Notes:
1. As soon as the TL3 is turned on, the minimum, maximum and average data is continuously updated. Wait 20 seconds after
power-on to allow collection of readings before viewing minimum, average and maximum.
Display Arrows
The Arrows on the left side of the screen will show you at a glance as to whether the reading is increasing, decreasing or has
stabilized. The Up Arrow indicates an increasing temperature, the Down Arrow a decreasing temperature and no arrows a stabilized
status.
Battery Check
When the voltage of the batteries is low, the device will indicate “Lo bAtt” on the display before resuming normal display functions.
Do not attempt to calibrate the instrument if the “Lo bAtt” has been displayed since the new calibration values may not be properly
stored to memory.
Error Codes
ErrHI indicates an over range reading, meaning the temperature at the sensor has risen above the specified limit of the unit. This also
may indicate an open-circuit condition in the unit which may require repair.
ErrLO indicates a below range reading, meaning the temperature at the sensor has dropped below the specified limit of the unit. This
also may indicate a short-circuit condition in the unit which may require repair.
CALIBRATION
Calibration service is available from ThermoProbe, Inc. and authorized distributors. Contact ThermoProbe, Inc. for requirements if
onsite calibration is desired.
AUTHORIZED REPAIR
It is recommended that service beyond the scope of this manual be performed by ThermoProbe, Inc. or one of its authorized
distributors.
