Equipment Setup; Preliminary Operations - Fluke Calibration 4322-SYS-NAVAIR Service Manual

Equipment Setup

The operator can choose to calibrate all installed modules or only selected ranges. A
pressure supply sufficient to reach the selected modules' maximum pressure must be
connected. For example, to calibrate the G10M (1500 psig) module, a gas cylinder with
approximately 2000 psi could be used, or a gas supply with a minimum pressure of
500 psig and the 4322 Intensifier could be used. To calibrate the G70M (10,000 psi)
module, the 4322 intensifier must be used.
The supply must be disconnected in order to calibrate the barometer
module and the A150K module.

Preliminary Operations

Prepare for the calibration procedure as follows:
1. Turn on the 4322 Pressure Controller (the Controller) and let it warm up for at least
1 hour.
2. Turn on the reference pressure standard and let it warm up for at least 1 hour.
3. Connect the Nitrogen Cylinder supply to the Controller as follows (see Figure 3-1):
Do not connect the supply to the Controller when calibrating the barometer
module and the A150K module. For all other modules, make sure the
supply is connected.
a. Make sure the Nitrogen Cylinder pressure is more than 500 psig and no more
than 2000 psig.
To prevent injury or possible death, do not over pressurize the
Nitrogen Cylinder. Maximum pressure of the Cylinder is 2000
psig.
b. Connect the male end of the regulator hose to the Nitrogen Cylinder regulator
port.
c. Connect the female end of the regulator hose to the male SUPPLY QC port on
the Intensifier.
