Frequently Asked Questions - TI219 Owon

How do I switch between Celsius and Fahrenheit?

Press and hold the °C/°F button for 2 seconds to toggle between units.

What does the low battery indicator mean?

When the battery icon appears, replace the two AAA batteries with new ones to ensure accurate readings.

How far away can I measure temperature?

The distance-to-spot ratio is 12:1. For example, at 12 cm distance, the measured spot is 1 cm in diameter.

Can I use this thermometer to measure body temperature?

No, this is a surface thermometer designed for objects, liquids, and ambient surfaces, not for medical use.

How do I clean the lens?

Gently wipe the lens with a soft, lint-free cloth. Do not use solvents or abrasive cleaners.

What does the laser do?

The laser helps you aim at the target. It is a Class II laser, safe under normal use but avoid direct eye exposure.

Why is my reading flashing?

Flashing may indicate an error or out-of-range measurement. Check the target temperature is within -50°C to 380°C.

Does the thermometer have an auto-off feature?

Yes, it automatically turns off after approximately 10 seconds of inactivity to save battery.

How do I get the maximum or minimum temperature reading?

Press the MAX/MIN button to cycle through current, maximum, and minimum recorded temperatures.

What is the emissivity setting?

The emissivity is fixed at 0.95, suitable for most common surfaces. For reflective surfaces, results may be inaccurate.
