•
The auxiliary error register indicates hardware related errors. If one or more bits
are set, the multimeter needs calibration or repair.
•
The AUXERR? command returns a 0 if no error bits are set.
•
If any bit in the auxiliary error register is set, the multimeter sets bit 0 (hardware
error) in the error register. Reading the auxiliary error register does not clear bit
0 in the error register. You must read the error register (ERR? command) to
clear it.
•
Bits in the auxiliary error register cannot be masked to prevent them from setting
bit 0 in the error register.

As an example, assume the AUXERR? command returns the weighted sum 3072.
This means that the errors with weighted values of 1024 (ROM checksum,
low-order byte) and 2048 (ROM checksum, high-order byte) have occurred.
Autozero. Enables or disables the autozero function. The autozero function
applies only to DC voltage, DC current, and resistance measurements.
