4. Operating Instructions

4.1 Power On/Off

• Press the Power button () to turn the device on.
• Press and hold the Power button for approximately 2 seconds to turn the device off.

4.2 Basic Temperature Measurement

Upon powering on, the device will display real-time temperature readings from the connected thermocouple probes on its LCD screen.

4.3 Unit Switching (°C/°F and K/J Type)

• To switch between Celsius (°C) and Fahrenheit (°F), press the °C/°F button.
• To switch between K-type and J-type thermocouple readings, press and hold the ADJ > 2s TYPE button for 2 seconds.

4.4 Max/Min/Average Value Display

• Press the MAX MIN button to cycle through Maximum, Minimum, and Average temperature readings for the active channels.
• Press the button again to return to real-time display.

4.5 Data Hold Function

• Press the REC > 2s HOLD button briefly to freeze the current readings on the display. The 'HOLD' indicator will appear.
• Press the button again to release the data hold and resume real-time display.

4.6 ADJ Temperature Compensation

This function allows for fine-tuning the temperature readings for calibration purposes.

• Press and hold the ADJ button.
• While holding, use the Up/Down arrow buttons (often integrated with MAX MIN) to adjust the compensation value. The compensation range is -9°C to +9°C.
• Release the ADJ button to save the setting.

4.7 Audible and Visible Alarm

The device can alert you when temperature readings exceed or fall below set thresholds.

1. Setting Alarm Thresholds: Refer to the user manual or software interface for detailed instructions on setting upper and lower alarm limits. Default values are typically 1300°C (upper) and -200°C (lower).
2. Alarm Indication: When an alarm condition is met, the indicator light on the device will flash, and an audible tone will sound.
