3. Allow the instruments and cables to settle for five minutes.
4. On the calibrator, enable the
OPR
key and the
EX SNS
key.
5. Make sure that the OPERATE display and EX SNS keys are illuminated.
Command parameters for a resistance adjustment
When calibrating your DMM6500 for a resistance 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_4W_10ohm_fs")
cal.adjust.step.execute("cal_4W_10ohm_fs", <
calibrator stimulus value
>)
Since the temperature sensor is adjusted here, you are advised to perform all resistance
adjustment steps in the same calibration session. If only a partial calibration is performed
and the original T_cal differs from the new T_cal, the ranges that are not adjusted may less
accurate. Completing an adjustment for all of the resistance steps will remove these errors.
You must send the
cal_TS7
first.
