Protection rating
IP 54 (dust and splash-
proof)
A) The working range may be reduced by unfavourable environ-
mental conditions (e.g. direct sunlight).
B) At
20–25
°C
C) The values stated presuppose normal to favourable environ-
mental conditions (e.g. no vibration, no fog, no smoke, no direct
sunlight). Extreme fluctuations in temperature can cause devi-
ations in accuracy.
D) Only non-conductive deposits occur, whereby occasional tem-
porary conductivity caused by condensation is expected.
The serial number
(13)
on the type plate is used to clearly identify
your measuring tool.
Assembly
Inserting/Changing the batteries
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
To open the battery compartment cover
(7)
, press the lock-
ing mechanism
(8)
and lift open the battery compartment
cover. Insert the batteries.
When inserting the batteries, ensure that the polarity is cor-
rect according to the illustration on the inside of the battery
compartment.
If the batteries become weak, the battery warning
indicator
(2)
will flash green. The laser lines will also flash for
approximately five seconds every ten minutes. The measur-
ing tool can still be operated for approximately one hour
after the first flash. If the batteries drain completely, the
laser lines will flash one more time just before automatic
shut-off.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
u
Take the batteries out of the measuring tool when you
are not using it for a prolonged period of time.
The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Working with the RM 1 rotating mount
(see figures A1–A3)
You can use the rotating mount
(15)
to rotate the measuring
tool 360° around a central, always visible plumb point. This
enables you to set up the laser lines without having to
change the position of the measuring tool.
Place the measuring tool with the guide groove
(9)
on the
guide rail
(16)
of the rotating mount
(15)
and slide the
measuring tool all the way onto the platform.
To disconnect the measuring tool, pull it off the rotating
mount in the opposite direction.
Rotating mount positioning options:
– Standing on a flat surface,
– Screwed to a vertical surface,
– On metallic ceiling strips using the ceiling clip
