• Preme o Poder botón para acender o dispositivo.
• Manteña premido o Poder botón para apagar o dispositivo.
• The device features an automatic power-off function to save battery. This can typically be disabled via the settings menu if continuous operation is required.

6.2 Selección da unidade de temperatura (°C/°F)

• Preme o ° C / ° F botón para alternar entre as unidades de temperatura Celsius e Fahrenheit.

6.3 Thermocouple Type Selection (K/J/T)

• Preme o ADJ > 2s TYPE button to cycle through K, J, and T thermocouple types. Ensure the selected type matches the connected probes for accurate readings.

6.4 Max/Min/Average Functions

• Preme o MAX/MIN button to display the maximum, minimum, and average temperature readings recorded during the current measurement session.

6.5 Retención de datos

• Preme o REC > 2s HOLD button briefly to freeze the current readings on the display. Press again to release and resume live readings.

7. Funcións avanzadas

7.1 ADJ Temperature Compensation

The ADJ compensation function allows for fine-tuning temperature readings to minimize errors caused by thermocouple wire variations or environmental factors. The compensation range is from -9 to 9 °C (-16 to 48 °F).

• Access the ADJ compensation setting through the device's menu.
• Adjust the compensation value as needed to match a known reference temperature.

7.2 Configuración da alarma

The thermometer features audible and visual alarms that activate when measured temperatures exceed user-defined high or low limits.

The thermometer's display highlights its visual and audible alarm features. The visual alarm is indicated by a flashing light, and the audible alarm provides a sound notification when temperature thresholds are exceeded. Default upper limit is 1300°C, lower limit is -200°C.

• Navigate to the alarm settings in the menu.
• Set the desired upper and lower temperature limits for each channel.
• When a limit is breached, the device will trigger a sound and/or a flashing light on the display.
