Operation

Start-Up

u Never leave the measuring tool unattended when switched on, and

ensure the measuring tool is switched off after use. Others may be

dazzled by the laser beam.

u Protect the measuring tool from moisture and direct sunlight.

u Do not expose the measuring tool to any extreme temperatures or

variations in temperature. For example, do not leave it in a car for ex-

tended periods of time. In case of large variations in temperature, allow

the measuring tool to adjust to the ambient temperature before putting it

into operation. The precision of the measuring tool may be compromised

if exposed to extreme temperatures or variations in temperature.

u Avoid subjecting the measuring tool to violent jolts and falls. Always

check the measuring tool before continuing work if it has been subjected

to severe external influences (see "Checking the Measuring Tool",

page14).

Switching On/Off

To switch on the measuring tool, press the on/off button (1). When the

measuring tool is switched on, the laser beam is switched on. The laser sym-

bol flashes on the display.

To switch off the measuring tool, press and hold the on/off button (1) for at

least three seconds.

If no button on the measuring tool is pressed for approx. 5 mins, the measur-

ing tool will automatically switch itself off to preserve battery life.

Measuring Process

A continuous measurement is performed after the measuring tool has been

switched on. Aim the laser beam at the target surface. The current measured

value (g) is shown on the bottom line of the display (see figure A). During

continuous measurement, the measuring tool can be moved relative to the

target and the current measured value (g) will be updated approx. every 0.5

seconds on the bottom line of the display (see figure B). You can, for ex-

ample, move a desired distance away from a wall while reading off the cur-

rent distance at all times. The laser symbol flashes on the display.
