Conectando termopares
The K102 supports two K-type thermocouples. Connect your K-type thermocouple probes to the T1 and/or T2 input jacks located at the top of the device. Ensure a secure connection for accurate readings.
Instruções de operação
Ligar/desligar
Pressione o O button to turn the thermometer ON. Press and hold the O button for approximately 2 seconds to turn it OFF.
Fazendo medições de temperatura
- Ensure thermocouples are properly connected to the T1 and/or T2 inputs.
- Ligue o dispositivo usando o O botão.
- The display will show the current temperature readings for T1 and T2 (if both are connected).
- Place the thermocouple probe(s) at the desired measurement point.
- Allow a few moments for the reading to stabilize on the display.
Alternar unidades de temperatura (°C/°F)
Pressione o ° C / ° F button to toggle between Celsius (°C) and Fahrenheit (°F) temperature scales.
Função MAX/MIN
Pressione o MÁX/MÍN button to cycle through the maximum, minimum, and current temperature readings recorded since the device was powered on or the function was last reset. To reset the MAX/MIN values, press and hold the MÁX/MÍN button until the display clears or resets.
Função HOLD
Pressione o SEGURAR button to freeze the current temperature reading on the display. This is useful for recording readings in unstable environments. Press it again to release the hold and resume live readings.
Relative Measurement (REL)
The relative measurement function allows you to set the current reading as a reference point (zero) and display subsequent measurements as a deviation from this reference. Press the REL button to activate this mode. The display will show '0.0' and then subsequent readings will be relative to this zero point. Press it again to exit relative mode.
Temperatura Diferencial (T1-T2)
When two thermocouples are connected to both T1 and T2 inputs, the device can display the temperature difference between T1 and T2. This mode is typically accessed by cycling through display options using a dedicated button or automatically displayed alongside T1 and T2 readings.
Manutenção
Limpeza
Limpe o dispositivo com um pano macio e levemente úmidoamp cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the device is completely dry before storage or further use.
Substituição da bateria
When the low battery indicator appears on the display, replace the 9V battery as described in the "Installing the Battery" section under Setup.
Armazenar
Store the thermometer in a cool, dry place, away from direct sunlight and extreme temperatures. Remove the battery if storing for extended periods (e.g., more than one month) to prevent leakage and damage to the device.
Solução de problemas
| Problema | Possível causa | Solução |
|---|---|---|
| O dispositivo não liga. | Bateria descarregada ou instalada incorretamente. | Verifique a polaridade da bateria ou substitua-a por uma nova bateria de 9V. |
| Leituras imprecisas. | Faulty thermocouple, poor connection, or device needs calibration. | Check thermocouple connection. Test with a known good thermocouple. Refer to calibration instructions (if provided separately) or contact support. |
| "OL" or "---" displayed. | Temperature out of range, open circuit thermocouple, or faulty probe. | Ensure temperature is within the specified range (-200 to +1370 °C). Check thermocouple for damage or proper connection. Replace faulty probe if necessary. |
