Troubleshooting –

Causes and Corrective Measures

The measuring tool is outside the

operating temperature range from

–14°F to +122°F (in the function

continuous measurement up to

+104°F).

Wait until the measuring tool has

reached the operating temperature.

CAUSE CORRECTIVE MEASURE

Temperature warning indicator (f) flashing; measurement not

possible

“ERROR” indication in the display

Addition/Subtraction of measured

values with different units of

measure.

Only add/subtract measured values

with the same units of measure.

The angle between the laser beam

and the target is too acute.

Increase the angle between the

laser beam and the target.

The target surface does not reflect

correctly (e.g. water, glass).

Cover off the target surface.

The target surface reflects

too intensely (e.g. a mirror) or

insufficiently (e.g. black fabric), or

the ambient light is too bright.

Work with the laser target plate 18

(accessory).

The laser beam outlet 11 or the

reception lens 12 are misted up

(e.g. due to a rapid temperature change).

Wipe the laser beam outlet 11 and/

or the reception lens 12 dry using a

soft cloth.

Calculated value is greater than

999999 m/m

Divide calculation into intermediate

steps.

Unreliable measuring result

The laser beam outlet 11 or the

reception lens 12 are covered.

Make sure that the laser beam

outlet 11 or the reception lens 12

are unobstructed
