Calibration and Adjustment Procedures
This procedure describes calibration and performance verification to the
specifications, As Found data collection procedures, adjustment, and as left
verification procedures for the Product. The procedure is meant to bring the
Product into specification after repair or when the UUT fails the performance
tests.
• Do the As Found data collection with the described setups and pressure set
points. The Product is left in measurement mode and pressure is applied with
the appropriate reference.
• The adjustment procedure can be done in chassis or with a calibration sled,
or COMPASS for Pressure software.
• Do the as left (verification) like the As Found data collection.
Required Equipment
The minimum use specifications in Table 6 are the principal parameters required
for performance of the calibration. Use the minimum specifications to assist in the
selection of alternate equipment, which may be used at the discretion of the
laboratory.
