11.4.1.3 I Range High DC, Low Current coefficient
The power source will now be in DC mode. Change the programmable load to DC mode..
Make sure the load in connected (switch is closed) and adjust the DC voltage and load
setting for a current of 1.0 Adc ± 10%. When using a programmable load, set the load to CC
mode and program 0.01A. When using a resistive load, set the load for 50V/ 1A = 50 Ohms.
Highlight the Measured I field value, then enter the current reading from the DMM (select
rear input terminals for current shunt DC 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 10 mVdc measurement equals 1.0Adc. For a CS-20 model 0.05 Ohm shunt, a 50
mVdc measurement equals 1.0Adc.
When done, press the Continue soft key to proceed to the next calibration coefficient.
