Commands¶

performZeroCalib¶

Description: Performs a zero correction in the device. It’s recommended to perform this zero correction every time the range changes. The steps taken to perform this comes from the datasheet 6517B-901-01 Rev. B / June 2009 under Zero correct. It is as following. 1- Enable Zero check, 2- Set unit to read, 3- Set range to measure 4- Enable Zero Correction 5- Disable Zero check. For unit and range, it uses the last values selected, either via command or from the configuration file
