  Timothy BrowningAug 15, 2025
  If the sample pump in your E Instruments Measuring Instruments sounds slow, stops, or doesn't start, several issues could be the cause. First, ensure the water filter is clean and not soaked, and check the hose connected to the probe for any crushing. Next, verify the particulate filter is clean. After that, remove the rear flap and confirm the pump's electrical connector is properly connected to the printed circuit board. If these steps don't resolve the issue, the pump may be faulty and require replacement. Finally, the pump may be disabled; try switching the instrument off and then on again to re-enable it.

  If your E Instruments Measuring Instruments shows unreliable values on the analysis screen, there might be several reasons. Start by checking that the sensors are correctly installed via the sensor diagnostics menu. Then, inspect all joints and the hose for leaks in the sample probe connection. If those aren't the issue, the pump may be faulty and need replacement. As a last resort, the instrument itself might be faulty, requiring service center repair.
