If the multifunctional radiation detector malfunctions, it is necessary to first investigate the basic problem according to the type of malfunction, and then further handle it based on the equipment structure and instructions. If it is hardware damage, professional maintenance should be contacted. The following are common faults and corresponding solutions:
Unable to power on
Check the battery: Confirm if the battery is fully charged, replace it with a new battery that meets the specifications, and check if the battery compartment contacts are oxidized. Use a cotton swab dipped in alcohol to wipe the contacts and restore conductivity.
Power switch malfunction: If the switch is loose or unresponsive, lightly press the switch to check for any jamming. If it is internal damage to the switch, contact the manufacturer to replace the switch components.
Equipment crash: Some detectors can pass throughPress and hold the power button for 10-15 secondsForce restart to eliminate temporary system malfunctions.
Automatically shut down after startup
Poor battery contact: Reinstall the battery and ensure that the battery compartment cover is tightly closed; If it is a rechargeable model, check if the charging interface is loose and try recharging.
Hardware overload: If the device automatically shuts down after detecting excessive radiation, it may be triggered by a protective mechanism and placed in a radiation free environment to cool down before restarting.
Data displayed as 0 or no change
Sensor obstruction: Check whether the radiation sensor probe of the detector is obstructed by foreign objects (such as protective film, dust), and clean the dust and stains on the surface of the probe.
Probe malfunction: If the probe connection wire is loose (split type detector), unplug and plug the connection wire again; If the probe is damaged, it needs to be returned to the factory for replacement of the sensor.
Mode error: Confirm whether the device is set to the correct detection mode (such as gamma ray, beta ray, X-ray mode), and match the mode for different radiation types.
Data values are abnormally high/low
Calibration failure: The multifunctional radiation detector needs to be calibrated regularly (usually once every 1-2 years). If it exceeds the calibration cycle, contact a professional organization for recalibration.
Environmental interference: Stay away from electromagnetic interference sources (such as mobile phones, microwave ovens, high-voltage electricity) and retest. Electromagnetic interference may cause false high values.
Unit setting error: Check if the unit displayed on the device is a commonly used unit (such as μ Sv/h, mGy/h). Incorrect unit switching can cause numerical cognitive bias.
