Current Measurement Calibration
This menu is for calibration of the power source’s current measurement functions. The
power source uses up to four measurement ranges depending on model. Each range has
two calibration coefficients. Follow the on-screen prompts to complete the complete
calibration sequence for all ranges and coefficients.
Move the cursor to the “Enter Password” field and enter the number “9527” as the
password. Press the [Enter] key to confirm.
Press the
Current Measurement
soft key to display the calibration screen.
11.4.1.1 I Range High AC, Low Current coefficient
Make sure the load in connected (switch is closed) and adjust the AC voltage and load
setting for a current of 1.0 Aac ± 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 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 10 mVac measurement equals 1.0Aac. For a CS-20 model 0.05 Ohm shunt, a 50
mVac measurement equals 1.0Aac.
When done, press the
Continue
soft key to proceed to the next calibration coefficient.
