6.13.5.4. Adding a Recorder Offset to an Analog Output
Some analog signal recorders require that the zero signal is 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 M200EH/EM by defining a zero offset, a small voltage (e.g., 10% of span).
To add a zero offset to a specific analog output channel, press:
