Section 1.0 Introduction
Congratulations! Your purchase of the MC6 modu-
lar calibration system equips you to perform a wide
variety of pressure and temperature measurement
applications. The general pressure and temperature
measurement capabilities of the MC6 measurement
system are supplemented by application specific
firmware as well as the availability of optional data
logging capability.
The MC6 products are complete pressure calibration
systems providing: interchangeable pressure ranges,
simultancous measurement and display of two
pressure ranges, measurement and display of current
and voltage. The MC6 system also provides the
ability to perform high accuracy temperature mea-
surement. Conversion between temperature and
pressure measurement can be done in a matter of
seconds and requires no tools.
À standard MC6 system consists of a base unit that
acts as a host for one or two Quick Select modules.
The Quick Select pressure modules are interchange-
able and are available in a wide variety of ranges
from 0.25 inches of water to 10,000 psi. À brief
description of the main components of an MC6
system follows. In addition, a Quick Select module
is available that allows the base unit to work in
conjunction with most any standard RTD tempera-
ture probe.
Section 3 and its various subsections include all the
“information needed to begin using the MC6 system
for basic pressure and temperature measurement.
Higher level functions are detailed in later sections
of this manual. It is strongly recommended that the
pertinent sections of this manual be reviewed prior
to using the MC6 system for higher level and appli-
cation specific measurement and test activities.

Section 1.1 Base Unit Overview
The base unit functions as the host for the Quick
Select pressure and temperature module(s). Each
base unit includes a keypad, microprocessor based
electronics and a two line LCD display. The base
unit displays the measurement data transmitted from
the Quick Select module(s). Measurement outputs
trom two installed Quick Select modules can be
simultancously displayed. Quick Select modules for
the measurement of cither pressure or temperature
can be plugged into either of the 2 module “bays” in
the base unit. Pressure engineering units can be
independently selected from the library of twelve
factory programmed or onc operator designated
engineering unit. Temperature measurement data can
be displayed in degrees Celsius, Fahrenheit, Kelvin
or Rankine. In addition, when used with the GQS-
RTI Quick Select module for temperature measure-
ment with an RTD temperature probe, the MC6
system can display the RTD measurement in terms
of ohms.
In addition to displaying two pressure measurements
simultaneously the operator can elect to display
pressure and temperature or the measured value from
either of the two installed Quick Select modules as
well as either a voltage or mA measurement. This
allows for the easy calibration and test of transduc-
ers, transmitters and switches.
The base unit includes a wide variety of general and
application specific measurement capabilities. These
capabilities allow the MC6 measurement and cali-
bration system to be used for basic pressure and
temperature measurement as well as application
specific pressure measurement activities. Basic
pressure and temperature measurement capabilities
include: max/min recall, operator programmable tare
values, display hold, operator programmable damp-
ing and user sclected engineering units. Application
specific capabilities include; flow velocity measure-
ment, flow volume measurement, leak detection,
lcak rate quantification and switch testing. Optional
data logging, time delayed data logging and pro-
grammable alarms are also available.
Quick Select Modules
Overview
Section 1.2
The Quick Select pressure module 1s a calibrated
pressure measurement device. Quick Select pressure
module units are available in a wide variety of
pressure measurement ranges. Quick Select interface
modules are also available to allow the MC6 base
unit to provide precision temperature measurement
data using standard RTD (Resistance Temperature
Detector) and thermocouple detector temperature
sensing devices. The GOS-RT1 module allows the
MC6 system to function with most common plati-
num, nickel and copper RTDs and the GQS-TC
supports usc of thermocouple temperature detectors.
The Quick Select module communicates with the
base unit via a 10 pin connector. Quick Select
pressure modules slide into the base unit automati-
cally aligning the female 10 pin connector on the
Quick Select pressure module with the male 10 pin
connector in the base unit.
All calibration data is stored in Electrically Erasable
Programmable Read Only Memory (EEPROM)
resident in the Quick Select module. As such, any
Quick Select module can be used in any base unit
and the measurement system will provide measure-
ment accuracy in conformance with the published
specification.
Section 1.2.1 The GQS-1 Quick Select
Pressure Module
GQS-1 Quick Select pressure modules provide
specialized low pressure measurement capabilities.
GQS-1 Quick Select pressure modules incorporate a
micro-machined silicon variable capacitance mod-
ule.
Inside the module there is a micro-machined silicon
diaphragm. This diaphragm 1s between two non-
moving plates on which metal has been sputtered.
The air between the diaphragm and the non-moving
plates acts as an insulator.
As pressure or vacuum is applied to the module, the
diaphragm moves changing the distance between the
diaphragm and the fixed plates. This change in
distance changes the capacitance of the module. It 1s
this variable capacitance that is measured and
correlated to pressure or vacuum during the calibra-
_8-
tlon process.
The module is connected to a circuit board that
generates a linear signal ramp and applies this signal
to the top plate of the module while an equal and
opposite signal 1s applied to the bottom plate.
When the measured pressure 1s balanced. for ex-
ample. when both ports arc opened to atmosphere,
the distance between the diaphragm and both of the
fixed plates is the same. When this is the case, the
signal to the top plate is capacitively coupled to the
equal and opposite signal applied to the bottom plate.
As a result. no signal current will flow through the
center plate (diaphragm). When the diaphragm 1s
moved off center by the application of pressure or
vacuum, the excess current flows through the center
plate to an mput differentiator on the circuit board.
The differentiator translates the frequency of the
module output into a voltage which is scaled over the
full scale range of the module.
GQS-1 modules are available in ranges from 0.25
inches of water through 200 inches of water. These
modules can be configured to provide differential/
gauge or compound pressure measurement capabili-
ties. They are designed for use on clean, dry, noncor-
rosive and nonconductive gases.
Section 1.2.2 The GQS-2 Quick
Select Pressure Module
The GQS-2 Quick Select pressure module incorpo-
rates a micro-machined piezoresistive strain gauge
module. This technology takes advantage of the fact
that, when put under stress, (as with the flexing of a
diaphragm under pressure or vacuum) the resistive
properties of a piece of silicon will change. In the
manufacturing process resistors are deposited in a
silicon substrate. The resistors are typically config-
ured in a wheatstone bridge orientation. When
positioned in this fashion, the output will be near
zero when no pressure (stress) 1s applied and will
increase in a near linear fashion with the application
of pressure or vacuum. The reverse side of the
substrate 1s etched to provide the required diaphragm
thickness for the given pressure range.
When power is applied to the module the level of
resistance across the wheatstone bridge will change in
proportion to the level of pressure applied. The output
from the module 1s extremely repeatable and has
minimal hysteresis due to the fact that the module
substrate is silicon. The module output 1s then ampli-
fied bv circuitry within the Quick Select pressure
3/99
module. The amplified output 15 then calibrated over
the operating range of the module. Calibration coeth-
cients for the module are stored in Electrically Erasable
Programmable Read Only Memory (EEPROM) within
the Quick Select pressure module.
GQS-2 modules are available in ranges from 5
through 10,000 ps:. These modules can be config-
ured to provide gauge, compound or absolute
pressure measurement, as well as vacuum measure-
ment capabilities. GQS-2 modules in ranges up to
300 psi are designed for use on clean, dry, noncorro-
sive and nonconductive gases. Optional 316 stainless
steel module isolation is available for ranges from 0/
10 through 0/300 psi. Ranges from 500 psi through
10.000 psi are provided with 316 stainless steel
isolation as standard.
Section 1.2.3 The GQS-RT Quick
Select RTD Interface Module
The GQS-RT1 allows the MC6 base unit, when used
with RTD temperature probes, to provide precision
temperature measurement data. The GQS-RT1 plugs
directly into the Quick Select module bay in the base
unit. Any standard RTD probe with a Switchcraft
TA4M connector can be plugged into the Switchcraft
TA4F connector on the module.
The GQS-RT1 module comes factory programmed
with the curves for Pt 100 (385 & 392), Cu 10 and
Ni 120 RTD probes. It supports RTDs with outputs
in the range of 0/400 ohms. The GQS-RT2 is sup-
plied factory programmed to support the Pt1000 (
385 & 392) RTD. This module will support RTDs
through an output up to 4000 ohms. The GQS-RT
module can be programmed with coefficients for
other RTD probes of interest and specific character-
istics of a probe alrcady included in the on-board
library can be programmed into the GQS-RT unit to
provide enhanced accuracy.
Each GQS-RT module can accommodate up to 8
different programmed RTD calibration curves.
Programming of the RT module is accomplished via
an optional software package (part number
838X014-01 for the 3 1/2 inch disk and 838X014-02
for the 5 1/4 inch disk) and any PC compatible
computer with an available standard serial communi-
cation port.

Section 1.4.4 The GQS-TC Quick Select
Thermocouple Interface
Module
The GQS-TC allows the HHC base unit, when used
with a thermocouple interface module, to perform
temperature measurement. The GQS-TC plugs
directly into the Quick Select module bay in the base
unit. The thermocouple is then attactched to the
GQS-TC module via a male “miniature thermo-
couple connector” (which is offered as an optional
accesory, see section 17.0).
Section 2.0 Unpacking & General Care
General instructions on unpacking and care follow.
Section 2.1 Unpacking Product Upon
Receipt
Prior to removing the MC6 Digital Indicator System
from the packaging material inspect all cartons for
shipping damage. Document any damage evident in
the event that a damage claim must be made against
the shipper. After inspection, remove the base unit,
module(s), manual and any accessories purchased
from the packaging material. Retain the packaging
for use in returning the MC6 to the factory for future
recertification or repair.
Section 2.2 Product Storage
The product should be stored in an area that 15
maintained in the temperature range indicated in the
storage temperature in the product specification. The
storage temperature limits arc -4 to + 158 degrees
Fahrenheit. Storage of product in environments that
will exceed these temperature limits results in
significant risk of product damage. It is recom-
mended that the product not be left in closed cars or
truck cabs as temperature damage can easily occur
due to the “greenhouse effect” of closed vehicles or
extreme cold temperatures that can result from
winter conditions.
Section 2.3 Product Cleaning

assembly. If only one Quick Select pressure module
is needed install the System Protection Module (part
number 875D114-02) supplied with your unit at the
time of shipment when using the MC6 system.
Section 3.4 Starting-Up the MC6 System
After the desired Quick Select pressure module(s) or
Quick Select temperature measurement interface
module and probe has been installed the MC6
System can be started up as follows with the unit
plugged in or with the optional nickel cadmium
batteries charged:
Turn the system power on by pressing the on/off key
on the instrument's key pad.
ON
OFF
During the start up process the MC6 will display a
series of start-up screens that:
* identify the type of module in each bay
* identify the range of each installed
module (ohms range for GOS-RT modules)
* indicate that the installed module (pressure
only) has been calibrated with enhanced
temperature performance. (consult
specification sheet for detail on this
capability)
Afier the start-up routine is complete the MC6 will
display: (for base with (wo pressure modules installed)
Range Range
xx EngUnit xx EngUnit
The range indication is provided in the primary
engineering unit for each installed Quick Select
module. Upon initial power up an MC6 base unit
used with an GQS-RT1 temperature module and
probe will default to displaying the ohms (resistance
value) for the probe. Once set up this combination
will default to the previously used temperature
measurement unit. such as Celsius, Fahrenheit,
Kelvin or Rankine. The primary engineering unit for
a given Quick Select pressure module, along with the
-12-
measurement range, is included on the module label.
The information on the left side of the display
corresponds with the Quick Select module installed
in the left module bay and information on right side
of the display corresponds with the Quick Select
module installed in the right module bay. If only onc
moduic is installed the corresponding side of the
display will indicate “no module” on power up.
After the third screen the MC6 system will com-
mence providing measurement data. The format for
display of the measurement data is as follows:
Eng Unit Eng Unit (primary engineering unit)
+хх.ххх +xx.xxx (measured value with sign)
When only one module is installed, the side of the
display corresponding to the side of the base unit that
does not have a module will display “- - - - - Ш
If necessary, the MC6 system, used with a Quick
Select pressure module, may be zeroed by pressing
the Zero key prior to beginning measurement
activities. Additional details on zeroing the MC6
system are provided in Section 6.0 of this manual.
The MC6 system is now ready for basic pressure or
temperature measurement. Simply connect the
pressure port(s) of the Quick Select pressure
module(s) to be used to the pressure source to be
measured. If a gauge pressure measurement is to be
made using a differential Quick Select pressure
module be sure to connect the pressure to be mea-
sured to the high pressure port on the Quick Select
pressure module. For temperature measurement,
connect the RTD probe to be used to the Switchcraft
connector on the interface module and proceed to
Section 16.1 for instructions on setting up the MC6
system for temperature measurement.
Optional System Start Up
Procedures
Section 3.5
There are additional set up operations that can be
performed to increase the overall capabilities of the
MC6 system; these include:
1- Auto off function to protect from inadvertently
leaving the MC6 system on and depleting
batteries in systems equipped with the nickel
cadmium or alkaline battery option.
2- Setting up battery level indication so that an
estimate of the remaining battery life can be
3/99
viewed at the push of a button. Alkaline only
see section 3.5.2 for details.
3- Programming the date and ume for use in date
stamping data logged measurements and for
initiating time delayed data logging on MC6
units with the optional data logging capability.
Current date and time information is only
maintained in units with the datalogging
option.
4- Programming owner/operator information for
display on the MC6 to facilitate tracking of
in-house instrumentation.
The following subsections provide information on
the above listed start up procedures.
Section 3.5.1 Auto Off- Battery Save
Function (BatSave)
The MC6 system can be set up to automatically turn
itself off if no keypad activity is detected for a 10
minute time period. This capability will protect MC6

“anrudequate power supply is available. The system, if
being operated off the nickel cadmium batteries, will
continue operation until the battery voltage is no
longer sufficient to power the system.
The battery save mode selected is stored in Electri-
cally Erasable Programmable Read Only Memory
(EEPROM). As such it does not require reprogram-
ming on power up.
Section 3.5.2 Battery Life of Optional
Battery Power Feature
The MC6 indicator 1s available with a choice of
built-in battery power options. These are:
|- Five AA alkaline batteries (non-rechargeable)

Section 3.5.3 Low Battery Icon
The MC6 System provides advanced warning of a
low battery condition. The low battery warning icon,
which looks like a miniature battery will flash in the
center of the top line of the display when tie mea-
sured battery voltage drops to 5.6 Vdc. The MC6
system will continue to function properly with the
low battery icon flashing.
To ensure uninterrupted measurement capability it is
recommended that the batteries be recharged
(NiCad) or replaced (alkaline) as soon as possible
after the low battery icon appears. When the mea-
sured voltage drops to 5.4 Vdc, the low battery icon
will flash on the display and the MC6 system will
turn itself off after 15 seconds. If the measured
voltage drops below 5.2 Vdc the MC6 system will
not allow power up.
Summary of low battery warnings:
5.6 Vdc: Low battery icon appears
5.4 Vdc: Low battery icon remains on
display, unit powers
down after 15 seconds.
5.2 Vdc: Power up not allowed
It is estimated that the user will have between 30 and
45 minutes of battery life remaining (without the
backlight option on) when the low battery icon
initially appears. Actual battery life remaining will
vary based on tasks being performed and ambient
operating temperature.
Section 3.5.4 Programming Date & Time

Temperature Selection for H O
Conversion Factor
Section 8.5
The MC6 system includes a library of 12 factory
programmed engineering units. This selection
includes the engineering units inH20, mmH20 and
cmH20. The pressure generated by a column of
water will vary with the temperature of the water.
Over the years, several temperatures references have
evolved into industry standards. These are the
conversion factors most commonly used by manu-
facturers of pressure instruments when calibrating
pressure measurement devices in terms of the height
of a column of water. To facilitate your calibration
and test of these instruments, the MC6 system
includes 3 conversion factors for each of the water
column based pressure engineering units. The
3/99
conversion factors are for the temperatures of 4 and
20 degrees Celsius and 60 degrees Fahrenheit.
The selection of the desired temperature for use in
the conversion of water based pressure measure-
ments can be accomplished by following these steps.
Step 1 With the MC6 system on and reading
pressure press the SET UP key.

After pressing the enter key the MC6 system will
resume basic pressure measurement.
Section 9.0 Tare Function
The MC6 system has the ability to tare (subtract an
operator selected value) from the displayed pressure
or temperature measurement value of either one or
two installed Quick Select modules. This 15 most
3/99
commonly required in applications where a pressure
pre-load. as in a weighing application. must be
subtracted from the displayed pressure
measurement.
If the MC6 system 15 in use with two Quick Select
modules. independent tare values can be entered for
cach of the module modules. If one of two installed
Quick Select modules has been deactivated, meaning
the measured values are not shown on the display.
the MC6 system will request a tare value only for the
active module. To input a tare value for one or two
Quick Select pressure modules follow the steps
below:
Step 1 With the MC6 system on and displaying
pressure measurement data press the tare key.
TARE
The MC6 system will respond by displaying the
following:

both the minimum and maximum pressure or tem-
perature values measured. The following procedure
will allow review of these values.
Step 1 To recall the minimum and maximum values
~ simply press the key labeled: - -

where:
maximum values are displayed on the top line and
+12345 represents the maximum value(s) measured. |
Minimum values are displayed on the bottom line
and -12345 represents the minimum value(s)
measured.
If two Quick Select modules are installed, the min/
max function recalls and displays the minimum and
maximum values for both modules simultancously.
Step 2 To clear the stored minimum and maximum
value press the clear entry key:

Pressing any key other than the CE key will maintain
the stored values in memory.
Pressing any key on the keypad will return the MCG
system to normal pressure measurement activities.
Section 12.0 Damping
Damping provides the ability to stabilize the dis-
played or transmitted pressure value by minimizing
the effects of low level transients and electronic
instability. Damping is most commonly used with -
3/99
Quick Select pressure modules to overcome the
effects of pressure pulsation and vibration transmit-
ted through the measurement media. The level of
damping is established in the set up menu. Activation
of the damping process 1s accomplished through a
dedicated key on the keypad.
Damping accomplishes the stabilization of the
pressure measurement value by producing an aver-
aged pressure value which is shown on the display
and available for transmission over the RS232
interface. When damping is not activated the MC6
system takes a new pressure value approximately
every 130 mS (7.5/per second on average) and
updates the display. If required, this same measure-
ment data is also transmitted via the RS232 inter-
face.
When damping is activated the value displayed and/
or transmitted is an average value. The average
consists of the average of from 1-16 consecutive
readings. The higher the number of readings aver-
aged the greater the stabilization effect of the damp-
ing. The number of consecutive readings averaged 15
programmable, allowing the damping function to be
tailored to the specific requirements of most any
application.
Section 12.1 Set Up of the Damping
Function
The following steps should be used to set up the
level of damping desired.
Step 1 With the MC6 system on and reading
pressure press the SET UP key.
SET
UP
Step 2 Using the arrow keys move through the set
up menu and select “Dampen” on the display of the
MC6 system . The word “Dampen” will flash on the
display when selected.
EvniTimr Dampen
Leak Rate Status
Step 3 With the word Dampen flashing press the
enter key.
ENT
Step 4 In response to the activation of the dampen-
ing set up menu the MC6 system will respond by
displaying the following:
fast <------- > slow
Where the left most position represents zero damp-
ing (averaging of 1) and the right most position
represents maximum damping (averaging of 16
readings). Starting from the left each movement of
the highlighted box to the right increases the number
of samples being averaged by one (1). By moving
the highlighted ficld to the left the level of damping
can be reduced.
The level of damping desired will likely vary from
application to application and module range to
module range. For best results, select the minimum
amount of damping necessary to provide a stable
display value. It is important to recognize that while
damping will stabilize the displayed and/or transmit-
ted value it will also slow down the response rate to
a true pressure change. The slow down results from
the fact that an averaged value will be displayed. If
the damping level is set to 16 the displayed value
will represent the average pressure measurement
over the previous approximately 2.1 seconds (16
readings times 130 mS/rcading). Therefore, the
greater the level of damping in use the greater the
time lag will be between the displayed measurement
and the true (not averaged) pressure measurement
value.
Note: Speed of update is based on display of a
single measurement parameter on one side of the
instrument display.
Use the left/right arrow keys to set the desired
damping level, for example, averaging 8 readings as
shown here.

process 1s activated.
Section 12.2 Activating or Discontinuing the
Damping Function
The following process provides step by step instruc-
tions on how to activate or discontinue the damping
function.

… . Section 13.0... Percent Function... . +.
The percent function allows the MC6 system to
display the output from a device under test in terms
of percent error.at a given percentage of the total
-- «range. This function applies to thie calibration of both
temperature and pressure transmitters. For example,
if the MC6 system is being used to calibrate a 0-100
psi transmitter with a 4/20 mA output the MC6
system can be programmed to display the following
data:
Pressure Normal
Applied Display Mode
0 psi 4 mA
0 psi 5.6 mA
25 psi 8 mA
50 psi 12 mA
75 psi 16 mA
100 psi 20 mA
The percent mode of operation allows for quick and
easy determination of the level of inaccuracy of the
device under calibration. For example: If 50 psi was
applied to a 100 psi device with a 0-10 Vdc output
but instead of 5 Vdc the transmitter being calibrated
had an output of 4.995 Vdc the MC6 system, when
uscd in the percent mode, displays the following:
% scale % crror
+50 -0.05
Therefore. tie percent made of operation eliminates
the need for operator calculations to determine the
level of accuracy of the device under test.
[f the MC6 system 1s equipped with the data logging
option the percent error and percent full scale
information can be stored in the MCO system on-
board memory. To do this follow the set up instruc-
tion provided in Section 21.5 Manual Data Logging.
Note: The MC6 system is available with an optional
24 Vdc built-in loop power supply. This supply can
be used to power transducers, transmitters and
switches during calibration and test operations. If the
MC6 indicator is to be powered by the battery
option, Section 3.2 of this manual should be con-
sulted tor the efiects of the loop power supply on
battery life.
Your calibrator supplier also offers an accessory for
use in calibrating transmitters and transducers
“designated the LPS-[a loop power supply. The
“Model LPS-Ila- is a portable 9 Vdc powered power
supply that provides a 24 Vdc output. This device
can also be used to provide the necessary electrical
supply to power transducers and transmitters for,
"infield calibration testing. For information contact

Section 14.0 Flow Velocity and Flow Volume
Mcasurement Background
The MC6 system used in conjunction with a pito
tube or an annubar has the ability of measuring the
flow volume or flow velocity of a gas. The MC6
system must be used in conjunction with an GOS-1
low differential pressure Quick Select module to
perform the flow measurement function.
The accuracy of a flow measurement is a function of
a number of contributing factors. These are; the basic
. ‘accuracy of the differential pressure measurement, |
accuracy of the pitot tube or annubar inuse as it
relates to the K factor supplicd by the manufacturer
of the device and the accuracy of the correction |
.. being made for the air. density. It is.not possible for...
your calibrator supplier personnel to provide an all
inclusive accuracy statement for flow measurement
activities. Steps that can be taken to maximize
system flow measurement accuracy include:
—. 4--Calculation and-input-of the actual airdensity for -:-
the media to be measured. The air density is a
function of temperature, humidity, barometric
pressure.
The velocity equation (ft/min) is as follow:
dpw
V=1097xK Adw
where:
dpw= differential pressure in inches of water
Adw= the air density
The air density can further be calculated through
employing the following equation:
A =0.07649 x ( Pa/14.73) x (520/(T+460)]
d
where:
Pa = the absolute pressure in duct in psia
T = air temperature in duct in degrees Fahrenheit
Flow Volume = (velocity x duct arca)/144

The MC6 system will respond by displaying:
Resolution:
1.1 .01 0.001
The maximum resolution that the combination of the
MC6 system base unit, RTD interface module and
probe can support can be determined as follows:
The resolution of the RTD module is 0.001% of the
full scale resistance of the reference resistor used in
the module. The GQS-RT1 incorporates a 400 ohm
reference resistor and the GQS-RT2 incorporates a
4000 ohm reference resistor.
Using the GOS-RT1 as the example the maximum
resolution 1s:
0.001% of 400 ohms
= 0.00001 x 400 = 0.004 ohms
For a Pt100 the temperature resolution can be deter-
mined as follows:
0.004 ohms/(100 ohms x 0.00385 ohms/degree C) =
0.008 degrees C (approx 0.005 degrees F)
Therefore, rounding to the next highest digit results
in a resolution of 0.01 degrees C.

Section 16.2 Calibrating/Programming
the GQS-RT RTD
Interface Module
The GQS-RT can be programmed in the field.
Programming, calibration adjustment or recertifica-
tion can be accomplished with the Calibration
Programming Utility disk part number 838X014-01
(3 % inch disk) or 838X014-02 (5 % inch disk).
Please note, in order to improve the accuracy of the
measurement system it will be necessary to generate
a significant number of very accurate temperature
calibration points using precision temperature baths.
In general, the simplest way to enhance the accuracy
of the temperature measurement is to simply re-zero
the probe while immersed in an ice bath.

Section 18.0 Pressure and Temperature
Switch Testing
The MC6 system can be used to test pressure and
temperature switches. On board firmware provides
the ability to verify switch trip points, reset point and
to test the deadband of a pressure switch. To perform
these type of tests follow the procedures as outlined
in the subsections of Section 17.
The switch testing process incorporated in the MC6
system firmware looks for a change of state that
produces a change of greater than either 2 volts or a
2 mA across the corresponding banana jacks. The
banana jacks are located on the bottom of the keypad
on the MC6 system. Prior to initiating these test
procedures the required clectrical set up should be
configured to provide the necessary signal levels,
Setting Up the MC6 system for
Testing of Pressure and
Temperature Switches
Section 18.1
en EN
The following procedure outlines the set up required
tor the test of pressure and temperature switches.
Step 1 With the MC6 system on and reading
pressure or temperature, in accordance with the type
of switch to be tested, press the Port Select key,
designated PORT SEL, the required number of times
to leave activated the Quick Select module being
used for the test function and deactivate (convert the
display to mA, “------ ” or Volts) the other side of
the display.
PORT
SEL
Step 2 Press the mA/V key as required to change
the electrical measurement parameter to that to be
used for the switch test. Switch to Volts if the change
of state will be greater than 2 Volts; switch to mA if
the change of state will be greater than 2 mA.
mA
V
Step 3 Connect the switch electronics with a current
or voltage source, as required, to provide the re-
quired greater than 2 Vdc or greater than 2 mA
change in state. Be certain that the change in state to
be generated corresponds to the electrical measure-
ment (mA or V) set up on the display of the MC6
system.
Notes: Your calibrator supplier provides several
accessories/options to simplify the testing of
switches. These are:
I- The MC6 system is available with an optional 24
Vdc built-in loop power supply. This supply can be
used to power transducers, transmitters and switches
during calibration and test operations. If the MC6
indicator 1s to be powered by the battery option,
Section 3.2 of this manual should be consulted for
the effects of the loop power supply on battery life.
2- Loop Power Supply, Model LPS-Ila- A portable 9
Vdc powered power supply that provides a 24 Vdc
output. This device can be used to provide the
necessary electrical supply for the testing of switches
that are not active or connected to a line supply. For
information contact your calibrator supplier and
request bulletin HACC-PS.
3- Voltage Converter. Model SM-1- A modular
voltage adapter device that connects to the voltage
and common banana jacks on the MC6 svstem. The
3/99 -4 | -
MC6 system voltage measurement capabilitv is
limited to 30 Vdc. Testing of switches used in
controlling higher level electrical supplies, without
first reducing the input to an acceptable level. could
seriously damage the MCG system electronics. The
SM-1 will reduce electrical inputs in the range of 10/
250 Vac and 10/400 Vdc to 3 Vdc. The 3 Vdc output
from the SM-1 will provide suflicient output (over 2
Vdc) to register as a change in state while also
protecting the MC6 system electronics from damage.
Step 4 Connect the output signal of the switch to
the banana jacks on the front of the MC6 system as
outlined below.
For voltage: volts (V) jack and common (COM).
For current: milliamps (mA) jack and common.

Important Note: Due to the extreme variation in
battery life under different operating conditions
(backlight on or off or loop supply in use, it is
recommended that the battery voltage value be used
to determine when replacement of batteries is
warranted.
Step 1 Install new batteries as outlined in the base

Note: Installation of new alkaline batteries will
produce an initial voltage measurement of 6.8-7.5
Volts on the MC6 system. If the value measured is
significantly below this level it is likely that the
batteries have degraded in storage and that they will
provide less than the 48 hours of operation expected
from a set of fresh. fully charged batteries.
Important Note: lt is recommended that batteries be
replaced or, in the case of NiCad batery pack useage
that the batteries be recharged when the low voltage

Section 21.0 Dual Module Functions
(Optional Built-in Firmware)
The MC6 system can be equipped with optional
firmware that can automatically add the measured
pressure values from two installed Quick Select
pressure modules or to subtract the value measured
by the Quick Select module installed in the right
module bay from the measured value of the Quick
Select value in the left module bay. This optional
firmware allows for the following:
1- The ability to subtract the measured value from the
left module of the measured value derived from the
right module allows for simplified measurement of
what are commonly referred to as “high-line” or
clevated static differential pressures. A complete
description of this capability is provided in Section
20.2 entitled Dual Module Differential Pressure
Measurement.
2- The ability to add the measured values of the two
installed Quick Select pressure module allows for the
addition of a measured barometric pressure from an
absolute pressure module to the measured pressure
from a gauge or differential pressure. This capability
can come in handy and save money by allowing
the use of gauge measurement Quick Select pressure
modules for absolute pressure measurement activities.
Accuracy of Dual Module
Measurements
Section 21.1
The accuracy of measurements made using the dual
module approach measurement is a function of the
full scale range of the Quick Select pressure modules
used and. in the case of differential pressure mea-
surements. the magnitude of the dp range.
For dual module summation measurements:
The worst case inaccuracy would be the sum of the
inaccuracies of the two Quick Select modules used
for the measurement. For example, if the measure-
ment is made with two +0.1% full scale modules the
maximum inaccuracy would be +0.2%. In actual use.
it is generally acceptable to use the Root Sum of the
Square (RSS) method of determining the accuracy of
a multiple component measurement system. Using
the RSS method the accuracy of the dual module
summation is approximately +0.14% of span.
For dual module differential
pressure measurement:
Fhe accuracy of the dual module differential pres-
sure measurement 1s a function of the full scale
range of the Quick Select modules used in the
measurement process and the magnitude of the dp
range. In general, the accuracy for the dp measure-
ment for dp ranges less than 10% of the rated range
of the Quick select modules used is +0.37% of dp
range +1 count. For dp ranges greater than 10% of
the range of the Quick Select pressure module
installed the accuracy of the dp measurement is
+0.37 % of the dp range +0.1(R 1) where R1 equals
the ratio of the module full scale to the dp full scale
(Sensor full scale/dp full scale). Easy reference
tables are included in the appendices of this manual
with pre-calculated accuracies for all dual module dp
measurement.
Section 21.2 Setting Up Dual Module
Differential Pressure
Measurement
Note: This is an optional capability. Only MC6
systems ordered with this option will be capable of
performing this function. This capability can be
added in the field by purchase and installation of a

capability.
Step 1 With the MC6 system off, install the two
Quick Select pressure modules in the MC6 base unit.
Be certain to install the module so that the modules
are in the desired module bays. The subtraction
process is always defined as the subtraction of the
measured value of the right module from that of the
measured value of the left module (d/p= Left mea-
surement

In some instances the ability to delete specific stored
data points can be useful. In particular, this can be
the case when data of questionable integrity has been
stored in the data log memory. The MC6 system
allows for the deletion of specific operator selected
stored data points. There are limitations to this
capability.
These limitations are as follows:
1) The remaining data will stay in the original
sequence with blank data fields left where
the stored data points have been deleted.
2) The MC6 system will not compress the data to
the new, smaller data set.
3) The newly erased fields cannot be used for the
storage of new data values until a
complete data erase has been done.

The tag name can be any combination of alphabeti-
cal or numeric entries. The maximum entries per tag
name is 16 characters.
The tag name is the key designation under which all
subsequent calibration for this calibration data set
will be organized. Tag names or tag numbers are
routinely identifiers assigned to measurement
instruments when put into service within a facility. If
no tag identifier is assigned to the device to be tested
it is recommended that one be created by combining
- some abbreviation for the manufacturer’s name and
the instrument serial number for the device to be
tested. The use of the “CertGen” firmware requires
the entry of a tag name for each device to be cali-
brated.
Use the up/down and left/right arrows to enter a tag

(uncorrected/unadjusted) calibration data. To collect
“as found” data press the enter key with the text
“AsFound” flashing on the display.
ENT
The calibrator will respond by prompting the opera-
tor to enter the number of “as found” data points to
be taken. A data point consists of the pressure
measurement as read on the calibrator and the
current or voltage output from the device under test
as measured on the calibrator. Therefore, each data
point is actually two (2) measurement values. The
prompt appears as follows.
Enter#of Testpts
.000000
The number of test points can be any value from | to
21.
Important Note: The calibrator can store sufficient
measurement data to calibrate 10 devices each with
10 “as found” and 10 “as left” data points (corre-
sponding to 200 test points. Each test point includes
both pressure/temperature and electrical measure-
ment data). In addition to storing the measurement
test data the heading or label information for each
calibration is also stored in memory. This informa-
tion includes: tag name, ambient temperature, “as
found” label, “as left” label and action taken.
Prior to initiating the calibration process the base
unit will prompt the operator with a screen providing
the remaining storage capacity for data in terms of
number of data points. If the operator enters a
number of test points that exceeds the available
memory the following message will be displayed:
Value exceeds #
remaining points
Pressing any key will return the prompt requesting
entry of the number of test points to be run. The
number of test points entered must be less than or
equal to the remaining test points available. Memory
requirement for the calibration heading information
arc already factored into the information provided
regarding the number of test points remaining. The
number displayed may be completely aliocated to
measurement data without worry about leaving space
for needed labelling.

Section 27.0 Recertification of the Calibrator
Both the base unit and the pressure modules can be
recalibrated and recertified in the field. The base unit
inciudcs a firmware based, menu driven procedure
that provides operator prompts to facilitate the
recalibration process. The procedure encompasses
both the acquisition of “as found™ data and perform-
ing adjustment and recalibration of the base unit and
modules. The recertification program is accessed via
the set up menu key.
-68-
Section 27.1 Access Codes
The calibration data is password protected with an
access code. The recalibration access code is
different than the owner access code. Both of the
access codes are provided with the calibrator at time
of shipment and are located on the base unit calibra-
tion certificate. If the access code has been lost
contact the factory and be prepared to provide the
serial number of the base unit. The serial number is
located on the product label on the underside of the
base unit.
Section 27.2 Calibration/Recertification
Overview
The base unit calibration firmware provides a means
of linearization and recertification of pressure
modules and the base unit's electrical input (Vde/
mA) calibration reference. In addition, the base unit
employs a precision 1 VDC reference for interfacing
with the modules which can be calibrated. The
calibration of this reference is critical to ensure the
combined output of pressure module and base unit is
within rated accuracy.The following equipment is
required to perform recalibration or recertification of
the calibrator.
Section 27.3 Required Equipment
|. A precision voltage supply capable of providing
| Vde + 50 microvolts
2. Primary pressure standard with an accuracy
rating of 4:1 compared to the rating of the pressure
module to be tested.
3. Test leads with banana jacks and mini clips.
4. Recommended - Model CQS calibration quick
select module. Although recalibration and recertifi-
cation work can be performed with out it, this
module will greatly simplify the process and reduce
risk of damage to the base unit.

Section 27.6 Recertification of Quick Select
Pressure Modules
The calibrator is available in a selection of accura-
cies trom £0.25% of span through £0.05% of span.
covering ranges from 0.25 inches of water to 10.000
psi. Whereas. the calibrator can be calibrated in the
field. appropriate pressure standards must be used to
assure the accuracy of the calibrator system Is not
degraded by the calibration process. As recom-
mended by standards organizations such as
A.S.M.E., N.LS.T and various U.S. and world
government agencies calibration standards should be
at least 4 times more accurate than the device to be
calibrated.
Therefore, if you will be calibrating a +0.!1% of span
Quick Select pressure module, a standard of equiva-
lent range would have to have an accuracy of at least
+0.025% of span. If the standard to be used is of a
higher range than the Quick Select pressure module
to be calibrated, even greater accuracy is required.
For example, if a +0.1% of span Quick Select
pressure module with a range of 50 psi is to be
calibrated with a 100 psi standard, the calibrating
standard should have a minimum accuracy of
+0.0125% of span. If you have any questions regard-
ing the recommended standards to calibrate Quick
Select Pressure Modules please contact:

as follows for calibration point of 10.002.
Apply and enter
value 10.002
Step 31 With the applied pressure displayed press the
enter key.
ENT
The calibrator will respond by displaying:
+XXXXX working
After 3-5 seconds the calibrator will request the next
calibration point by displaying.
Apply and enter
value 2.00000
Step 32 Apply the pressure required for the next
calibration point and enter the applied pressure value
with the number keys. For the second point a pres-
sure of 20.003 has been applied.
Apply and enter
value 20.003
Step 33 With the required pressure level applied and
shown on the display press the enter key.

Step 34 Repeat steps 23-26 as many times as re-
quired to produce the desired number of linearization
points.

A maximum of 18 linearization points plus the zero
and span points may be programmed for Quick
Select pressure modules. Factory calibration consists
of a 10 point linearization combined with a 10 point
upscale and 10 point down scale linearization and
hysteresis check.
Important Note: The number of calibration points
needed to assure adequate correction for non-
linearity is as follows:
Sensor Accuracy Number of Points
0.05% including temperature 20
(5% increments)
0.05-0.07% ||
(10% increments and zero)
0.1% 6
(20% increments and zero)
0.25% 5
(25% increments and zero)
Step 35 When the final linearization point to be
performed has been completed press the clear entry
key.
CE
The calibrator will respond by displaying:
Calibration done
Save Cancel
Step 36 To save the new linearization data to
memory, thereby overwriting the previously stored
values in the EEPROM, select “Save™ and press
enter. To discard the newly generated calibration
information select “Cancel” and press enter.
Step 37 If “cancel” is selected the calibrator will exit
the calibration mode. If the enter key is pressed with
the word “save” flashing the calibrator will prompt
entry of the date of the new calibration as follows:
mmddyy
Step 38 Using the number keys enter the current date
such as:
mmddyy
031196
For March (03), eleventh (11), 1996
Step 39 With the desired date entered and displayed.
press the enter key.
