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:-
1) When the source is switched on, the fluorescent indicator panel displays
the measured value (upper display) and the set point value (lower
display).
2) 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.
NOTE
All other control parameters are factory set and locked. For correct
operation, it should not be necessary to adjust any other parameters.
