Balancing the Measured Current Final Value
Device settings: OUTPUT ON; USET 2.00; ISET = I
nom
Output: Shorted with shunt
– Measure current I
s
at shunt R
s
and balance the measured
Iout value which appears at the right-hand display with
R663a to:
Iout = I
s
 28 mA where I
nom
= 12.5 A
= I
s
 58 mA where I
nom
= 25 A
= I
s
 105 mA where I
nom
= 50 A
= I
s
 220 mA where I
nom
= 75 A
= I
s
 300 mA where I
nom
= 100 A
= I
s
 470 mA where I
nom
= 150 A
Balancing the Voltage Setpoint Zero-Point
Device settings: OUTPUT ON; USET 0.10; ISET 2.00
Output: Idle
– Measure output voltage U
A
with the digital voltmeter and
balance with R554 to:
100 mV  5 mV where U
nom
= 40 V
100 mV  8 mV where U
nom
= 52 V
100 mV  10 mV where U
nom
= 80 V
Balancing the Voltage Setpoint Final Value
Device settings: OUTPUT ON; USET = U
nom
; ISET 2.00
U
A
= 40.00 V  30 mV where U
nom
= 40 V
= 52.00 V ± 43 mV where U
nom
= 52 V
= 80.00 V ± 60 mV where U
nom
= 80 V
Balancing the Measured Voltage Zero-Point
Device settings: OUTPUT ON; USET 0.00; ISET 0.00
Output: Shorted
– Balance measured voltage value Uout, which appears at the
left-hand display, with R 657 to:
– 0.01  Uout  0.01 where U
nom
= 40 V
– 0.02  Uout  0.02 where U
nom
= 80 V or 52
V
Balancing the Measured Voltage Final Value
Device settings: OUTPUT ON; USET = U
nom
; ISET 2.00
Output: Idle
– Connect the digital voltmeter to the output and measure
voltage U
A
.
– Balance measured voltage value Uout, which appears at the
left-hand display, with R 651 to:
Uout = U
A
 20 mV where U
nom
= 40 V
Uout = U
A
 23 mV where U
nom
= 52 V
Uout = U
A
 40 mV where U
nom
= 80 V
