How do I switch between Celsius and Fahrenheit?

Press the [UNITS ▼] button to toggle between °C and °F.

How do I use the Hold function?

Press [HOLD] to freeze the current reading on the display. Press again to release.

What thermocouples are included?

Two Type K thermocouples are included with the thermometer.

How do I measure the temperature difference between T1 and T2?

Press the [T1-T2] button repeatedly to cycle through T1, T2, and T1-T2 (difference) displays.

How long does the auto power off take?

The thermometer automatically shuts off after 15 minutes of inactivity.

How long does the backlight stay on?

The backlight turns off automatically after 30 seconds if no button is pressed.

What is the accuracy of the thermometer?

Accuracy varies with range and thermocouple type. For Type K between 0-1000 °C, it is ±0.5% + 1 °C. For Type J between 0-1000 °C, it is ±0.15% + 1 °C.

Can I measure temperatures above 1000 °C?

Yes, with a Type K thermocouple up to 1370 °C, but resolution above 1000 °C is 1 °C instead of 0.1 °C.

How do I clean the thermometer?

Wipe the thermometer with a dry cloth. Do not use liquids or harsh chemicals.
