Auto-Zero Operation
Auto-zero function eliminates the offset error in the measurement system of this instrument.
If Auto-zero is set to ON, the internal offset is measured and the offset error is eliminated because the offset
is subtracted from the input measurement value. However, the measurement time is doubled.
Set Auto-zero in ‘A.ZERO’ in
in
.
Auto-zero is performed at the current measurement range in the measurement function and range shown in
the following table.
Auto zero can be performed only once according to the measurement condition or measurement timing.
If ONCE is set and Auto-zero is performed, the offset error is eliminated and then Auto-zero is turned off.
