7 Maintenance
7.1 Battery Replacement

The TG Series is powered by three (3) 1.5V 'AAA' batteries.

The batteries are located in a tray housed inside the meter handle. To access the battery
tray, unscrew the cap at the bottom of the meter handle.

Slide the battery tray out of the handle, noting the tray orientation.

Replace the batteries observing correct polarity.

Slide the battery tray back into the handle in the original orientation.

Screw the cap back onto the handle.
7.2 Calibration
The meter is calibrated at the factory prior to shipment. If calibration is required please contact
a local FLIR service center. The TG Series is not user‐serviceable and should only be calibrated
by trained, qualified FLIR personnel.
7.3 Cleaning
Wipe the housing with a dry or damp cloth as needed. Use a high quality lens wipe to remove
dirt or smudges from the meter lenses and display window. Please do not use abrasives or
solvents to clean the meter housing, lenses, or display window.
