The relationship with the reference channel
Even if the input type or the measurement range of the difference computation channel
and the reference channel is not the same, the difference computation is performed
according to the following rules.
• When the decimal position between the reference channel and the difference
computation channel is different, the measured value of the reference channel is
adjusted to the decimal position of the measured value of the difference computation
channel to make the computation.
Example : When the measured value of the difference computation channel is 10.00
and the measured value of the reference channel is 100.0, the
computation result becomes 10.00 – 100.0 = –90.00.
• When the units for the reference channel and the difference computation channel are
different, the measured value is not adjusted.
Example : When the measured value of the difference computation channel is 10.00 V
and the measured value of the reference channel is 5.00 mV, the
computation result becomes 10.00 V – 5.00 mV = 5.00 V.
• When the reference channel is set to [Scale] or [Sqrt], the computation uses the
scaled values.
