Section 3: Adjustment 

DMM6500 6½-Digit Multimeter with Scanning Calibration and Adjustment Manual 

 

3-22 

DMM6500-905-01 Rev. E June 2021 

 

Command parameters for a dc current adjustment 

When calibrating your DMM6500 for a dc 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 along with the calibrator stimulus value. 

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_DCI_10uA_fs_pos") 

cal.adjust.step.execute("cal_DCI_10uA_fs_pos", <

calibrator stimulus value

>) 

You must send the 

cal_TS6

 first.
