5.2 BT-981D Industrial Thermometer
- Power On/Off: Press the trigger to turn the device on. It will automatically power off after a period of inactivity.
- Measurement: Aim the thermometer at the target surface and press the trigger. The temperature reading will appear on the display. Ensure the target spot is within the device's distance-to-spot ratio for accurate measurement.
- Unit Switching (°C/°F): Use the dedicated button on the device to switch between Celsius and Fahrenheit.
- Emissivity Adjustment: If applicable, adjust the emissivity setting to match the material being measured for improved accuracy. Refer to the BT-981D's specific manual for details on emissivity settings.
6. Maintenance
6.1 Cleaning
- Wipe the device surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Keep the sensor area of the BT-5800G and the lens of the BT-981D clean and free from dust or debris.
6.2 Storage
- Store the devices in a cool, dry place away from direct sunlight and extreme temperatures.
- If storing for extended periods, remove batteries from the BT-981D.
6.3 Sensor Lifespan (BT-5800G)
The electrochemical principle sensor in the BT-5800G has an expected lifespan of approximately two years. Regular calibration may be required to maintain accuracy over time.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low battery (BT-5800G), dead battery (BT-981D), incorrect battery installation | Charge BT-5800G, replace battery in BT-981D, check battery polarity. |
| Inaccurate readings | Sensor/lens obstruction, environmental interference, incorrect emissivity (BT-981D) | Clean sensor/lens, ensure stable environment, adjust emissivity for BT-981D. |
| Alarm not triggering | Alarm threshold set too high, alarm disabled | Adjust alarm threshold to a lower value, ensure alarm is enabled in settings. |
| Display not working | Low battery, device malfunction | Charge/replace battery. If issue persists, contact customer support. |
