thermometers with a recording output for a
permanent record when required. The option may be
ordered with the unit for factory installation or 1s
available as a kit for installation in the field.
602-3. The analog output is available on the rear panel
at two flush banana jacks with the polarity indicated. The
output is a scaled voltage source of | millivolt per degree
of temperature, regardless of the temperature scale
selected, with the polarity as read on the display. For
example; a reading of 251°F would output +251 mV dc;
97.3°C would output +97.3 mV dc; and -31.9°F would
output -31.9 mV dc.
602-4. The digital output is a clocked message that can
be in two different formats to match the requirement of
the customer's equipment. Output on one set of lines is a
bit-parallel, byte-serial message format designed for
printer interface. Also available are the standard EIA
RS232C and current loop bit-serial outputs. Both
formats provide the channel number, the current reading
displayed, and any out of range or open thermocouple
information.
602-5. SPECIFICATIONS
602-6. Specifications for the Output Option, 21X0-002,
are as listed in Table 602-1.
602-7. INSTALLATION
602-8. Options for field installation can be installed

602-9. OUTPUT CONNECTIONS
602-10. All connections between the Output Unit
Option and external instruments are made using the rear
panel connectors previously described. The analog
output is from standard banana jacks. The digital output
female connector has a mating male connector
accompanying the option. This allows the customer to
custom make a cable between the thermometer output
option and the receiving device. Table 602-3, is the pin-
out data for the digital output connector.

NOTE
Standard RS232C signals are output on 25-

602-11. OPERATION
NOTE
For RS232C or 20 mA current loop operation,
the -002 address switches may be ignored.
The Data Set Ready (DSR, pin 33) or Clear
To Send (CTS, pin 32) must be at +3V t10+15VY
in order to output data on the RS232C bus.
These lines can be tied to Request To Send
(RTS), pin 31) which provides the required
+157.
602-12. Once the Output Unit Option is installed, the
only operator functions deal with the connection of
external equipment to the analog or digital output
connectors.
602-13. The positive and negative analog terminals have
available a dc millivolt output with the same polarity, and
proportional to the temperature displayed. For example,
if the thermometer displayed +105.7° F the analog output
would be +105.7 mV dc and for -53.1°C the output
would be -53.1 mV dc. The full resolution of the
temperature display (tenths or hundredths of degrees) is
reflected on the output.
602-14. The digital output can be connected to a printer
or any device accepting parallel ASCII data, or to a device
accepting RS232C or Current Loop signals. Connections
for all three types of signals are available simultaneously
on the 36-pin output connector previously described.
602-15. THEORY OF OPERATION
602-16. The Output Unit Option converts the
temperature displayed by the output into a format usable
by the customer's equipment. The output may be
available as a scaled analog voltage or as formatted
parallel and serial ASCII digital output. The following
paragraphs describe operation of the Accessory Bus that
handles communication between the instrument and the
options, the analog output circuitry and the digital output
circuitry. Refer to the schematic in Section 8 during the
following discussion.
602-17. Accessory Bus Communication
602-18. The option communicates with the
thermometer on the clocked bit-serial accessory bus.
Transmitted on the bus are channel number, range,
conversion type, scale, and digits of the temperature
reading. When the WRTADR line is held low, DCLK
clocks the address of the Output Unit (4), followed by the
thermometer data to the microprocessor on the DATA
21X0A-002
line. Once into the microprocessor, the data is converted,
formatted, and output to the analog and digital output
circuitry.
602-19. Analog Circuitry
602-20. The temperature reading received by the
microcomputer 1s used to generate an integrate control
signal, the length of which is proportional to the
magnitude of the temperature reading. This signal is used
to turn on (close) the FET switches Q6 and Ul2-2, open
the switches Ul1-2, Ul1-3 and U12-3, and set the output
polarity with switches at Ul2-9 and Ul2-10. (U12-9 1s
closed when a negative reading 1s being processed and
Ul2-10 when a positive signal is being processed.)
602-21. With Q6 on, the capacitor Cl is charged linearly
to a voltage proportional to the length of the control
signal at Q6. When Q6 has been on for the time required,
it is opened, and switch Ul 1-13 is closed, so the output of
U13-8 can be sampled and held on C2. After 10 ms switch
U11-3 opens and switch Ull-11 closes to zero the
integrate capacitor C1, until the next conversion cycle.
602-22. The voltage held on C2 is buffered by U13-7.
Ul3-14 either passes the voltage directly to the output
stage, or amplifies 1t as controlled by switches U12-9 and
Ul2-10, which alternate states to set the polarity. The
output stage at Ul3-1 has a constant gain of -l.
602-23. Digital Output Circuitry
602-24. The thermometer reading transmitted on the
accessory bus every 333 ms is formatted by the
microcomputer and, if requested, made available on the
PTI Bus, RS232C, and current loop outputs. Refer to the
schematics in Section 8 during the following description.
602-25. Eight data, four address, a data valid, an address
valid, and an acknowledge line are used by the PTI Bus
Interface. The external device requests data from the Out-
put Unit by applying the preselected address to the address
lines. The address is preselected by setting switch S3 to the
desired number (0-9). When the proper address is decoded
the tri-state output buffers (U8 and U9) are enabled, and
the microcomputer and external device are notified that the
Output Unit has a valid address. When the conversion pro-
cess is complete, the microcomputer applies the first char-
acter of the formatted data to the output lines and pulls the
DATVAL line low. The external device reads the data and
pulls the ACK line low, causing the Output Unit to reply
With a new character. The process 1s repeated until data
transfer is complete. The message formats are shown in
Figure 602-1, and a timing diagram is shown in Figure
602-2.
602-3
21X0A-002
602-26. After transfer to the printer lines is complete,
the microcomputer checks the DATA SET READY and
CLEAR TO SEND lines from the RS232C Interface. If
both lines are high, the same message as was output on the
print lines is output on the RS232C and current loop lines
in a bit-serial format. Since the thermometer cycle rate of
333 ms is shorter than the time required to output data at
BAUD rate of 1200 and less. a message is not transmitted
during every instrument cycle.
602-27. CALIBRATION
602-28. Analog circuitry in the option should be
calibrated every 90 days or after any repair of the unit.
The procedure following assumes that power is supplied
to the unit and that a Digital Voltmeter capable of reading
10 uV on the | volt, or equivalent range, 1.e., a Fluke
Model 8800A, 15 available.

604-1. INTRODUCTION
604-2. Option 21X0A-004 IEEE-488 Interface provides
the 2180A and 2190A digital thermometers with a direct
output only connection to the IEEE-488 bus.
604-3. Option 21 X0A-004 may be ordered with the 2180A
and 2190A thermometers for factory installation, or is
avallable by itself for service center installation. Option
21 X0A-004 cannot be used in a 2300A Scanner system. For
more compatibility information, refer to “Compatibility
With 2300A and Previously Produced Thermometers”.
604-4. The IEEE-488 standard connector is accessible
from the rear panel of the thermometer. The format of the
output data includes the channel number, the current read-
ing, and any out-of-range or open thermocouple informa-
tion. (Refer to Table 604-3.)
604-5. SPECIFICATIONS
604-6. Specifications for Option 21 X0A-004 are shown in
Table 604-1.
NOTE
The L4 listener function indicates that the
thermometer TEEE-488 bus interface has the
same 5-digit talk and listen addresses, and that
the receipt of a listen address disables the talk
address.
604-7. |EEE-488 BUS ADDRESS CODE
SELECTION
604-8. A six-position dip switch (SW3), located on
Option 21 X0A-004 pca (printed circuit assembly), sets the
IEEE-488 bus address codes for the option. To gain access
to SW3, lift off the case top of the thermometer by remov-
21X0A-004
Option -004
IEEE-488 Interface
ing the six screws from the base. Referring to Table 604-2,
set positions | through 5 of SW3 to assign the desired
address.
604-9. OPERATION
604-10. Once Option 21 X0A-004 is installed and SW3 is
properly set, make sure that the IEEE-488 cable is correctly
connected to the option to ensure that all functions are
properly monitored by the controller.
604-11. Program Considerations
604-12. Position 6 on SW3 controls the SRQ signal (Ser-
vice Request) to the IEEE-488 bus. Upon receiving an
SRQ, the controller serially polls each device on the bus for
SRQ status. SRQ status of the Option 21 X0A-004 is indi-
cated by bit DB6 (position 64 decimal, 40 hexadecimal) in
the serial poll register (U12). With SW3 position 6 in the
ON position, SRQ is generated when a LF (line feed) 1s
received in the 32-byte buffer of Option 21 X0A-004. The
LF character is used by the thermometer to indicate the end
of a data transfer to the Option 21 X0A-004. (Refer to Table
604-3.) Option 21 X0A-004 sets DBI (2 decimal), which
causes a serial poll to return a total value of decimal 66 or 42
hexadecimal,
604-13. When the SRQ mode is enabled, the SRQ is set
when the thermometer makes a reading available to the
Option 21 X0A-004. The reading is held indefinitely until
the SRQ is serviced. All new readings from the thermom-
eter are discarded. When SRQ is disabled, the output
buffer is continuously updated with the most recent reading
from the thermometer. However, there may be a 0.33
second delay encountered in the returned reading. This
delay occurs when one reading 1s sent across the IEEE bus
and the Option 21X0A-004 waits for the thermometer to
send the next reading. An IEEE bus timeout error may
occur unless the timeout is set longer than this delay.

604-14. Message Format
604-15. Table 604-3. contains the sequence of information
in the output data string. The sequence is the fixed length
format presented on the IEEE bus.
604-16. Sample Programs
604-17. The following sample programs show two differ-
ent situations in which the controller receives temperature
readings from the thermometer. The program listed in Fig-
ure 604-1 instructs the controller to asynchronously retrieve
a temperature reading after an SRQ has been sent from the
thermometer. The program listed in Figure 604-2 instructs
the controller to ask for a temperature reading at a specific
program step.
604-18. SRQ Program
604-19. The SRQ program, when typed into a 1720A,
1722A, or 1752A controller informs the controller what to
do when an SRQ is received from the thermometer. The
program allows the controller to perform other tasks until
the thermometer has a temperature reading. The thermom-
eter sends a 66 hexadecimal value back to the controller in
response to the serial poll (SPL). If more than one ther-
mometer or more than one other instrument (a maximum
of 14) is connected to the controller, the program distin-
guishes which instrument is sending the SRQ and deter-
604-2
mines priority if more than one SRQ is received at the same
time. After the controller receives the temperature reading
and prints it on the controller screen, the program ends the
SRQ handling procedure and waits for another SRQ.
NOTE
The following programs are written in Fluke
BASIC and operate on the 1720 A, 1722 A, and
1752A controllers. A modification of the SRQ
program may be required to conform to other
IEEE controllers.
604-20. The Non-SRQ Program
604-21. The sample program in Figure 604-2 inputs and
prints temperature readings without the use of an SRQ. A
2-second delay is required after the TRIG @2 statement
(line 50) to allow Option 21 X0A-004 to finish the reset pro-
cess before requesting readings from it. The TIMEOUT
delay (line 70) must be set greater than 333 ms, so the con-
troller waits for the thermometer to provide the next read-
ing to the INPUT statement.
604-22. Group Execute Trigger
604-23. The Option 21 X0A-004 responds to the IEEF-
488 GET command by simply resetting the two micropro-
cessors (U5 and Ul1) on the board. Resetting the microp-

the IFFF-488 interface chip (U12), and 1s a recommended
start-up procedure at the beginning of the program in the
[EEE-488 controller. A 2 second time delay is required to
complete the resetting operation. Do not attempt to access
Option 21 X0A-004 before the end of the time delay.
604-24. Functional Equivalent
604-25. The operation of Option 21 X0A-004 is functionally
equivalent to the combination of the Fluke 21 X0A-002,
2X XX A-522, and 1120A with the exception of the follow-
ing four items:
CHANGES:
|. Option 21X0A-004 displays a lower case (d)
instead of a blank in front of the temperature
scale indicator. See Output Format, Table 604-3.
2. Option 21 X0A-004 operates at the full speed rate
of the thermometer, (3 readings per second,
instead of 1.5 readings per second).
3. The 2XXXA-522 previously contained a buffer-
full SRQ function that produced an SRQ when
the 32-byte buffer is filled. The buffer-full SRQ
function no longer exists with the 2XXXA-522,
but the switch is still present and its function is
still listed in the 2XXXA-522 manual. The
buffer-full SRQ function is not available on
Option 21 X0A-004.
ADDED
FEATURE:
4. Option 21 X0A-004 responds to a Group Execute
Trigger. See Group Execute Trigger, paragraph
604-23.
604-26. If you include Option 21X0A-004 when up-
grading or adding new equipment to a system currently
operating with the 21X0A-002, 2XXXA-522, or [120A
combination, note the first two changes listed in paragraph
604-25.
604-27. THEORY OF OPERATION
604-28. Option 21 X0A-004 converts the temperature dis-
played by the thermometer into a format usable by an
[EEF-488 Bus Controller. Option 21X0A-004 communi-
cates with the thermometer on the clocked bit-serial acces-
sory bus. The channel number, range, conversion type,
scale, and digits of the temperature reading are transmitted
on the bus. The cycle is repeated every 333 ms. When the
Write Address (WRTADR-) line is held low, Data Clock
21X0A-004
(DCLK-) clocks the accessory bus address then the ther-
mometer data into the 3870 microprocessor (US) on the
DATA- line. In US, the data is formatted (Table 604-2) and
made available for transfer to the 8748 microprocessor
(UI).
604-29. US applies a character to the tri-state buffers (U8
and U9) and pulls the Data Valid (DATVAL) line low. If
UII is not transferring data to U12 or if it is waiting for
SRQ to be serviced, Ull responds to US by strobing the
character onto the Option Data Bus with a STROBE- sig-
nal and reads the character into its 32-byte buffer. Ull also
generates Acknowledge (ACK), which causes U5 to reply
with a new character. When an LF character is detected,
Ul unmasks the byte-out interrupt. If the SRQ switch is
set to ON, the SRQ switch triggers the GPIA (General
Purpose Interface Adapter) to send SRQ to the controller.
The 32-byte buffer never completely fills because ther-
mometer readings consist of 21 bytes.
604-30. The IEEE-488 Bus Controller initiates the talk
mode by sending the talk address to the GPIA (U12) over
the IEEE-488 bus when Attention (ATN) is asserted true
low. The GPIA responds by setting the byte-out interrupt
(U 12-40) high, as a signal to Ul! to pass data bytes to U2.
The following three conditions must be met before data
transfer can begin:
e Ready For Data (RFD) from the IEEE-488 bus
is true (low).
e Data Accepted (DAC) from the I EEE-488 bus is
false (high).
e Ull must have the byte-out interrupt unmasked.
604-31. When the above conditions are met, Ull sends
the data byte to the Data Out Register of the GPIA via the
Option Data Bus. At this time, the byte-out interrupt is set
to zero, and the data byte is checked for the LF character.
The GPIA handshakes the data byte to the IEEE-488 Bus,
and the byte-out interrupt (U 12-40), transmitted to Ul, 1s
set to |. If the data byte is an LF character, EOI (End or
Identify) is also sent to the IEEE Controller to signal the
end of a data reading. This process continues as long as
there is data in the 32-byte buffer of Ul1. When the 32-byte
buffer is empty, Ull masks the byte-out interrupt from the
GPIA.
604-32. The IEEE-488 address setting for Option 21 X0A-
004 is read by the GPIA (U12) via the Option 21 X0A-004
data bus when the GPIA sends a strobe out on U12-4 to the
address switch tri-state buffers (U I8).
604-33. Whenthe GPIA detects a Group Execute Trigger
for its address, it sets U12-24 to a logic high to cause a
604-5
21X0A-004
Power On Reset (POR) via Q4 and U6. The POR resets
US and UlI, and lasts for approximately 150 ms.
604-34. The power supply for Option 21 X0A-004 power
supply is a standard linear regulator using a full-wave
center tap rectifier and pass transistor regulator (Q5). The
regulator is driven by U17 and Q6, and is referenced from a
2.5-volt band gap reference (U 15). U16 performs POR and
low voltage detection. The option provides its own power
rather than using the power supply of the thermometer,
which is unable to provide enough additional power.
604-35. Option 21 X0A-004 is a consolidation of the cir-
cuitry from Option 21 X0A-002, Option 2XXXA-522, and
1120A that is required for IEEE-488 output operation. The
consolidated circuitry does not include analog output cap-
ability or the slow serial communication link between the
Option 21X0A-002 and 2XXXA-522 microprocessors.
Instead, the circuitry uses the PTI (Portable Test Instru-
ment) parallel output port of the Option 21 X0A-002 to
communicate with the Option 2XXXA-522 microprocessor.
604-36. COMPATIBILITY WITH 2300A
AND PREVIOUSLY PRODUCED
THERMOMETERS
604-37. Option 21X0A-004 is not intended to be used
with a thermometer that is a part of a 2300A Scanning Sys-
tem. In a 2300A system, an Option 2300A-005 or Option
2300A-006 should be installed in the 2300A for connection
to the IEEE-488 bus. Option 2300A-005 is for output only,
similar to Option 21 X0A-004 operation. Option 2300A-006
additionally provides remote control of the 2300A. Options
2300A-005 and 2300A-006 use the 2XXXA-522 and 1120A
for connection to the IEEE bus.
CAUTION
Option 21 X0A-004 is not compatible with a
2300A Scanning System. Such use may cause
channel numbers to be displaced by one read-
ing, and each reading may be output twice.
604-38. Option 21X0A-004 is not directly compatible
with the earliest version of the 2180A and 2190A thermome-
ters. A choice of either of the two modifications described
below provides compatibility. To identify the early version
of thermometer, observe the thermometer display as it is
turned on. If the display characters begin with “2180” or
604-6
“2190”, the thermometer is an early version. Newer versions
begin with “800” or “900.”
604-39. If your thermometer is an early version, either of
the following two modifications may de pertorred:
|. The microprocessor in the ihermomeier can ce
replaced with a newer version. Contact your local
John Fluke Service Center to order the latest
2180A or 2190A standard versions.
a. When you are updating a 2180A to the latest
version, be aware there are changes in the avail-
able choice of Resistance Temperature Detec-
tor (RTD) linearizations. If you require the
original linearizations, order a special retrofit
kit Model 2180A/ AYK. (P/N 796953)
Ge
. When you are selecting from the latest versions
of 2190A linearizations, be aware tha: an
enhanced microprocessor retrofit kit is aiso
available. The enhanced retrofit kit provides 15
thermocouple types. Order Model 2190A /AMK
(P/N 763292)
2. A modification to Option 21 X0A-004 may aiter-
natively be performed. Contact your local John
Fluke Service Center and arrange for the instalia-
tion of a 2180A-4021W (JF P/N 539288) onto
Option 21X0A-004. QI and Q3 are removed from
the pca and replaced by the modification circuit.
This modification makes Option 21 X0A-004
compatible with all versions of 2180A and 2190A
thermometers. A +5 volt connection 15 provided
next to U2 to provide power to the added modifi-
cation circuit.
604-40. PERFORMANCE TEST
604-41. There are no adjustments or calibration.

606-1. INTRODUCTION
606-2. The 21X0-006 Limits Option gives the 2180A
and 2190A Digital Thermometers the capability of
providing both visual and electrical indications (alarms)
when the temperature measurement exceeds either of a
pair of selectable maximum/ minimum limit values. Also
selectable are, all for a single point, the delta function
(displays the difference between the preset value and the
temperature read), and the maximum/ minimum display
function (the highest or lowest temperature read since the
last reset by the INITIALIZE MAX/ MIN switch).
606-3. The Limits Option is available as factory
installed with initial order or may be ordered as a field
installable kit for addition to the instrument.
606-4. SPECIFICATIONS
606-5. Specifications for the Limits Option, 21X0-006,
are as listed in Table 606-1.

2. Remove the screws on the bottom of the case
that fasten the top and bottom of the PTI case
together and remove the top half of the case.
3. Remove the hole plugs from the Limits section
of the front panel and attach the standoffs supplied
with the option to the front panel.
4. Position the Limits PCB so that the
thumbwheel LED and pushbutton switch line up
with the applicable front panel ports.
5. Attach the Limits PCB to the Main PCB using
the screws supplied with the option.
6. Connect the cable on the Limits PCB to J4 on
the Main PCB.
7. Replace the PTI cover on the instrument and
reconnect to input power sources, if required at this
time.

21X0A-006
606-8. OPERATING NOTES
606-9. Installation of the Limits Option enables the low
current single contact relay (KI) on the thermometer
Main PCB. The contact points are available on a rear
panel connector block.
NOTE
Once installed there are no provisions for
disabling the Limits Option. If a temperature
display is desired without the relay or LED
indications select one of the Limits Functions
(> or É) and the maximum setting on the
numeric thumbwheel switches.
606-10. OPERATION
606-11. The position and general description of the
Limits Option front panel controls is given in Section 2. A
more detailed description of the three functions is given in
the following paragraphs.
606-12. Limits Function
606-13. The limits function is enabled when the function
portion of the thumbwheel is set in either the < or >
position. The front panel LED illuminates and the rear
panel relay contacts close when either of the preset
conditions are met. In the greater than (>) function the
indications (LED and relay contacts) result from any
temperature reading that exceeds the value set on the limit
thumbwheel. The less than (<) function gives its
indication when the temperature read by the thermometer
1$ equal to, or less than, the value set on the limit
thumbwheels. The thumbwheel LSD is a whole number,
fractional entries cannot be made.
606-14. Delta Function
606-15. Whenthedelta( A )functionisselected on the
thumbwheel the thermometer display reads the difference
between the temperature at the thermocouple and the
whole number setting of the thumbwheels. The formula
used for the computation is:
T displayed = T at thermocouple - T thumbwheel setting
(in degrees)
606-16. MINIMUM/MAXIMUM Display
Function
606-17. The microcomputer acculmulates and stores
the highest and lowest temperatures recorded since the
last reset. When the maximum ( Æ ) function is selected
the highest temperature recorded and stored in the
microcomputer is displayed. Selection of the minimum
function ( Y ) displays the lowest recorded temperature
606-2
since the last reset. To record the current temperature to”
either function, select the applicable function and denress
the front panel reset switch.
606-18. THEORY OF OPERATION
606-19. The -006 Option ««pri=a he thermometer wit:
the function and numeric data selected on the tront папе!
mechanical thumbwheel switches. When a Limits
function 1s selected the data is stored for comparison on
the option pcb. All communication between the option
and the thermometer is done on the clocked serial
accessory bus. This bus transmits and receives addresses.
thumbwheel data, reset data, and limit status. Refer to the
schematic in Section 8 during the Theory of Operation
discussion.
606-20. Addressing
606-21. Each of the options on the bus is addressed with
a different code. The thermometer uses the address 6” tc
talk to the Limits Option. To talk to any option. the
WRTADR (P4-3) line must be brought low with WRT
(P4-4) high, followed by the applicable four address bits
applied to the DATA (P4-5) line in succession, toggling
DCLK (P4-6) for each bit. This clocks the address into the
shift register (U2-15) where it is compared to the Limits
Option address and, 1f valid, (U1-1 low) enables the gates
required to shift data to the thermometer (U 5-11) and into
the limits option (U5S-2). Details of the data transfer are 11:
subsequent paragraphs.
606-22. Limits Option Outputs
606-23. Before thethermometer can input data from the
Limits Option the Limits circuitry must be addressed as
described previously (Ul-1 low). Once addressed. th=
WRTADR and WRT lines go high. The low to high
transition of WRTADR (U3-6) loads the shift registers
from the thumbwheeland RESET switches. The two lines
enable the output data line (U1-13) and as the :he
thermometer accepts the data it clocks the serial outrur
shift registers with DCLK, transferring the data irom tie
shift register to the thermometer.
606-24. Inthe thermometer the data 1s processed By ise
microcomputer to perform the proper action. Für the
limits function, the output is compared to the state ot the
limits and, if exceeded, the indicator illuminated and the
relay energized. For the delta function. the temperature is
compared against the transmitted value and ‘he
difference displayed. If either the maximum or minimum
function 1s selected the stored value 1s displayed. but, in
addition, the status of the RESET switch is checked.
606-25. Limits Option Inputs
606-26. The thermometer transmits to the Limits
Option only the limits exceeded status. After the option
has been addressed, (Ul-1) WRTADR goes high to
disable the addressing circuit (U4-13), while WRT stays
low to enable the limits exceeded input (U5-8) so that
DCLK can clock the data into the latch (U5-1). A limits
exceeded indication clocks a high into the latch resulting
in a low at the output (U6-12) to turn on CRI. The limits
not exceeded or another function selected, loads a low
into the latch to turn off the indicator.
606-27. CALIBRATION
606-28. The Limits Option has no variable components
and does not require calibration.
21X0A-006
606-29. TROUBLESHOOTING
606-30. Troubleshooting for the 2190A Option -006,
Limits, consists of the tabular flow chart in Table 606-2.
When a step on the flow chart is completed, check for a
decision transfer. If no decision is required, perform the
next step of the table in sequence.
606-31. LIST OF REPLACEABLE PARTS
606-32. Table 606-3 is a list of replaceable parts for the
Limits Option. Refer to Section 5 for an explanation of
the columnar entries.
