Frequently Asked Questions - ScanTemp 485 31.1124 TFA

How to use the infrared thermometer?

Point the device at the object to be measured and press the measurement key. The temperature displays in one second. Ensure the target is larger than the measured spot (distance/spot ratio 12:1).

How to adjust emissivity?

Press the Mode key until "E" is displayed. Use the arrow keys to adjust emissivity from 0.10 to 1.00 in steps of 0.01. The default value is 0.95.

How to use the thermocouple probe?

Press the Mode key until "PRB" is displayed. Connect a type K probe into the socket on the side. The measuring range is -64 to +1400 °C.

What does the display "Hi" or "Lo" mean?

These messages indicate that the measured temperature exceeds the set alarm thresholds (HAL for high, LAL for low). Change the alarm values in the corresponding mode.

How to change the batteries?

Open the battery compartment at the back of the device. Replace the two used AAA batteries with new ones, respecting polarity. Use batteries of the same type and brand.

Why does the device not turn on?

Check that the batteries are installed correctly and that they are not discharged. If the problem persists, remove the batteries for one minute, then reinsert them to perform a reset.

How to activate the laser or backlight?

Hold down the measurement key to access settings. Use the Lock arrow key to turn the backlight on/off, and the °C/°F arrow key for the laser.

What is the accuracy of the device?

The manual does not specify the exact tolerance, but for infrared measurements, typical accuracy is about ±1.5°C or ±1.5% of reading (according to manufacturer standards). Refer to the complete documentation.

How to clean the lens?

Use a soft cotton cloth slightly moistened with water or medical alcohol. Wipe gently without scratching. Do not use abrasive products.

What to do in case of malfunction?

Perform a reset by removing the batteries for one minute. If the problem persists, contact TFA technical service. Do not attempt to repair or disassemble the device yourself.
