Condec UPC5110 - Manual (Page 8)

Operation 5
2.2 Shop Air Operation
1. Turn the SUPPLY SELECT valve (7) to the SHOP AIR position and connect a shop air hose to the male
fill port (4). Maximum input pressure is 150 PSI.
2.3 Initial Setup Procedure
To prepare for actual calibration usage, see Figure 2-2 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).
2. Plug in the power cord (7) and energize the unit by flipping the power switch (18) to OPERATE . The
UPC5100/UPC5110 will perform an internal functional self-check. If acceptable, a 100.00 flashes briefly
and the display returns to a normal reading. Allow at least ten minutes warm-up time. Select the desired
full scale pressure range via the five-position
RANGE SELECT rotary switch (19). For the best accuracy,
the selected range must be greater, but close as possible to, the full scale range of the device under test.
NOTE: Do not switch pressure ranges during a calibration cycle.
3. Set the DISPLAY SELECT switch (16) to the PRESSURE position.
4. Connect the male end of the test hose to the TEST PORT (17) fitting.
5. Connect the swivel fitting end (7/16-20) of the test (output) hose to the device-under-test (use adapters if
required). Tighten all connections properly.
Figure 2-2. Initial Setup Procedure
NOTE: UPC5100 shown, AC input (7) and fill port (4) are on back side of UPC5110 Rack Mountable Calibrator.
6. Optional - if the current (4.0000 to 20.000 mA) measurement features are used, connect the provided
transducer test cable (PN 55092), to the transducer test jacks (14).
When connected, the transducer test cable provides +32 VDC excitation on non-battery units, or +18 VDC
excitation on battery units. The internal impedance (load) is 10 ohms.
NOTE: The +excitation voltage is only available 110-120 VAC operation.
