Command parameters for an ac current adjustment
When calibrating your DMM6500 for an ac current adjustment, use the following command
parameters.
Send each command parameter twice. First, send the parameter using the setup command. Second,
send the parameter using the execute command.
The example code below uses the first line of code from the table below. Send all command
parameters using this command.
cal.adjust.step.setup("cal_ACI_100uA_1kHz_tenth")
cal.adjust.step.execute("cal_ACI_100uA_1kHz_tenth")
