What to do if Riken Keiki GX-3R Pro shows low battery voltage alarm ?
If your Riken Keiki Measuring Instruments device shows a low battery voltage alarm (), it means the battery is running low. To resolve this, turn off the device and either charge the battery in a safe place at ambient temperatures between 0 °C and +40 °C, or replace it with a new battery.
What to do if Riken Keiki GX-3R Pro Measuring Instruments turns off immediately after turning on ?
If your Riken Keiki Measuring Instruments device immediately turns off when you turn it on (), it's likely due to low battery levels. You should turn off the power and charge the battery in a safe place where the temperature is between 0 °C and +40 °C. Alternatively, you can replace the battery with a new one.
What to do if Riken Keiki GX-3R Pro Measuring Instruments indicates a sensor abnormality in measurement mode ?
If your Riken Keiki Measuring Instruments device is showing a sensor abnormality in measurement mode (), it indicates that the sensor sensitivity has degraded. Contact Riken Keiki to request a sensor replacement. If “FAIL” appears in place of a measured value when the power is turned on, press the MODE button to reset the alarm. The gas sensors other than the faulty sensor can still be used.
Why does the charge LED on my Riken Keiki GX-3R Pro Measuring Instruments flash green and orange?
If the charge LED on your Riken Keiki Measuring Instruments device flashes alternately green and orange, it means the temperature is not right for charging. Make sure you charge the device in a place where the temperature is between 0 °C and +40 °C.
What to do if Riken Keiki Measuring Instruments has abnormal operation?
If you're experiencing abnormal operation with your Riken Keiki Measuring Instruments, it might be due to disturbances from sudden static electricity. Try turning off the power and then turning it back on again.
What to do if air calibration is not possible on Riken Keiki GX-3R Pro Measuring Instruments ?
If air calibration is not possible on your Riken Keiki Measuring Instruments device and you see , ensure that the product is surrounded by fresh air. If the issue persists, the sensor sensitivity may have degraded, and you should contact Riken Keiki to request a sensor replacement.
Why bump testing is not possible in Riken Keiki GX-3R Pro?
If you cannot perform bump testing on your Riken Keiki Measuring Instruments device, it could be due to the bump test gas concentration setting differing from the concentration of the bump test gas supplied. Check to confirm that the bump test gas concentration setting matches the concentration of the bump test gas supplied. If the issue persists, the sensor sensitivity may have degraded, and you should contact Riken Keiki to request a sensor replacement.
What to do if span adjustment is not possible on Riken Keiki GX-3R Pro ?
If span adjustment is not possible on your Riken Keiki Measuring Instruments device and you see , first check that the calibration gas concentration setting matches the concentration of the gas supplied. If you are using ESR-A1CP H2, allow the unit to stand overnight or more in an environment with sufficient humidity and then perform gas calibration again. If the issue persists, the sensor sensitivity may have degraded, and you should contact Riken Keiki to request a sensor replacement.
Why does Riken Keiki Measuring Instruments trigger a gas alarm with no gas?
If your Riken Keiki Measuring Instruments device triggers a gas alarm even when there's no problem in the measuring environment, it could be due to the presence of interference gases. It is difficult to completely eliminate the effects of interference gases, so contact Riken Keiki for information on countermeasures, such as interference gas removal filters. Alternatively, it could be due to the effects of noise. Try turning the power off and then on again (restart). If similar symptoms recur frequently, take appropriate measures to address the noise source.
Why does the reading on my Riken Keiki GX-3R Pro rise (or drop) and remain unchanged?
If the reading on your Riken Keiki Measuring Instruments device rises (or drops) and remains unchanged, it could be due to sensor drift. Try performing an air calibration. It could also be due to the presence of interference gases. It is difficult to completely eliminate the effects of interference gases, so contact Riken Keiki for information on countermeasures, such as interference gas removal filters. It could also be due to slow leakage, which may lead to dangerous situations, so take the same action as for gas alarms. Finally, it could be due to environmental fluctuations, so try performing an air calibration.
