MC2 Hardware
Pressure Modules
Internal Pressure Module
Internal Pressure Modules are available in models MC2-MF and
MC2-PE. One gauge type Internal Pressure Module may be installed
into the aforementioned models. They may also include an additional Barometric Pressure Module.
The connector for the gauge type Internal Pressure module is located in MC2’s upper panel.
The allowed pressure media for gauge type internal pressure modules is inert, non-toxic, non-explosive media. Use of pressure media classified as dangerous is prohibited.
For Beamex 60° cone connector: To avoid damaging the calibrator,
use hand tightening only when connecting the pressure measurement hose (max. torque 5 Nm, approx. 3.6 lbf ft). If the use of tools
is required to secure the connection, apply the counterforce with a
spanner on the connector body’s hexagonal part.
Remember to be cautious when working with pressure and pressure modules. See also chapters Safety on page 20 and Safety
Precautions and Warnings on page 20.
External Pressure Modules
MC2 has a connector for External Pressure Modules (EXTs). The
connector is located on the left side of MC2. External Pressure
Modules, supported by MC2, may be connected to all MC2 models.
MC2 automatically recognizes when an External Pressure Module
is connected or removed. More of pressure measurement in part B
of this manual.
Connectors on the Left Side of MC2
The left side of MC2 (front view) has four connectors as follows:
EXT
External Pressure Modules are discussed in chapter External
Pressure Modules on page 5 and in Part B of this manual.
OPTION
Reserved for future needs
USB
For computer connection (e.g. when updating the firmware).
POWER
Charger connector (Battery eliminator when using dry cells)
Warning!
There is no galvanic isolation between the connectors on the
left side as well as the internal pressure module connector.

General
Terminals
The lower part of the front panel has terminals for measuring, generating and simulating signals. The terminals available vary depending on model at hand.
ƒ
Model PE has terminals for measuring voltage, current
and frequency. It can also be used when counting pulses
or detecting the state of a switch.
ƒ
Models MF and TE have the following additional terminals: Thermocouple measurement and simulation, RTD
measurement and simulation, voltage, current, frequency and pulse generation.
Support for Table Top Use
The support gives you a good viewing angle when MC2 is placed
on a table top.
Memory
MC2 maintains data very much like personal computers. Data is
saved on a solid state memory that does not need any power to
maintain its state. Solid state memory is also shock proof. All available storage can be used for anything that requires it.
Display
MC2 has a backlit LCD display. The resolution of the display is
160 x 160 pixels.
The backlight is turned on or off by briefly pressing the power button. Pressing the button for a longer time shuts down MC2. More of
backlight settings in part C of this manual.
To tune the contrast of the display:

Numeric Keys
The Number keys are used when entering numbers in numeric fields
and letters in text fields (as in cellular phones). Pressing the +/- key
toggles the sign of the entered numeric value. In text fields, this key
contains a set of symbols and Greek letters. The Decimal key adds
the decimal point to the numeric value that is currently edited. In
text fields, this key contains additional symbols such as punctuation marks as well as super and subscript numbers.
Arrow Keys and Enter Key
The arrow keys are used when moving the cursor on the screen.
They also have several special functions in certain situations, e.g.
when tuning the contrast of the display. The Enter key both starts
and finishes the editing of all types of fields.
On/Off and Backlight Key
The On/Off key switches MC2 on and off. Press the On/Off key for
about half-a-second to switch on/off. This delayed function prevents
accidental on/off switching of MC2. When pressing the On/Off key
briefly, it toggles the back light of the display on and off.
7
General
Batteries
MC2 supports the use of both rechargeable batteries and alkaline
batteries. When using alkaline batteries, you need a Dry Battery
Cartridge. MC2 automatically detects the battery type.
The alkaline batteries to be used are:
- Type:
AA
- Cell Voltage:
1.5 V
- Amount: 4
The charger for rechargeable batteries operates in the following
environments:
- Voltage:
100 … 240 VAC,
- Frequency:
50/60 Hz
MC2 may be used while the Battery Pack is being charged. The
charger may also be used together with the Dry Battery Cartridge.
Then it acts as a Battery eliminator.
The maximum operating time without recharging varies depending
on the usage of the display back light. Also the usage of the 24V
transmitter supply affects the maximum operating time. Even with
constant maximum load, the standard rechargeable batteries should
last for 6 hours. A good average operating time is 12 hours.
If alkaline batteries are in use, the maximum operating time also
depends on the quality of the batteries. An average operating time
is approximately 4 hours.
Full batteries:
Empty batteries:
The upper left corner of MC2’s display shows a picture of a battery.
The whiter the picture is, the more acute is the need for recharging
(or changing of the alkaline batteries).
Notes.
MC2’s internal clock/calendar uses a small amount of power although the calibrator is switched off. Remember to check the capacity of the batteries from time to time although MC2 is not in use.
To avoid loss of date and time, change the batteries with the charger /
battery eliminator connected.

MC2 Hardware
About the Charger and the Charging Procedure
When charging the batteries the battery symbol and a plug symbol
alternates on the status bar. When charging is ready, only the plug
symbol is shown.
If MC2 is shut off and the charger is connected, a battery status bar
appears. After a while an estimate of the remaining charge time
appears below the battery status bar (see leftmost picture below).

C H A R G IN G R E A D Y
B a tte ry s ta tu s
E s tim a te d tim e le ft: 2 h 1 4 m in
The charging time depends on calibrator’s current consumption
(backlight, mA sourcing etc.). With no extra load, the charging time
is approx. 5 hours.
When charging while MC2 displays the charging window, MC2 beeps
when the batteries are fully charged. Then the display looks like
rightmost picture above.
Warnings!
USE ONLY THE CHARGER PROVIDED WITH THE CALIBRATOR.
The charger accepts input voltages from 100 to 240 VAC.
The charger should only be used indoors and the temperature
should not exceed 35 °C (95 °F).

General
Removing/Replacing the Batteries
To remove or replace the batteries, perform the following procedure:
1. Turn MC2 upside down (the display facing the table top) and
lift the support.
2. Unscrew the two screws holding the cover (see the picture
above).
3. Bend the clip holding the battery pack connector and gently
pull the connector out.
To replace the battery pack, click the connector of the new battery
pack on its place (noting the polarity) and put the battery pack in its
slot.

MC2 Firmware
MC2 Firmware
MC2’s firmware is saved in FLASH memory. Therefore it is relatively easy to update the firmware whenever a new version with
fresh capabilities is released. See Firmware Update on page 25
for more information on updating the firmware in your MC2.
General Description
The following chapters briefly describe each main function.
Startup Procedure
When starting MC2 the startup procedure ends up in a welcome
screen. From there it proceeds to Basic Mode and you are ready to
start using the calibrator.
A more comprehensive description of the Startup Procedure is in
the beginning of Part B of this manual.
Basic Mode and Higher Level Functions
In Basic Mode you can measure signals. There are two separately
configurable windows available.
All main functions of Basic Mode are described in part B of this
manual.

Safety Precautions and Warnings
MC2 calibrator is a precision calibration tool that should be used by
skilled people who have read and understood this User Guide.
Working with MC2 involves the usage of pressure and/or electrical
instruments. Be sure to know how to work with these instruments
and how to safely connect/disconnect pressure hoses as well as
electrical test leads clips, etc.
Use MC2 only if you are certain of that it can be used safely. Safe
use of MC2 is no longer possible if one or more of the following
cases are true:
•
•
•
•
When the case of MC2 is evidently damaged
When MC2 is not functioning as expected
After prolonged storage in unfavorable conditions
After serious damage during transport
Sometimes it is necessary to use a portable radio transceiver while
working with the calibrator. To prevent calibration errors caused by
the radio frequency interference, keep the radio far (at least 1 meter)
from the calibrator and the circuit under calibration while sending.
20
Safety
General Warnings
Do not use MC2 in any other way than as described in this User
Guide.
Use the MC2’s battery charger in a non-hazardous indoor location only and only with Beamex MC2 calibrators. While charging, the temperature should not exceed 35 °C (95 °F). If MC2’s
battery charger is broken, dispose it according to local waste
regulations and order a new charger from Beamex. Do not connect a broken charger to MC2.
MC2 uses a rechargeable Battery Pack or alkaline batteries. All
of these battery types are considered as hazardous waste. Dispose used batteries properly according to local regulations.
Avoid short circuiting the batteries. The short circuit current
may cause burns to you, damage to the device or even fire.
Notice, that also new replacement batteries are shipped in
charged state.
Rechargeable batteries may vent small amounts of gas during
recharge. The vented gas mixture may be highly explosive, but
normally it diffuses rapidly into the atmosphere. To avoid danger, use only the original charger and never recharge in a gastight container.
Warnings Concerning Electrical Measurement and Generation
The measurement and generation terminals of MC2 are protected against over voltage and over current as far as it has
been possible without affecting the accuracy. Do not however
connect signals that are above the measurement range of the
selected function.
There is no galvanic isolation between the connectors on the
left side, the internal pressure module connector and the terminals of the Temperature/Generate section.
Although there is a galvanic isolation between MC2’s Measure
and Temperature/Generate sections, it is for functional purposes
only. Do not exceed 60 VDC / 30 VAC / 100 mA between any
terminal.
Maximum output voltage from MC2’s terminals is below 30 V. If
you, however, connect together voltages from the Measure and
Temperature/Generate sections or if you connect external voltages to MC2, the resulting voltage may be high enough to be
hazardous.
21
General
General Warnings Concerning Pressure Measurement
The optional pressure T-hose is rated to the maximum pressure of 20 bar at 21°C (290 psi at 70°F). Applying higher pressure can be hazardous. We recommend the use of the optional
pressure hose set. When using other hoses and connectors,
make sure they are high quality products that withstand the
used pressure.
To avoid damaging the calibrator, use hand tightening only
(max. torque 5 Nm) when connecting the pressure measurement hose to the internal pressure module. If the use of tools
is required to secure the connection (typically an internal pressure module with a pressure range of 20 bar / 300 psi), apply
the counterforce with a spanner on the connector body’s hexagonal part.
Always depressurize the system before opening or connecting
any pressure fittings or connectors. Use proper valves for venting the system. Ensure that all connections are made correctly
and that the hose and the connectors are intact.
The allowed pressure media for internal pressure modules is
inert, non- toxic, non-explosive media. External modules have
the allowed media printed on the module’s sticker. Using unsuitable pressure media may destroy the pressure module/calibrator.
Never exceed the maximum pressure of a pressure module.
The internal pressure module’s maximum pressure is stated
on calibrator’s sticker. The maximum pressure of external
modules is stated on module’s sticker and mentioned in the
Instruction Leaflet that is provided with the external module.
Never plug a hose with your hands or put hands in front of a
gas spray coming from a leakage. A gas bubble in the blood
circulation can cause death.
22
Safety
Warnings Concerning High Pressure
High pressure is always dangerous. Only personnel with good
experience and knowledge of high pressure liquid, air and nitrogen operations are allowed to work with the module. Read
carefully all these instructions and local safety instructions for
high pressure operations before starting the use.
When using gas, the system must not contain any liquid, especially if you do not know how they may react under pressure.
Use of clean air or nitrogen is recommended as gaseous pressure media. Liquid pressure media should be preferred when
using modules with a pressure range of 60 bar (30000 psi) or
more.
If you use nitrogen, minimize the leak to the atmosphere and
take care of sufficient ventilation. Close the valve of the nitrogen cylinder, when the system is not in use. Increase in the
percentage of nitrogen in the ambient air may cause unconsciousness and death without warning. Read carefully the
safety instructions for nitrogen and make sure that the other
people in the same space are aware of the danger.
Use of liquid pressure medium is recommended with pressure
measurement modules at higher pressure range. Use water or
suitable hydraulic oil. Check that the used liquid is not aggressive against the materials used in the transducer or tubing.
When using liquid, minimize the amount of air in the system.
So you can minimize the amount of spilled liquid in case of
leakage.
Do not use the same tubing with different liquids or gases.
Check what the local regulations say about construction and
use of pressurized vessels. The regulations normally control
construction and use of systems where the product of the pressure and volume exceeds a certain limit. The volume of this
system depends on the instrument connected to it.
High pressure gas is dangerous because it can break the container and the flying splinters may cause injury. Also small leaks
of gas may be dangerous because the high velocity of the leaking gas jet enables penetration through skin. If a gas bubble
gets into the blood circulation, it can cause death. The leak jet
is particularly penetrative, if some liquid is coming with the
gas.

Measuring
Connecting and Disconnecting External Pressure Modules
An external pressure module may be connected and disconnected
at any time. If a removed module was part of an active measurement, MC2 emits a “bleep” to inform you of the fact that the external
pressure module used for pressure measurement was removed.
The window where the external pressure measurement was configured reverts to “None/No Function”. This happens even if the eternal pressure module was used as the secondary measurement in a
special measurement.
External Barometric Module Specifics
If MC2 includes an internal barometric pressure module and an
external barometric module is connected, the following rules apply:
ƒ
ƒ
ƒ
For most cases: When the external barometric module
is connected to MC2, it supersedes the internal barometric module.
Exception: If the internal barometric module is used in
conjunction with a gauge module (Pressure Type is Absolute) and the external barometric module is connected,
then MC2 continues to use the internal barometric during that measurement session.
Disconnecting: When the external barometric module
is removed, any measurements utilizing it are stopped.
Restarting the measurement takes the (possible) internal barometric module in use.
Zeroing a Pressure Module
If the selected pressure module does not display zero gauge pressure when the applied pressure is zero, the module has to be zeroed.
Open the appropriate window setup menu ( F1 / Setup n or
F2/Setup o) and select F1/Zero Pressure. If a secondary pressure module is active in the selected window (see Tools Menu on
page 57), a pop-up menu will appear for choosing either to zero the
primary or the secondary pressure module.
NOTE!
Zeroing a pressure module is especially important when the
operating position of MC2 is changed or the location of MC2 is
changed in the vertical direction. Both of the above mentioned
factors affect notably on the pressure measurement modules.
Measuring pressure below 100 mbar (approx. 40 iwc) should
be done with a firmly mounted MC2 (e.g. placed on a table top).

The two leftmost terminals are used in 2-wire systems. MC2 automatically checks the connection and displays the found wiring system (2-wire, 3-wire or 4-wire) in the upper right corner of the measuring window. For more information concerning wiring options, see
Resistance and RTD Measurement, Connections on page 100.
Note.
If the measured resistance value is infinite or very high (> 4000
ohm), the text “+OVER” is displayed in the measuring window. This
means that the circuit is broken or the connection is wrong. Wrong
connection may also cause erroneous reading, typically too low. If
necessary, use the 2-wire ohm measurement to check the wiring
before final connection.

Switch State Sensing
MC2 is capable of detecting switch’s state both when the switch is
free of external potential or switches with DC voltages within the
range -1 V to +30 V. See the pictures below for the location of the
active terminals, depending on the model at hand.
Function:
Switch
Also check the Trigger Level setting. There you can specify whether
to use only a trigger voltage level or do you also want MC2 to include a test voltage to detect switches with no external potential. All
voltages below the trigger level are treated as a closed contact and
all voltages above the trigger level are treated as an open contact.
M C 2 -M F &
M C 2 -T E
When switch state sensing is selected, the extra row info of the
window with the switch function is
capturing measurement values of
the other window every time the
switch changes its state. In the
adjoining screen shot, the switch’s
current state is “open” (the big
switch symbol). The last time the
switch opened, the pressure was
3.058 bar and the last time the
switch closed, the pressure was
1.983 bar.

Notes.
The accuracy of the captured values depend greatly on the change
rate of the switch’s input signal.
Hint!
Switch state detection may also be used for binary signal detection.
An open switch equals “1” or true” and a closed switch equals “0”
or “false”.
Use Switch Sound field to assign an “alarm” to a switch. Then you
can use switch test for conductivity/continuity tests with no need to
look at the display.
You can invert the switch’s open/closed state indication using the
check box available in the measurement window’s setup window.
This can be used to show real switch state when switch state sensing is connected to relay coil instead of relay contacts.

If the measured resistance value is infinite or very high (> 4000
ohm), the text “+OVER” is displayed in the measuring window. This
means that the circuit is broken or the connection is wrong. Wrong
connection may also cause erroneous reading, typically too low. If
necessary, use the 2-wire ohm measurement to check the wiring
before final connection.

MC2-MF and MC2-TE are capable of thermocouple temperature
measurement..
Function:
T/C Sensor Measurement
Make sure a temperature unit is selected from the Unit list. Otherwise the measurement displays voltages, not temperatures.
Check the Sensor setting. Make sure you select the same sensor
type than what is connected to MC2. Otherwise your measurement
results are unreliable.
Also select a suitable Reference Junction compensation method
from the RJ Mode list. Wrong reference junction setting results in
useless measurement results. Additional information about Reference Junction compensation methods can be found in chapters
Internal Reference Junction on
page 96 and External Reference
Junction on page 97.
The adjacent picture displays the
active terminals:
M C 2 -M F &
M C 2 -T E
By default the additional info row at
the bottom of the window displays
either the thermovoltage corresponding to Reference Junction
temperature 0°C (when Unit field is
set to temperature) or the thermovoltage with Reference Junction
compensation taken into account (when Unit field is set to “Voltage
+ RJ”). In both cases also the Reference Junction temperature is
shown. More of additional info row on page 79.
Warning!
If you connect an RTD sensor to the RTD connectors, there is
no galvanic isolation between the thermocouple and the RTD
sensor.

Warnings!
Make sure that you don’t exceed the maximum current allowed
by the instrument under test.
If you open the current generation loop, MC2 tries to maintain
the current by increasing the output voltage. If you then close
the loop again, the current is first too high, but returns quickly
to the correct level. If this current peak could damage the components of the loop, make sure that the loop will not open or
protect it against overcurrent. For the same reason, always enter
0 mA output before connecting the loop.

Notes.
In resistance simulation MC2 monitors the resistance measurement
current. If the current is too high, it cannot simulate the right resistance value. In that case it shows the message “High Cur”.
Accurate operation of the simulation electronics requires that the
current supplied by the instrument under test does not vary rapidly.
The simulation result is not accurate if the instrument under test
uses AC current. If the instrument under test uses pulsed measurement current, it should wait a few milliseconds before starting the
measurement after setting the current.

Thermocouple Simulation
In thermocouple simulation the original thermocouple is disconnected from the instrument under test and replaced with MC2. MC2
mimics a thermocouple at given temperatures. To the instrument
under test MC2 appears as a thermocouple at the given temperature. MC2-MF and MC2-TE are capable of thermocouple simulation.
Function:
T/C Sensor Simulation
Check the Sensor setting. Make sure you select the same sensor
type than what is required by the instrument under test. Otherwise
your measurement results are unreliable.
Also select a suitable Reference Junction compensation method
from the RJ Mode list. Wrong reference junction setting results in
useless measurement results. Additional information about Reference Junction compensation methods can be found in chapters
Internal Reference Junction on page 96 and
External Reference Junction on page 97.
The adjacent picture displays the active terminals:
By default the additional info row at
M C 2 -M F &
the bottom of the window displays
M C 2 -T E
either the thermovoltage corresponding to Reference Junction
temperature 0°C (when Unit field is
set to temperature) or the
thermovoltage with Reference Junction compensation taken into account (when Unit field is set to “Voltage + RJ”). In both cases also
the Reference Junction temperature is shown. More of additional
info row on page 82.
Notes.
If the resistance of the external circuit in thermocouple simulation is
very low (obvious short circuit), the message “Overload” is displayed
until the load is reasonable.
If the thermocouple to be simulated is not available MC2’s sensor
list, select one of the “Voltage + Reference Junction” units and convert from temperature to millivolts manually. Also select a thermocouple type from the Sensor list that approximately matches your
sensor (in used Reference Junction range). This allows MC2 to
perform Reference Junction compensation as accurately as pos54
Generating/Simulating
sible. In this situation, the accuracy depends on the similarity of the
selected sensor in MC2 and the used sensor.
Wire-wound thermocouple temperature indicators and recorders are calibrated with known loop resistance, commonly ten or
twenty ohms. The required resistance of the conductors is usually
marked on the device. When calibrating such a device, tune the
loop resistance to the nominal value with an additional resistor.
Use MC2’s 2-wire resistance measurement to tune the loop resistance of a wire wound device. Short circuit the measuring device
for the time of resistance measurement. The resistance measurement may damage the device, if you do not install the short circuit.
For more information on resistance measurement, see chapter
Resistance Measurement on page 38.
Warnings!
If you short circuit the thermocouple simulation output, MC2
tries to maintain the voltage by increasing the output current.
If you then open the output again, the voltage is first too high,
but returns quickly to the correct level. If this voltage peak could
damage the components of the circuit, make sure that the circuit can not be shorted or protect the circuit against overvoltage. For the same reason, always enter 0°C output before connecting the circuit.
If you connect an RTD sensor to the R, RTD connectors, there
is no galvanic isolation between the thermocouple and the RTD
sensor.

Tools Menu
Alarms
Each main measurement in a window may have alarm limits settings. MC2 supports “higher than”, “lower than”, “high rate” and “low
rate” alarms.
To set the alarm limits, enter the following menu commands:
F1/Setup n or F2/Setup o (depending on which window you want
to configure alarms to), F2/Tools and Alarms from the opened
menu.
Make sure the Alarms Active field is checked. Then the other settings are available. Table of alarm symbols used:
High alarm limit
Low alarm limit
High change rate alarm limit
Low change rate alarm limit
Individual alarm limit values may also be activated/deactivated using the check box preceding the alarm limit value. The alarms chosen for use are shown in the measurement window using the same
symbols as in the table above.
When an alarm limit is exceeded, MC2 emits an audible alarm and
the alarm symbol is shown with inverted colors. To acknowledge
the alarm, open the window’s setup window and from here the Tools
menu. Just below the menu’s Alarm option is an item that is shown
only when alarms are activated: Acknowledge this Alarm. The active alarm limit is inverted in the measurement window as long as
the alarm limit is exceeded.
Note.
Rate alarm limits are not “symmetrical”. E.g. high rate alarm 0.5 bar/
min emits an alarm when the pressure increases faster that the
limit but does not emit an alarm when the pressure decreases faster
than -0.5 bar/min.
59
Startup and Basic Operation
Hint.
If you want to set an alarm that utilizes the change rate alarm limit
but don’t know which limit value to use, display the change rate on
the additional info row (see chapter Display Mode and Special
Measurements on page 70). Observe what happens to the change
rate during the event that need an alarm. Then set the change rate
alarm limit accordingly.
Acknowledging Alarms
When an alarm is active, the Tools menu of the window with the
active alarm includes an option to acknowledge alarms.
Resetting Alarms and Alarm Limits
To stop using alarm limits, uncheck the Alarms Active field.
To stop using and clear all alarm limits, select another function or
reselect the same function.
Damping
Damping is useful when a measurement signal contains unwanted
noise. MC2 includes a set of damping tools.
Average filter the data using the average of recent measurements.
Adaptive average uses the measurement’s change rate to choose
the amount of recent measurements used in the average calculation.
The next group of options are 1st order digital filters with a damping
time as stated in their names.
To set the damping value, enter the following menu commands:
F1/Setup n or F2/Setup o (depending on which window you want
to configure damping to), F2/Tools and Damping from the opened
menu. The damping settings apply to all main and secondary measurements active in the window when damping was started.

To start the leak test, first check the test time to be used. Either
accept the default value or enter another time period in seconds.
Entering zero as the test time means the test will continue until
manually stopped. Select F3/Start and see how the test advances.
The rightmost picture on the previous page is an example of an
MC2 display during a leak test. The absolute decrease is shown
beside the triangle and the average decrease per minute below.
61
Startup and Basic Operation
Notes.
You may increase the test time in 30 second steps using the
F2/+30 s Function Key. This can be done both before the test is
started and also while the test is in progress.
MC2 uses numbers that have more decimals than are available on
the display. In some cases these extra digits may cause rounding
that differs from values that are shown on display. Notable differences between shown and manually calculated values usually mean
that MC2’s accuracy is not suitable for the given task.
Check/disable MC2’s auto-off functionality during the leak test. If
the leak test lasts longer than the auto-off delay, MC2 is shut down
while the leak test is still incomplete.
Hint.
If you have a pressure transmitter connected to a pressure measurement system and a you want to check the pressure decrease
without altering the pressure connections, do as follows:
Connect the output of the pressure transmitter to MC2. Use MC2’s
scaling utility to scale the output signal back to pressure units. Start
the leak test for the scaled measurement and there you can see the
leak in pressure units. More info on scaling in chapter Scaling on
page 75.

reading is not the actual measured value. Depending on the selected Display Mode or Special Measurement, some additional text
is also shown.
All Display Mode and Special Measurement settings revert to Normal display mode if you select another quantity. Additionally, the
same menu were a Display Mode or a Special Measurement was
invoked also includes a possibility to revert back to Normal Display Mode.
Note applying to all display modes and special measurements.
While performing display mode and/or special measurement calculations, MC2 uses numbers that have more decimals than are
available on the display. In some cases these extra digits may cause
rounding that differs from values that are shown on display. Notable
differences between shown and manually calculated values usually mean that MC2’s accuracy is not suitable for the given task.

Related Information
Related Information
Most of the measurements, generations and simulations presented
in this manual are straight forward: Just make the required window
settings and connect the instrument under test to the active terminals and that’s it!
Some cases require additional settings and things to check before
you can be certain that the measurement, generation or simulation
works as expected. A typical example of this is temperature measurement using a thermocouple. It is not enough to select the correct function in MC2. The Sensor type and the Reference Junction
Mode has to be set accordingly, too. Wrong settings give erroneous results.
Whenever this additional information may be of use in a measurement, generation or simulation, text describing the function refers
to one of the following chapters. An experienced may skip this
supplemental text, but for a beginner we highly recommend it.

Things to Consider when Measuring Pressure
General
MC2 can measure pressure with its internal pressure module or
with external pressure modules. If a barometric module is present,
the measurement results of other modules can be shown either as
absolute pressure or as gauge pressure.
Pressure Type
Every pressure measurement is in fact a pressure difference measurement: a given pressure value is compared against a reference
pressure. In certain cases the reference pressure has a special meaning (like the atmospheric pressure) and the pressure measurements
with reference to against these points are given a special name:
•
•
•
•
Absolute pressure measurement uses vacuum as the reference pressure.
Barometric pressure (or atmospheric pressure) is the absolute pressure of the surrounding atmosphere. It is specially
titled because of its importance.
Gauge pressure measurement uses the atmospheric pressure as the reference. Gauge pressure may be zero, negative
or positive. Most of MC2’s pressure modules actually measure gauge pressure although they may be used for measuring other pressure types too.
Differential pressure measurement requires a special differential pressure module that has an input available for both
the reference pressure and the given pressure.
To be able to measure absolute pressure with MC2’s gauge pressure modules, you need a barometric pressure module. Certain
high pressure modules may approximate absolute pressure measurement by adding an entered barometric pressure to the measured gauge pressure.
MC2 may use two standard pressure modules to measure (pseudo)
differential pressure: One module measures the reference pressure and another the given pressure. The pressure difference is
calculated by subtracting the reference pressure from the given
pressure. More of this in Part B, chapter Display Mode and Special Measurements.
Always ensure that the pressure type setting of your pressure
measurement is what you intended it to be. The pressure type
setting is crucial for getting meaningful pressure measurement
results.
94
Related Information
Pressure Modules and their Naming Conventions
MC2’s software refer to pressure modules as follows:
IPM200mC
which means that there is an internal pressure module installed
with a -200 to +200 mbar (-3 to +3 psi) pressure range.
The names of MC2’s internal pressure modules start with the letters IPM. The names also include numbers and possible additional
letters as follows:
1. The number defines the max. nominal pressure in the SI pressure unit bar.
2. If the number is followed by a small “m”, the given max. nominal pressure is given in mbar.
3. The additional letter C means the pressure module is a compound module with an ability to also measure negative gauge
pressures.
Examples: Name
IPM200mC
IPM20C
IPM160
Max. nominal pressure
in psi
±200 mbar
-1 … 20 bar
0 … 160 bar
±3
-14.5 … 300
0 … 2400
Notes.
Compound modules with a max. nominal pressure above 1 bar (e.g.
IPM20C) are able to measure negative pressures down to -1 bar.
Compound modules with a max. nominal pressure below 1 bar (e.g.
IPM200mC) are only able to measure as deep negative pressures
as positive pressures.
External pressure modules have a naming convention that is similar to internal ones.
Square Rooting
Pressure transmitters or converters used for flow measurement often have square rooting character. Here are a couple of examples
on how you can configure MC2 to take into account the instrument’s
square rooting character:
1. Set the Display Mode of window that measures the instrument’s
output signal to Error Percentage and make sure the Trans√x).
fer Function field is set to Square Rooting (√
2. Use Scaling to convert the instrument’s output signal to a suitable format and again, make sure the Transfer Function field
√x).
is set to Square Rooting (√
Display Modes as well as scaling is discussed in chapter Tools
Menu in part B of this User Guide.

Thermocouple Measurement/Simulation, Connections and
Troubleshooting
To accurately measure the thermovoltage caused by the temperature to be measured, the second thermovoltage caused by the Reference Junction needs to be compensated. This is done using one
of the Reference Junction compensation methods described in the
subsequent chapters.
The Reference Junction compensation method has to be chosen
both when measuring and simulating thermocouples.
Internal Reference Junction
MC2’s Internal Reference Junction makes
thermocouple measurement/simulation
easy. No external connections are required,
just connect the thermocouple or a
thermovoltage receiver directly to MC2’s
“T/C” terminals. To select this compensation method, set the window’s Function to
field “T/C Sensor Measurement” or “T/C
Sensor Simulation”, make sure the Unit
is a temperature unit and set the RJ Mode
field to “Internal”.

Advanced Operation and Configurations
Resistance and RTD Measurement, Connections
The two main problems in resistance and RTD measurement are
the effects of wiring resistances and thermovoltages in the resistance measurement circuit. If possible, use 4-wire connection to
eliminate the effect of wiring resistance. The special resistance
measurement sequence of MC2 eliminates the thermovoltages of
the resistance measurement circuit.
MC2 continuously checks the connection type during resistance
and RTD measurement. The found connection type is displayed on
the resistance or RTD measurement window.
4-wire System
3-wire System
MC2 sources current through the resistor
from the two left side terminals. MC2 measures the voltage drop across the resistor
from the two right side terminals. The 4wire method gives the resistance between
the terminals of the resistor, it is insensitive to the resistance of the connection
wires.
MC2 sources current through the resistor
from the two left side terminals. MC2 measures the voltage drop across the entire
current loop and across the low side connection wire. If both left side connection
wires are identical, MC2 can compensate
for the resistance of the connection wires.

When the compensation loop wiring system is used, MC2 displays the text “3-wire”.
Hint!
To minimize the effect of connection wires, use deviation measurement presented on page page 76 as follows:
Measure the resistance of only the connection wires. Set the measured value as the Measure Deviaton from value. Then the resistance of the connection wires is subtracted from the total resistance
and the displayed deviation value is closer to the resistance meant
to be measured.

Parallel Functions in MC2
This chapter explains what kind of simultaneous duties MC2 can
do.
All of the following tasks may run independently, but the window
settings decide what is shown:
ƒ
One measurement in the measurement terminals.
Electrical Measurement terminals in MC2-PE and
Measure terminals in MC2-TE and MC2-MF.
ƒ
Either one measurement or one generation/simulation in
the Temperature/Generate terminals of MC2-TE and
MC2-MF.
Also: During thermocouple measurement/simulation the
RTD terminals may be used for measuring the reference
junction temperature (RJ Mode field set to External
RTD).
ƒ
The internal pressure module(s) measuring pressure.
ƒ
A connected external pressure module measuring pressure.
Additionally, all of the connectors on the left side of MC2 may have
an independent task.
Note.
The Barometric module can always be used for pressure type conversion, even if it is already active in any window.

Adjustment
If the found error is outside acceptable limits (reject limits), the instrument needs adjustment. Activate one of MC2’s error display
modes to help you minimize the error (see Tools Menu in part B).
Use the instrument’s ZERO adjustment at lower end of the range.
Adjust the higher end of the range with the instrument’s SPAN adjustment. The two adjustment points do not necessarily need to be
the end points of the instrument range. You may want to use other
points to optimize the calibration at the most important part of the
range. Note, however, that if the points are very close to each other,
the error at other points of the range may be quite big (see As Left
Calibration on next page).

The pictures above display different As Left calibration graphs after
two different kinds of adjustments.
In the leftmost picture, the error is minimized at the end points of
the instrument range. This results in a relatively notable error in the
middle of the span. If the middle of the span is the area, where the
measurement is usually situated, then this method is not recommended.
The rightmost picture displays the error graph when the maximum
error is minimized by “lowering the graph”. As a result, the error
minimum is at approx. 30 % and 70 % of the span.
Note that these adjustment strategies are just examples. There is
an unlimited amount of “correct” ways to adjust an instrument.

The picture above is an example where a pressure transmitter is
calibrated using error percentage display mode for the output current. The additional info row displays the actual output current of
the instrument. Another useful method, especially while adjusting
the instrument, is displaying the error bar graph in the additional
info row.
A typical calibration procedure using MC2 is as follows:
1. Make the required connections, configure MC2’s windows to
suit the needs of the instrument
2. Test the instrument, connections and calibrator settings by altering the instrument’s input signal.
3. Start the calibration run by setting the instrument’s input signal
to a level needed for the first calibration point. Record the input and output signals and also the error value, if applicable.
Advance to next calibration point.
4. When all points are done, do another repeat if needed or if
adjust the instrument, if that is required.
5. When all repeats/adjustments are done, the calibration is ready.

Examples of Instrument Calibration
The following pages contain a few examples of how to calibrate an
instrument using MC2.
When uncertain, consult Part B of this manual for information on
how to connect instruments and configure the windows of MC2 to
suit the instrument’s needs.
The following calibration examples are presented in this manual:
Pressure Transmitters on page 112,
Temperature Indicators and Recorders on page 114,
Electrical Limit Switches on page 116,
Temperature Sensors on page 118 and
Pneumatic Pressure Transmitters and Converters on page 120.
Warning!
Working with pressure instruments can be hazardous. Only
qualified personnel may use pressure instruments and pressure sources. See pressure measurement related warnings in
Part A of this manual.
111
Calibration
Pressure Transmitters
This procedure suits all instruments with a pressure input and any
kind of electrical output signal. Both the input and output signal
range should be measurable with MC2.
All MC2 models (MC2-TE equipped with an external pressure module) are capable of calibrating a pressure transmitter.
Preparations
1. Connect the instrument’s input to the selected pressure module (internal or external).
2. Connect the pressure source both to the instrument’s input
and to the pressure module.
3. Connect the instrument’s output signal to the terminals in MC2.
4. Configure one of MC2’s windows to measure pressure and
the other to measure the electrical output signal of the instrument. If the output signal is current, select whether MC2 provides the supply voltage or not (see Current Measurement in
Part B).
5. Test the connections.

1. Set the pressure using, e.g. a pressure pump.
2. Record the input and output signals and also the error value, if
applicable.
3. Proceed to next calibration point (step 1) if applicable.
4. Continue by either adjusting the instrument, starting another
calibration repeat or ending the calibration.
Hint!
These instructions can be can be adapted for any kind of transmitters. Change the input signal connections/settings according to the
instruments input signal.
When calibrating another kind of pressure instrument, use this example as the source for the input signal part.
113
Calibration
Temperature Indicators and Recorders
This procedure suits temperature indicators/recorders no matter if
the sensor is an RTD or a thermocouple. The instruments input
signal is simulated using MC2.
MC2-TE and MC2-MF models are capable of calibrating temperature indicators and recorders.
Preparations
1. Connect suitable terminals in MC2 to the input connectors of
the indicator/recorder.
2. If the sensor to be simulated is a thermocouple, select one of
the following reference junction methods:
•
•
•
•
MC2’s internal reference junction is used.
The reference junction temperature is measured externally using an RTD connected to the RTD terminals.
The reference junction temperature is fixed to 0°C.
The reference junction temperature is manually entered.
Additional information about Reference Junction
compensation methods can be found in chapters
Internal Reference Junction on page 96 and
External Reference Junction on page 97.
3. If the sensor to be simulated is an RTD, the used wiring system depends on the instrument to be calibrated. Remember to
only use the two leftmost RTD terminals in MC2.
4. Configure one of MC2’s windows to simulate temperature
(T/C Sensor Simulation or
RTD Sensor Simulation). Test
the connections.
114
Calibrating an Instrument
Calibration
1. Enter the temperature to be simulated There are two different
strategies on how to set the temperature:
ƒ
Adjust the simulated value until the reading of the indicator/recorder is exactly the same as the default output
value for the current calibration point. This method is
useful when calibrating analog indicators/recorders and
the input signal can be fine adjusted.
ƒ
Do not adjust the simulated value, just use the actual
reading. This method suits indicators with digital display.
It is also handy when calibrating other types of indicators/recorders requiring an input signal not supporting
fine adjustment (e.g. pressure indicators).
2. Record the input signal and output reading/display.
3. Proceed to next calibration point (step 1) if applicable.
4. Continue by either adjusting the instrument, starting another
calibration repeat or ending the calibration.
Hint!
These instructions can be can be adapted for any kind of indicators/recorders. Change the input signal connections/settings according to the instruments input signal.
When calibrating a temperature instrument with a detachable sensor (the input signal is simulated with MC2), use this example as
the source for the input signal part.
115
Calibration
Electrical Limit Switches
This procedure suits limit switches with an electrical input. MC2
generates the switch's input signal and measures the switch's state.
MC2-TE and MC2-MF models are capable of calibrating electrical
limit switches.
Preparations
1. Connect the instrument’s input to MC2’s output terminals (see
picture).
2. Connect the switch’s output to the measuring terminals in MC2.
3. Configure one of MC2’s windows to generate the electrical signal and the other to measure the switch’s output.
4. Test the connections.
116
Calibrating an Instrument
Calibration
1. Slowly increase the instrument’s input signal until the switch
actuates. See part B for help on how to change the generated
value. The extra info row of the window configured to measure
the switch’s state displays the actuation point.
2. Continue by decreasing the input signal until the switch
deactuates. The deactuation point is also displayed on the extra
info row.
3. Record the actuation and the deactuation point.
4. Redo the test (step 1) if applicable.
5. Continue by either adjusting the instrument, starting another
calibration repeat or ending the calibration.
Note.
The slower you raise the input signal, the more accurate the observed actuation point is. Be equally careful when decreasing the
input signal in order to get as accurate deactuation point as possible.
Hint!
These instructions can be can be adapted for any kind of switches.
Change the input signal connections/settings according to the instruments input signal.
When calibrating an electrical instrument and the input signal is
generated with MC2, use this example as the source for the input
signal part.
117
Calibration
Temperature Sensors
This procedure suits temperature sensors no matter if they are RTDs
or thermocouples. The sensor’s output signal is measured with MC2.
The reference temperature also measured with MC2.
MC2-TE and MC2-MF models are capable of calibrating a temperature sensors .
Remember the following conditions:
•
•
If the sensor to be calibrated is a thermocouple, the reference
thermometer needs to be an RTD sensor.
If the sensor to be calibrated is an RTD sensor, the reference
thermometer needs to be a thermocouple.
Preparations
1. Place the sensor of the instrument and the reference sensor
into the calibration bath/dry block. Connect them to suitable
terminals in MC2. Select one of the available reference junction methods for the thermocouple:
•
•
•
•
MC2’s internal reference junction is used.
The reference junction temperature is fixed to 0°C.
The reference junction temperature is manually entered.
The reference junction temperature is measured externally using an RTD connected to the RTD terminals.
See Part C for additional information concerning the reference junction methods.
2. Configure one of MC2’s windows to measure T/C temperature
and the other to measure RTD temperature.
3. Test the connections.
118
Calibrating an Instrument
Calibration
1. Set the temperature of the bath/dry block to the required calibration point. Wait until the temperature stabilizes.
2. Record the input and output signals and also the error value, if
applicable.
3. Proceed to next calibration point (step 1) if applicable.
4. Continue by either adjusting the instrument, starting another
calibration repeat or ending the calibration.
Hint!
If one of the sensors cannot be detached from its transmitter, connect the transmitter’s output signal to MC2’s measuring terminals
and use one of the error display modes to convert the (standard)
output signal to a more usable format. See Part B for additional
information concerning display modes.
119
Calibration
Pneumatic Pressure Transmitters and Converters
This procedure suits all instruments with both a pressure input and
a pressure output signal. Both the input and output signal range
should be measurable with MC2.
To be able to perform the calibration, an internal pressure module
need to be installed and an external pressure module need also be
connected to MC2. The example picture below has the instrument’s
input connected to the internal pressure module and the instrument’s
output connected to the external pressure module. The pressure
modules may also be used the other way. All that matters is that the
pressure module’s span and accuracy suits the pressure signal.
MC2-PE and MC2-MF models are capable of calibrating a pneumatic pressure transmitter/converter.
Preparations
1. Connect the instrument’s input to the selected pressure module (internal or external).
2. Connect the pressure source both to the instrument’s input
and to the pressure module.
3. Connect the instrument’s output to the selected pressure module (internal or external).
4. Configure one of MC2’s windows to measure the input pressure and the other to measure the output pressure .
5. Test the connections.
