The calculation is indicated in the

measured-value lines A, and the

sum in the b.

After calculation of the sum,

further measured values can

be added to this result when

pressing the plus button 8 prior

to each measurement.

Notes on the addition:

– Mixed length, area/surface and

volume values cannot be added

together. For example, when a

length and area value are added,

“ERROR” briefly appears on

the display after pressing the

plus button 8. Afterwards, the

measuring tool switches back to

the last active measuring mode.

– For each calculation, the

result of one measurement is

added (e.g. the volume value);

for continuous measurements,

this would be the displayed

measured value in result line

b. The addition of individual

measured values from the

measured-value lines a is not

possible.

SUBTRACTING MEASURED

VALUES

To subtract

measuring

values, press

minus button 5;

For confirmation,

“–” is indicated

on the display. The further

procedure is analog to “Adding

Measured Values”.

Working Advice

GENERAL INFORMATION

The reception lens 12 and

the laser beam outlet 11 must

not be covered when taking a

measurement.

The measuring tool must

not be moved while taking a

measurement (with the exception

of the continuous measurement

function). Therefore, place the

measuring tool, as far as this is

possible, against or on a firm

stop or supporting surface.

INFLUENCE EFFECTS ON THE

MEASURING RANGE

The measuring range depends

upon the light conditions and the

reflection properties of the target

surface. For improved visibility

of the laser beam when working

outdoors and when the sunlight

is intense, use the laser viewing

glasses 17 (accessory) and the

laser target plate 18 (accessory),

or shade off the target surface.
