Adding a Recorder Offset to the TEST Channel 4.9.1.5.
Some analog signal recorders require that the zero signal 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 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:
