the DVM reads as close as possible to (but not less than) the rated model voltage (e.g., 75V
for KLP 75-33).
3. Tap the DC OUTPUT switch to accept the value; the status display now reads
OUTV
. At the
ANALOG I/O PORT J2, connect the DVM (M– to pin 13, M+ to pin 6) and the d-c power
source (V– to pin 9, V+ to pin 3); set the d-c source output to 10.00V. Rotate the
VOLTAGE
control to increase or decrease the output voltage until the DVM reads as close as possible
to 10V.
4. Tap the DC OUTPUT switch to accept the value. The status display reads
C ?
. Tap the DC
OUTPUT switch to proceed to Current Calibration (see PAR. 4.3.2), or tap either VOLTAGE
or CURRENT control to advance to next choice
4.3.2 CURRENT CALIBRATION (LOCAL)
During current calibration, the current, current readback and analog current readback are cali-
brated.
1. The status display reads
LOAD
. When the shunt and DVM are connected per PAR. 4.3, step
4, tap the DC OUTPUT switch. The status display reads
CMAX
.
2. Rotate the CURRENT control to increase or decrease the DVM reading until the DVM read-
ing corresponds as close as possible to maximum rated current (Calculate current as fol-
lows:
I (Amperes) = DVM reading (Volts) / Shunt Resistance (Ohms).
3. Tap the DC OUTPUT switch to accept the value. The status display reads
C_0
. Rotate the
CURRENT control to increase or decrease the DVM reading until the DVM reading corre-
sponds to minimum positive or zero current (Calculate current as follows:
I (Amperes) = DVM reading (Volts) / Shunt Resistance (Ohms).
4. Tap the DC OUTPUT switch to accept the value. The status display reads
CMAX
. Rotate the
CURRENT control to increase or decrease the DVM reading until the DVM reading corre-
sponds as close as possible to (but not less than) the maximum rated current (see Table 1-2)
Calculate current as follows:
I (Amperes) = DVM reading (Volts) / Shunt Resistance (Ohms).
5. Tap the DC OUTPUT switch to accept the value; the status display now reads
OUTC
. At the
ANALOG I/O PORT J2, connect the DVM (M– to pin 13, M+ to pin 7) and the d-c power
source (V– to pin 9, V+ to pin 1); set the d-c source output to 10.00V. Rotate the
CURRENT
control to increase or decrease the output voltage until the DVM reads as close as possible
to 10V.
6. Tap the DC OUTPUT switch to accept the value. The status display reads
EXT?
. Tap the DC
OUTPUT switch to proceed to External Calibration (see PAR. 4.3.2), or tap either VOLTAGE
or CURRENT control to advance to next choice
4.3.3 EXTERNAL CALIBRATION (LOCAL)
During external calibration the external analog reference voltages used to establish full scale
output current and voltage are calibrated and defined. The factory default calibration is 10V pro-
grams full scale output, however the following procedure allows any d-c value up to 10V to pro-
gram full scale, while a voltage proportionately less programs a corresponding decrease in the
output.
