What to do if the sample pump is running slowly on my E Instruments Measuring Instruments?
- O
  oliviaweberAug 14, 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.

Why are the values unreliable on the analysis screen of my E Instruments E4500-S Measuring Instruments?
- K
  Karen SampsonAug 17, 2025
  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.

What to do if analysis screen gives a flue gas temperature (Tf) error on E Instruments E4500-S?
- L
  Lori ChenAug 25, 2025
  If your E Instruments Measuring Instruments displays a flue gas temperature error on the analysis screen, first ensure the thermocouple is properly connected to the analyzer. If the issue persists, the thermocouple may be faulty and need to be sent with the probe to a service center. The sensor might have been exposed to temperatures beyond its operating range.

Why does the sensor diagnostics screen show an error after auto-calibration on my E Instruments Measuring Instruments?
- D
  Diane YoungAug 28, 2025
  If, after auto-calibration, the sensor diagnostics screen on your E Instruments Measuring Instruments displays an error for one or more sensors, it could be because the auto-calibration occurred while flue gas was being sampled. Also, the oxygen sensor might be faulty, incorrectly connected, or not connected at all. Please refer to sections 5.3, 5.4, and 6.6.
