Cable Connection for Low-voltage Range Calibration

 

 

 

The dialog boxes below ask for a measurement and entry of the DC and 
AC reading from the meter. These measurements will be used for the 
Output Channel calibration so that the low voltage Input Channel 
calibration is provided with an accurately calibrated signal source.
