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
