For voltage calibration all loads must be disconnected and the sense terminals connected to the
corresponding output terminals. The digital voltmeter will be connected to the output of the
power supply. For current calibration after disconnecting all loads an appropriate shunt resistor
will be connected across output terminals and the digital voltmeter will be connected across the
sense terminals of the shunt resistor.
NOTES: Keys with dual functions are labeled with both a command and a number. The com-
mand label is referred to when the unit is in command entry status; the number is
referred to when the unit is in data entry status.
1. Adjust Crowbar LEVEL control fully clockwise.
2. With the power supply in command entry status , press
CALIB
key. power supply enters
Calibration mode, data entry status .
3. Enter password (4 digits) and press
ENTER
. If password is incorrect,
**WRONG PASS-
WORD**
flashes, then LCD returns to command status. (See PAR. 4.4 to change the pass-
word).
4. If password is correct, LCD reads
VOLTAGE CALIB
. Enter
1
for voltage calibration (see
PAR. 4.3.1), enter
0
to proceed to current calibration.
5. LCD reads
CURRENT CALIB
. Enter
1
for current calibration (see PAR. 4.3.2), enter
0
to exit
Calibration mode.
4.3.1
VOLTAGE CALIBRATION
NOTE: Refer to Figure 2-3 for location of internal power supply controls.
1. With LCD reading
VOLTAGE CALIB. Connect Instr.
, connect DVM to output (+) and (–
) terminals of power supply. then press ENTER.
NOTE: During calibration the
"
(increase) or
ç
(decrease) keys are used for fine adjust-
ments. If necessary, use the
1
(decrease) and
3
(increase) keys for coarse adjust-
ment, then use the
"
or
ç
keys.
2. With LCD reading
Vout ZERO adj.
, monitor DVM and use
"
or
ç
keys to increase or
decrease output voltage as necessary to get DVM reading as close to zero as possible (with-
out going to negative value). If unable to reach zero, adjust E
O
ZERO control as necessary.
Press
ENTER
when complete.
NOTE: If LCD reads
CAN’T ADJUST FULL SCALE
, refer to Section 6 for troubleshooting.
3. LCD will flash
Vout F.S.adj. **WAIT**
then
Vout F.S. adj < >
. Monitor DVM and
use
"
or
ç
keys to increase or decrease output voltage as necessary to get DVM reading
as close as possible to full scale value (without exceeding full scale value). E.g., for ATE 25-
40DMG, adjust for DVM reading as close to 25.000V as possible. Press
ENTER
when com-
plete.
