c. With calibration pressure at zero, confirm the gauge indicates zero.

d. Apply calibration pressure at 100% of range. confirm the gauge indicates maximum span.

e. Carry out 5 points calibration check at 0%, 25%, 50%, 75%, 100% of span for rising and falling.

f. Record all results in Instrument Calibration (Indicator, Recorder) Checksheet.
