2.3.11  Erasing the Temperature Data from Memory

The user can erase all 100 temperature data points in
memory at any time by using the following procedure:

1.

Pull the trigger and press the 

key.  The 

icon

will appear.

2.

Press the 

and 

keys in rapid sequence.

The display freezes momentarily, and a beep 
sounds for about 1 second.  Now the memory is 
cleared.  The thermometer reverts to real time mode.

3.

After all data is erased from memory, press the 

key

to unlock the trigger.

NOTE

NOTE

If the 

icon disappeared, repeat 

Steps 1 and 2.

Erasing the temperature data does not erase or 
reset Emissivity, High and Low Alarm setpoints,
printing interval, and Ambient Target Temperature
compensation.
