General Operation
Single distance measurement
1) Switch on the laser beam by pressing the Measure Button.
2) Point the laser dot to the surface to be measured. (Distance is
measured from bottom of the tool).
3) Press the Measure Button once again. The measured distance will
be displayed.
4) Press the Power On/Off Button to switch off.
Continuous measurement
1) Press and hold the Measure Button for 2 seconds to activate
continuous measuring mode. The tool beeps during continuous
measure mode if beeper is turned on.
2) Press the Measure Button again to stop continuous measure.
(It does not matter if the Quick Measure is On or Off. It will always
switch to continuous measurement). During continuous measurement,
the distances are recalculated and displayed about 8 to 15 times per
second, depending upon the reflectivity of the target surface. When
continuous measure is stopped, the last valid distance measurement is
displayed on the result line.
Power on/off options
1) The Quick Measure is designed to allow quick measurements by
pressing the Measure Button to switch on the tool and activate the
laser. In this case, measurement is accomplished when the Measure
Button is pressed the second time.
2) It is also possible to use the power button to switch on the tool. In
this case, the Measure Button must be pressed once to activate the laser
and a second time to accomplish a measurement.
