1、 Daily inspection and cleaning

1. Visual inspection
   • Inspection contentIs there any crack, damage or corrosion on the shell, is the seal intact, and are the display screen and buttons functioning properly.
   • purposePrevent radiation leakage or water ingress into equipment to ensure safe operation.
   • frequencyCheck before and after each use.
2. Cleaning treatment
   • cleaning toolsWipe the casing and display screen with a clean and soft cloth, avoiding direct contact with sensitive parts with chemical solvents (such as alcohol).
   • PrecautionsBefore cleaning, ensure that the device is powered off to avoid static electricity damaging the internal circuits.

2、 Calibration and Calibration

1. periodic calibration
   • calibration cycleAccording to the frequency of device usage and environmental conditions, calibration is usually performed every 6 months to 1 year.
   • calibration methodUse standard radiation sources (such as Cs-137, Co-60) for calibration to ensure that the measured values are consistent with the standard values.
   • Record and archiveDetailed records of calibration dates, results, and adjustment parameters for easy traceability.
2. zero point calibration
   • operating stepsStart the device in a non radiative environment, adjust the zero offset, and ensure that the background radiation reading is zero.
   • frequencyPerform zero calibration before each use.

3、 Battery and Power Management

1. battery maintenance
   • Charging standardsUse the original charger to avoid overcharging or overdischarging, and charge the battery promptly when the battery level is below 20%.
   • Storage suggestionsWhen not in use for a long time, keep the battery level at around 50% and store it in a dry, cool place.
   • replacement cycleAccording to the type of battery (such as lithium battery) and usage, the battery is usually replaced every 2-3 years.
2. Power cord inspection
   • Inspection contentCheck if the power cord is damaged, if the connector is loose, and if the insulation layer is intact.
   • Treatment measuresReplace immediately upon discovery of damage to avoid electric leakage or short circuit.

4、 Sensor and detector maintenance

1. Detector cleaning
   • Cleaning MethodGently remove dust or dirt from the surface of the detector using compressed air or a soft bristled brush to avoid scratching sensitive components.
   • PrecautionsWear protective gloves when cleaning to avoid skin oil contamination of the detector.
2. Detector aging detection
   • detection methodRegularly test the response of the detector using a standard radiation source and compare it with the initial data.
   • Replace standardWhen the detector response drops by more than 10%, the detector needs to be replaced.
3. Shielding material inspection
   • Inspection contentWhether the shielding material (such as lead shielding) around the detector is intact, whether it is damaged or detached.
   • purposePrevent external radiation from interfering with measurement results.

5、 Environmental adaptability maintenance

1. Temperature and humidity control
   • scope of workEnsure that the device is used within the recommended temperature range (usually -10 ℃~50 ℃) and humidity range (usually 10%~90% RH).
   • Storage conditionsWhen storing for a long time, avoidharshTemperature and humidity to prevent equipment aging.
2. Dustproof and Waterproof
   • Protection levelAccording to the equipment protection level (such as IP65), avoid using it in environments that exceed its protection capabilities.
   • Treatment measuresIf the equipment is flooded, it should be immediately powered off and sent for repair to avoid damage to the internal circuit.

6、 Software and Data Management

1. Software Update
   • update frequencyRegularly check software updates released by manufacturers, fix known issues or enhance functionality.
   • PrecautionsBackup device data before updating to avoid data loss.
2. data backup
   • Backup methodRegularly export measurement data to external storage devices (such as USB drives, computers) to prevent data loss.
   • data securityEncrypt and store sensitive data to prevent leakage.

7、 Long term storage and transportation

1. Long term storage
   • storage conditionsStore the device in a dry, cool, and radiation free environment, avoiding direct sunlight or high temperatures.
   • Moisture prevention measuresPlace desiccants in the storage box to prevent the equipment from getting damp.
2. Transportation precautions
   • packaging requirementsUse original packaging or specialized transport boxes to ensure that the equipment is not subjected to vibration or impact during transportation.
   • Radiation protection signsPaste anti radiation signs on the transport box to remind relevant personnel to pay attention to safety.

8、 Professional maintenance and upkeep

1. Regular inspection
   • Inspection cycleAt least once a year, it should be sent for comprehensive testing and maintenance by professional institutions.
   • detection contentIncluding circuit testing, sensor calibration, functional testing, etc.
2. Fault handling
   • Common FaultsIf the device cannot be turned on, the measurement value is abnormal, the display screen is not showing, etc.
   • Treatment measuresImmediately stop using and contact the manufacturer or professional maintenance personnel for inspection to avoid disassembling the equipment and causing damage or radiation leakage.
