5.9.3.9. ADDING A RECORDER OFFSET TO AN ANALOG OUTPUT
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 in the T200 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 5-5) then press:
