security_code
When autocal is secured, you must enter the correct security code to perform an
autocal (when shipped from the factory, autocal is secured with the security code
3458). When autocal is not secured, no security code is required. Refer to the
SECURE command for more information on the security code and how to secure
or unsecure autocal.
Remarks
– Since the DCV autocal applies to all measurement functions, you should
perform it before performing the AC or OHMS autocal. When ACAL ALL is
specified, the DCV autocal is performed prior to the other autocals.
– The AC autocal performs specific enhancements for ACV or ACDCV (all
measurement methods), ACI or ACDCI, DSAC, DSDC, SSAC, SSDC, FREQ, and
PER measurements.
