2.2 OPERATING PROCEDURE
2.2.1 For constant voltage mode adjust controls 3 & 4 clockwise to the maximum position. Switch
on the power ON/OFF switch 7 and adjust controls 5 & 6 to set the desired output voltage. Connect
the load to the output terminals 8 & 10.
2.2.2 For constant current mode adjust controls 5 & 6 clockwise to the maximum position. Adjust
controls 3 & 4 anti-clockwise to the minimum position. Switch on the power ON/OFF switch 7 and
connect the load to the output terminals 8 & 10. Adjust controls 3 & 4 to set the desired output
current.
2.2.3 For restricted current protection mode switch on the power ON/OFF switch 7, adjust controls 3
& 4 anti-clockwise to the minimum position, adjust controls 5 & 6 clockwise to set the desired output
voltage level and then connect the load to the output terminals 8 & 10. Adjust controls 3 & 4
clockwise to set the output current at the desired level for restricted current protection.
! 3. ATTENTION:
3.1 In the event of a short circuit at the output the current will limit at the value set by the current
controls, however the unit should be turned off and the short circuit removed before continuing use.

3.2 The mains power must be switched off before servicing and servicing should be referred to a
qualified person.
3.3 The unit should be stored in a dry and well ventilated place and the power cord removed if
storing for long periods.
