ZERO_n
Signal Zeroing Enable
Syntax:
ZERO_n <state>
where n is either A or B
Parameters:
The parameter <state> is a <number> which can be 0 or 1. If the number is 0,
then readings are not adjusted by the stored zero reference. If the number is
1, then readings are adjusted by the stored zero reference.
Function:
This command enables or disables the zeroing feature. Zeroing causes the
stored zero reference (see STOZERO_n command) to be subtracted from
incoming signal readings before the incoming signal is used in measurement
calculations.

Signal Zeroing Enable Query
Syntax:
ZERO_n?
where n is either A or B
Parameters:
None
Function:
This query returns a value showing whether or not zeroing is enabled or
disabled.
Returns:
<state>
<state> is of type <number> and represents the integer 0, if zeroing is enabled,
or 1, if zeroing is disabled.

ZEROVAL_n?
Zero Signal Query
Syntax:
ZEROVAL_n?
where n is either A or B
Parameters: None
Function:
This query returns the current value being used for zeroing.
Returns:
<zeroval>
<zeroval> is of type <number> in exponential notation. The units of this value
are the numerator of the detector’s responsivity, i.e. amps for Low Power
detectors and volts for High Power and Energy detectors.
