DESIGNATION
CONTROL PURPOSE
A1R28 I
O ZERO
(NOTE 1) Used to adjust output current of power supply to initial value.
CONDITIONS: current mode, shunt at the output.
A1R20 E
O ZERO
(NOTE 1) Used to adjust output voltage of power supply to zero.
CONDITIONS: voltage mode, no load.
A1R15 I
CURRENT SENSING ZERO
(NOTE 1) Used to adjust current monitor amplifier to zero.
CONDITIONS: voltage mode, no load.
A1R16 I
FULL SCALE CURRENT ADJUST
(NOTE 1)
Used to calibrate the full scale value of the output current.
CONDITIONS: current mode, shunt at the output.
A1R11 V
REF
(NOTE 1) Used to calibrate full scale voltage.
CONDITIONS: voltage mode, no load.
A1R12 I
REF
(NOTE 1) Used to adjust internal full scale current.
CONDITIONS: current mode, shunt at the output.
A8S1 “G” Option Selector (NOTE 2) “G” Option Selector (NOTE 2)“G” option units only: Enables/Disables “G”
Option circuits so unit can function as “slave” unit under control of
another “G” option unit functioning as a “master.” Factory default position
is ON: unit functions as a “master.”
A8R7 Display Contrast Adjust Adjusts contrast of front panel alphanumeric display.
A3S1 Node Address (NOTE 3) Used to select Node address (node number or channel number) of the
MBT Power Supply from 1 - 31
A1TP1 Test Points Provides four test points used for testing/calibration
1 -CURRENT REFERENCE
2 -CURRENT MONITOR
3 - VOLTAGE REFERENCE
4 - COMMON
NOTES:
1. These adjustments must be done in accordance with the calibration procedure (see PAR. 5.5 or refer to procedure avail-
able at MBT front panel by entering MENU and selecting CALIBRATION (see PAR. 3.2.2.4).
2. This switch is not included on some older models; refer to Kepco applications engineering for assistance in disabling the
“G” option.
3. The NODE ADDRESS selector is not accessible through top cover on some older models; it is necessary to remove the
top cover to set the node address.
