Getting Started

Voltage Test

1. Set the voltage of the selected output to 10 V by pressing:

VSET 1 0 ENTER

2. Check that the display reads approximately 10 V and 0 A and the CV annunciator is on indicating that the supply is in

the constant voltage mode of operation.

Overvoltage Test

1. Program the overvoltage protection (OVP) to 19 V by pressing:

OV 1 9 ENTER

SET

2. Set the voltage to 16 V by pressing:

VSET 1 6 ENTER

3. Check that the display reads approximately 16 V and 0 A.

4. Set the voltage to 20 V by pressing:

VSET 2 0 ENTER

5. Check that the display reads "OVERVOLTAGE’’

6. Reset the supply by pressing:

VSET 1 6 ENTER RESET

7. Check that the display reads approximately 16 V and 0 A.

Current Test

1. Turn off the supply.

2. Remove the barrier block cover from the output to be tested and connect a short circuit (jumper wire) between the + V

and -V terminals of the output being tested.

3. Turn on the supply.

4. Use the

to select the output being tested.

5. Set the voltage to a volts by pressing:
