The Process span
is the anticipated lowest and highest weight (Min and Max Weight) for the
gauge to measure. Calibrate the W-4510 within these settings. These define the endpoints
for the calibration and the linearizer curve. This does not define the span for the output
current loop (see current loop span, page 104).
Ohmart enters these parameters at their factory based on information received at the time of
the order. If the values are correct, no change is necessary.
Note: The Min and Max weight values for the process span are essential to proper calibration
of the system. You must enter the Min and Max density values before you can perform an
initial calibration. If you change the values for the process span Min or Max densities, you
must perform a new initial calibration procedure.
You must modify the span setting if you move the W-4510 from its intended location or are
measuring on a different span. In any case, it is a good practice to verify that the setting is
correct before performing an initial calibration.
