COMMISSIONING
5.1
Inspection on receipt
Physically examine all items for damage that may have occurred during transit. Check the contents against the
packing note.
If any item has been damaged in transit this should be reported to the carrier and to the supplier immediately.
Do not return damaged instruments to the sender as the carrier will not then consider a claim. Save the packing
with the damaged article for inspection by the carrier.
5.2
Connections to mains Supply
Connect the brown lead to live, blue to neutral and green/yellow to earth. When connected to the mains supply
and switched on an indicator will light. At no time should any panels be removed when this mains indicator is
on.
5.3
Heating up/cooling down of the source
The source can be operated at any temperature in the range -10°C/15°F to 80°C/175°F. Set the controller to
the required value as follows:-
(i)
When the source is switched on, the fluorescent indicator panel displays the measured value (upper
display) and the set point value (lower display).
(ii)
To raise or lower the setpoint value, depress the respective up/down button. After a short delay, the
setpoint will change in the required direction. Release the up/down button when the required
temperature value is reached.

All other control parameters are factory set and locked. For correct operation, it should not
be necessary to adjust any other parameters.
