Why has AT Calibration/Verification failed with message options Abort(A) or Retry(T) during manual calibration?
The Calibration software prompts for manual entries of many different DVM readings during the calibration process.
It is important to pay special attention when entering these DVM readings. These entered readings have to be with the correct sign (+ or - ), entries should be in basic units. For Voltage the entry should be in volts (not mV for example) and resistance should be in Ohms (not KOhms for example). Also it is important to set-up the 3458A as directed for each step, the AC+DC manual test is the last test in manual calibration.
If you see the error message "Verification has failed" after calibration, the calibration process has not been able to apply appropriate offsets or previous requested entries may have been incorrect for some reason.
If an entry is significantly different from the expected value the software will request a retry or abort but it is possible to make an entry that is seen by the software as correct but may in fact be wrong due to a wrongly typed value.
It is also important to ensure that the latest firmware is installed (this can be seen on the voltech website www.voltech.com).
