Troubleshooting - Bosch GLR500 Instrucciones De Funcionamiento Y Seguridad

The rangefinder is not within the operating
temperature of – 10 °C to +50 °C (+14 °F to +122 °F).
(in the function continuous measurement
up to +40 °C (+104 °F).
Battery voltage decreasing (measurement still
possible)
Battery voltage too low
The angle between the laser beam and the target is
too acute.
The target surface reflects too intensely (e.g. a mirror)
or insufficiently (e.g. black fabric), or the ambient light
is too bright
The laser beam outlet
misted up (e.g. due to a rapid temperature change).
The calculated area or volume value is larger than
99990 ft 2 or ft 3 .
Addition/Subtraction of different types of
measurements
The target surface does not reflect correctly (e.g.
water, glass).
The laser beam outlet 27 or the reception lens 26 are
covered.
Wrong reference point set
Obstruction in path of laser beam
The rangefinder monitors the correct
mode for each measurement. When a
defect is determined, only the symbol
shown aside flashes in the display.
In this case, or when the above mentioned
corrective measures cannot correct an error, have
the measuring tool checked by an after-sales
service agent for Bosch power tools.

Issue
Temperature warning indicator (i) flashing;

Battery indication (f) appears
Battery indication (f) flashes, measurement not possible
The indications "Error" and "- - -" are indicated in the display

The indication "Error" flashes at the top in the display
Measuring result not plausible
Wait until the rangefinder has reached the
operating temperature
Replace batteries
Replace batteries

lens dry using a soft cloth
Divide calculation into intermediate steps
Only add/subtract of the same type
Cover off the target surface
Make sure that the laser beam outlet 27 or the
reception lens 26 are unobstructed
Select reference point that corresponds to
measurement
Laser point must be completely on target surface
Accuracy Check of the Rangefinder
The accuracy of the rangefinder can be checked as
follows:
• Select a permanently unchangeable measuring
section with a length of approx. 1 to 10 meters (3
to 33 feet); its length must be precisely known
(e.g. the width of a room or a door opening).
• Measure the distance 10 times after another.
The difference in values must not amount to more
than a maximum of ±1.5 mm (±1/16 in). Keep a
record of the measurements in order to compare
the accuracy at a later time.
