8.2 Do Not Modify Or Disassemble

 Do not use the apparatus for jobs other than those for which it was designed, i.e. the

calibration of thermometers

 There are no user serviceable parts inside. Do not dismantle or modify the apparatus. For

repair information contact Isothermal Technology Ltd

 For equipment with fans, the fan should kept free from dust build up; a soft brush or

vacuum cleaner may be used on the external grill

8.3 Beware Of Electrical Considerations

 The equipment is for installation category II (transient voltages) and pollution degree

II in accordance with IEC 664 at altitudes to 2000 metres

 Sensor Input Connection must never exceed 30V with reference to ground
 Thermostat test inputs should be voltage free: isolate from any voltage source during test

8.4 Be Careful Where It Is Used

 The equipment is not for use in hazardous areas or in an environment close to flammable

materials or gases

 The equipment must be used on a flat level surface, with adequate space around it for air

flow and avoid blocking ventilation slots

 Ensure free space above the unit to avoid risk of burn or fire
 The equipment should only be used indoors
 Site in a way that allows access to the power switch, and to allow the cable to be

disconnected

 Avoid excessive heat, humidity, dust and vibration ensuring it will not be subjected to

dripping or splashing liquids

8.5 Be Careful With Extremes Of Temperature

 In normal use the calibration volume, inserts and probes will become very hot and present

a burn hazard

 Do not remove inserts, probes or handle the equipment when it is hot or cold.
 Allow the equipment and accessories to reach a temperature between ambient and 70°C

before switching off or storing the equipment in its case

 Do not use the equipment outside its recommended temperature range
 Operating the equipment at extremes of temperature for extended periods may call for

early replacement of the heating assembly

 Wear appropriate protective clothing

8.6 Be Careful With Inserts

 Only use inserts supplied with, or ordered specifically for, this model
 Do not handle inserts while they are very hot or cold
 Inserts for low temperature models may melt and cause a fire if used in high temperature

models

 Only use Isotech inserts which are specially treated to avoid them from becoming stuck in

the calibration volume

 Do not use powders, liquids or compounds in the insert; this may lead to the insert or

probes becoming stuck

13

8.7 Be Careful With Fluids

 Isocal-6 models can be used as liquid baths; the Hyperion and Drago models can have the

liquid directly in the block or the liquid container. For all other models do not add liquid
directly to the block; you must place the liquid in the appropriate Isotech liquid container
kit.

 To avoid risk of toxic fumes or ignition only use the appropriate fluid and be careful not to

exceed the stated temperature range

 Do not handle hot fluids
 Wear appropriate eye protection and be careful to avoid spills, overspills or splashing
 Do not overfill - liquids will expand on heating, allow room for expansion
 Be careful to select an appropriate liquid – viscous liquids will offer poor thermal

performance.

 Never mix fluids and keep containers clean and dry before introducing a new fluid
 Do not use oils below the dew point. Water introduced into oil can present a hazard at

higher temperatures due to steam generation

 Ensure adequate ventilation of any liquid fumes

9 Consider The Environment

The equipment should be recycled or disposed of in a proper way; following the Waste
Electrical and Electronic Equipment (WEEE) directive

15

10 Introduction

The Isocal-6 range of products allows unprecedented flexibility for the calibration of temperature
sensors. The Isocal-6 range may be used with the following options:

1. As a Metal Block Bath

2. As a Stirred Liquid Bath (not Drago)

3. A Blackbody Source

4. A Surface Sensor Calibrator

5. An ITS-90 Fixed Point Apparatus

10.1 Comparison Calibration

By definition, one compares industrial thermometers to a calibrated standard. There are three
methods commonly used.

10.2 Basic Operation

Using the controller as the “calibrated standard”. This method means that the

complete bath is calibrated by comparing the controller reading to a calibrated
standard placed in the bath.

This is a common method but is unsafe since the control sensor is

a) inaccessible
b) in the wrong place to give correct temperature of the insert

For these reasons it fails to satisfy ISO9000 and gives large uncertainties.

10.3 Site or Self-Contained Calibrators

In these an indicator and external calibrated sensor are used to measure
the temperature of the insert. This arrangement gives good results and
traceability. To recalibrate however it does mean sending the whole
calibrator back to the calibration laboratory. The calibrator is self­contained, self-sufficient and meets ISO9000 requirements.

16

10.4 External Standards + Basic

Here a separate indicator and calibrated sensor
are used to measure the inserts temperature.
With a suitable indicator such as the Isotech
milliK this gives the most accurate and reliable
results, depending on the indicator.

It means that the calibrator does not need
calibrating; only the indicator and its calibrated
sensor need re-calibration. One indicator may
be used with a range of blocks. This method
also meets ISO9000 requirements.

10.5 ADVANCED Calibrators

The ADVANCED model includes an indicator with channels for both
the test thermometers and an external calibrated sensor used to
measure the temperature of the insert. This allows best practice
calibration with established traceability and uncertainty. To
recalibrate however it does mean sending the whole calibrator back
to the calibration laboratory. The calibrator is self-contained for
reference and test probes, self-sufficient and meets ISO9000
requirements.

17

11 Mode Of Operation

11.1 Metal Block Bath

The metal block bath function of the Isocal-6 is well suited for fast, convenient,
mess free calibration of temperature sensors.

The Isocal-6 metal insert is placed into the calibration well. The stir speed control
should be set to the OFF position (turn fully anti-clockwise).

The thermometers under test are placed into suitable holes in metal. For the
ADVANCED and Site models a calibrated reference probe should be placed into
the insert and the actual temperature can be read from the unit’s display. For the
Basic models an external temperature indicator should be used.

For traceable calibration the actual value of the insert temperature should be
recorded along with the values from the sensors under test.

11.2 Stirred Liquid Bath

The stirred liquid bath function of the Isocal-6 is well suited for odd shaped sensors
which will not easily be accommodated in a metal insert.

Liquid baths have the added benefit of potential for greater accuracy due to better
temperature uniformity and the avoidance of air gaps.

The liquid can be placed directly into the block. Take care not to spill any liquid
and remove the mains power connector during filling. Placing the liquid directly
into the block will provide the fastest response time and best agreement between
the temperature of the oil and that indicated on the temperature controller. Take
care not to overfill and allow room for the liquid to expand as it is heated. The
maximum depth should be approximately 150mm.

Liquid containers can be used and will be particularly useful when more than one
liquid type is to be used. Using one container for each liquid permits rapid mess free change of
fluid.

The Isocal-6 Liquid Container is placed into the calibration well and the container is filled with a
suitable liquid, for the temperature range that the bath is to be used over. The container should
be filled to 40mm from the top of the tank. Care must be taken to adjust the level as the liquid
contracts or expands with temperature changes. The stirrer speed control is set ON and to the
mid position. If necessary the speed to can be adjusted to give the optimum value for a particular
application, this position should be found experimentally and then noted for future use.

The thermometers under test are placed into the liquid. Two accessories are available to support
the thermometers.

a) The Thermometer Support - this sits into either the calibration volume or the liquid

container. The thermometers rest against the suspended lower plate.

b) An optional cap is available which grips the thermometers; suspending them into the

liquid. The cap has two diameters and can be fitted to the block or to the liquid container.

18

It is important that one of the accessories is used to prevent the probes from reaching the bottom
of the tank which would stop the stirring action. For the ADVANCED and Site models a calibrated
reference probe should be placed into the liquid and the actual temperature can be read from the
unit’s display. For the Basic models an external temperature indicator should be used. For
traceable calibration the actual value of the liquid temperature should be recorded along with the
values from the sensors under test.

11.3 Stirred Ice Bath - Hyperion Model Only

The Stirred Ice Bath function is as the Stirred Liquid Bath. The liquid container is filled with water,
the stirrer speed control set to mid-position and the controller set to 0.0°C. Once the controller
has stabilized at 0.0°C allow 10-15 minutes before starting calibration.

11.4 Black Body Source

The black body function of the Isocal-6 is well suited for fast, convenient,
mess free calibration of infra-red temperature sensors.

The Isocal-6 black body target is placed into the calibration well. The stir
speed control should be set to the OFF position.

The units under test should be aligned with the target.

For the S models a calibrated reference probe should be placed into the
hole in the block and the actual temperature can be read from the
temperature indicator to which the infrared thermometer(s) are
compared. For the B models and external temperature indicator should be
used.

11.5 Surface Sensor Calibration

The surface sensor function of the Isocal-6 is well suited for fast, convenient,
mess free calibration of most surface temperature sensors.

The Isocal-6 surface sensor insert is placed into the calibration well. The stir
speed control should be set to the OFF position.

A calibrated probe s placed in the pocket of the surface sensor insert and
connected to the temperature indicator of the S models. For the B models an
external indicator should be used. Surface sensors are placed on top of the
insert and when stable compared to the calibrated probe.

11.6 ITS-90 Fixed Point Calibration

The ITS-90 fixed point function of the Isocal-6 is well suited for fast, convenient, mess free
calibration of thermometers to uncertainties as low at 0.001°C.

The special cell is placed into the Isocal-6 calibration well. The stir speed control should be set to
the OFF position. For detailed operating information, refer to the separate manual provided with
the cell

19

12 How To Measure The True Temperature Inside The Accessories

Supplied With The Isocal-6

The controller of the Isocal-6 controls and reads the temperature of the block surrounding the
35mm∅ by 160mm deep calibration well.

There are various accessories including the surface calibration insert, the oil container, blackbody
etc. These adapt the Isocal-6 to perform varied calibration functions.

None of these accessories actually get to the block temperature (and hence the controller’s
temperature) because each accessory has a different immersion characteristic. For this reason the
Isocal-6, like all comparison baths, requires a reference thermometer to indicate the true
temperature inside the accessory.

Remember the following:-

12.1 The Controller

The controller is used to set a constant temperature and create an isothermal environment for the
comparison calibration of temperature sensors.

12.2 The Reference Thermometer

The reference thermometer is placed in the accessory or insert and measures the true temperature
inside the insert or accessory.

12.3 The Industrial Thermometer

The industrial thermometer is placed in the accessory or insert and is compared to the true
temperature as indicated by the reference thermometer. An insert will typically have a 1%
immersion error. For more details see - Depths of Immersion. Tavener J. P – available at
http://www.isotech.co.uk

15.7 Thermostat testing using the ADVANCED unit

The ADVANCED equipment has the facility to test thermostats or thermal switches using the page
featured in figure 4. Up to two thermostats can be tested at the same time.

The system uses Channel 1 as a reference channel to record the temperature of the thermostat
opening or closing. To use this feature, there must be a thermometer connected to Channel 1.

The sense of the thermostat can be changed by the user and each thermostat is referred to as
“FREEZE 1” and “FREEZE 2”. The options are Normally open (N/O) or Normally closed (N/C).

The thermostat is connected via the 2mm input sockets on the controller plate (item 9, figure 1).

You are not required to log in to access this feature.

How to change the SENSE value on the FREEZE display:

1. Scroll to the FREEZE display page

2. Highlight SENSE 1 by pressing the SCROLL button

3. Press the SCROLL button again to access the value and adjust using the up/down buttons

4. Enter the value by pressing the SCROLL button again

5. To adjust SENSE 2, scroll the it at point 2 and adjust as above

Note: if there is no sensor connected to Channel 1 the FREEZE display will return an
“ERROR” message.

29

15.8 Enabling The AUTOTUNE Feature

Note: This feature is available on all ADVANCED equipment except PEGASUS.

The ADVANCED equipment has the ability to AUTOTUNE the control parameters to hone the
temperature stability at a specific block temperature. When enabled it will allow the controller to
cycle the temperature of the block and calculate the best values for this temperature. After two
cycles it will install the calculated values and use these for the control loop.

You are not required to log in to access this feature.

To enable the AUTOTUNE feature:

1. Scroll to the USER ACCESS page

2. Press the Scroll button and then select the AUTOTUNE feature using the down button

3. Press the Scroll button again to highlight the feature

4. Use the up/down button to select ON

5. Press the Scroll button again to enter the value.

6. The controller will now begin the tuning process

During the tuning process, AT can now be seen to the left of the clock on the ISOTECH homepage
(figure 3).

To disable the tuning feature during a tune, repeat the process above and select OFF. This will
now disable the tune and install the previous values.

15.9 Using the SETPOINT TRIM feature for Offset Elimination

This ADVANCED equipment has the facility to adjust the heat source temperature to a value
determined by Channel1 temperature sensor (only Channel 1 will function with this feature).
This allows the user to more accurately bring the block temperature closer to the reference
temperature without making any manual adjustments. This value will automatically adjust every
30 minutes and will not adjust to any value outside of ±5°C of the control sensor value. This will
prevent overheating in the event of a sensor failure of the sensor being accidently removed from
the heat source. In this event the equipment will disable the feature and control in normal mode.

You are not required to log in to access this feature.

To enable the SETPOINT TRIM feature:

1. Ensure a reference sensor is connected to channel 1 and fully immersed into the heat

source

2. Scroll to the USER ACCESS page and scroll down to the SETPOINT TRIM box

3. Press the Scroll button to highlight the feature

4. Press the up/down button to change the value to INPUT 2

5. Enter this with the Scroll button

6. Exit by pressing the PAGE button and scroll to the homepage

The display may change by the difference between the reference temperature and the control
sensor value. This is normal and should not be adjusted.

To exit SETPOINT TRIM mode repeat the process above and enter INPUT 1 and the controller will
now function in normal mode.

15.10 How to change the Date and Time or the Language of the

ADVANCED equipment

The Date and time of the ADVANCED equipment can be changed to suit local time. This can also
incorporate the any daylight saving time in the time zone of your country or region. The display
language of some of the display screens can also be change to suit the local language.

The options for this are:

 English
 French
 German
 Italian
 Spanish

Note: Only the Supervisor and Engineer menus will read in the alternative language. The Isotech
Home screen will still read in English when this feature is used.

To change the DATE and TIME or LANGUAGE:

 To access these features you will need to log in as the Engineer.
 When logged in, scroll to the INSTRUMENT tab on the Engineer homepage
 Press the SCROLL button to enter
 Scroll to CLOCK and enter by pressing SCROLL button
 Alternatively scroll to LOCALE and enter by pressing SCROLL button
 Adjust as necessary and exit engineer mode

15.11 Thermometer Input Channels

The ADVANCED equipment has three temperature sensor input channels that can be used for
either a Platinum Resistance Thermometer or a Thermocouple. Channels 1 and 2 can accept
either of these sensors or Channel 3 can accept a Thermocouple.

The thermocouple input connectors used on all three channels have internal cold junction
compensation. This means that the thermocouple can plug directly into the Copper connector
and the controller will automatically compensate for the cold junction of the thermocouple. Ensure
the thermocouple has no additional cold junction as this will introduce errors.

Each of these channels can accept up to eight correction points to improve the linearity of the
thermometer accuracy to the Controller display. These are user defined and are unique to only
one thermometer.

When using the calibration feature, the points must be used in ascending order, that is to say, the
lowest point (Point 1) must be used at the lowest temperature. Each point for the calibration is
based on two values: the temperature at which the value is applied (the point) and the value to
adjust the temperature by (the offset). The factory default setting for each unused channel is
Point -200 and Offset 0.00. This means that if the calibration is enabled then the controller will
ignore these values until they are populated with real values.

The feature functions in the same way irrespective of sensor type.

31

The calibration (CAL STATUS) has several settings listed below:

POINTS 1-8: The specific values that are entered to calibrate the thermometer to the controller

ON: Enables the calibration and allows the adjustment of the populated points to function

OFF: Disables the calibration and the channel runs unadjusted

RESET: Erases all existing data for all points (Care must be taken with this as this is not reversible)

15.12 Process to apply a User Calibration to the controller using a PRT

connected to Channel 1

1. Connect the thermometer to Channel 1 and ensure the channel is correctly configured

using the processes above

2. Ensure the thermometer is correctly inserted to heat source of the ADVANCED equipment

3. Ensure the Calibrated Reference thermometer is placed in the same heat source

4. Allow the system the thermally stabilise

5. Press the PAGE button to enter the SUPERVISOR menu

6. Scroll to the CHANNELS tab and enter with the SCROLL button

7. Select 1 from the list and enter with the SCROLL button

8. Scroll to the ISOTECH tab and enter with the SCROLL button

9. Scroll to CAL STATUS and enter with the SCROLL button

10. Scroll to POINT 1 and enter

The controller is now ready to accept a value. Ensure the equipment is thermally stable, you will
now need to use the temperature value displayed by the Calibrated reference thermometer.

11. Record the value on the Calibrated thermometer and scroll to DISPLAY VALUE tab and

press enter

12. This will bring up a soft keyboard, use this keyboard to enter the exact temperature

displayed by the calibrated standard

13. Press the PAGE button to enter the value, the controller will ask you to confirm the settings.

Select YES and enter the value

14. The controller will now accept the value and move to POINT 2 on the display

15. Exit back to the homepage and check the value on the CHANNEL 1 display window

16. When confirmed, move to the next temperature and repeat the process for point 2 and so

on

This process is the same for all three channels.

32

15.16 Data Logging

The ADVANCED equipment will always record data for all four channels UNLESS the equipment is
in ENGINEERING mode. This is indicated by the green R in the bottom left had side of the

ISOTECH homepage (figure 3).

The data can either be extracted via the USB socket on the front panel or to a PC by means of
the FTP protocol (Remote Archiving) using REVIEW software.

To back up the data via USB stick on the control panel use the following procedure:

1. Log in as the SUPERVISOR

2. Plug a suitable USB memory stick (8GB maximum) to the socket on the control panel

(figure 1, item 6)

3. Ensure the controller has accepted the memory stick by the icon in the lower left of the

ISOTECH homepage (figure 3)

4. Press the page button to scroll to the SUPERVISOR menu

5. Scroll to DEMAND ARCHIVING

6. Scroll to ARCHIVE TO and enter, select USB from the options and enter

7. Scroll to ARCHIVE and select from:
a. Bring to date

34

b. All
c. Last month
d. Last week
e. Last day
f. Last hour
g. None

8. When the selection is entered by pressing the SCROLL button, the transfer will begin (this

may take several minutes depending on the selection made)

9. When the transfer is complete, remove the USB stick and exit SUPERVISOR mode

The data will be stored in a folder called HISTORY.

15.17 FTP Server Archiving

This allows the archiving of recorder files to a remote computer via the RJ45 type connector at
the rear of the recorder, either directly or via a network.

In order to carry out a successful transfer:

1. Details of the remote host must be entered in the Network Archive area of configuration

2. The remote computer must be set up as an FTP server. Help from the user’s IT department

may be necessary in order to achieve this.

3. The remote computer must also be set up to respond to ‘pings’. This is because the

instrument pings the host whilst establishing connection, if it does not receive a response
the archive attempt fails.

4. When accessing files using Microsoft® Internet Explorer, the address (URL) field can be

in one of two for-mats:

5. ftp://<instrument IP address>. This allows a user to log in as the anonymous user (if the

recorder has any account with the user name set to ‘anonymous’ with a blank password.

6. ftp://<user name>:<password>@<instrument IP address> to log in as a specific user.

For IE5 users, Microsoft® Internet Explorer displays, by default, history files only. To quit the

history folder, either uncheck the Tools/Internet Options/Advanced/Browsing/’Enable folder view
for FTP sites’ option, or check the Tools/Internet Options/Advanced/Browsing/’Use Web based
FTP’ option.

15.18 Programmer Function

The ADVANCED equipment has an on-board PROGRAMMER function built in. The PROGRAMMER
runs in SEGMENTS and can store up to 100 programs, each containing 25 segments.

This feature is particularly useful for an automated calibration run, the test data can then be
extracted and converted to a spreadsheet using the REVIEW software available.

The programs can either be created using the available software, or using the control interface
on the ADVANCED equipment.

The software can be downloaded at www.isotech.co.uk/downloads. Once created, a program can
be sent directly to the instrument via the network connection or saved to a USB memory stick and
imported from there via the USB socket on the controller panel (Fig1, item6).

10. Both the original file and the modified file will now exist in the memory

15.23 Using the HOLDBACK feature

The PROGRAMMER has a HOLDBACK feature available.

Holdback pauses the program (freezes the Programmer setpoint (PSP) and the time remaining
parameters) if the difference between the Process value (PV) and the PSP exceeds a user-specified
amount (Holdback value). The program remains paused until the PV returns to within the specified
deviation.

In ramp or step segments, holdback indicates that the PV is lagging the SP by more than the
specified amount and that the program is waiting for the process to catch up. In a dwell segment,
holdback is used to guarantee that a work piece stays at set-point within a specified tolerance for
the specified dwell duration.

39

This is particularly useful when running a calibration program as it will allow the heat source to
eliminate any “lag” between the controller and the heat source itself.

Holdback can be configured to hold either the segment or the complete program.

The USER defined value is used to define the actual value applied to it.

This can either be:

LOW, where the heat source temperature is below the Setpoint. The programmer will hold the
value until the heat source has “caught-up” in temperature.

HIGH, where the heat source temperature is above the Setpoint. The programmer will hold the
value until the heat source has “caught-up” in temperature.

BAND, where the heat source is outside a band of temperature around the setpoint

To enable this feature

1. Go to EDIT AN EXISTING PROGRAM and enter the menu

2. Scroll to HOLDBACK STYLE and enter using the SCROLL button

3. Select desired parameter and enter using the SCROLL button

4. Scroll to CH1 HOLDBACK and enter the desired parameter and enter with the SCROLL

button

5. Scroll to CH1 HOLDBACK VAL and select the desired temperature, enter using the SCROLL

button

18 Connecting to a PC

There are several software applications that can be used with the ADVANCED models

18.1 Isotech Config Utility

This application makes it easy to adjust and set the various options such as sensor input types,
units, resolution etc.

45

18.2 Isotech I-Cal EASY

This application allows logging of data from the ADVANCED model. Additionally if a license is
purchased it allows for fully automatic calibration including certificate printing and the calculation
of coefficients.

Refer to the Isotech I-Cal EASY handbook and help system for more details

18.3 Program Editor

This allows set point programs to be created on a PC and uploaded to the ADVANCED model

Installation instructions are included with the download

46

18.4 Review

This is a proprietary software package which allows the user to extract ‘archive’ data from one or

more ADVANCED Dry Blocks and to present this data on a host computer, as if on a chart, or as
a spreadsheet.

As described in the Review help system, ‘Review’ allows the user to set up a regular transfer of
data (using ftp) from connected instruments into a database on the pc, and then from this
database to the chart or spreadsheet. The chart/spreadsheet can be configured to include one
or more ‘channels’ from one or all connected instruments.

It is also possible to archive instrument history files to a memory stick and to use this to transfer
the data to the pc.

The user name and password are both ‘history and they are not editable.

These applications can be downloaded from the Isotech website

http://www.isotech.co.uk/downloads

Connection to the unit is via the Ethernet interface, configure the IP address to suit your network
and then select that IP address in the software. Consult your network manager for assistance if
required.
