JQE SPECIAL OPR 092611
4-3
4.3.4
ZERO CURRENT MONITOR CALIBRATION
1.
At the rear panel, connect DVM between pin 1 and pin 6 (DVM return) of the MONITOR
PORT connector.
2.
Adjust C.MON ZERO potentiometer (accessible through top cover) until DVM reads 0V
(tolerance: 0 to +1mV).
4.3.5
LOCAL FULL SCALE (FS) OUTPUT VOLTAGE CALIBRATION
NOTE: In effect only for local operation.
1.
Set front panel VOLTAGE control to the full clockwise position.
2.
At the rear panel connect DVM between terminals 2 and 4 of TB501 with the DVM refer-
ence terminal connected to terminal 4.
3.
Adjust E
OUT
FS potentiometer (accessible through top cover) until output voltage reads
25V (tolerance: ±5mV).
4.3.6
REMOTE FULL SCALE (FS) OUTPUT VOLTAGE CALIBRATION
NOTE: In effect only for remote operation.
1.
Turn the JQE special power supply off.
2.
Remove the link between terminals 5 and 6 of TB501 at the rear panel.
3.
Connect the External Programming resistor required for FS calibration (see PAR. 4.2)
between terminals 4 and 6 of TB501 at the rear panel.
4.
Turn the unit on and adjust E
OUT
FS potentiometer (accessible through top cover) until out-
put voltage reads 25V (tolerance: ±5mV).
4.3.7
FULL SCALE (FS) VOLTAGE MONITOR CALIBRATION
This calibration procedure should follow either PAR 4.3.5 for local voltage control or PAR. 4.3.6
for remote control.
1.
At the rear panel. connect DVM between pin 2 and pin 7 (DVM return) of the MONITOR
PORT connector.
2.
Adjust V.MON FS potentiometer (accessible through top cover) until DVM reads +10V (tol-
erance: ±2mV).
