[ON/CLEAR]
Turns the unit ON and clears
the display. Holding down the
[ON/CLEAR] key for 1.5 seconds 
also powers the unit off.
[CLOSE +]
Completes the Polygon or a 
2-Point Circle and displays the 
calculated area. Results are 
identifi ed as positive values. 
When measuring a Polygon, this 
key connects the last measured 
point to the start point.
[MEASURE]
Takes a measurement between 
points.
Important Notes 
regarding the
[ON/CLEAR] key:
If [ON/CLEAR] is pressed 
during measurement, 
the last measured point 
is undone and the 
previous measurement is 
displayed. A second press 
of [ON/CLEAR] ends the 
measurement (as if the 
[END]
key was pressed) and
clears the main display.
During an Arc or Circle 
measurement, however, 
a second press of [ON/
CLEAR]
exits the Arc
or Circle measurement 
mode, discarding any 
measured points.
Additionally, if an error 
message is displayed 
during a measurement, 
pressing [ON/CLEAR] 
clears the error message 
and displays the previous 
measurement.
