COMMISSIONING

3.1.

Assembly

When a three core mains lead with bare ends is provided it should be connected as
follows:
Any interruption of the mains earth conductor inside or outside the instrument will make the
instrument dangerous. Intentional interruption is prohibited. The protective action must not
be negated by the use of an extension cord without a protective conductor.

Power supply

3.2.1. Main power supply

Check that the instrument operating voltage marked on the rear panel is suitable for the
local supply.
!
Warning !
Should it be necessary to change the operating voltage, proceed as follows:
1) Disconnect the instrument from all voltage sources.
2) Remove the screws which retain the top cover and lift off the cover.
3) Change the transformer connections as follows:
for 230V operation connect the live (brown) wire to pin 15
for 115V operation connect the live (brown) wire to pin 14
for 100V operation connect the live (brown) wire to pin 13
4) Refit the cover and the secure with the same screws.
5) To comply with safety standard requirements the operating voltage marked on the rear
panel must be changed to clearly show the new voltage setting.
6) Change the fuse to one of the correct rating, see below.
3.3.

Calibration

All parameters can be calibrated without opening the case, i.e. the generator offers
« closed-box » calibration. All adjustments are made digitally with calibration constants
stored in EEPROM. The calibration routine requires only a DVM and a frequency counter
and takes no more than a few minutes.
