HANDBOOK

ISSUE 05 04/01

The Hyperion R has a large cavity designed for use as a black body whose temperature may
be set over the range -10 to 80C at an ambient of 20C.

The cavity is 50mm diameter by 150mm deep. The bottom is not flat but machined to have a
120 cone, see page 24.

A pocket is provided for an external thermometer which is used to measure the temperature of
the source. The reading from this thermometer should be compared with the pyrometer under
test if the greatest precision is to be realised.

Page 9 of 26

HYPERION R

HANDBOOK

ISSUE 05 04/01

OPERATION

The metal block, in which the cavity has been machined, has solid state heat pumps attached
which are used to heat or cool the block. These heat pumps or Peltier modules allow
temperatures below as well as above ambient to be realised. A platinum resistance
thermometer located in the block senses the temperature. The control system also includes
logic and switching for the heat pump’s DC power supply.

The temperature of the block is set by using the ‘ UP’ and ‘ DOWN’ keys of the temperature
controller. The lower display shows the target temperature or setpoint.

The heat removed from the block is dissipated into the forced air cooled heatsinks. It is
important that the air inlet and outlets of the Hyperion R are not obstructed.

For best results the temperature indicated on the controller should not be used for the cavity
temperature. A measurement system independent to the control loop should be used.

A 3 wire platinum resistance thermometer may be connected.

The temperature difference between this pocket and the target area of the cavity has been
determined to be less than 0.5C.

It is this measurement system that Isotech can calibrate and UKAS certify.

OPERATING THE CONTROLLER

FRONT PANEL LAYOUT

HYPERION R

HANDBOOK

ISSUE 05 04/01

The Temperature Controller

The controller has a dual display, the upper display indicates the nominal block temperature,
and the lower display indicates the desired temperature or setpoint.

Altering the Setpoint

To change the setpoint of the controller simply use the UP and DOWN keys to raise and lower
the setpoint to the required value. The lower display changes to indicate the new setpoint.

Advanced Controller Features

Setpoint Ramp Rate

By default the Dry Blocks are configured to heat (and cool) as quickly as possible. There may
be some calibration applications where it is advantageous to limit the heating (or cooling rate).

An example might be when testing bimetallic thermostats, by forcing the Dry Block to heat at
a controlled rate it is easier to determine the temperature at which the thermostat changes
state.

The Dry Block can have its heating rate limited with the Setpoint Ramp Rate feature. This
feature is accessed from the Scroll key. Depress the key until the display shows,

SPrr

Page 11 of 26

HYPERION R

HANDBOOK

ISSUE 05 04/01

On the Upper Display, the lower display will show the current value from OFF (default) to 999.9.
The desired rate is set here with the UP and DOWN keys, the units are C/min.

When the SPrr is active the controller display will show "RUN", the lower setpoint display will
now automatically update with the current value, known as the working setpoint. The setpoint
can be seen by pressing either the UP and DOWN key.

The Setpoint ramp rate operates when the bath is heating and cooling.

Instrument Address (Comms Models only)

The controller has a configurable "address" which is used for PC communications. Each
instrument has an address, this allows several instruments to be connected in parallel on the
same communications bus. The default value is 1. This address would only need to be changed
if more than one Dry Block is connected to the same PC port.

To check the Address value press the scroll key until the top display indicates,

Addr

The lower display will show the current value that can be modified with the UP and DOWN keys.

Monitoring the Controller Status

A row of beacons indicate the controllers status as follows,

OP1 Heat Output
OP2 Cool Output (Only for models which operate below 0C)
REM This beacon indicates activity on the PC interface

Units

Momentary pressing the Scroll key will show the controller units C or F.

ISSUE 05 04/01

The Temperature Indicator

The indicator can be configured for custom calibration data. The customer calibration data can
be set ON or OFF.

Enabling / Disabling Custom Calibration

Custom calibration allows the indicator to be programmed to suit a particular temperature
sensor. This allows the indicator to automatically show the true temperature, without having to
manually apply a correction.

When the Custom or User Calibration is active the indicator will show the REM beacon lit
continuously. The use of User calibration can make a significant difference to the accuracy of
the instrument, and this REM beacon provides a clear and continuous indication of the
calibration status. This is pre configured at Isotech and will only need adjustment when the
instrument is re-calibrated.

To alter the calibration status press the Scroll key until the upper display shows,

CAL
The lower display will indicate either,
USEr for user calibration

Or
FACt for factory calibration of the indicator, i.e. User Cal OFF

Use the UP and DOWN keys to toggle between the two values.

When calibrating an unknown sensor against a calibrated probe it may be necessary to switch
the calibration off for the unknown, and on for the calibrated probe.

Instrument Address (Comms Models only)

Like the controller, the indicator has a configurable "address" which is used for PC
communications. Each instrument has an address; this allows several instruments to be
connected in parallel on the same communications bus. The default value is 2 (The controller
defaults to 1). This address would only need to be changed if more than one Dry Block is
connected to the same PC port.

To check the Address value press the scroll key until the top display indicates,

Addr

The lower display will show the current value that can be modified with the UP and DOWN keys.

HYPERION R

HANDBOOK

ISSUE 05 04/01

Monitoring the Indicator Status

For the indicator the REM beacon is lit continuously when the user calibration is active, the REM
beacon flashes when the PC communications port is active.

Units

Momentary pressing the Scroll key will show the controller units C or F.

Advanced Indicator Operation

The indicator can be configured with up to five custom calibration points; the points contain
"data pairs". First the temperature (point) and secondly the Error (offset) at this temperature
point. Isotech Dry Block calibration certificates will show the values to suit a particular sensor.

These values can be inspected, and modified with the following procedure,

Press the PAGE key until the display indicates,

ACCS
LiSt

Press the SCROLL key until the display shows,

CALIBRATION DATA EXAMPLE

A maximum of five points may be entered, shown as Pnt 1 to Pnt 5 for the temperature point
and Ofs 1 to Ofs 5 for the offset values.

The Pnt values must be entered in ascending order.

Set a Pnt to a value lower than the previous point to disable it.

The indicator would be programmed with the following data:

Pnt 1 100 Ofs 1 0.8
Pnt 2 300 Ofs 2 1.1
Pnt 3 500 Ofs 3 2.1
Pnt 4 -999 Ofs 4 0
Pnt 5 -999 Ofs 5 0

Using the PC Interface (Optional)

An RS422 PC interface and a special converter cable that allows use with the a standard
RS232 port. When using the bath with an RS232 port it is essential that this converter cable is
used. Replacement cables are available from Isotech, part number ISO-232-432. A further
lead is available as an option, Part Number ISO-422-422 lead which permits up to 5 instruments
to be daisy chained together.

The benefit of this approach is that a number of calibration baths may be connected together
in a "daisy chain" configuration - and then linked to a single RS232, see diagram.

Note: The RS 422 standard specifies a maximum lead length of 1200M (4000ft). A true RS422
port will be required to realise such lead lengths. The Isotech conversion leads are suitable for
maximum combined lead lengths of 10M that is adequate for most applications.

Connections

For RS232 use simply connect the Isotech cable, a 9 to 25 pin converter is included to suit PCs
with a 25 pin serial converter.

INITIAL TESTING

This unit was tested before despatch to you but please check its operation as outlined below.

After connecting the Hyperion to the electricity supply, the temperature controller display will
show the temperature of the block and the last set-point value.

Change the set-point to 50°C and observe that the block temperature rises and settles to this

value.

Change the set-point to 0°C, this should cause the cooling to operate and bring the
temperature to 0°C.

A probe connected to the indicator and placed into the cavity pocket should indicate the true
cavity temperature.

Repeat the above to the limit of the units temperature range to ensure it works correctly.

Your unit should have performed as described above and can now be used for calibration.

If any problems or faults arise during these tests please contact us or our agents for help and
advice.

MAINTENANCE

The only moving parts are the fans. They have sealed-for-life bearings. Depending on the
environment in which it is used, periodic cleaning of them and the inside of the case is
recommended. Cleaning may be accomplished by the use of a small dry paint brush.

The instrument should be periodically checked to ensure it is in good order both mechanically
and electrically.

THE BASIC WORKINGS OF THE HYPERION R

The purpose of the Hyperion models is to provide an adjustable isothermal enclosure for
calibration purposes.

The isothermal enclosure consists of an aluminium block.

The block is heated and cooled by two Peltier modules which are controlled, via a sensor in the
block, to a temperature controller.

There are electrically driven fans in the unit which run continuously and cool the heatsinks and
the electronics.

Please note:-

The minimum temperature obtainable in the block is governed by the ambient air temperature.
The unit is capable of producing a block temperature of 30°C below the ambient air

temperature.
