Introduction

Congratulations for selecting the ultimate calibration tool!

CL560 is a documenting All-In-One Multifunction Calibrator with cali­bration capability of pressure, temperature, electrical and frequency
signals. CL560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 CL560 that previously only included pressure
modules.

Thanks to the logical user interface CL560 is very easy to use. The
large backlit graphical display guides the user in different languages
and it displays results both numerically and graphically.

CL560 performs automatic calibration of pressure, electrical and
temperature process instruments. It is capable of communicating
with external devices such as pressure controllers. CL560 also com­municates with HART field instruments.

CL560 represents the state of the art in accuracy, adaptability and
all-round usability.

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
CL560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

CL560 in this manual) has an example configuration of modules.
The configuration of your CL560 may vary significantly from the
one in the picture.

4

The Upper Panel

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

External Pressure Modules

CL560 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 CL560.
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 CL560 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.

General

The Connectors on the Left Side of CL560

The left side of CL560 (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 CL560 or, e.g. a software that reads data log­ging results in CL560 and transfers them to a PC.

The same connector can be used when CL560 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 CL560
to a PC or a printer.

Auxiliary Instrument Interface

The AUX connector is used when connecting pressure controllers,
temperature baths/dry blocks etc. to CL560.

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

6

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, cur­rent 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.

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 CL560
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
CL560 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 CL560 and the correct reference junction settings
as well as the reference junction temperature have to be informed
to CL560.

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

Keyboard

CL560 Hardware

The keys on the CL560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 CL560 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 CL560.

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

key or use the D/OK

Memory

10

CL560 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 CL560 can maintain in its memory. It all depends on how much
memory is allocated by other data.

Batteries

Full batteries:

Empty batteries:

CL560 Hardware

CL560 supports the use of both rechargeable batteries and alka­line batteries. When using alkaline batteries, you need a Dry Bat­tery Cartridge. CL560 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 CL560s Base Unit. If you have two sets of rechargeable bat­teries you may charge the disconnected Battery Pack while at the
same time use CL560 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 CL560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.

CL560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
CL560 is not in use.

Do not leave CL560 without a Battery Pack or a Dry Battery Car­tridge for a long time. CL560 may loose its settings if it is left without
a support voltage for an extended period.

11

General

About the Charger and the Charging Procedure

The charger is connected to the charger connector at the bottom of
CL560. The charging electronics informs you of the phases of the
charging procedure with the help of the charge status light.

C h a r g e r c o n n e c t o r

C h a r g e s t a t u s l i g h t

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). CL560 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

12

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 CL560 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.

CL560 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.

13

General

Support for Table Top Use

The support gives you a good viewing angle when CL560 is placed
on a table top. Lift the support at the back of CL560 and place
CL560 on the table top as shown in the picture.

The Wrist Strap and the Neck Support Strap

CL560 has a wrist strap to enable ease of use
when CL560 is held in one hand. The neck
support strap helps you during field calibra­tion: Position CL560 in an angle that allows
reading the display when working. Alterna­tively: Hang CL560 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

CL560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.

14

CL560 Firmware

CL560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 CL560.

General Description

The following picture shortly describes the functions of the firm­ware. All main functions are marked with a black border. Each main

Startup Procedure

The following chapters briefly describe each main function.

Every time CL560 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 CL560 automatically proceeds to Basic Mode. A more
comprehensive description of the Startup Procedure is in the be­ginning of Part B of this manual.

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 CL560 (requires a
password).

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

CL560s main duty is calibrating instruments. Therefore very spe­cial attention was directed on this matter when creating the calibra­tor. CL560 may be used as a stand-alone calibrator i.e. all instru­ment data and calibration history data is saved in CL560s own
memory. Optionally CL560 also communicates with calibration soft­ware.

CL560 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

16

The graphical representation as well as numeric data of the calibra­tion results may be viewed in CL560 (and printed if the optional
printer is available). Transferring the results to a 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 User Interface

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 (
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 CL560.

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.

Calibration:

The display area is divided into
three windows during a calibration.

The first window displays data re­lated to the instruments input sig­nal. The second corresponding
data related to the output signal.

The third window displays the er­ror graph. The error graph is also
seen among calibration result data.

Configuration Window:

There are plenty of configuration
windows in CL560. The picture be­side is the configuration window for
Ramping settings.

CL560s Modularity and Options

25

General

Safety

CL560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 CL560s case withstand normal industrial condi­tions. CL560 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)

CL560 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

CL560 calibrator is a precision calibration tool that should be used
by skilled people. Working with CL560 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 CL560 only if you are certain of that it can be used safely. Safe
use of CL560 is no longer possible if one or more of the following
cases are true:

· When the case of CL560 is evidently damaged

· When CL560 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 CL560 battery charger in a non-hazardous indoor loca­tion only and only with this calibrator.

Only use the printer that is available as an option. Using any
other printers may damage the printer or CL560 or even both
of them.

CL560 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

27

General

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

The measurement and generation terminals of CL560 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 CL560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 CL560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 CL560 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
CL560. 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.

28

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.

Service

Firmware Update

General

Only qualified service personnel may perform higher level mainte­nance for CL560. Never open the case unless have explicit in-
structions from Omega or a local representative.

There are, however a few things that anyone using CL560 may do.

The quickest way to see if a new firmware version is available is
checking out Omegas web site. Go to the Downloads page and
see what it says about CL560 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 CL560, using e.g. a
calibration management software. Also check for possible release
notes accompanying the updated file.

Recalibrating MC5

The Battery Charger

30

Contact Omega or your local representative for information con­cerning the recalibration of CL560.

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 CL560 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 CL560 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.

Basic Mode, Defined

Every time CL560 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 CL560 works like
a high quality multimeter. When returning from CL560’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 CL560’s modularity you may or may not have the
required module. If the module is not included in your CL560, 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 CL560’s terminals, like the one below.

Limit Switch Test

A limit switch test displays the opening and closing point of a limit
switch. CL560 supports limit switch testing of any type of limit
switches as long as CL560 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 CL560 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 CL560.

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

@” data is updated as the switch changes

its state.

greatly on the change rate of the switch’s input signal.

Hint.
If you use CL560 to generate/simulate the switch’s input signal,

you can use ramping to create changing input signals for the switch
under test.

Special Measurements

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.

to open the submenu.

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.

To zero/restart a special measurement without altering any main
measurement settings, do the same menu commands you used for
starting the special measurement.

Generating/Simulating

General

This chapter and the subchapters describe only how to generate/
simulate signals using CL560’s own modules. Part C discusses the
use of external devices connected to the auxiliary interface.

CL560 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 CL560’s modularity you may or may not
have the required module. If the module is not included in your
CL560, the 1/Quantity and 2/Function/Port settings needed for
the generation/simulation are not available as choices in the pop­up lists.

Each generation/simulation also has at least one picture with a circle
around some of CL560’s terminals, like the one below.

Generating/Simulating

Warnings!
When selecting a generation/simulation function, CL560 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 CL560, 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

The voltage between the output connectors of the ET module is
limited to ±15 Volts. There is no sinking possibility in the ET mod­ule.

Using the E module’s output

Generating/Simulating

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, CL560 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 CL560. If you simulate a thermocouple in
millivolt mode, you must convert from temperature to millivolts manu­ally.

Warning!
If you short circuit the voltage output, CL560 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

CL560 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. CL560 con­trols the voltage across its terminals so that the resistance (voltage to current ratio) cor­responds to the simulated temperature or resistance. CL560 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 CL560

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

CL560 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 CL560. To the instrument under test CL560 appears
as a thermocouple at the given temperature.

Thermocouple simulation terminals are located in the ET module.

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 CL560. 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 CL560’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, CL560

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.

Special Generations

Manual change of generated signals is sometimes a restriction.
Therefore CL560 includes Stepping and Ramping as standard utili-
ties 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,
CL560 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

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

Note.
CL560 actually makes the ramp in small steps. The steps are as

small as possible, slower ramps use smaller steps.

Display Mode Settings

By default, CL560 displays all mea­surement, generation and simula­tion data in engineering units. In
Basic Mode you can also select
some special Display Modes. To
change the Display Mode, select
the Window setup menu (Com­mands: D/Menu and B/Window 2

Setup, if needed) and choose
3/Display Mode.

All of the available special Display
Modes are described in the subse­quent chapters.

All special Display Modes are reset to Engineering Units Display

Mode if the quantity or port of the window(s) assigned to the special
Display Mode are changed.

Warning!
Be careful not to mistakenly read a value shown in special Dis-

play Mode as a value shown in Engineering Units. CL560 al­ways displays the true measurement in the window’s lower­most row (Extra Info row) when a special Display Mode is ac­tive.

you can select whether you want
to simulate a transmitter or a
switch.

Note.
To be able to start the Transmitter/Switch Simulation, both Ba-

sic Mode windows need to be configured accordingly. If, e.g.
window 2 is not assigned for generating/simulating a signal,
CL560 can not start transmitter simulation.

Function until the saturation limit is reached. Then if the input signal
drifts farther from the input range, the output value stays at the satu­ration limit.

The upper right picture shows the Basic Mode window while Trans­mitter Simulation is active. The second row of both windows display
the active port and the input/output range of the simulated transmit­ter.

Notes.
To Zero a pressure module during Transmitter Simulation, press

D/MENU and 7/Zero Pressure Module.

When pausing the Transmitter Simulation, you can change the gen­eration/simulation signal as in Basic Mode.

Warning!
Remember to scale the output signal of the Transmitter Simu-

lation so that the instrument connected to the output signal
loop is not damaged.

Data Logging

General

The Data Logging utility is a firmware option that allows you to col­lect data using CL560. The collected data may then be viewed,
transferred to a personal computer (PC) and printed using a utility
shipped together with CL560 if the Data Logging option is purchased.

The maximum amount of measuring channels can be up to seven
(valid only if your CL560 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

the Data Logging configuration win­dow.

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 CL560 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

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.

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.

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

sure, it is not passed on to CL560 in CL560’s Basic Mode. There­fore you should always connect the generated pressure also to a
pressure measurement module in CL560.

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

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

CL560 and Input Mode “Ctrl/Mea” when the controller communi­cates the generated pressure to CL560.

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 CL560.
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.

92

Advanced Operation and Configuration

Temperature Controller Settings

The following temperature controller manufacturers have models
that communicate with CL560 (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 CL560, contact Omega’s support.

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 CL560 in CL560’s
Basic Mode. Therefore it may be of use to also connect a tempera­ture sensor to a suitable port in CL560.

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

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

CL560 and Input Mode “Ctrl/Mea” when the controller communi­cates the temperature to CL560.

Serial communication settings

The communication settings shown in the
window are the ones required by CL560.
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.

93

Printing

Advanced Utilities

When using the optional printer you may print out screenshots of
any user interface screen (e.g. calibrations results) in CL560.

You can print the screenshot by pressing the
key simultaneously. CL560 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 CL560 is con­nected to a computer because the printer and the computer uses
the same interface (the COMP/PRT connector).

Notes.
If you press the

serial port is unavailable for PC communication for about a minute.
The printer is configured for communication with CL560 when de-

livered. If you inadvertently alter the configuration, please contact
Omega for instructions on how to restore the settings.

Advanced Operation and Configuration

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 CL560. 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:

Thermocouple Measurement/Simulation, Connections and
Troubleshooting on page 97,
