Calibration with Electronic Regulator
Please refer to the calibration section of the Sprint LC Owner’s Guide.
This appendix describes only the differences when performing calibration
on testers using the electronic regulator.
The calibration functions much the same other than the pressure is now
controlled by the electronic regulator. During a calibration, the electronic
air regulator is also calibrated. If Sprint LC is within calibration tolerance
during an accuracy check, Uson recommends that no adjustment be made.
As in a normal calibration, when performing a pressure calibration, air is
sent OUT of the Sprint LC to supply a calibrated external standard for
comparison to the Sprint LC.
First use the INCREMENT and DECREMENT keypads to ramp up the target
pressure. Target increments are typically in ten or more steps, depending
on the range of the installed sensors.
If necessary, use the PREVIOUS and NEXT keypads (labeled as REG- and
REG+) to adjust the regulated pressure for calibration through the
electronic regulator. The pressure will change slightly with each key press.
It may be necessary to press either the PREVIOUS and NEXT keypad several
times to reach the desired reading.
Match the External Pressure Standard
!
It is important to adjust the electronic regulator
so that the external pressure standard
matches the target value. DO NOT merely
attempt to match the regulated pressure as
shown on the Sprint LC display on the target
value.
