<NRf> = -9.999999e20 to Specify null offset value
9.999999e20
:OFFSet?
This command lets you establish a null offset (REL) value for channel 1
(CALC3) or channel 2 (CALC4). When Null Offset is enabled, the
result is the algebraic difference between the feed reading (see
FEED <name> above) and the offset value:
CALC3 or CALC4 reading = feed reading - null offset
These commands automatically acquire the null offset values for chan-
nel 1 (CALC3) and channel 2 (CALC4). The next available reading will
become the offset value.
<b> = 1 or ON
0 or OFF
:STATe?
These commands are used to enable or disable the null or offset value
for REL. When enabled, the CALC3 or CALC4 reading will include the
null offset value (see OFFSet
CALC4 reading will not include the null offset.
These query commands are used to read the CALC3 or CALC4 REL
result. When CALC3 or CALC4 is enabled (see
returned value will include the offset value (see
ACQuire).
