5.9.3.9. 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 GFC7001T/GFC7001TM by defining
a zero offset, a small voltage (e.g., 10% of span).
To add a zero offset to a specific analog output channel, select the ANALOG I/O
CONFIGURATION submenu (see Figure 5-3) then press:
