Dry-Block Calibrator
Introduction
The Fluke 500 Series Dry-Block Calibrators may be used as portable or benchtop
instruments for calibrating temperature probes.
These dry-block calibrators feature interchangeable inserts to accommodate a wide range
of temperature probe diameters.
The calibrator controller uses a precision, platinum RTD as a sensor. Models 514 and 517
use thermoelectric modules (TEDs) to control the heating and cooling of the well. Model
515 uses a solid state relay (triac) to control the heating of the well. Model 518 uses both
TEDs and a triac to control heating and cooling.
The LED display continuously shows the current well temperature. You can use the front
panel buttons to easily set any temperature within the range specified for the calibrator.
The dry-block calibrators are designed for portability, moderate cost, and easy operation.
To safely and accurately calibrate temperature sensors and devices, familiarize yourself
with the calibrator’s safety guidelines and operating procedures described in this manual.

Dry-Block Calibrator
Environmental Conditions
Environmental Conditions
Although these calibrators have been designed for optimum durability and trouble-free
operation, they must be handled with care. The calibrator should not be operated in an
excessively dusty or dirty environment. Maintenance and cleaning recommendations are
given in the “Maintenance” section of this manual.
The calibrators operates safely under the following conditions:
•
Temperature range: 5 °C to 50 °C (41 °F to 122 °F)
•
Ambient relative humidity: 15 % to 50 %
•
Pressure: 75 kPa to 106 kPa
•
Mains voltage: ±10 % of nominal
•
Altitudes below 2000 m
•

Safety Guidelines
Warning
To avoid personal injury or death, follow these guidelines:
•
Inspect the calibrator for damage before each use. Do not use the
calibrator if it appears damaged or operates abnormally.
•
Use only a grounded ac mains supply of the appropriate voltage to
power the calibrator.
•
Do not operate the calibrator without a properly grounded, properly
polarized power cord.
•
Do not connect the calibrator to a non-grounded, non-polarized outlet.
•
Do use a ground fault interrupt device.
•
Before working inside the calibrator, turn off the power and disconnect
the power cord.
•
Temperatures above 70 °C (158 °F) are considered hazardous. Use
extreme care when working with these temperatures. Observe all
warnings and cautions given in this manual.
•
Before initial use, after transport, and anytime the dry-block has not
been energized for more than 10 days, the calibrator must be energized
for a dry-out period of 1 to 2 hours before it can be assumed to meet all
of the safety requirements of the IEC 1010-1.
•
Do not operate the calibrator near flammable materials.
•
Always replace the fuse with one of the same rating, voltage, and type.
•
Always replace the power cord with an approved cord of the correct
rating and type.
•
Do not operate the calibrator in an excessively wet, oily, dusty, or dirty
environment. Always keep the well and inserts clean and clear of
foreign material.
•
Do not use fluids to clean out the well.
•
Do not touch the calibrator’s probe handle.

•
Always be aware of the well temperature. The temperature of the probe
terminal is the same as the temperature shown on the display. For
example, if the unit is set to 600 °C and the display reads 600 °C, the
well is at 600 °C.
•
Do not touch the metal on the top of the calibrator while the calibrator is
hot. The area around the probe terminal can get extremely hot.
•
Insert and remove probes only when the calibrator is set at
temperatures less than 50 °C.
•
The air over the well can get hot enough to burn you.
•
Do not turn off the calibrator at temperatures higher than 100 °C. Select
a set-point less than 100 °C and let the calibrator cool down before
turning it off.
•
Do not remove inserts while the calibrator temperature is greater than
50 °C. Inserts are at the temperature shown on the display.
•
Always use the tongs supplied with the calibrator to remove the inserts.
After removing probes, always place the probes on a temperatureresistant surface until the probes are at room temperature.
•
Always carry the calibrator in an upright position to prevent the inserts
from dropping out.
•
Overhead clearance is required. Do not place the calibrator under a
cabinet or any other structure.
•
Always leave enough clearance above the calibrator to allow for safe
and easy insertion and removal of probes.
•
Always operate the instrument at room temperatures between 41 °F and
122 °F (5 °C to 50 °C). Allow sufficient air circulation by leaving at least
6 inches (15 cm) of clearance around the calibrator.
•
Do not place aluminum inserts in high-temperature calibrators that can
heat up above 400 °C.
•
Do not use the calibrator for applications other than calibration work.
•
Do not use the calibrator in environments other than those listed in this
manual.
•
Use extra caution when operating the calibrator at high temperatures
for extended periods of time.
•
Unattended operation at high temperatures is not recommended.
•
The high temperatures present in the calibrator may result in fires and
severe burns if safety precautions are not observed.
•
Do not use the calibrator without adequate training.
•
Do not use in wet environments.
Dry-Block Calibrator
Safety Guidelines
Caution
To avoid possible damage to the calibrator or the probes being
calibrated:
•
•
Do not change the calibration constants from the factory settings. The
factory settings are important for the safety and proper operation of the
calibrator.
•
Always turn off the calibrator immediately if the mains power supply
fluctuates. Power fluctuations could damage the calibrator. Wait until
the power has stabilized before re-energizing the calibrator.
•
Never allow foreign material into the probe holes. Fluids and other
materials can damage the calibrator or cause binding and damage to
your probe.
•
Allow for probe expansion inside the well as the dry block heats.
•
Do not calibrate probes whose handles can be damaged by the hot air
above the well. Use of a probe shield is recommended. Check the probe
handle temperature limit before calibration.
•
Do not place into the well any objects other than the inserts supplied for
the calibrator.
•
The master reset sequence should be performed only by authorized
personnel if no other action is successful in correcting a malfunction.
You must have a copy of the most recent Report of Calibration to
restore the calibration parameters.
•
For Model 517, always use the well insulator. See “Well Insulator for
Model 517”.
•

Getting Started
Unpacking
Unpack the calibrator carefully and inspect it for any damage that may have occurred
during shipment. If there is shipping damage, notify the carrier immediately.
Verify that the following components are present:
•
Dry-block calibrator
•
Insert (One insert, specified by the customer, is include with the calibrator. See
Tables 6 through 8.)
•
One set of tongs
•
Power cord
•
Users manual
•
Well insulator (517 only)
•
RS-232 cable
Set-up
Warning
To avoid personal injury:
Before initial use, after transport, and anytime the dry-block
has not been energized for more than 10 days, the calibrator
must be energized for a dry-out period of 1 to 2 hours before it
can be assumed to meet all of the safety requirements of the
IEC 1010-1.
Place the calibrator on a flat surface surrounded by at least 6 inches (15 cm) of free space
with no overhead obstructions. Carefully slide the insert into the well. Inserts should have
the smallest hole diameter possible that allows the probe to slide in and out easily. Inserts
of various sizes are available from Fluke. The well must be clear of any foreign objects,
dirt and grit before the insert is installed. Install the insert so the two small tong holes are
positioned upward.
Power
Verify that the nominal ac voltage corresponds to that indicated on the back of the
calibrator. Typically this will be 115 VAC (±10 %), 50/60 Hz or 230 VAC (±10 %),
50/60 Hz. Plug the calibrator power cord into a grounded ac outlet of the proper voltage,
frequency, and current capability.
For Models 514, 515, and 517, turn the calibrator on using the power switch on the rear
panel.
For Model 518, use the power switches on the front panel to turn on the hot and cold
sides at the same time. (An error occurs if both sides are not turned on within 5 seconds
of each other. Refer to Table 11.)
The fan should begin quietly blowing air through the calibrator and the front panel
display should illuminate after 3 seconds. After a brief self-test, the controller should
begin normal operation. The calibrator will begin to heat to the previously programmed
temperature set-point. The front panel LED display will indicate the actual dry-block
temperature. If the unit fails to operate, check the power connection.

Safety Guidelines
Changing the Supply Voltage and Fuses on Models 515 and 517
To change the supply voltage and fuses on Models 515 and 517, proceed as follows:
Warning
To avoid electric shock, burns, or damage to equipment:
•
Always replace the fuses with ones of the correct rating,
voltage, and type.
•
Always replace the power cord with an approved cord of the
correct rating and type.
1. Turn off the calibrator and unplug it from the ac outlet.
2. Insert a flat-blade screwdriver into the slot at the top of the power entry module
(PEM). (Refer to Figure 17 under “Replacing the Fuses” in the “Care and
Maintenance” section.) Gently open the module to access the fuse holder.
3. Remove the fuse holder. Replace the fuses with the correct fuses for the new voltage.
4. Replace the fuse holder, turning it so that the correct voltage shows in the voltage
window on the PEM. Close the PEM.
5. Model 515: On the back of the calibrator, switch the HEATER VOLTAGE
SELECTOR to the correct voltage.
Note
For proper operation, the HEATER VOLTAGE SELECTOR and PEM
voltage window must match.
6. You may need to change the power cord to fit the ac outlet. Compatible power cords
include the following:
•
230 VAC Europe: 10 A approved cord with a CEE 7/7 plug (Schuko)
•
230 VAC United States: 15 A approved cord with a NEMA 6-15 straight-blade
plug
•
115 VAC United States: 15 A approved cord with a NEMA 5-15 plug
7. Connect the calibrator to the ac outlet.
Changing the Display Units
The calibrator can display temperatures in degrees Celsius or Fahrenheit. The
temperature units are set to Celsius at the factory. To switch between temperature units,
use one of the following methods:
Press UP for 2-3 seconds until the display flashes.
Or
1. Press SET three times to display the units; then press UP or DOWN to change the units
2. Press SET to store the change or EXIT to proceed without storing the change.
11
500 Series
Users Manual
Setting the Temperature
The later section “Setting the Temperature Set-Point” explains in detail how to set the
temperature set-point on the calibrator using the front panel keys. The procedure is
summarized here.
1. Press SET twice to access the set-point value.
2. Press UP or DOWN to change the set-point value.
3. Press SET to program in the new set-point.
4. Press and hold EXIT to return to the temperature display.
When you change the set-point temperature, the controller switches the well heater on or
off to raise or lower the temperature. For Models 514, 515, and 517 the cycle indicator, a
two color LED, will also indicate on (red and heating) or off (green and cooling). The
displayed well temperature gradually changes until it reaches the set-point temperature.
The well may require 5 to 30 minutes to reach the set-point depending on the span.
Another 5 to 10 minutes is required for the temperature to stabilize. Table 5 shows the
heating and stabilization times required for the 500 Series Calibrator models.

Constant Temperature Block Assembly
The constant temperature block provides a relatively constant and accurate temperature
environment for the sensors to be calibrated. The block in Models 514 and 517 is made of
aluminum. The block in Model 515 is made of aluminum-bronze. The block in the cold
side of Model 518 is aluminum and the block in the hot side is aluminum-bronze. The
holes in the blocks may be used for sensors of that size or may be reduced with various
sized inserts. Attached to the block in Models 514, 517, and the cold side of 518 are
Peltier thermoelectric modules that heat or cool the block to maintain a constant
temperature. A high-quality platinum RTD embedded in the block senses the temperature
and provides feedback to the temperature controller.
Figures 6 through 8 show the blocks for each model of calibrator.

Well Insulator for Model 517
Model 517 includes a well insulator made of white polymer foam that fits into the
opening above the block (see Figure 9). The well insulator has three purposes:
•
It insulates the top of the block to minimize the vertical temperature gradient in the
block.
•
It insulates the top of the block to prevent excessive heat from flowing into or out of
the block, which may prevent it from reaching its minimum or maximum
temperatures.
•
It shields the top of the block from open air, thus reducing the potential for excessive
water condensation on the block. Excessive water on the block can cause corrosion
over a long period of time. Water condensation that freezes expands and can damage
the block.
For these reasons, Model 517 must always have the well insulator installed during
operation. The well insulator fits snugly into the rectangular cavity just above the block.
For best results, do not push the well insulator all the way down into the cavity. Instead,
leave the top of the well insulator flush with the top of the cavity. Insert probes through
the slots in the well insulator.

Tips for Calibrating Probes
Following are some tips for calibrating probes:
•
Probes inserted into the block may be compared to the well temperature displayed on
the front panel of the calibrator. The probes should be inserted the full depth of the
well since the temperature at the bottom of the well most closely agrees with the
displayed temperature.
•
For greater accuracy when using a calibrator with multiple wells, the probes may be
compared to a reference thermometer inserted into the block. The reference
thermometer may be inserted into one hole while the probes to be calibrated are
inserted into another. A disadvantage to this method is that temperature variations
throughout the block may cause a small temperature difference between one hole and
another, which can cause errors.
•
Using the same hole for the reference thermometer and the test probe may produce
better results. This, however, requires switching the probes, which takes more time.
You must allow a few minutes after inserting the probes for the temperature to
stabilize before making measurements. Because of temperature variations along the
depth of the well, best results are obtained when comparing probes of similar
construction and inserting them the same depth into the well.
•
Using the same diameter probes, switch them between holes several times to reduce
the uncertainty of the measurement caused by fit and well gradients. For precise
measurements, you should determine the measurement uncertainty.
Operating the Calibrator
This section discusses in detail how to operate the calibrator using the front control panel.
Using the front panel keys and LED display, you can do the following:
•
Monitor the well temperature.
•
Reset the heater cut-out.
•
Set the temperature set-point in degrees C or F.
•
Set a scan rate for the well temperature.
•
Use the display hold feature to test a thermal switch.
•
Set up ramp and soak programs.
•
Monitor the heater output power.
•
Adjust the controller’s proportional band.
•
Program the probe calibration parameters, operating parameters, serial and IEEE-488
interface configuration, and controller calibration parameters.
Figures 10 through 12 summarize the operation of the control panel.

Monitoring the Well Temperature
The digital LED display on the front panel allows direct viewing of the actual well
temperature. This temperature value is what is normally shown on the display. The units,
C or F, of the temperature value are displayed at the right, as shown below:
20.00 C
Well temperature in degrees Celsius
You can access the temperature display function from other functions by holding down
the EXIT key for 2 seconds.
Resetting the Heater Cut-Out
If the over-temperature cut-out has been triggered, power to the heater is shut off and the
temperature display will flash the following message:
cut_out
Indicates cut-out condition (flashing display)
The message continues to flash until the temperature is reduced and the cut-out is reset.
The cut-out must be reset by the operator after the temperature falls below the set-point.
When the cut-out has been triggered, the display flashes “cut-out” until you reset the cutout. To access the reset cut-out function press SET.
Access the cut-out reset function
SET
The display indicates the reset function:

SET
Resetting the cut-out also switches the display to the set temperature function. To return
to displaying the well temperature, press EXIT. If the cut-out circuit is still in the overtemperature fault condition the display continues to flash “cut-out”. The well temperature
must drop a few degrees below the cut-out set-point before the cut-out can be reset.
Setting the Temperature Set-Point
You can set the temperature set-point to any value within the calibrator’s operating range
and with resolution as given in the specifications. Be careful not to exceed the safe upper
temperature limit of any device inserted into the well. The high limit should be properly
adjusted to help prevent this occurrence.
Setting the temperature involves two steps: (1) selecting the set-point memory and (2)
adjusting the set-point value.

Testing a Thermal Switch
The calibrator has a switch test function that allows an external switch to freeze the
displayed temperature and stop the set-point from scanning. This function is useful for
testing thermal switches. This section explains the switch test and provides an example
describing how to set up and use this feature.
Enabling the Switch Test
To enable the switch test feature, press UP when the temperature is displayed. The switch
test display shows the temperature on the right and the switch status on the left. The
status “c” means the switch is closed; “o” means the switch is open. The status flashes
when the switch is active (opposite the normal position). When a new set-point is
selected, the new status becomes the normal position.

Switch Wiring
Wire the thermal switch to the back of the calibrator at the two terminals labeled
“DISPLAY HOLD”. You can connect the switch wires to the terminals either way.
Internally, the black terminal connects to ground; the red terminal connects to +5 V
through a 100 kΩ resistor. The calibrator measures the voltage at the red terminal and
interprets +5 V as an open switch and 0 V as a closed switch.
Switch Test Example
This section describes how to set up and operate the calibrator for an example application
of the switch test feature.
In this example, you have a thermal switch that is supposed to open at about 75 °C and
close at about 50 °C. You can use the switch test feature and the scan function to test the
accuracy and repeatability of the switch’s response. You can read measurements on the
display or, preferably, collect the data using a computer connected to the RS-232 port.
To set up the test, follow the steps below:
1. Connect the switch wires to the “DISPLAY HOLD” terminals on the back of the
calibrator. Place the switch in the well.
2. Enable the set-point scanning by setting the scan to “ON” in the primary menu (see
“Enabling or Disabling Scanning”).
3. Set the scan rate to a low value, 1.0 °C/ min for example (see “Scan Rate”). If the
scan rate is too high you may lose accuracy because of transient temperature
gradients. If the scan rate is too low the duration of the test may be longer than
necessary. You may need to experiment to find the best scan rate.
4. Set the first program set-point to a value above the expected upper switch
temperature, for example 90 °C.
5. Set the second program set-point to a value below the expected lower switch
temperature, for example 40 °C.
6. Collect data on a computer connected to the RS-232 port. Refer to “Digital
Communications” for instructions on configuring the RS-232 communications
interface.

Secondary Functions
Functions used less often are available in the secondary menu. You can access the
secondary menu by pressing SET and EXIT simultaneously and then releasing the buttons.
The first function in the secondary menu is the heater power display.
Monitoring the Heating Power
The temperature controller controls the temperature of the well by heating or cooling the
well with the thermoelectric modules or triacs (depending on the model). The amount of
heating or cooling power depends on the temperature set-point of the well. This heating
(or cooling) power value may be estimated by watching the red/green LED or read
directly from the digital display. By knowing the amount of heating, the user can tell if
the calibrator is heating up to the set-point, cooling down, or maintaining a constant
temperature. The fluctuations in the heater power percentage represent the stability of the
well temperature. With good stability, the heating power percentage should not fluctuate
more than ±1 % within one minute.
The heater power display is accessed in the secondary menu. Press SET and EXIT
simultaneously, then release the buttons. The heater power is displayed as a percentage of
full power.

33
500 Series
Users Manual
For Model 515 and the hot side of 518, zero percent means maximum cooling (no heater
power is applied). The power percentage is never negative for these models.
To exit out of the secondary menu press EXIT. To continue on to the proportional band
setting function press SET.
Setting the Proportional Band
In a proportional controller such as this, the heater output power is proportional to the
well temperature over a limited range of temperatures around the set-point. This range of
temperature is called the proportional band. At the bottom of the proportional band the
heating is 100 %. At the top of the proportional band the cooling is 100 %. Thus, as the
temperature rises the heater power is reduced, which tends to lower the temperature back
down. In this way, a fairly constant temperature is maintained.
The well’s temperature stability and response time depend on the width of the
proportional band. See Figure 13. If the band is too wide the well temperature will
deviate excessively from the set-point due to varying external conditions. This is because
the heater power changes very little with temperature and the controller cannot respond
very well to changing conditions or electrical or thermal noise in the system. If the
proportional band is too narrow the temperature may swing back and forth because the
controller overreacts to temperature variations. For best control stability the proportional
band must be set for the optimum width.
The proportional band width is set at the factory and printed on the Report of Calibration
included with all models. The proportional band width may be altered by the user if he
desires to optimize the control characteristics for a particular application.
The proportional band width is easily adjusted from the front panel. The width may be set
to discrete values in degrees C or F depending on the selected units. The proportional
band adjustment is accessed within the secondary menu. Press SET and EXIT to enter the
secondary menu and show the heater power.

Dry-Block Calibrator
Methods for Calibrating Probes
Calibration Parameters
You can access a number of the instrument calibration constants, such as CTO, RO,
ALPHA, DELTA, and BETA (Models 514, 517, and 518). These values are set at the
factory and must not be altered. The correct values are important to the accuracy and
proper and safe operation of the calibrator. Access to these parameters is available only
so that if the controller’s memory fails, you can restore these values to the factory
settings. The report of calibration lists these constants and their settings.
Caution
Do not change the values of the calibration constants from the
factory set values. The correct setting of these parameters is
important for the safety and proper operation of the calibrator.
The calibration parameters menu is indicated by the following:
CAL
Calibrations parameters menu
Press SET five times to enter the menu.
Parameter CTO sets the calibration of the over-temperature cut-out. This parameter is
adjusted with an internal potentiometer only by qualified service technicians. For Models
514 and 517, this parameter should read between 150 and 170. For Model 515, this
parameter should read between 610 and 630. For Model 518, the cold side does not have
the CTO parameter and the hot side should read between 680 and 690.
Methods for Calibrating Probes
For optimum accuracy and stability, allow Models 514 or 517 to warm up for 10
minutes after power-up. Allow Models 515 or 518 to warm up for 30 minutes. After
warm-up, allow adequate stabilization time after reaching the set-point temperature.
After completing calibration, allow the block to cool before switching the power off.
For information on automating your testing, contact Fluke Corporation.
Direct Calibration
Direct calibration involves testing a probe directly against the dry-block’s temperature
display. The method has the advantage of being quick and easy.
Insert the probe to be calibrated into the well of the dry-block calibrator. The probe
should fit snugly in the calibrator, yet should not be so tight that it cannot be easily
removed. Remove any dirt or grit that may cause the probe to jam in the insert. For best
results, insert the probe to the full depth of the well. Once the probe is inserted into the
well, allow adequate stabilization time to allow the test probe temperature to settle as
described. Once the probe has settled to the temperature of the well, it may be compared
to the calibrator display temperature. The display temperature should be stable to within
0.1 °C for best results.
Caution
Never allow foreign material into the probe holes. Fluids and
other materials can damage the calibrator or cause binding and
damage to your probe.
37
500 Series
Users Manual
Comparison Calibration
Comparison calibration involves testing a probe against a similar reference probe. This
method can be more accurate because errors due to dry-block tolerances, the stem effect,
and temperature gradients are reduced.
After inserting the probes to be calibrated, allow sufficient time for the probes to settle
and the temperature of the dry-block to stabilize.
Both the reference probe and the probe under test should be the same size and
construction. Probes with different lengths, diameters and materials have different stem
effects, causing an unknown temperature difference. All dry-blocks have horizontal and
vertical gradients that change with temperature. This is an unknown variable that can be
factored out if probes are the same type, length, diameter, and material. Probes should be
inserted to the same depth in the well.
Use the following procedure to calibrate a probe against a reference while eliminating
error due to temperature gradients between wells.
1. Place the reference probe in one well.
2. Place the probe to be calibrated in another well.
3. After allowing the probe temperatures to settle, take a temperature reading from each.
4. Swap the locations of the reference probe and probe under test. Allow plenty of time
for thermal settling.
5. Make another set of temperature readings from the reference probe and the probe
under test.
6. Average the two readings of the reference probe. Average the two readings of the
probe under test. Averaging the two readings eliminates error due to temperature
gradients between the two wells.
7. You may now compare the averaged reading of the probe under test with the
averaged reading of the reference probe.
For best results repeat the test several times at the same temperature and at different
temperatures.
You can use this method with different types of probes but you must determine the
uncertainty of the measurement.
Calibrating Multiple Probes
Fully loading the calibrator with probes increases the time required for the temperature to
stabilize after inserting the probes. Be sure that the temperature has stabilized before
starting the calibration.
You can calibrate multiple probes simultaneously by using either the direct or
comparison calibration method. Stem effect will cause less error in the comparison
calibration method than with the direct calibration method.
38
Dry-Block Calibrator
Dry-Block Characteristics
Dry-Block Characteristics
Understanding the thermal characteristics of the dry-block calibrator can help you
achieve the best accuracy and efficiency possible.
Vertical Gradient
Heat losses from the top of the calibrator create a vertical temperature gradient in the
well. The heater has been applied to the block in a way that compensates for nominal heat
losses from the top of the dry-block and minimizes vertical temperature gradients.
However, actual heat losses will vary depending on the number and types of probes
inserted into the calibrator and the block temperature. For best results, insert probes the
full depth of well.
Stabilization and Accuracy
The stabilization time for the dry-block calibrator depends on the conditions and
temperatures involved. Table 5 near the beginning of this manual shows the heating and
stabilization times for each model of the calibrator.
Another period of stabilization is required after a cold probe is inserted into a well. The
stabilization time depends on the magnitude of the thermal disturbance and the accuracy
required. For example, a ¼ inch diameter room-temperature probe inserted into a 300 °C
hole will take approximately 5 minutes to be within 0.1 °C of its set-point and will take
10 minutes to achieve maximum stability.
You can decrease the calibration time by knowing how soon to make measurements.
These times can be established by making typical measurements at the desired
temperatures with the desired test probes.
Digital Communication Interface
The dry-block calibrator can communicate with and be controlled by other equipment
through the digital interface. You can use remote communications equipment to set the
set-point temperature, monitor the temperature, and access any of the other controller
functions. Two types of digital interface are available: the RS-232 serial interface and the
optional IEEE-488 GPIB interface.
RS-232 Communications
The calibrator is installed with an RS-232 serial interface that allows serial digital
communications over fairly long distances. With the serial interface the user may access
any of the functions, parameters and settings discussed under “Operating the Calibrator”,
with the exception of the baud rate setting.
For Model 518, the baud rate, duplex made, and linefeed are set using the cold side
commands (C:). The sample rate can be set for both the cold and hot side.
Cable Wiring and Data Protocol
The serial communications cable attaches to the DB-9 connector at the back of the
calibrator.
Figure 14 shows the pin-out of this connector and suggested cable wiring. To eliminate
noise, the serial cable should be shielded with low resistance between the connector
(DB9) and the shield.
The serial interface uses 8 data bits, one stop bit, and no parity.

RS-232 Operation
Once you have attached the cable and properly set up the interface, the calibrator will
immediately begin transmitting temperature readings at the programmed rate. The setpoint and other commands may be sent by a remote device to set the temperature setpoint and view or program the various parameters. The interface commands are discussed
under “RS-232 and IEEE-488 Interface Commands”. All commands are ASCII character
strings terminated with a carriage-return character (CR, ASCII 13).
IEEE-488 Communications
The IEEE-488 interface is available as an option. Instruments supplied with this option
may be connected to a GPIB type communication bus, which allows many instruments to
be connected and controlled simultaneously. To eliminate noise, the GPIB cable should
be shielded.

instrument interprets either a carriage return or linefeed as a command termination during
reception.
IEEE-488 Operation for Models 514, 515, and 517
Commands may now be sent via the IEEE-488 interface to read or set the temperature or
access other controller functions. All commands are ASCII character strings and are
terminated with a carriage-return (CR, ASCII 13). Interface commands are described in
the section “RS-232 and IEEE Interface Commands”.
IEEE-488 Operation for Model 518
The IEEE-488 communication for Model 518 is managed by the calibrator’s serial
connection and converted to IEEE via an external conversion box. Cables are provided
for connection to a PC and to the instrument.
The IEEE converter box is configured at the factory and tested using IEEE address 22.
Refer to the converter box manual, which is supplied with the box, for instructions on
changing this address.
Note that for Model 518, all commands should be proceeded by a “C:” for the cold side
or an “H:” for the hot side. Refer to Table 10 for a complete set of IEEE-488 commands.

Digital Communication Interface
RS-232 and IEEE-488 Interface Commands
The commands for accessing the calibrator functions via the digital interfaces are shown
in Table 10.
These commands are used with both the RS-232 serial interface and the IEEE-488 GPIB
interface. In either case, the commands are terminated with a carriage-return character.
The interface makes no distinction between upper and lower case letters, hence either
may be used. Commands may be abbreviated to the minimum number of letters that
defines a unique command.
A command may be used to either set a parameter or display a parameter depending on
whether or not a “=” character followed by a value is sent with the command. For
example “s”<CR> returns the current set-point and “s=50.00”<CR> sets the set-point to
50.00 degrees.
In the following list of commands, characters or data within brackets, “[” and “]”, are
optional for the command. A slash, “/”, denotes alternate characters or data. Numeric
data, denoted by “n”, may be entered in decimal or exponential notation.
Spaces may be added within command strings and will be ignored. Backspace (BS,
ASCII 8) may be used to erase the previous character. A terminating CR is implied with
all commands.
Note
For Model 518, all commands are preceded by either a “C:” for cold or an
“H:” for hot. If the “C:” or “H:” are not used with the command, the
command accesses the cold side functions.

Dry-Block Calibrator
Calibrating Models 514, 517, and 518 (cold side)
Calibrating Models 514, 517, and 518 (cold side)
The dry-block calibrator should be calibrated at regularly scheduled intervals by
qualified, authorized personnel in accordance with your company’s policy. Accuracy
specifications apply for a one-year calibration interval. Following is the recommended
calibration procedure for Models 514 and 517 and the cold side of Model 518.
Calibration Equipment
Calibration requires a standard thermometer with acceptable accuracy that fits properly
into one of the reference holes in the block. Recommended equipment includes a
laboratory grade PRT (platinum resistance thermometer) with a length of 230 mm to
300 mm (9 in to 12 in) and a diameter of 4.76 mm or 6.35 mm (3/16 in or 1/4 in). The
combined accuracy of the PRT and the readout should be 0.025 °C or better.
Calibration Parameters
The calibration parameters for the calibrator’s RTD probe are in the secondary menu (see
Figure 11 or 12). The calibration menu is indicated by the following:
CAL
Calibration menu
The calibration parameters are accessed by pressing SET after the name of the parameter
is displayed. Use the UP and DOWN buttons to change the value of the parameter. Press
SET to set the parameter to the new value. Pressing EXIT skips the parameter, ignoring any
changes that may have been made.
The calibration menu contains the following probe parameters:
R0
This probe parameter refers to the resistance of the RTD probe at 0 °C. The value of this
parameter is set at the factory for best accuracy.
ALPHA
This probe parameter refers to the average sensitivity of the RTD probe between 0 °C and
100 °C. The value of this parameter is set at the factory for best accuracy.
DELTA
This parameter relates to the second-order nonlinearity of the sensor. The value is set at
the factory for best accuracy.
BETA
This parameter relates to the higher order nonlinearity of the sensor below 0 °C. The
value is set at the factory for best accuracy.

Calibration Procedure
The calibrator’s accuracy over the full range is determined by the values of the
calibration parameters R0, ALPHA, DELTA, and BETA. Refer to the Report of
Calibration shipped with you calibrator for the temperature range value.
The calibration procedure for Models 514 and 517 involves measuring the error between
the instrument and the reference thermometer at several temperatures throughout the
range, then adjusting the calibration parameters as necessary to reduce the errors to
within acceptable limits. The stated accuracy of the instrument can be found in the
specifications (see Tables 2 through 4). Because of the way the calibration parameters
affect the temperature, the simplest way to proceed is to measure the errors at 0 °C, 100
°C, 140 °C, and –25 °C and adjust R0, ALPHA, DELTA, and BETA at each point
respectively. Follow these steps:
1. If “as found” data is required, then first measure the error at various temperatures
throughout the range (for example –25 °C, 0 °C, 25 °C, 50 °C, 75 °C, 100 °C, and
140 °C). Measure the errors by setting the controller to the desired temperature,
allowing the block to reach the temperature and stabilize, then reading the actual
temperature of the block with the standard thermometer. If the measured errors are all
within acceptable limits, no further action is required. If the accuracy needs
improvement, continue with Step 2.
2. Set the set-point to 0 °C and allow adequate time for the block to reach this
temperature and stabilize. Adjust the R0 calibration parameter to make the block
temperature as measured with the standard thermometer match the set-point. The
approximate ratio between a change in R0 and a change in temperature at 0 °C is
about 0.4 to 1. For example, if the block temperature is high by 0.1 °C at 0 °C then
decrease R0 by 0.04.
3. Set the set-point to 100 °C and allow adequate time for the block to reach this
temperature and stabilize. Adjust the ALPHA calibration parameter to make the
block temperature as measured with the standard thermometer match the set-point.
The approximate ratio between a change in ALPHA and a change in temperature at
100 °C is about 0.00004 to 1. For example, if the block temperature is high by 0.1 °C
at 100 °C then decrease ALPHA by 0.000004.
4. Set the set-point to 140 °C and allow adequate time for the block to reach this
temperature and stabilize. Adjust the DELTA calibration parameter to make the
block temperature as measured with the standard thermometer match the set-point.
The approximate ratio between a change in DELTA and a change in temperature at
140 °C is about -1.7 to 1. For example, if the block temperature is high by 0.1 °C at
140 °C then increase DELTA by 0.17.
5. Set the set-point to –25 °C and allow adequate time for the block to reach this
temperature and stabilize. Adjust the BETA calibration parameter to make the block
temperature as measured with the standard thermometer match the set-point. The
approximate ratio between a change in BETA and a change in temperature at –25 °C
is about -50 to 1. For example, if the block temperature is high by 0.1 °C at –25 °C
then increase BETA by 5.0.
6. Repeat Step 1 to ensure the calibrator is now accurate throughout the full range.

Dry-Block Calibrator
Calibrating Models 515 and 518 (hot side)
Calibrating Models 515 and 518 (hot side)
Model 515 and the hot side of Model 518 are calibrated by adjusting the controller probe
calibration constants R0 and ALPHA so that the temperature of the dry-block as
measured with a standard thermometer agrees more closely with the set-point. The
thermometer used must be able to measure the well temperature with higher accuracy
than the desired accuracy of the dry-block calibrator. By using a good thermometer and
carefully following this procedure, the calibrator can be calibrated to an accuracy of
better than 0.5 °C over a range of 600 °C.
Calibration Points
Adjust R0 and ALPHA to minimize the set-point error at each of two different dry-block
temperatures. Any two reasonably separated temperatures may be used for the
calibration. Refer to the Report of Calibration shipped with your calibrator for the
temperature values used. Improved results can be obtained for shorter ranges when using
temperatures that are just within the most useful operating range of the dry-block. The
farther apart the calibration temperatures, the larger the calibrated temperature range will
be, but the calibration error will also be greater over that range. If for instance 150 °C and
500 °C are chosen as the calibration temperatures, then the calibrator may achieve an
accuracy of ±0.2 °C, for example, over the range 100 °C to 550 °C. Choosing 200 °C
and 300 °C may allow the calibrator to have a better accuracy of ±0.05 °C, for example,
over the range 175 °C to 325 °C; however, outside that range, the accuracy may be only
±0.4 °C.
Measuring the Set-point Error
The first step in the calibration procedure is to measure the temperature errors (including
sign) at the two calibration temperatures. First set the calibrator to the lower set-point
called tL. Wait for the well to reach the set-point and allow 30 to 60 minutes to stabilize at
that temperature. Check the stability with the thermometer. When both the well and the
thermometer have stabilized, measure the temperature with the thermometer and
calculate the temperature error errL, which is the actual well temperature minus the setpoint temperature. If, for example, the calibrator is set for a lower set-point of
tL=200 °C and it reaches a measured temperature of 199.7 °C then the error is –0.3 °C.
Next, set the calibrator for the upper set-point tH. After stabilization, measure the well
temperature and calculate the error errH. For this example, suppose the calibrator was set
for 400 °C and the thermometer measured 400.1 °C giving an error of +0.1 °C.

Computing R0 and ALPHA
Before computing the new values for R0 and ALPHA, the current values must be known.
The values may be found by either accessing the probe calibration menu from the
controller panel or by inquiring through the serial interface. You should keep a record of
these values in case they may need to be restored in the future. The new values R0′ and
ALPHA′ are calculated by entering the old values for R0 and ALPHA, the calibration
temperature set-points tL and tH, and the temperature errors errL and errH into the following
equations:
 err t − errLt H

Ro’ =  H L
ALPHA + 1Ro
tH − tL


 (1 + ALPHA tH )errL − (1 + ALPHA tL )errH

ALPHA’= 
+ 1 ALPHA
tH − tL


If for example R0 and ALPHA were previously set for 100.2695 and 0.0038319
respectively and the data for tL, tH, errL, and errH were as given above then the new values
R0′ and ALPHA′ would be calculated as 100.193 and 0.0038272 respectively. Program
the new values R0 and ALPHA into the controller. Check the calibration by setting the
temperature to tL and tH and measuring the errors again. If desired, the calibration
procedure may be repeated to further improve the accuracy.
Calibration Example
The calibrator will be used between 125 °C and 325 °C and maximum accuracy is desired
within this range. The current values for R0 and ALPHA are 100.000 and 0.0038500
respectively. The calibration points are chosen to be 150.00 °C and 300.00 °C. The
measured well temperatures are 149.943 °C and 299.814 °C respectively. Figure 16
shows how to calculate the new probe constants for this example.

Care and Maintenance
With proper care the calibrator requires very little maintenance. The following guidelines
describe how to care for and maintain your calibrator.
54
•
Avoid operating the instrument in an oily, wet, dirty, or dusty environment.
•
If the outside of the calibrator becomes soiled, it may be wiped clean with a damp
cloth and mild detergent. Do not use harsh chemicals on the surface because the paint
might be damaged.
•
If the ac supply cord is damaged, replace it with a cord with the appropriate gauge
wire for the calibrator’s current rating. If you have any questions, call Fluke
Customer Service for more information.
•
Before using any cleaning or decontamination method except those recommended by
Fluke, check with Fluke Customer Service to be sure that the proposed method will
not damage the equipment.
•
It is important to keep the well of the calibrator clean and clear of any foreign matter.
DO NOT use fluid to clean out the well.
•
The dry-block calibrator should be handled with care. Avoid knocking over or
dropping the calibrator.
•
For dry-blocks with removable inserts, the inserts can become covered with dust and
carbon material. If the buildup becomes too thick, it could cause the inserts to
become jammed in the wells. Avoid this build up by periodically buffing the inserts
clean with a Scotchbrite® fine-grit pad or an emery cloth.
•
If an insert is dropped, examine it for deformities before inserting it in the well. If
there is any chance of the insert jamming in the well, file or grind off the
protuberance.
•
DO NOT slam the probe stems into the well. Doing so can cause a shock to the
sensor.
•
If a hazardous material is spilt on or inside the equipment, you are responsible for
taking the appropriate decontamination steps as outlined by the national safety
council with respect to the material.
•
If the instrument is used in a manner not in accordance with the equipment design,
the calibrator may malfunction or safety hazards may arise.
