5. Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue
until the maximum OVP value is displayed (e.g., 33.00 for 30V model).
6. Press ENTER key to accept programmed OVP value.
7. Press SHIFT/LOCAL key. Verify blue LED goes on. Press A/OCP. Least significant digit
of Current Display and integral red OCP LED at the right of the display blink. Verify
blue
LED goes off.
8. Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue
until the maximum OCP value is displayed (e.g., 26.25 for 25 Ampere model).
9. Press ENTER key to accept programmed OCP value.
10.Press V/OVP key. Least significant digit of Voltage Display blinks.
11. Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue
until the rated output voltage value (e.g., 30.00 for 30V model) is displayed.
12.Press ENTER key to accept programmed voltage value.
13.Press A/OCP key. Least significant digit of Current Display blinks.
14.Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue
until a value of several Amperes of output current is displayed.
15.Connect a digital voltmeter (DVM) to the (+S) and (-S) terminals on the rear panel. Verify that
DVM shows there is no output voltage from the power supply.
16.Press green OUT key. Verify that green LED at left of OUT key goes on.
17.Compare the programmed output voltage value (e.g., 30.00V for 30V model per step 11) with
the voltage reading of the DVM; Verify that the difference between the two does not exceed
±0.1% ± 3C
(*)
.
18.Compare the voltage reading of Voltage Display with that of the DVM; Verify that the differ-
ence between the two does not exceed ±0.2% ± 3C
(*)
.
19.Disable the output by pressing the OUT key; verify front panel Voltage and Current displays
show programmed values of Voltage and Current, respectively and DVM reads 0V.
20.Set power switch to OFF. The unit issues a long beep as it powers down. Disconnect unit
from source power, then disconnect test equipment.
(*) C = 1 count of the last displayed digit.
