The calibration procedure
The following calibration procedure applies to HDM3000 DMM. Perform the calibration
procedure in the order listed in this document.
1.
SelfTest and reset-to-zero calibration
2.
DC voltage gain calibration
3.
DC current gain calibration
4.
Ohmic gain calibration
5.
AC voltage gain and flatness calibration
6.
AC current gain and flatness calibration
7.
Frequency accuracy calibration
8.
Capacitance offset calibration (optional)
9.
Complete calibration
SelfTest and reset-to-zero calibration
Each time you perform a reset-to-zero calibration, the instrument stores a new set of offset
correction constants for each measurement function and range. The instrument
automatically sorts all required functions and ranges and stores the new reset-to-zero
