50 DF-150E Maintenance and Calibration Checks
When performing a Calibration Adjustment (as described above) the Span pot
does not have a Span Calibration Reference value, as a result there is no need
to throw the View Ref toggle switch. Simply adjust the span pot as described
above to make the display equal the Span gas value.
