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 26 and Safety

Precautions and Warnings on page 27.

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.

There is no galvanic isolation between the connectors on the left side as well as the internal pressure module connector.

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.

• 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 .

• Models MF and TE have the following additional terminals:

Thermocouple measurement and simulation, RTD measurement and simulation, voltage , current , frequency and pulse generation.

8 MC2 User Guide

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 shock proof so the data is not lost when the calibrator is transported.

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:

• Press F1 / Contrast when either viewing the welcome screen or the General Settings screen.

• Use the up and down arrow keys to change the contrast.

The changed settings are automatically saved as default settings.

10 MC2 User Guide

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:

- Amount:

1.5 V

The charger for rechargeable batteries operates in the following environments:

- Voltage:

- Frequency:

100 B 240 VAC

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.

See also chapter Capacity Indication on page 12.

MC2 User Guide 11

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).

B a t t e r y s t a t u s B a t t e r y s t a t u s

E s t i m a t e d t i m e l e f t : 2 h 1 4 m i n

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).

Capacity Indication

When taking MC2 into use for the first time or if you reset MC2 or remove/replace the batteries, "teach" the capacity of the batteries to

MC2's charging electronics by doing as follows:

1. Fully charge the batteries (approx. 5 h with no extra load).

2. Use the calibrator until the batteries are empty, i.e. MC2 automatically shuts itself down.

3. Recharge the batteries for use.

12 MC2 User Guide

Batteries

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.

4. 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.

Batteries

Notes.

The driver has been tested on Windows XP, Windows 2000,

Windows Vista and in Windows 7, 32 and 64 bit versions.

Windows 95, 98, NT4, ME operating systems are not supported.

If you connect MC2 to another USB port than the one used when installing the driver, Windows

XP and Windows

2000 may ask you to install the driver again.

• In Windows

XP : Install the driver automatically. If it fails, do the full installation as presented previously in this chapter.

• In Windows

2000 : You have to do the full installation as presented previously in this chapter.

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.

MC2 User Guide 27

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 gas-tight 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.

28 MC2 User Guide

Safety Precautions and Warnings

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.

External Pressure Modules: Use only the pressure media stated on the pressure module. Use of wrong type of Pressure Media may destroy the pressure module.

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

Booklet 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.

MC2 User Guide 29

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.

Pressure Measurement

Notes.

For more information on pressure measurement and internal/external pressure modules, see chapter Things to Consider when

Measuring Pressure on page 108.

For information on creating custom pressure units, see Part C, chapter Custom Pressure Units on page 106.

When using high pressure modules, you may measure pseudo absolute pressure. Open the setup window (select F1 / Setup or

F2 / Setup ), change the pressure type to absolute. Then an extra field for entering the barometric pressure appears. Enter the barometric pressure manually and press F3 / Ok . MC2 adds the manually entered barometric pressure to the measured gauge pressure and displays the (pseudo) absolute pressure.

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 external 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:

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.

MC2 User Guide 45

Measuring

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 or

F2 / Setup ) and select F1 / Zero Pressure . If a secondary pressure module is active in the selected window (see Tools Menu on page

67), 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).

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.

The following picture displays the active terminals:

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.

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.

Thermocouple Simulation

If the thermocouple to be simulated is not available MC2's sensor list, select one of the " V oltage + R eference J unction " 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 possible. 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 48.

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.

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.

If applicable, disable MC2's auto-off functionality during the test. If the test lasts longer than the auto-off delay, MC2 is shut down while the test is still incomplete.

An external pressure module (EXT) connected to MC2 during a leak/stability test cannot be taken into use in the window were the leak/stability test is under progress.

Hint.

If you have a pressure transmitter connected to a pressure measurement system and you want to check the pressure decrease without altering the pressure connections, do as follows:

Connect the electrical output of the pressure transmitter to MC2. Use

MC2's scaling utility to scale the output signal back to pressure units.

Start the leak/stability test for the scaled measurement and there you can see the leak in pressure units. More info on scaling in chapter

Maximum - Minimum

± Calculates the difference between the maximum and minimum measurement value found after a measurement was started or it was reset.

Cumulative Average x Calculates the cumulative average of measurements after a measurement was started or it was reset.

Cumulative average means that, after the calculation is started, every new measurement is included in the average calculation. Thus the amount of measurements included in the cumulative average increases all the time and the average value's change rate typically gets smaller with time.

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.

108 MC2 User Guide

Things to Consider when Measuring Pressure

Pressure Modules and their Naming Conventions

MC2's software refer to pressure modules as follows:

IPM200mC which means that there is an i n ternal p ressure m odule 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:

• The number defines the max. nominal pressure in the SI pressure unit bar .

• If the number is followed by a small " m ", the given max. nominal pressure is given in mbar .

• The additional letter C means the pressure module is a compound module with an ability to also measure negative gauge pressures.

Examples:

Name Measurement range in psi

Notes.

IPM200mC

IPM160

±200 mbar

-1 I 20 bar

0 I 160 bar

± 3

-14.5 I 300

0 I 2400

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 Transfer Function field is set to Square Rooting ( √ x ).

2. Use Scaling to convert the instrument's output signal to a suitable format and again, make sure the Transfer Function field is set to Square Rooting ( √ x ).

Display Modes as well as scaling is discussed in chapter Tools

Thermocouple Measurement/Simulation, Connections and Troubleshooting

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 ".

Error situations

The easiest way to avoid errors in thermocouple measurement and simulation is to check carefully the used wiring and the Reference

Junction mode. The following table describes the typical error situations and possible causes/corrections when working with thermocouples:

PROBLEM

MC2 (or the instrument under test when simulating thermovoltages) measures the temperature/millivolt signal, but the displayed temperature reading is all wrong.

(The error may vary from 0 to about ±50 °C depending on the type of the error)

CAUSE

• The thermocouple type selected in MC2 does not correspond with the used thermocouple.

• The selected Reference Junction mode is not in accordance with the used wiring.

• Extension or compensation cable type or connections are incorrect.

• The polarity of the cables are incorrect.

MC2 (or the instrument under test) displays random readings during thermocouple measurement.

MC2 displays unstable readings during thermocouple simulation.

• Incorrect connections.

• The wiring is broken.

• Interference from a mobile phone or a radio transmitter affects the measurement.

• The instrument to be calibrated uses voltage pulses to detect an open sensor.

When MC2 detects these pulses, it tries to compensate for them, which causes the unstable output. Prevent these pulses for the time of calibration. Refer to the service manual of the instrument to be calibrated on how to prevent these open sensor detection pulses.

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

When 4-wire system is used, MC2 displays the symbol shown on the left.

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 4-wire method gives the resistance between the terminals of the resistor, it is insensitive to the resistance of the connection wires.

3-wire System

When 3-wire system is used, MC2 displays the symbol shown on the left.

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.

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:

Each internal or external pressure measurement runs independently.

One electrical measurement in the Measure terminals.

One electrical measurement and one electrical generation/simulation in the Temperature / Generate terminals.

Additionally, all of the connectors on the left side of MC2 may have an independent task.

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.

Calibrating an Instrument

A Calibration Procedure Using MC2

The most convenient way to calibrate instruments with MC2 is using one of the error display modes described in chapter Tools Menu presented on page 67.

126

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.

MC2 User Guide

Examples of Instrument Calibration

The following pages contain a few examples of how to calibrate an instrument using MC2.

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 111 and

External Reference Junction on page 112.

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.

6. Configure one of MC2's windows to simulate temperature ( T/C Sensor

Simulation or RTD Sensor Simulation ). Test the connections.

130 MC2 User Guide

Examples of Instrument Calibration

Calibration

1. Enter the temperature to be simulated There are two different strategies on how to set the temperature:

• 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.

• Do not adjust the simulated value, but enter the actual reading as the output value. This method suits indicators with digital display. It is also handy when calibrating other types of indicators/recorders with an input signal that do not support 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 adapted for any kind of indicator/recorder.

Change the input signal connections/settings according to the instrument's 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.

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.

132 MC2 User Guide

Examples of Instrument Calibration

Calibration

Note.

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

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.

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.

134 MC2 User Guide

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.

MC2 User Guide 135

Calibrating an Instrument

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 a 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 .
