Condec UVC1010 - Manual (Page 5)

Operation 3
2.0 Operation
2.1 Input Air Pressure Supply
See Figure 2-1 below and proceed as described below.
NOTE: The air pressure source used must have a vent valve and be regulated to provide a maximum output of 160
PSIG.
1. Pull PRESSURE LIMIT CONTROL (1) knob outward and rotate counter-clockwise until it stops.
2. Connect the input hose, supplied by customer, to a clean regulated shop air source.
3. Connect the other end of the input hose, supplied by customer, to the male input port fitting located on
rear of unit. Use a customer supplied AN-4 37° adapter fitting, and cheat seal pad (recommended)
between input hose & input port.
Figure 2-1. Input Operation Procedure
NOTE: UVC1000 shown, UVC1010 Rack Mount unit also has an input port on back of unit.
2.2 Pressure Measurement Sequence
To prepare for actual calibration usage, see Figure 2-1 above and proceed as follows:
1. Check that the PRESSURE LIMIT CONTROL valve (1) is closed (pull knob outward and rotate clockwise
until it stops). Turn MODE SELECT knob to the required mode of operation.
2. Connect the male quick disconnect end of the port hose, supplied by customer, to one of the ports,
Pressure Port (5) or Vacuum Port (6). Use supplied 1/4 female NPT quick disconnect fitting, (PN 60195)
between port hose and Pressure Port or Vacuum Port.
3. Connect the other end of the port hose, supplied by customer, to the unit under test, using adapters if
required. Tighten all connections properly.
4. Set the customer regulated input pressure to a maximum of 160 PSI.
5. Pressure Mode: Using the PRESSURE LIMIT CONTROL regulator (1), adjust the maximum system input
pressure, as read by the PRESSURE LIMIT MONITOR (3), to any desired value (100 PSI max.) within
scale range of the device under test. Using this technique, the device under test is fully protected from
being accidentally over-pressurized.
Vacuum Mode: Using the PRESSURE LIMIT CONTROL regulator (1), adjust the maximum system input
pressure, as read by the VACUUM MONITOR (4), to any desired value within scale range of the device
under test (-29 in Hg max).
