5.9.3.4. 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 6200T 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 5-16), then press:
