• Press the designated button to calculate and display the maximum (MAX), minimum (MIN), or hold the current reading.

5. പരിപാലനം

5.1 0-പോയിന്റ് കാലിബ്രേഷൻ

• It is recommended to perform a 0-point calibration monthly or whenever a zero shift is observed, to ensure measurement accuracy.
• Ensure the battery level is above 2 bars before initiating calibration.
• Place the unit in a clean air environment for a period after turning it on to allow its body temperature to slightly exceed the ambient temperature, which is crucial for accurate calibration.

5.2 താപനില നഷ്ടപരിഹാരം

• The device automatically compensates measured data within the temperature range of -20℃ to 50℃ to maintain accuracy.

5.3 വൃത്തിയാക്കൽ

• The device is designed to be dust-proof. For general cleaning, wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.

6. പ്രശ്‌നപരിഹാരം

6.1 Software Error

• If the unit crashes or turns off unexpectedly, it indicates a software error during operation.
• To reactivate the unit, press the On/Off button.

6.2 കുറഞ്ഞ ബാറ്ററി

• If the unit turns off automatically or displays a low battery warning, recharge it immediately. Refer to section 4.6 for battery management.
