6.9.4.4. ANALOG OUTPUT OFFSET ADJUSTMENT
Some analog signal recorders require that the zero signal to be significantly different from the baseline of the
recorder in order to record slightly negative readings from noise around the zero point. This can be achieved in
the M100E by defining a zero offset, a small voltage (e.g., 10% of span), which can be added to the signal of
individual output channels by activating the ANALOG I/O CONFIGURATION MENU from the DIAG Menu (refer
to Figure 6-17), then press:
DIAG AIO RECORD OFFSET: 0 MV
