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. Intuitively the Up Arrow symbolizes 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.
ZERO CORRECTION MODE: (TL1-R Model Only)
Note: Corrections made will offset temperature over the entire range of the device.
1. Simultaneously press the function and on/off button. Release when ‘AdJ’ is displayed to enter zero correction mode.
2. While in zero correction mode, press and hold the power button to select ‘UP’, ‘dn’, ‘SAVE’, ‘no SAVE’ or ‘CAnC’.
3. If ‘UP’ is selected, the temperature can be adjusted up by pressing the function button.
4. If ‘dn’ is selected, the temperature can be adjusted down by pressing the function button.
5. If ‘CAnC’ (cancel) is selected, the instrument is still in zero correction mode and further adjustments can be made.
6. To save and exit after corrections has been made, hold the power button until ‘SAVE’ is displayed.
7. To exit without any zero correction changes, hold the power button until ‘no SAVE’ is displayed.
8. The instrument will return to normal operation.
9. To momentarily view the zero correction from the normal menu, hold the function button and release when ‘ZERo’ is
displayed.
