Why won't my Riken Keiki SD-1 turn on?
- C
  Chad BarnesAug 22, 2025
  If your Riken Keiki Gas Detector won't turn on, there are several potential causes. First, ensure the wiring is correctly connected and the terminal plate is properly attached. Also, check for any abnormalities or momentary blackouts in the power supply system, ensuring the rated voltage is supplied, and inspect the UPS, power supply line filter, and insulation transformer. Finally, examine the detector's wiring and related devices for any cable issues such as open circuits, disconnections, or short circuits.

  Kyle VazquezSep 3, 2025
  If your Riken Keiki Gas Detectors are displaying sensor abnormalities (E-1), verify the sensor cable is securely fastened to the terminal plate. Perform a zero adjustment; if the problem continues, replace the sensor. If zero drift caused by environmental changes or aging deterioration is out of the range of zero follower, replace the sensor with a new one.

  If your Riken Keiki Gas Detectors aren't powering on, check the wiring and ensure it's correctly connected. Also, confirm that the terminal plate is properly connected. Verify that the detector is receiving the rated voltage, and inspect the UPS, power supply line filter, and insulation transformer. Finally, check the detector's wiring and related devices for any cable abnormalities such as open circuits, disconnections, or short circuits.

  Rachel WilliamsAug 31, 2025
  If your Riken Keiki Gas Detectors system shows system abnormalities (E-9), ensure the detector is receiving the correct rated voltage by checking the power supply. If the issue persists, the problem may be internal. Also, verify the external output cable is correctly connected; if not needed, add resistance to the terminal. For internal failures, please contact our overseas sales department or local representatives.

Why do Riken Keiki SD-1 Gas Detectors have a slow response?
- J
  James AndradeAug 30, 2025
  If your Riken Keiki Gas Detectors are responding slowly, it might be because the sensor sensitivity has deteriorated. In this case, you should replace the sensor with a new one.

What causes system abnormalities E-9 on Riken Keiki Gas Detectors?
- M
  Megan ManningAug 29, 2025
  If your Riken Keiki Gas Detectors show a 'System abnormalities E-9' error, ensure the detector is receiving the rated voltage by checking the power supply. If the voltage is correct, the issue might be due to abnormalities of ROM, RAM, or EEPROM inside the detector; in this case, please contact our overseas sales department or local representatives.

Why is sensitivity calibration impossible on Riken Keiki Gas Detectors?
- M
  margaretchaseAug 27, 2025
  If you're unable to calibrate the sensitivity of your Riken Keiki Gas Detectors, it could be due to an improper calibration gas concentration. Make sure you are using the correct calibration gas. Another potential cause is deteriorated sensor sensitivity, which would require replacing the sensor.

How to fix sensor abnormalities E-1 on Riken Keiki Gas Detectors?
- D
  dpenaAug 27, 2025
  If your Riken Keiki Gas Detectors display a 'Sensor abnormalities E-1' error, it could be due to a few reasons. First, check that the sensor cable is securely fastened to the terminal plate. It could also be due to zero drift caused by environmental changes or aging. In this case, perform a zero adjustment. If the problem continues after the zero adjustment, the sensor may be faulty and needs replacement.

Why does the reading on Riken Keiki SD-1 keep rising or dropping?
- J
  Julie SpencerAug 26, 2025
  If the reading on your Riken Keiki Gas Detectors rises or drops and stays that way, it could be due to several reasons. One possibility is drifting of the sensor output, in which case you should perform a zero adjustment. Another reason could be the presence of interference gas, which requires an interference gas test. A slow leak of the gas to be detected may also be the reason. Environmental changes can also cause this issue, so performing a zero adjustment (AIR adjustment) may help.

What to do if Riken Keiki SD-1 alarm with no gas leak?
- P
  patricia57Aug 23, 2025
  If your Riken Keiki Gas Detectors trigger a gas alarm when there's no leak, here's what might be happening: * **Interference Gas:** The detector may be reacting to other gases, including solvents, so an interference gas test should be conducted. * **Noise Disturbance:** External noise can cause false alarms. Try turning the detector off and on again. If this happens frequently, take steps to reduce noise. * **Sudden Environmental Changes:** Rapid changes in temperature can affect the detector's readings. Environmental changes should be eliminated.
