2.0 Operation
2.1 Pressure Cylinder (PN 59533) Filling Procedure
NOTE: Condec strongly recommends that the external nitrogen supply cylinder be pressure-tested and re-certified
every five years from date cylinder was manufactured per U.S. DOT. 3AL Regulation, Title 49 CFR, parts 173 and 178.
To initially fill or refill the external pressure cylinder (2,216 PSI max.), proceed as described below.
1. Close the CYLINDER valve by rotating clockwise until it stops.
2. Connect the customer supplied fill hose, to a clean regulated nitrogen source, with an output pressure
gauge and vent valve.
3. Connect the other end of the customer supplied fill hose to the female CGA-580 brass CYLINDER valve
fitting.
4. Open the CYLINDER valve by rotating counter-clockwise until it stops.
5. Slowly open the valve on the nitrogen source and allow the gas to flow into the pressure cylinder. The
customer supplied output pressure gauge indicates the amount of pressure within the internal cylinder.
NOTE: Cylinder is equipped with a rupture disk.
6. Use the following procedure to fill the cylinder:
a) Fill cylinder to 1,000 PSI at a rate of charge equal to a minimum of two minutes, then wait five
minutes for system to stabilize.
b) Fill cylinder from 1,000 PSI to 2,216 PSI at a rate of charge equal to a minimum of two minutes.
c) Wait five minutes for cylinder to stabilize before using.
7. Close the CYLINDER valve by rotating clockwise until it stops.Vent nitrogen source and remove fill hose.
2.2 Initial Setup Procedure
To prepare for actual calibration usage, see Figure 2-1 below and proceed as follows:
1. Check that the COARSE ADJUSTMENT valve (2) is closed (rotate clockwise until it stops) and that the
Vent valve (8) is open (two turns counter-clockwise from its stop). Verify that the REGULATOR (1) is
closed (rotate counter-clockwise until it stops).
2. Plug in the power cord (7) and energize the unit by depressing the POWER switch (18). The
UPC5200/UPC5210 performs an internal functional self-check. Allow at least 10 minutes warm-up time.
3. Select the desired full scale pressure range via the three-position rotary switch (19). For the best
accuracy, the selected range must be greater than, but close as possible to, the full scale range of the
device-under-test.
NOTE: Do not switch pressure ranges during a calibration cycle.
4. Set the DISPLAY SELECT switch (16) to the PRESSURE position.
5. Connect the male end of the test hose to the TEST PORT (17) fitting.
6. Connect the swivel fitting end (7/16-20) of the test (output) hose to the device-under-test using adapters
if required. Tighten all connections properly.
7. UPC5200: Connect the male end of the input hose (3) to the female CGA-580 brass CYLINDER (5) valve
fitting.
UPC5210: Connect the male end of the input hose (3) to the female CGA-580, customer supplied,
pressure source.
8. Connect the swivel fitting end (7/16-20) of the input hose (3) to the INPUT PORT (4) fitting. Tighten all
connections properly.
