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

= 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
