CALIBRATION PROCEDURE
interaction and simplifies calibration. In Steps 1 to 4 the unit is “nulled” to zero
readout with zero input signal voltage. In Steps 5 and 6, the span adjustments
are made to establish the required slope of the transfer curve. Then in Step 7, the
transfer curve is shifted up or down as required by setting the offset adjustments.
In Step 8, the final “tweaking” adjustments are made at minimum and maximum
signal voltage. Setting the decimal points in Step 9 completes the calibration.
Before calibrating, the READOUT SPAN (Rs), SWING VOLTAGE (Vs), and
SPAN PER VOLT (Rs/Vs) must be determined.
