General

Introduction

Congratulations for selecting the ultimate calibration tool! MC5 is a documenting All-In-One Multifunction Calibrator with cali-

bration capability of pressure, temperature, electrical and frequency signals. As a member of Beamex’s QCAL Quality Calibration family it is of course able to communicate with the available QCAL calibration software. MC5’s modularity allows customized construction. If requirements increase in the future, new functionality may be added by getting additional modules, e.g. adding temperature and/or electrical modules to an MC5 that previously only included pressure modules.

Thanks to the logical user interface MC5 is very easy to use. The large backlit graphical display guides the user in different languages and it displays results both numerically and graphically.

MC5 performs automatic calibration of pressure, electrical and temperature process instruments. It is capable of communicating with external devices such as pressure controllers. MC5 also communicates with HART field instruments.

MC5 represents the state of the art in accuracy, adaptability and allround usability.

About This Manual

This User Guide is divided in four parts: A, B, C and D.

• Part A discusses general matters. There is also a chapter about safety.

• Part B describes the basic use of MC5 such as measuring and generating signals.

• Part C handles configuration level usage, some optional software utilities and also offers some additional information concerning pressure measurement, RTD and T/C measurement/simulation.

• Part D concentrates on calibration and matters related to calibration like handling instrument data.

The even page header displays the title of the active part. The odd page header displays the main subject (Heading level 1). The header of each odd page also indicates the active part as shown in the adjacent picture (with Part B active). Use the information provided in the headers as a quick guide when searching for a particular subject.

Unpacking and Inspection

At the factory each new MC5 passes a careful inspection. It should be free of scrapes and scratches and in proper operation order upon receipt. The receiver should, however, inspect the unit for any damage that may have occurred during transit. If there are signs of obvious mechanical damage, package contents are incomplete, or the instrument does not operate according to specifications, contact the purchasing sales office as soon as possible. The standard accessories are as follows:

• Calibration Certificate

• This User Guide

• Warranty Card

• Battery Pack, NiMH

• Charger for the Battery Pack

• Computer communication cable

• If any internal pressure modules are present:

A pressure hose set

• If the E module is present: Two test leads and clips

• If the ET module is present: Four additional test leads and

two clips

Introduction

For a description of available hardware and software options, see MC5’s Modularity and Options on page 24.

If you have to return the instrument to the factory for any reason, use the original packing whenever possible. Include a detailed description of the reason for the return.

Warning! The accessory polyurethane hose supplied with the calibrator

is rated to the maximum pressure of 20 bar at 21°C (290 psi at 70°F). Applying higher pressure can be hazardous.

Note. Keep in mind that the previous picture (as well as all pictures of

MC5 in this manual) has an example configuration of modules. The configuration of your MC5 may vary significantly from the one in the picture.

The Upper Panel

The upper panel has 5 places for the following modules/connectors:

External Pressure Modules

MC5 has a connector for External Pressure Modules (EXTs). The connector is located on the right hand side of the upper panel and is marked with PX1 in a sticker on the upper panel.

Internal Pressure Modules

Up to three Internal Pressure Modules may be installed in MC5. One of them may be an internal barometric module. Although the Barometric Module reserves the space allocated for an internal pressure module it does not need a connector in the upper panel, so the space reserved for the connector may be used for, e.g. a connector for an External Pressure Module.

The connectors for Internal Pressure modules start from the second connector on the left. The possible Barometric Module is always located as second from right and it measures the barometric pressure through a connection in the back panel of MC5. Normally nothing need to connected to the barometric pressure module’s connector.

Internal pressure modules are marked with P1 … P3. The Barometric Module does not have an abbreviation. The whole name is written on the module.

The recommended pressure medium for all internal pressure modules is clean air. Clean non-corrosive liquids may optionally be used in modules with a measuring range of 20 bar/300 psi or more. Avoid spilling liquid on MC5 when connecting/disconnecting pressure hoses to/from pressure modules.

To avoid damaging the calibrator, use hand tightening only when connecting the pressure measurement hoses (max. torque 5 Nm, approx. 3.6 lbf ft). If the use of tools is required to secure the connection (typically pressure modules with a pressure range higher than 20 bar), apply the counterforce with a spanner on the connector body’s hexagonal part.

The overpressure protection of the internal pressure modules vents to the back of the calibrator. 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.

MC5 Hardware

General

The Connectors on the Left Side of MC5

The left side of MC5 (front view) has three connectors as follows:

Environment Temperature Interface

This connector is for an optional temperature measurement sensor. This sensor is only meant for environment temperature measurement. It should not be used as a reference sensor when calibrating temperature instruments.

Computer/Printer Interface

The COMP/PRT connector may be used when connecting to a serial port in a PC. The PC may have a calibration software capable of communicating with MC5 or, e.g. a software that reads data logging results in MC5 and transfers them to a PC.

The same connector can be used when MC5 is connected to an optional portable printer. The printer may be used for printouts of user interface screens (e.g. calibrations results).

Warning! Use only cables provided by Beamex when connecting MC5 to

a PC or a printer.

Auxiliary Instrument Interface

The AUX connector is used when connecting pressure controllers, temperature baths/dry blocks etc. to MC5.

Using auxiliary instruments is described in Part C of this manual.

The Front Panel

The front panel has several sections. Some of them are pointed out with a callout in the picture of Operational Sections and Connections, and some of them not (e.g. display and keyboard). The ones with a callout are discussed first in the following paragraphs.

Electrical Module (E module)

The E module can measure the following quantities: voltage, cur- rent and frequency. It can also be used when counting pulses or detecting the state of a switch. Additionally there is a possibility to generate current and supply an instrument with a 24 VDC power

supply. The E module also includes the optional HART modem. This allows

communication with an instrument with HART capabilities. When HART is used in conjunction with MC5’s power supply, an internal 270 ohm resistor needed for HART communication is automatically included.

Additional information on calibrating HART instruments is in Appendix 1.

The ET module is specially designed for temperature instrument calibration needs. It is not however restricted to only temperature instrument use because it can also generate voltage, current, fre- quency and pulses.

Measuring capabilities:

• Low Voltage measurement and T/C measurement using either the internal reference junction or the Low Voltage connectors.

• Resistance and RTD measurement.

Generation/simulation capabilities:

• T/C simulation using either the internal reference junction or the Low Voltage connectors.

General

Reference Junction Module

The T/C measurement/simulation internal reference junction is an optional addition to the ET module. It is specially designed for MC5 and therefore best suited for reference junction compensation when calibrating thermocouples or instruments connected to a thermocouple.

The Reference Junction Module is suited for all standard T/C plugs and stripped wires. Open the fixing screw on the left side of MC5 before connecting the wires/plug to the Reference Junction Module. Make sure to connect the wires/plug as the polarity is indicated on the Reference Junction Module. Remember to tighten the fastening screw when the wires/plug are connected. Hand tightening is adequate. Do not pull out the wires/plug without first opening the fixing screw. Otherwise you might damage the contact surface of the connectors.

T/C measurement and simulation may also be done without the internal reference junction by using the Low Voltage terminals in the ET module. Then the reference junction arrangements have to be done outside MC5 and the correct reference junction settings as well as the reference junction temperature have to be informed to MC5.

Part B of this manual describes in detail what kind of reference junction settings are available.

Keyboard

MC5 Hardware

The keys on the MC5’s keyboard are grouped according to their function as follows:

The Cursor Keys and the Enter Key

The Cursor keys and the Enter key are located close to the upper left corner of the display. The Cursor 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 finishes the entering of values.

The Keys Above the Display

The Light key toggles the back light of the display on and off. It is also used when setting the contrast and the brightness of the display (see chapter Display on page 8) and when printing screenshots (see chapter Printing on page 17).

The Help key displays case sensitive help. The On/Off key switches MC5 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 MC5.

General

Pressing the +/- key toggles the sign of the entered numeric value. Note. The +/- key is applicable only in numeric fields.

The Decimal key adds the decimal point to the numeric value that is currently edited.

The Function Keys

The Function Keys are located below the display. The meaning of each Function Key varies depending on the situation. The lower part of the display indicates what the Function Key stands for at the moment.

The Numeric Keys

The Numeric keys are not only used when entering numbers:

• Keys 1 to 7 are used as menu selector keys.

• Keys 0 and 8 are used to scroll through several pages of menu

options. They may also be used when browsing through options in a pop-up list.

• Key 9 can be used when accepting a selection or when finishing a data entry. The functionality of the 9 key is almost similar to the bers, the 9 key produces the number 9. To finish entering a number, you will have to use the Function Key when available.

key, except for one situation: When entering num-

key or use the D/OK

Memory

MC5 has a dynamic memory allocation system. This means that there is not a specific area of memory reserved for, e.g. instrument data. All free memory may be used for anything that requires more memory. Thus there is no exact limit for the number of instruments that MC5 can maintain in its memory. It all depends on how much memory is allocated by other data.

Batteries

Full batteries: Empty batteries:

MC5 Hardware

MC5 supports the use of both rechargeable batteries and alkaline batteries. When using alkaline batteries, you need a Dry Battery Cartridge. MC5 automatically detects the battery type.

The alkaline batteries to be used are:

- Cell Voltage: 1.5 V

- Amount: 6

- Type: AA

The charger for rechargeable batteries operates in the following environments:

- Voltage: 100 … 240 VAC,

- Frequency: 50/60 Hz

The charging electronics is in the Battery Pack. Therefore the batteries may be charged although the Battery Pack is disconnected from MC5’s Base Unit. If you have two sets of rechargeable batteries you may charge the disconnected Battery Pack while at the same time use MC5 with the connected Battery Pack.

The maximum operating time without recharging varies depending on the usage and brightness setting of the display light. Also the generated output current and the usage of the 24V transmitter supply affect the maximum operating time. Even with constant maximum load, the standard rechargeable batteries should last for 6 hours. A good average operating time is 10 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.

The upper left corner of MC5’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. MC5’s memory and the 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 MC5 is not in use.

Do not leave MC5 without a Battery Pack or a Dry Battery Cartridge for a long time. MC5 may loose its settings if it is left without a support voltage for an extended period.

General

About the Charger and the Charging Procedure

The charger is connected to the charger connector at the bottom of MC5. The charging electronics informs you of the phases of the charging procedure with the help of the charge status light.

Charger connector

Charge status light

When connecting the charger, the charging electronics first checks the charge level of the batteries. At this stage, no light is visible in the charge status light.

When the charge status light is red, a recharging is either starting (blinking red light) or in progress (constant red light). MC5 may be used during the recharging phase. Empty batteries are fully charged in approx. 2½ hours.

When the charge status light is green, the batteries are charged. At this stage the charging electronics provide a support voltage that prevents the batteries from discharging

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 40 °C (104 °F).

Removing/Replacing the Battery Pack

To remove or replace the Battery Pack, perform the following procedure:

1. 2.

1. Turn MC5 upside down (the display facing the table top) and

lift the support.

2. Pull the lever that is hidden under the support. The Battery

Pack pops out allowing you to pull it out.

To replace the Battery Pack, simply slide it on its place. When you hear a click, the Battery Pack is secured in its place.

MC5 Hardware

Note. Although the Base Unit is IP65 protected, the Battery Pack is not.

The Battery Pack has holes in order to vent generated gas and heat. Avoid exposing the Battery Pack to liquids.

General

Support for Table Top Use

The support gives you a good viewing angle when MC5 is placed on a table top. Lift the support at the back of MC5 and place MC5 on the table top as shown in the picture.

The Wrist Strap and the Neck Support Strap

MC5 has a wrist strap to enable ease of use when MC5 is held in one hand. The neck support strap helps you during field calibration: Position MC5 in an angle that allows reading the display when working. Alternatively: Hang MC5 from, e.g. a valve shaft so that the display is on the same level as your eyes. Then your hands are free for working with the connections etc.

The Optional Carrying Case

MC5’s soft carrying case is practical when moving from a location to another. The carrying case can also be used for transporting utilities, like:

• Test hoses, test leads and clips

• External pressure modules

• A pressure pump

• Temperature sensors

• Charger and its cable

• User Guide (this book)

The carrying case is suited for use in normal industrial environment.

MC5 Firmware

MC5’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 30 for more information on updating the firmware in your MC5.

General Description

The following picture shortly describes the functions of the firmware. All main functions are marked with a black border. Each main function has several tasks which are displayed as shaded boxes without a black border.

Startup Procedure

The following chapters briefly describe each main function.

Every time MC5 is started the Startup Procedure checks the functionality of the device by performing a self test.

If the self-test is passed successfully, some basic calibrator data is displayed.

After that MC5 automatically proceeds to Basic Mode. A more comprehensive description of the Startup Procedure is in the beginning of Part B of this manual.

Basic Mode

Maintenance

Calibration Mode

General

In Basic Mode you can measure and generate/simulate signals. There are two separately configurable windows available. Basic Mode is often used for testing connections before starting the actual calibration procedure of an instrument.

Stepping and Ramping tools enable generating/simulating signals that vary with time.

All main functions of Basic Mode are described in part B of this manual.

Part C concentrates on Basis State’s higher level functions and additional information.

This main function handles calibrator configuration settings. Additionally there is the possibility to recalibrate MC5 (requires a

password). Maintenance level subjects are handled in Part C of this Manual.

MC5’s main duty is calibrating instruments. Therefore very special attention was directed on this matter when creating the calibrator. MC5 may be used as a stand-alone calibrator i.e. all instrument data and calibration history data is saved in MC5’s own memory. Optionally MC5 also communicates with calibration software.

MC5 supports the use of instruction texts. They help the technician to perform the calibration as fluently as possible. You may enter three kinds of instruction texts: Starting Guide, Adjusting Guide and Finishing Guide. Additionally, calibration notes can be entered after the calibration procedure.

More calibration related information is available in Part D of this manual.

Calibration Results

The graphical representation as well as numeric data of the calibration results may be viewed in MC5 (and printed if the optional printer is available). Transferring the results to QCAL® calibration software makes it possible to view the results in PC environment.

More information concerning calibration results is presented in Part D of this manual.

The main elements of the User window can be seen in the following picture:

All possible elements are not included in the previous picture, but the important ones are discussed in the following chapters.

The Status Bar

The Status Bar at the top of the display is visible all the time. It is divided into four main sections.

The first (leftmost) section displays the charge level of the battery. The battery symbol is replaced by a plug symbol ( ) if you are using the battery charger together with the optional Dry Battery Cartridge. In this case the battery charger acts as a battery eliminator. The second section displays the time and date. The third section displays the temperature measured with the optional environment sensor, if the sensor is connected to MC5.

The fourth section (rightmost) section displays additional information in the form of symbols, like:

Note that the fourth section is empty for most of the time. The symbols are visible only when needed.

All MC5’s are built around the Base Unit (BU). All other modules are optional, but at least one of the optional hardware modules has to be available in order to measure/generate/simulate a signal.

There are some limits on the total amount of certain modules/ connectors. See chapter The Upper Panel on page 5 for additional information concerning this matter.

E module’s HART communication requires that the respective firmware option is installed.

Other Connectable devices

There is an increasing number of devices that can be connected to MC5. The following list includes connectable devices that are either already connectable or will be in soon to come firmware updates (valid when this manual was printed):

• External Pressure Modules (EXT)

• Environment temperature sensor (ENV)

• Battery operated portable printer (COMP/PRT)

• Pressure Controllers: POC4,

Druck DPI510 and Druck DPI 515 (AUX)

• Temperature Baths/Dry Blocks: Isotech, TekKnow, Ametek/Jofra and HART Scientific (AUX).

Additional information on the battery operated portable printer, pressure controllers and temperature baths/dry blocks is available in part C of this manual.

Firmware options

The standard firmware shipped with MC5 is capable of performing all normal measurement, generation/simulation and calibration tasks. The optional tools give you additional features that enhance MC5’s functionality.

The following firmware options are either already available or will be in soon to come firmware updates (valid when this manual was printed):

• Special temperature sensors

• Communication with QCAL® software

• Drivers for External Devices that are connected to the AUX

interface.

• HART communication (Requires the E module)

• Multichannel datalogging

MC5’s Modularity and Options

General

Safety

MC5’s case is water/dust proof (IP65). The battery pack does however have holes to enable proper ventilation and heat transfer. So be careful when working in wet conditions.

The materials of MC5’s case withstand normal industrial conditions. MC5 endures shocks with the help of the built in impact protectors

Internal pressure modules with a measuring range of 6 bar (90 psi) or less are overpressure protected. If the measurement pressure of a pressure module exceeds the module’s maximum pressure value, the overpressure protector vents excess pressure through a hole in the rear of the case.

Certifications and Compliances (EC Declaration of Conformity)

MC5 conforms to the EMC directive 89/336/EEC as attested by conformity with the following harmonized standards:

EN 50081-1 Emission, EN 50081-1 Immunity, EN 61000-3-2 Harmonic currents, EN 61000-3-3 Voltage fluctuations,

and the low voltage directive 73/23/EEC as attested by conformity with the following harmonized standard:

EN 60950 Low Voltage.

Safety Precautions and Warnings

MC5 calibrator is a precision calibration tool that should be used by skilled people. Working with MC5 involves the usage of pressure, temperature 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 MC5 only if you are certain of that it can be used safely. Safe use of MC5 is no longer possible if one or more of the following cases are true:

• When the case of MC5 is evidently damaged

• When MC5 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.

General Warnings

Use only cables provided by Beamex when connecting MC5 to a PC or a printer.

Use the MC5 battery charger in a non-hazardous indoor location only and only with Beamex calibrators.

Only use the printer that is available as an option. Using any other printers may damage the printer or MC5 or even both of them.

MC5 uses alkaline batteries or a rechargeable Battery Pack. 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.

The charger should only be used indoors and the temperature should not exceed 40 °C (104 °F).

Safety

General

Warnings Concerning the use of Electrical Modules (E and ET)

The measurement and generation terminals of MC5 are protected against over voltage and over current as far as it has been possible without affecting the accuracy. The circuits are designed so, that you can connect a voltage source 50VDC/2A between any terminals without damaging the device. However, long exposure to this kind of stress may affect the accuracy.

Although there is a galvanic isolation between MC5’s ET and E modules, it is for functional purposes only. The max. 50 V restriction applies between these modules too.

Maximum output voltage from MC5’s terminals is below 30 V. If you, however, connect together voltages from the ET and E sections or if you connect external voltages to MC5, the resulting voltage may be high enough to be hazardous.

General Warnings Concerning Pressure Measurement

The accessory polyurethane hose supplied with an MC5 with pressure modules is rated to the maximum pressure of 20 bar at 21°C (290 psi at 70°F). Applying higher pressure can be hazardous.

To avoid damaging the calibrator, use hand tightening only when connecting the pressure measurement hoses (max. torque 5 Nm). If the use of tools is required to secure the connection (typically pressure modules with a pressure range of 20 bar or more), 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.

Always use the pressure media stated in the module’s sticker. Using unsuitable pressure media may destroy the pressure module. The internal module’s sticker is located at the rear of MC5. External modules have the sticker on the module itself.

Never exceed the maximum pressure of a pressure module, be it internal or external. The pressure module’s maximum pressure is stated on the module’s sticker. The maximum pressure of external modules is also mentioned in the Instruction Leaflet that is provided with the external module.

Never plug a hose with your hands or put the hands in front of a gas spray coming from a leakage. A gas bubble in the blood circulation can cause death.

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.

Safety

Service

Firmware Update

General

Only qualified service personnel may perform higher level maintenance for MC5. Never open the case unless have explicit in- structions from Beamex or a local representative.

There are, however a few things that anyone using MC5 may do.

The quickest way to see if a new firmware version is available is checking out Beamex’s web site (http://www.beamex.com). Go to the “Downloads” page and see what it says about MC5 firmware versions and downloads.

All you need is a Personal Computer and the Computer communication cable that connects MC5 to one of the serial ports in your PC.

Remember to backup all the instrument data in MC5, using e.g. a calibration management software. Also check for possible release notes accompanying the updated file.

Recalibrating MC5

The Battery Charger

Only laboratories approved by Beamex may recalibrate MC5. Contact Beamex or your local representative for information concerning the recalibration of MC5. Contact information is on the first pages of this User Guide.

The charger is not intended to be serviced. When unusable it can be thrown away according to local waste disposal regulations.

Service

Cleaning MC5

If MC5 needs cleaning, use cloth soaked with a mild solution of tall oil soap (pine soap). Wait a a few minutes and then rinse using a cloth moistened with pure water. Never use any strong detergents.

Cleaning the Contacts of the Internal Reference Junction Module

The contacts of the Internal Reference Junction Block may need cleaning from time to time. The time period varies depending on the environment MC5 is used in.

Carefully open the cover of the Internal Reference Junction Block by using a screwdriver as a wrench. Now you can see the contacts. Remove all impurities and press back the cover. The cover is secured when you hear a click.

If a module’s version number cannot be seen, the module is not included in the MC5 at hand.

The calibration due date that is listed in the startup window is the earliest calibration due date for all connected modules. If the calibrator requires recalibration, MC5 stops at the calibrator information window and the text “Calibrate Soon” appears below the calibration due date row.

Basic Mode, Defined

Every time MC5 is switched on, the startup procedure ends in Basic Mode.

All non-calibration related measurements and generations are performed in the Basic Mode. Briefly: in Basic Mode MC5 works like a high quality multimeter. When returning from MC5’s higher level operations (calibration, viewing of calibration results, calibrator and user configurations), you always return to the Basic Mode.

Measuring

All measurements in Basic Mode require that you first select the Window to be used (Commands: Start with D/Menu and continue either with A/Window 1 Setup or B/Window 2 Setup). Each measurement has its own unique 1/Quantity and 2/Function/Port set- tings in their window’s menu. The other window menu settings, e.g. measuring unit, refine the measurement characteristics.

When presenting measurements in this manual, the first paragraph tells the module (or modules) that is/are required for the measurement. Because of MC5’s modularity you may or may not have the required module. If the module is not included in your MC5, the

1/Quantity and 2/Function/Port settings needed for the measure-

ment are not available as choices in the pop-up lists. Each measurement also has at least one picture with a circle around

some of MC5’s terminals, like the one below.

Limit Switch Test

A limit switch test displays the opening and closing point of a limit switch. MC5 supports limit switch testing of any type of limit switches as long as MC5 is able to either measure or generate/simulate the switch’s input signal and is also capable of detecting the switch state.

Notes. Basic Mode’s limit switch test is a restricted version compared to

the limit switch test available in Calibration Mode. This test gives you the approximates of the latest opening and closing points and also the current switch status. The limit switch test in Calibration Mode offers more accurate results and additionally, statistical data of repeated switch tests. More of the limit switch test in Calibration Mode in Part D of this manual.

In Basic Mode MC5 does not support limit switch testing when simulating resistance or an RTD sensor. The limit switch test in Calibration Mode also supports resistance and RTD sensor input.

Performing the Limit Switch Test

Configure, e.g. Window 1 to either measure or generate/simulate the switch’s input signal (Function keys D/Menu and

A/Window 1 Setup in Basic Mode) and

Window 2 for switch state detection (Function keys D/Menu and B/Window 2 Setup in Basic Mode). It doesn’t matter which window is assigned for which function as long as both the switch’s input signal and the switch state are available for MC5.

Slowly change the switch’s input signal and watch how the “Opened @” and “Closed

@” data is updated as the switch changes

its state.

Special Measurements

Special measurements are extra utilities that can be activated to perform a special function alongside the normal measurement.

Only one of the special measurements may be activated at a given time for each window/quantity. Activating another special measurement deactivates the earlier special measurement in the same window (or the earlier special measurement using the same quantity).

All special measurements are started similarly:

• Select D/Menu followed by B/Window 2 Setup if needed.

• As the special measurement setting command is located in

the window setup’s submenu, select either the numerical key

or the cursor key

• Then select 1/Special Measurements and the type of spe- cial measurement from the provided pop-up list (or deactivate a special measurement by selecting the option “None”).

Some of the special measurements do not require any additional information. They start immediately after they are activated. Rate

of Change Measurement, Special Filtering and Resolution, Redundant Measurement and Deviation Measurement do how-

ever need some additional information. Therefore when you activate them you will have to enter the required additional information before the special measurement is started.

Notes. Special measurements are only available in Basic Mode. If you change any of the main settings of the measurement (Quan-

tity, Funct/Port), the defined special measurement is deactivated.

Generating/Simulating

General

This chapter and the subchapters describe only how to generate/ simulate signals using MC5’s own modules. Part C discusses the use of external devices connected to the auxiliary interface.

MC5 is capable to perform the following generation/simulation functions:

• Voltage generation

• Current generation

• Frequency and pulse generation

• Thermocouple simulation

• RTD and resistance simulation

Generation/simulation in Basic Mode require that you first select the Window to be used (Commands: Start with D/Menu and continue either with A/Window 1 Setup or B/Window 2 Setup). Each generation/simulation has its own unique 1/Quantity and 2/Func-

tion/Port settings in their window’s menu. The other window menu

settings (generation/simulation unit etc.) refine the generation/simulation characteristics.

The presentation of each generation/simulation begins with a paragraph defining the modules that include terminals required for the generation/simulation (Most generated/simulated signals are done with the ET module but current generation may also be done with the E module). Because of MC5’s modularity you may or may not have the required module. If the module is not included in your MC5, the 1/Quantity and 2/Function/Port settings needed for the generation/simulation are not available as choices in the pop-up lists.

Each generation/simulation also has at least one picture with a circle around some of MC5’s terminals, like the one below.

Generating/Simulating

Warnings! When selecting a generation/simulation function, MC5 always

starts with zero output (not when simulating a resistance). This is done to prevent damages in the connected instrument.

Be careful when increasing the generated/simulated signal. If an instrument that cannot withstand the generated signal is connected to MC5, the instrument may get seriously damaged.

Changing the Value of the Generated/Simulated Signal

Move the field indicator on the display until it surrounds the value of generated/simulated signal (use the B/Field Function Key or the cursor keys).

Enter the new value using the numeric keys. You may cancel the editing by pressing the A/Cancel Function Key. The C/çDelete Function Key removes the rightmost digit.

Note. The output current of the E module is a “pure” analog signal without

any embedded HART signal.

Notes applying to both the ET: I(gen) and the E: I(control) ports: Check the polarity of your connections. The arrows in the previous

pictures describe the correct flow of current. If the loop resistance of the external circuit is too high or infinite, the

message “O.LOAD” is displayed until the load is reasonable.

Warnings! Make sure that you don’t exceed the maximum current allowed

by the instrument under test. If you open the mA generation loop, MC5 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.

Generating/Simulating

Note. If the resistance of the external circuit in voltage generation is very

low (obvious short circuit), the message “O.LOAD” is displayed until the load is reasonable.

Hint! Low voltage generation can be used when calibrating instruments

with millivolt input. You can use it also to simulate special thermocouples not defined in MC5. If you simulate a thermocouple in millivolt mode, you must convert from temperature to millivolts manually.

Warning! If you short circuit the voltage output, MC5 tries to maintain the

voltage by increasing the output current. If you then remove the short circuit, 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 V output before connecting the circuit.

RTD and Resistance Simulation

MC5 mimics the RTD or the resistor to be measured by the instrument under test. The instrument under test generates the current for the resistance measurement. MC5 controls the voltage across its terminals so that the resistance (voltage to current ratio) corresponds to the simulated temperature or resistance. MC5 can simulate resistance between 1 to 4000 ohm.

RTD and resistance simulation terminals are located in the ET module. Required settings Options/description

Quantity RTD-Temp. (for RTD simulation)

Resistance (for resistance simulation)

Funct/Port ET: RTD(sim) (for RTD simulation)

ET: R(sim) (for resistance simulation)

Sensor Type Available RTD sensors. Only needed

when doing RTD simulation.

The correct resistance value is between the resistance simulation terminals of the calibrator. Use of 2-, 3- or 4-wire connection is up to the receiver instrument. Use only the two leftmost R, RTD terminals with every wiring option. Connect the possible third and fourth wire according to the requirements of the connected instrument, but use only the two leftmost R, RTD terminals.

Notes. In RTD and resistance simulation MC5

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 “H.CURR”. Respectively, if the measurement current is so low that it may affect the accuracy, the message “L.CURR” is displayed.

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.

Generating/Simulating

Thermocouple Simulation

MC5 is able to mimic a thermocouple at given temperatures. This property is called thermocouple simulation. It enables checking and calibration of temperature indicators, recorders, transmitters and other equipment related to temperature measurement with a thermocouple probe.

In thermocouple simulation the original thermocouple is disconnected from the instrument under test and replaced with MC5. To the instrument under test MC5 appears as a thermocouple at the given temperature.

Thermocouple simulation terminals are located in the ET module. Required settings Options/description

Startup and Basic Operation

Notes. If the resistance of the external circuit in thermocouple simulation is

very low (obvious short circuit), the message “O.LOAD” is displayed until the load is reasonable.

Check that the instrument under test is set for the same thermocouple type as selected in MC5. If the type is not one of the available types, you should simulate in millivolt mode and convert from temperature to millivolts manually. More information concerning millivolt generation is in chapter Voltage Generation on page 62.

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 MC5’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 44.

Warning! If you short circuit the thermocouple simulation output, MC5

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 ET module’s R, RTD connectors, there is no galvanic isolation between the thermocouple and the RTD sensor.

Problems with thermovoltage simulation? See Error situations on page 100.

Special Generations

Manual change of generated signals is sometimes a restriction. Therefore MC5 includes Stepping and Ramping as standard utilities for creating automatically alternating output signals (special generations).

To be able to start the definition of a special generation, a suitable generation/simulation field has to be active in the Basic Mode Window. If a generation/simulation is not started, select D/Menu and either A/Window 1 Setup or B/Window 2 Setup to configure a generation/simulation. For more information on how to configure a generation/simulation, see chapter Generating/Simulating on page 58 and its subchapters.

Notes. Only one of the special generations may be active at a given time. Special generations are available only in Basic Mode.

Note that because of the Starting point setting, the first repeat of the leftmost example is limited to a small starting step and only two full steps. Generally: if the stepping settings limit the first repeat to only a fraction of a full repeat it is still calculated as one repeat.

You may enter either the Step Size or the

Number of Steps. Because these values

depend on each other, the value of the other field is calculated whenever you make any changes. Also, you can only enter an integer as the Number of Steps value. If you

enter a step size that results in a non-integer value for the Number of Steps field, MC5 displays a dashed line instead of a value for the Number of Steps field. This indicates that the size of the step that reaches the 100 % range limit is smaller than the defined step size. See the rightmost example.

To stop stepping press the function key C/

Stop Stepping. This applies for both a con-

tinuous stepping (Repeats field set to zero) and a stepping with a predetermined amount of repeats (max. value 65535).

Data Logging

General

The Data Logging utility is a firmware option that allows you to collect data using MC5. The collected data may then be viewed, transferred to a personal computer (PC) and printed using a utility shipped together with MC5 if the Data Logging option is purchased.

The maximum amount of measuring channels can be up to seven (valid only if your MC5 includes a sufficient amount of measuring modules/ports).

Data Logging may be configured to collect data using different triggers and saving methods as described further on.

Configuring

To start configuring the Data Logging (starting from Basic Mode), press

D/Menu, C/Others, 5/Data Logging.

The upper part of the Data Logging configuration window is reserved for seven measurement channels and the lower part for general settings. The following subchapters describe how they are configured.

Assigning Measurement Ports to Channels

Move the cursor to one of the measurement channel rows in the Data Logging configuration window. Press C/Edit to open the following channel settings window: Select the measurement port first. The other settings depend on the port setting.

To clear a channel, select port None in the channel settings window. To remove all channel settings, select

D/Menu, 1/Clear All Channels in

Generating Signals Using External Devices

To be able to utilize devices connected to the auxiliary instrument interface (AUX) you need to have the required firmware option. The following paragraph explains how to activate MC5 to use a connected external device. The instructions are also valid when the connected device is changed.

To select an external device, open either Window 1 or Window 2 setup menu (select D/Menu and either A/Window 1 Setup or

B/Window 2 Setup in Basic Mode). Make sure the quantity setting

of the window corresponds to the external device’s quantity requirements. Continue to the third submenu by pressing the numerical

To be able to communicate with the external device, MC5 requires some additional data which you can enter in the window that opens automatically after you have selected the Controller Settings menu option. This is presented on the next page.

Advanced Operation and Configuration

Select the Controller Type. The list of available controllers varies depending on installed options and the selected quantity. The other settings vary depending on the

Controller Type setting.

Note. The Settings window for external

devices may also be opened from Calibration Mode’s Instrument window. Additional information on how to use external devices in Calibration Mode is in Part D chapter Us-

ing External Devices in Calibration Mode on page 118.

Controlling the External Device in Basic Mode

When an external device is configured for use, the device name is displayed in the window it was assigned to, e.g. POC4 in the adjacent picture.

Enter target values (setpoints) for the connected external device in the numerical field following the device name.

Pressure Controller Settings

The following pressure controllers were supported when this User Guide was written:

• Beamex POC4 and

• Druck DPI510 equipped with the RS232 communication op-

tion (only gauge pressure type models).

• Druck DPI 515

The following settings apply in general to all supported pressure controllers. If certain controllers have device specific data, it is mentioned in the general description.

Advanced Utilities

Control Mode

Possible settings: Shut Off and Continu-

ous.

Shut Off means that the Pressure Controller shuts down after the desired pressure level is reached. When Continuous is selected, the Pressure Controller is active all the time. Even after the setpoint value is reached.

The first method is to be preferred because it minimizes the amount of disturbances in the system, provided there are no notable pressure leaks in the system.

Note. Although the pressure controller does measure the generated pres-

sure, it is not passed on to MC5 in MC5’s Basic Mode. Therefore you should always connect the generated pressure also to a pressure measurement module in MC5.

When a controller is used in Calibration Mode, Input Mode “Con-

trol” is used when the instrument’s input signal is measured with

MC5 and Input Mode “Ctrl/Mea” when the controller communi- cates the generated pressure to MC5.

Zero the pressure controller using its own user interface or program it to zero itself every time it generates zero pressure.

Device Address

Device address is needed if the Pressure Controller is in addressed mode. Addressed mode also allows daisy-chain connecting several Pressure Controllers.

Serial communication settings

The communication settings shown in the window are the ones required by MC5. The settings vary depending on the connected pressure controller (usually the default communication settings of the pressure controller). If the settings have been changed afterwards, refer to the pressure controller’s manual on how to change the communication settings.

Advanced Operation and Configuration

Temperature Controller Settings

The following temperature controller manufacturers have models that communicate with MC5 (the list was valid when this User Guide was written):

• TekKnow,

• Isotech,

• Ametek/Jofra SE, ATC, CTC and ITC models and

• HART Scientific, most Industrial Models.

When in doubt whether your controller type or model communicates with MC5, contact Beamex support. E-mail: support@beamex.com or use the contact info available on the prepages of this manual.

The following settings apply in general to all supported temperature controllers. If certain controllers have device specific data, it is mentioned in the general description.

Device Address

The Device Address of TekKnow TC1200 and Isotech is either 1 or 2, depending on the device configuration.

The Device Address field is not visible for temperature controllers that do not need the setting.

Note. Although the temperature controller does measure the tempera-

ture of the bath/dry block it is not passed on to MC5 in MC5’s Basic Mode. Therefore it may be of use to also connect a temperature sensor to a suitable port in MC5.

When a controller is used in Calibration Mode, Input Mode “Con-

trol” is used when the instrument’s input signal is measured with

MC5 and Input Mode “Ctrl/Mea” when the controller communicates the temperature to MC5.

Serial communication settings

The communication settings shown in the window are the ones required by MC5. The settings vary depending on the connected temperature controller (usually the default communication settings of the temperature controller). If the settings have been changed afterwards, refer to the temperature controller’s manual on how to change the communication settings.

Printing

Advanced Utilities

When using the optional printer you may print out screenshots of any user interface screen (e.g. calibrations results) in MC5.

You can print the screenshot by pressing the key simultaneously. MC5 responds with a long beep to indicate that the screen is dumped to the printer.

The printer can not be used at the same time as MC5 is connected to a computer because the printer and the computer uses the same interface (the COMP/PRT connector).

Notes. If you press the

Additional 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 in 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 quantity and port in MC5. 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 user need not jump to read this supplemental text, but for a beginner we highly recommend it.

The main subjects described here are:

Things to Consider when Measuring Pressure on page 95, Thermocouple Measurement/Simulation, Connections and Troubleshooting on page 97, Resistance and RTD Measurement, Connections on page 101 Current Measurement Parallel to a Test Diode, Connections
