Input Zero

Determines and corrects for the input zero and stores the result in volatile memory. An
Input Zero is stored only for the input channel selected. Each input has its own set of
Input Zero stores, for all of the applicable range/function combinations. For OHMS
function an independent Input Zero should be executed for the two/four wire connection
and for the low/normal current selection. The PRT function utilizes input zero's obtained
in the relevant OHMS/TRU_OHMS ranges.
ZERO?
Causes an Input Zero operation to be executed for the selected range and function, if the
instrument is not in a calibration mode.
MZERO?
Multiple ranges are zeroed for the selected function, starting at the highest range. If an
error is detected further zeroing ceases.
Responses
The value returned (Nr1) identifies pass (0) or failure (1)of input zero. The error can be
found in the device dependent error queue.
Execution Errors
Execution errors are generated if calibration is enabled, PRT function is selected or a
scan operation is selected.

Wait

This command conforms to the IEEE 488.2 standard requirements.
WAI
Prevents the instrument from executing any further commands or queries until the No
Pending Operations Flag is set true. This is a mandatory command for IEEE-488.2 but
has no relevance to this instrument as there are no parallel processes requiring Pending
Operation Flags.
