Mains Operating Voltage
Check that the instrument operating voltage marked on the rear panel is suitable for the local
supply. Should it be necessary to change the operating voltage, proceed as follows:
1) Disconnect the instrument from all voltage sources.
2) Remove the 4 screws from the underside and lift off the case upper.
3) Remove the 3 screws securing the pcb to the case lower and lift out the pcb with front and rear
panels attached.
4) Change the voltage settings by changing the soldered links as shown below:
5) Reassemble in the reverse order.
6) To comply with safety standard requirements the operating voltage marked on the rear panel
must be changed to clearly show the new voltage setting.
Note: The transformer primary is protected by an integral thermal fuse which remains unchanged
when the operating voltage is altered.
Mains Lead
When a three core mains lead with bare ends is provided it should be connected as follows:-
WARNING! THIS INSTRUMENT MUST BE EARTHED WHEN OPERATED FROM AN AC LINE SUPPLY
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.
Handle
Adjust the handle position by pulling out the ends and rotating the handle to the desired position.
There are sixteen possible positions including five facing forward which provide upward tilts for
the most convenient bench operation. The handle may be swung out of the way to the back or
front of the instrument if no tilt is required. The natural spring in the handle will lock it into position
when the handle is released.
