1. Identify the four thermocouple input ports at the top of the device.
2. Plug the K-type, J-type, or T-type thermocouples into the desired channels (T1, T2, T3, T4). Ensure the plugs are inserted firmly and with correct polarity.

The Landtek 4-Channel Thermocouple Thermometer is shown in use, with four K-type thermocouples immersed in separate glasses of water, displaying individual temperature readings on its screen.

6. Basiese werking

6.1 Krag aan/af

• Druk die Krag knoppie om die toestel aan te skakel.
• Druk en hou die Krag knoppie om die toestel af te skakel.
• 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 Temperatuureenheidkeuse (°C/°F)

• Druk die ° C / ° F. button to toggle between Celsius and Fahrenheit temperature units.

6.3 Thermocouple Type Selection (K/J/T)

• Druk die 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

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

6.5 Datavashouding

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

7. Gevorderde kenmerke

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 Alarminstellings

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.
