the CLR key (short press) or until the meter is powered OFF. 

Continuous Distance Measurements (with MAX-MIN)

 

This mode of operation is useful for determining the shortest 
and longest distances from a given point. The meter can be 
moved to various targets while the primary display (bottom) 
updates with each new measurement. The MIN and MAX values 
are displayed dynamically in auxiliary displays above the primary 
display. 

1.

 

Press the MEASURE key to switch the meter ON. 

2.

 

Press and hold MEASURE for 3 seconds to begin a continuous 
measurement session. The laser pointer will stay ON in 
continuous mode. 

3.

 

The meter will beep with each new automatic measurement 
update (approx. every one half second). 

4.

 

The MIN reading will be indicated (example below, left) and 
will update each time a lower reading (< displayed MIN 
reading) is encountered. 

5.

 

The MAX reading (example below, right) will be indicated and 
will update each time a higher reading is encountered. 

 

6.

 

The actual reading will be indicated on the primary display.
