Troubleshooting – Causes and Corrective Measures
Cause
Corrective Measure
Symbol for temperature warning (thermometer) is shown in the display,
operation is not possible
Measuring tool not within the operating
temperature range between – 10 °C and
+40 °C.
Wait until the measuring tool has reached
the operating temperature
Battery indicator decreasing
Battery voltage decreasing (measure-
ment still possible).
Replace batteries/rechargeable batteries
Battery indicator empty, measurement not possible
Battery voltage too low
Replace batteries/rechargeable batteries
“Error” and “––––” indication in display
The angle between the laser beam and
the target is too acute.
Enlarge the angle between the laser beam
and the target
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
16
(ac-
cessory)
The laser beam outlet
13
or the reception
lens
12
are misted up (e.g. due to a rapid
temperature change).
Wipe the laser beam outlet
13
and/or the
reception lens
12
dry using a soft cloth
Calculated value is greater than 999 999

.
Divide calculation into intermediate steps
Unreliable measuring result
The target surface does not reflect cor-
rectly (e.g. water, glass).
Cover off the target surface
The laser beam outlet
13
or the reception
lens
12
are covered.
Make sure that the laser beam outlet
13
or the reception lens
12
are unobstructed
Measuring result not plausible
Wrong reference level set
Select reference level that corresponds
to measurement
Obstruction in path of laser beam
Laser point must be completely on target
surface.
