BOP-1K-GL 022814
a. ZERO Calibrations, main channel (voltage or current) (always done first). The only
means of adjustment is the
CAL:DATA
command which provides a total of 4095
increments of adjustment starting at 0, with 2047 increments in either direction to achieve maxi-
mum output levels of ±2.5% of E
Onom
or I
Onom
. Adjust the output to obtain the closest value to
zero.
b. MAX and MIN Calibrations, main channel (voltage or current). The primary means of
adjustment is the
CAL:DATA
command to either increase (
CAL:DATA 1
) or
decrease (
CAL:DATA -1
) the output value. Adjustment can be done in larger increments by
increasing the numeric value, e.g.,
CAL:DATA +10
or
CAL:DATA -10
. Adjust the output to
obtain the closest value above the full scale value.
c. VPR and CPR Calibrations, limit channels (positive and negative voltage or current
protection). The only means of adjustment is the
CAL:DATA
command which pro-
vides a total of 4095 increments of adjustment from zero to maximum. Adjust the output to
obtain the closest value above the full scale value.

those recommended.
