Technical Data
- The working range may be reduced by unfavorable environmental conditions (e.g. direct sunlight).
- At 20–25 °C
- The values stated presuppose normal to favorable environmental conditions (e.g. no vibration, no fog, no smoke, no direct sunlight). Extreme fluctuations in temperature can cause deviations in accuracy.
- Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.
The serial number (12) 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 batteries to operate the
measuring tool.
To open the battery compartment cover (6), press the locking mechanism (7) and
lift open the battery compartment cover. Insert the batteries.
When inserting the batteries, ensure that the polarity is correct 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 measuring 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.
- Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries 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 (14) 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 (8) on the guide rail (15) of
the rotating mount (14) 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 (18),
- On metallic surfaces using the magnets (17).
- Keep your fingers away from the rear side of the magnetic accessory while attaching the accessory to sur-faces. The strong pulling force of the magnets may jam your fingers.
Operation
Starting Operation
-
Protect the measuring tool from moisture and direct sunlight.
-
Do not expose the measuring tool to any extreme temperatures or fluctuations in temperature. For example, do not leave it in a car for extended periods of time. If it has been subjected to significant fluctuations in temperature, first allow the measuring tool to adjust to the ambient temperature and then always carry out an accuracy check before continuing work (see “Accuracy Check of the Measuring Tool”, ).
The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature. -
Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences (see “Accuracy Check of the Measuring Tool”, ).
-
Switch the measuring tool off when transporting it. The pendulum unit is locked when the tool is switched off, as it can otherwise be damaged by big movements.
Switching On/Off
To switch on the measuring tool, slide the on/off switch (9) to the On
position (for working with the pendulum lock) or to the On position (for
working with automatic levelling). As soon as it is switched on, the measuring
tool emits laser beams from the outlet apertures (1).
- Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).
- To switch off the measuring tool, slide the on/off switch (9) to the Off position. The pendulum unit is locked when the tool is switched off.
- Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam.
If the maximum permitted operating temperature of 50 °C is exceeded, the tool shuts down to protect the laser diode. Once it has cooled down, the measuring tool is operational again and can be switched back on.
Automatic Shut-Off
If no button on the measuring tool is pressed for approx. 120 min, the
measuring tool will automatically switch itself off to preserve battery life.
To switch the measuring tool back on after it has been automatically switched
off, you can either slide the on/off switch (9) to the “Off” position first
and then switch the measuring tool back on, or press either the laser point
mode button (4) or the laser line mode button (5).
Temporarily Deactivating Automatic Shut-Off
To deactivate the automatic shut-off function, hold down the laser line mode
button (5) for at least 3 s (with the measuring tool switched on). If the
automatic shut-off function is deactivated, the laser beams will flash briefly
as confirmation.
Note: If the operating temperature exceeds 45 °C, automatic shut-off can
no longer be deactivated.
To activate the automatic shut-off function, switch the measuring tool off and
on again.
Setting the Operating Mode
The measuring tool has several operating modes, which you can switch between
at any time:
-
Cross-line and point mode: The measuring tool generates a horizontal and a vertical laser line as well as two vertical laser points, one facing up, the other down. The laser lines cross at a 90° angle.
-
Horizontal line mode: The measuring tool generates a horizontal laser line in front of it.
-
Vertical line mode: The measuring tool generates a vertical laser line in front of it.
Positioning the measuring tool in the room displays the vertical laser line on the ceiling beyond the top laser point.
If the measuring tool is positioned directly against a wall, the vertical laser line almost encircles the entire space (360° line). -
Point mode: The measuring tool generates two vertical laser points, one facing up, the other down.
All operating modes, apart from point operation, can be selected with both automatic levelling or the pendulum lock.
Working with Automatic Levelling
If the measuring tool is outside of the self-levelling range, the laser lines
and/or points will flash quickly.
If, during work with automatic levelling, you switch to “working with pendulum
lock” mode (on/off switch (9) in position On), the first combination option
of this mode’s indicators is always activated.
Working with the pendulum lock
The laser lines continuously flash slowly in “working with the pendulum lock”
mode.
If, during work with pendulum lock, you switch to “working with automatic
levelling” mode (on/off switch (9) in position On), the first combination
option of this mode’s indicators is always activated.
Automatic Levelling
Working with Automatic Levelling (see figures B1–E1) Position the measuring
tool on a level, firm surface or attach it to the rotating mount (14).
For work with automatic levelling, slide the on/off switch (9) to the ” On”
position.
The automatic levelling function automatically levels irregularities within
the self-levelling range of ±4°. The measuring tool has been levelled as soon
as the laser beams stop flashing.
If automatic levelling is not possible, e.g. because the sur-face on which the
measuring tool stands deviates by more than 4° from the horizontal plane, the
laser beams will flash quickly.
If this is the case, set up the measuring tool in a level position and wait
for the self-levelling to take place. As soon as the measuring tool is within
the self-levelling range of ±4°, the laser beams will light up continuously.
In case of ground vibrations or position changes during operation, the
measuring tool is automatically levelled again. Upon levelling, check the
position of the laser beams with regard to the reference points to avoid
errors arising from a change in the measuring tool’s position.
Working with a pendulum lock (see figure F1)
For work with the pendulum lock, slide the on/off switch (9) to the ” On”
position. The pendulum lock indicator (3) lights up red and the laser lines
continuously flash slowly. For work with the pendulum lock, automatic
levelling is switched off. You can hold the measuring tool freely in your hand
or place it on a sloping surface. This means that the laser beams are no
longer levelled and no longer necessarily run perpendicular to one another.
Accuracy Check of the Measuring Tool
Influences on Accuracy
The largest influence is exerted by the ambient temperature. In particular,
temperature differences that occur from the ground upwards can refract the
laser beam.
In order to minimise thermal influences resulting from heat rising from the
floor, it is recommended that you use the measuring tool on a tripod. In
addition, position the measuring tool in the centre of the work surface,
wherever this is possible.
In addition to external influences, device-specific influences (e.g. falls or
heavy impacts) can also lead to deviations. For this reason, check the
levelling accuracy each time before beginning work.
First check the height accuracy and levelling accuracy of the horizontal laser
line, then the levelling accuracy of the vertical laser line.
Should the measuring tool exceed the maximum deviation during one of the
tests, please have it repaired by a Bosch after-sales service.
Checking the Height Accuracy of the Horizontal Line For this check, you will
need a free measuring distance of 5 m on firm ground between two walls
(designated A and B).
- Mount the measuring tool close to wall A on a tripod, or place it on a firm, level surface. Switch on the measuring tool. Select cross-line mode with automatic levelling.
- Aim the laser at the closer wall A and allow the measuring tool to level in. Mark the middle of the point at which the laser lines cross on the wall (point I).
- Turn the measuring tool 180°, allow it to level in and mark the point where the laser lines cross on the opposite wall B (point Ⅱ).
- Position the measuring tool – without rotating it – close to wall B, switch it on and allow it to level in.
- Align the height of the measuring tool (using the tripod or by placing objects underneath as required) so that the point where the laser lines cross exactly hits the previously marked point Ⅱ on wall B.
- Turn the measuring tool 180° without adjusting the height. Aim it at wall A such that the vertical laser line runs through the already marked point Ⅰ. Allow the measuring tool to level in and mark the point where the laser lines cross on wall A (point Ⅲ).The discrepancy d between the two marked points Ⅰ and Ⅲ on wall A reveals the actual height deviation of the measuring tool.
The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m
is as follows:
10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points Ⅰ and Ⅲ must
therefore amount to no more than 3 mm.
Checking the Level Accuracy of the Horizontal Line For this check, you will
need a free area of 5 × 5 m.
- Mount the measuring tool in the middle between walls A and B on a tripod, or place it on a firm, level surface. Select horizontal line mode with automatic levelling and al-low the measuring tool to level in.
- At a distance of 2.5 m from the measuring tool, mark the centre of the laser line on both walls (point Ⅰ on wall A and point Ⅱ on wall B).
- Set up the measuring tool at a 5 m distance and rotated by 180° and allow it to level in.
- Align the height of the measuring tool (using the tripod or by placing objects underneath as required) so that the centre of the laser line exactly hits the previously marked point Ⅱ on wall B
- Mark the centre of the laser line on wall A as point Ⅲ (vertically above or below point Ⅰ)
- The discrepancy d between the two marked points Ⅰ and Ⅲ on wall A reveals the actual horizontal deviation of the measuring tool.
The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m
is as follows:
10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points Ⅰ and Ⅲ must
therefore amount to no more than 3 mm.
Checking the Level Accuracy of the Vertical Line
For this check, you will need a door opening (on solid ground) which has at
least 2.5 m of space either side of the door.
- Place the measuring tool 2.5 m away from the door opening on a firm, flat surface (not on a tripod). Select vertical line mode with automatic levelling. Aim the laser line at the door opening and allow the measuring tool to level in.
- Mark the centre of the vertical laser line on the floor of the door opening (point Ⅰ), 5 m away on the other side of the door opening (point Ⅱ) and on the upper edge of the door opening (point Ⅲ).
The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m
is as follows:
10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points Ⅰ and Ⅲ must
therefore amount to no more than 3 mm.
Checking the Level Accuracy of the Vertical Line
For this check, you will need a door opening (on solid ground) which has at
least 2.5 m of space either side of the door.
- Place the measuring tool 2.5 m away from the door opening on a firm, flat surface (not on a tripod). Select vertical line mode with automatic levelling. Aim the laser line at the door opening and allow the measuring tool to level in.
- Mark the centre of the vertical laser line on the floor of the door opening (point Ⅰ), 5 m away on the other side of the door opening (point Ⅱ) and on the upper edge of the door opening (point Ⅲ).
- Rotate the measuring tool 180° and position it on the other side of the door opening, directly behind point Ⅱ. Allow the measuring tool to level in and align the vertical laser line in such a way that its centre passes through points Ⅰ and Ⅱ exactly.
- Mark the centre of the laser line on the upper edge of the door opening as point Ⅳ
- The discrepancy d between the two marked points Ⅲ and Ⅳ reveals the actual vertical deviation of the measuring tool.
- Measure the height of the door opening.
You can calculate the maximum permitted deviation as follows:
Doubled height of the door opening × 0.3 mm/m Example: At a door opening
height of 2 m, the maximum deviation amounts to
2 × 2 m × ±0.3 mm/m = ±1.2 mm. The points Ⅲ and Ⅳ must therefore be no further
than 1.2 mm from each other.
Checking Plumb Accuracy
For this check, you will need a clear measuring space on firm ground with a
distance of approx. 5 m between the floor and the ceiling.
- Mount the measuring tool onto the rotating mount (14) and place it on the floor. Select point mode and allow the measuring tool to level in.
- Mark the centre of the top laser point on the ceiling (point I). Also mark the centre of the bottom laser point on the floor (point II).
- Turn the measuring tool by 180°. Position it so that the centre of the bottom laser point falls onto the marked point II. Allow the measuring tool to level in. Mark the centre of the top laser point (point III).
- The discrepancy d between the two marked points Ⅰ and Ⅲ on the ceiling reveals the actual deviation of the measuring tool from the vertical plane.
You can calculate the maximum permitted deviation as follows:
Doubled distance between floor and ceiling × 0.7 mm/m Example: At a floor-to-
ceiling distance of 5 m, the maximum deviation amounts to
2 × 5 m × ±0.7 mm/m = ±7 mm. The points Ⅰ and Ⅲ must therefore be no further
than 7 mm from each other.
Working Advice
- Only the centre of the laser point or laser line must be used for marking. The size of the laser point/the width of the laser line changes depending on the distance.
Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable support surface for measuring.
Place the measuring tool with the 1/4″ tripod mount (10) on the thread of the
tripod (23) or a conventional camera tripod. Use the 5/8″ tripod mount (11) to
se-cure the measuring tool on a conventional building tripod. Tighten the
measuring tool using the locking screw of the tri-pod.
Roughly align the tripod before switching on the measuring tool.
Securing with the universal holder (accessory) (see figure G)
You can secure the measuring tool, for example, on vertical surfaces or
magnetizable materials using the universal holder (19). The universal holder
is also suitable for use as a floor stand and facilitates the height
adjustment of the measuring tool.
- Keep your fingers away from the rear side of the magnetic accessory while attaching the accessory to sur-faces. The strong pulling force of the magnets may jam your fingers.
Roughly align the universal holder (19) before switching on the measuring tool.
Working with the Laser Target Plate (see figure G)
The laser target plate (20) improves visibility of the laser beam in
unfavorable conditions and at greater distances. The reflective surface of the
laser target plate (20) improves visibility of the laser line. The transparent
surface enables the laser line to be seen from behind the laser target plate
.
Laser Goggles (Accessory)
The laser goggles filter out ambient light. This makes the light of the laser
appear brighter to the eye.
- Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
- Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.
Example Applications (see figures B2–F2, G and H) Examples of possible applications for the measuring tool can be found on the graphics pages.
