Why does my GE Druck DPI612 have an excessive leak rate (pressure or vacuum)?
- K
  kmartinAug 17, 2025
  An excessive leak rate in your GE Test Equipment could be due to several reasons: * The system might be incorrectly connected (DPI612 to DUT). Ensure that connecting accessories are fitted according to instructions and that the correct sealing method is in use. * The DUT (Device Under Test) may have a leak. Isolate the DUT from the DPI612 and check for leaks in both independently. * There might be a worn pressure seal on the outlet port ('O' ring & backup ring). Inspect the seal on the pressure port for signs of wear and replace if necessary. * The Release Valve might not be fully closed. Make sure the Release Valve is firmly closed.

  Margaret NguyenAug 20, 2025
  If your GE Test Equipment unit is not generating pressure with the integral pump, consider the following: * The mode selector may be incorrectly set. Ensure the mode selector is in the “+” position. * The sensor may not be fitted to the sensor port. Ensure a sensor (or blank IO620-BLANK) is fitted to the sensor port. * The output port may not be connected. Ensure the output port is connected to the DUT or fitted with a suitable blanking plug. * The release valve may not be closed. Ensure the release valve is firmly closed.

  If your GE Test Equipment unit is not generating vacuum with the integral pump, check the following: * The mode selector may be incorrectly set. Ensure the mode selector is in the “-” position. * The sensor may not be fitted to the sensor port. Ensure a sensor (or blank IO620-BLANK) is fitted to the sensor port. * The output port may not be connected. Ensure the output port is connected to the DUT or fitted with a suitable blanking plug. * The release valve may not be closed. Ensure the release valve is firmly closed.

What to do if my GE Druck DPI612 unit will not reach desired pressure?
- D
  Donald BarnettAug 26, 2025
  If your GE Test Equipment unit is not reaching the desired pressure, it could be because the PRV (if fitted) is operating at a lower pressure than required. Check the PRV range (if fitted) and adjust the PRV if the range is suitable. If not, fit the correct range PRV or re-fit the PRV blanking plug supplied with the unit.

What to do if my GE Druck DPI612 unit will not generate pressure with integral priming pump/hydraulic ram?
- J
  Jaime PriceAug 28, 2025
  If your GE Test Equipment unit is not generating pressure with the integral priming pump/hydraulic ram, consider these potential causes: * There may be insufficient hydraulic fluid in the reservoir. Verify the reservoir has sufficient fluid to generate pressure, aiming for at least 75% of its capacity. * The system may not be primed correctly. Follow the priming instructions to ensure air is removed from the system. * The output port may not be connected. Ensure the output port is connected to the DUT or fitted with a suitable blanking plug. * The release valve may not be closed. Ensure the release valve is firmly closed.

What causes excessive leak rate in GE Druck DPI612?
- L
  Lori HernandezAug 31, 2025
  An excessive leak rate in GE Test Equipment can stem from: * The system not being primed correctly. Follow the priming instructions to ensure air is removed from the system. * An incorrectly connected system (DPI612 to DUT). Check that connecting accessories are fitted in accordance with instructions and the correct sealing method is in use. * The DUT (Device Under Test) having a leak. Isolate the DUT from the DPI612 and check for leaks in both independently. * A worn pressure seal on the outlet port (‘O’ ring & backup ring). Inspect the seal on the pressure port for signs of wear and replace as necessary. * The release valve not being closed. Ensure the release valve is firmly closed.

What to do if GE Druck DPI612 unit will not connect to calibration management software?
- S
  Summer AndersonSep 8, 2025
  If your GE Test Equipment unit will not connect to calibration management software, it might be because the communications mode is set to storage. From the DASHBOARD, select SETTINGS, then DEVICES; the USB client port should be set to Communications.
