7.5 Leak Test
Table 2 on page 15 gives the maximum leak rates for each type of PV 62XG / PV 62X - IS
pressure station.
7.5.1 Preparation
To do a leak test, we recommend these items:
1. A DPI
620G / DPI 620G - IS calibrator.
2. The applicable PM 620 / PM 620 - IS module for the pressure station:
• PV 621G / PV 621 - IS models: P/N PM620 - 13G / PM620S - 13G (20 bar)
• PV 622G / PV 622 - IS models: P/N PM620 - 165G / PM620S - 165G (100 bar)
• PV 623G / PV 623 - IS models: P/N PM620 - 23A / PM620S - 23A (1000 bar)
3. An applicable blanking adaptor to seal the test port connection.
4. PV
623G / PV 623 - IS models only: Demineralized water.
7.5.2 Procedure
1. Seal the test port connection with the blanking plug.
2. Connect the applicable PM
620 / PM 620 - IS module:
• PV 621G / PV 621 - IS models: P/N PM620 - 13G / PM620S - 13G (20 bar)
• PV 622G / PV 622 - IS models: P/N PM620 - 165G / PM620S - 165G (100 bar)
• PV 623G / PV 623 - IS models: P/N PM620 - 23A / PM620 - 23A (1000 bar)
3. Connect a DPI 620G / DPI 620G - IS calibrator and set the power on.
4. Do the test for maximum pressure or maximum vacuum.
7.5.2.1 Maximum Pressure Test
1. Use the applicable procedure for the pressure station to set the maximum pressure:
• PV 621G / PV 621 - IS models: Chapter 3 Set the pressure to 20 bar.
• PV 622G / PV 622 - IS models: Chapter 4 Set the pressure to 100 bar.
• PV 623G / PV 623 - IS models: Chapter 5 Set the pressure to 1000 bar.
2. Set the DPI 620G / DPI 620G - IS calibrator to do a Leak Test:
• Channel Settings: Units = Bar; Utility = Leak Test
• Settings: Test Time = 00:01:00 (1 minute)
3. Let the pressure become stable for 1 minute.
CAUTION
To prevent damage to the pressure station, do not let dirt get into
the pressure mechanism. Before you connect equipment, make sure it is clean.
CAUTION
Ice in the pressure mechanism can cause damage. If the
temperature is less than 4°C (39°F), drain all water from the pressure station.
