11.4.1.2 I Range High AC, High Current coefficient
The next calibration point is for high AC current measurements. Adjust the programmable
load to 24.0 Aac. Adjust the AC voltage on the source to 150Vac to support this current
draw. When using a R Load, adjust the resistor value to 150V/24A = 6.25 Ohm or as close to
it as possible and then adjust the voltage as needed to obtain 24Aac ± 10 %.
Note:
Depending on the CPS100 model and max. current rating, the actual high current
value may be different that shown in this example. Always follow the on-screen
prompted current setting values.
Highlight the
Measured I
field value, then enter the current reading from the DMM (select
rear input terminals for current shunt AC voltage measurement). Based on the shunt value,
calculate the current from the voltage and enter this value. E.g. for a CS-50 model 0.01 Ohm
shunt, a 240 mVac measurement equals 24.0Aac.
When done, press the

soft key to proceed to the next calibration coefficient.
