Set range
Before starting calibration work, use the SFC to check that the set range of the trans-
mitter agrees with the specifications. If they do not correspond, use the SFC to set the
correct range. Procedures are found in "6-7-8 : Display or Change Low/High Limits
and Span of Set Range".
The set range is calibrated assuming that the low limit 20 kPa and the high limit is 100
kPa.
