Assembly

Inserting/Replacing Batteries

It is recommended that you use alkaline manganese or rechargeable batteries to operate the measuring tool. To open the battery compartment cover (3), press the locking mechanism (4) and fold the battery compartment cover up. Insert the batteries/rechargeable batteries. When doing so, ensure that the polarity is correct and corresponds to the diagram on the battery compartment cover.

Battery Indicator

The battery indicator (f) always indicates the current battery status:

Indicator: Capacity
90–100 %
60–90 %
30–60 %
10–30 %
0–10 %
The empty battery indicator flashes. You can measure for approximately another 15–20 min from when the flashing begins until the tool shuts down.

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.

Operation

Starting Operation

Protect the measuring tool from moisture and direct sunlight.
Do not expose the measuring tool to any extreme temperatures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
Keep the supporting surfaces and contact edges of the measuring tool clean. Protect the measuring tool against shock and impact. Dirt particles or deformations can lead to faulty measurements.
Avoid hard knocks to the measuring tool or 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 and Calibration of the Measuring Tool”, page 15).

Switching On and Off

To switch the measuring tool on or off, press the on/off button (9).

If no button on the measuring tool is pressed for approx. 30 min or the grade of the measuring tool is not changed by more than 1.5°, then grade measurement and the display are automatically switched off to save the batteries.

Changing the Measuring Unit (see figure A)

You can change between the units of measure “°”, “%” and “mm /m” at any time. For this, press the button for changing the unit of measure (8) as many times as needed for the required unit of measure to be displayed in the indicator (c) or (b). The current measured value (e) will be automatically converted. The unit-of measure setting is retained when switching the measuring tool on or off.

Switching the Audio Signal On and Off

The audio signal can be switched on or off with the audio signal button (7). When the audio signal is switched on, the indicator for the audio signal (g) appears in the display.

When you switch on the measuring tool, the audio signal is switched on as standard.

Measured Value Indicator and Alignment Aids With each movement of the measuring tool, the measured value (e) is updated. If the measuring tool has been moved significantly, wait until the measured value no longer changes before taking note of the value. Depending on the position of the measuring tool, the measured value and the unit of measure are indicated in the display rotated by 180°. Thus, the indicator can also be read when working overhead. The measuring tool uses alignment aids (a) on the display to show in which direction it has to be tilted in order to reach the target value. In standard measurements the target value is the horizontal or vertical, in the Hold/Copy function it is the stored measuring value.

If the target value is reached, the arrows for the alignment aids (a) go out and, provided the audio signal is switched on, a continuous audio signal will be played.

Measuring Functions

Holding/Copying a Measured Value

With the button Hold/Copy (11), two functions can be controlled:

Hold a measured value, even if the measuring tool is subsequently moved (e.g. because the measuring tool is in a position in which the display is difficult to read);
Copy a measured value.

Hold function:

Briefly press the button Hold/Copy (11). The current measured value (e) is held on the display and stored, and the indicator H flashes.
Press the button Hold/Copy (11) again to end the hold function. The stored value is deleted. Normal measurement is continued.

Copy function:

Press and hold the button Hold/Copy (11). The current measuring value (e) is copied and the indicator H is shown continuously on the display.
Briefly press the button Hold/Copy (11). The stored measuring value (e) is shown on the display and the indicator H flashes.
Place the measuring tool in the location to which the measured value is to be transferred. When doing so, the alignment of the measuring tool is irrelevant. The alignment aids (a) show which direction the measuring tool has to be moved in to reach the grade you want to copy. When the stored grade is reached, an audio signal sounds and the alignment aids (a) go out.
Briefly press the button Hold/Copy (11) again to return to normal measurement. The indicator H is shown continuously on the display.
Press and hold the button Hold/Copy (11) to save a new value.
To delete a hold value, briefly press the on/off button (9).

Accuracy Check and Calibration of the Measuring Tool

**Checking the Measuring Accuracy (see figure B)

**

Check the accuracy of the measuring tool prior to critical measurements, after intense variations in temperature as well as after heavy impact.

Before measuring grades < 45°, the accuracy check should take place on a level and roughly horizontal surface; before measuring grades > 45°, on a level and roughly vertical surface.

Switch on the measuring tool and place it on the horizontal/vertical surface.

Select the measuring unit °(see “Changing the Measuring Unit (see figure A)”, page 14).

Wait for ten seconds and note down the measured value.

Rotate the measuring tool by 180° around its vertical axis. Wait again for ten seconds and note down the second measured value.

Calibrate the measuring tool only when the difference between both measured values is greater than 0.1°.

Calibrate the measuring tool in the position (vertical or horizontal), in which the difference of the measured values has been determined.

**Calibration for Horizontal Surfaces (see figure C)

**

The surface onto which you place the measuring tool must not deviate from the horizontal surface by more than 5°. If the deviation is greater, the calibration process is discontinued with the indicator ‑‑‑

Switch on the measuring tool and position it on the horizontal surface so that the spirit level for horizontal alignment (1) faces upwards and the display (5) faces you. Wait for ten seconds.
Then press the calibration button Cal (10) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis sothat the spirit level still faces upwards but the display (5) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (10) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for this supporting surface.
Afterwards you must calibrate the measuring tool for thopposite surface. Rotate the measuring tool around the horizontal axis so that the spirit level for horizonta lalignment (1) faces downwards and the display (5) faces you. Place the measuring tool on the horizontal surface. Wait for ten seconds.
Then press the calibration button Cal (10) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downwards but the display (5) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (10) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for both horizontal supporting surfaces.

Note: If the measuring tool is not turned around the axis shown in the figure in steps ➂ and ➆, then the calibration cannot be completed (CAL2 is not indicated in the display).

**Calibration for Vertical Surfaces (see figure D)

**

The surface onto which you place the measuring tool must not deviate from the vertical surface by more than 5°. If the deviation is greater, the calibration process is discontinued with the indicator ‑‑‑.

Switch on the measuring tool and position it on the vertical surface so that the spirit level for vertical alignment (6) faces upwards and the display (5) faces you. Wait for ten seconds.
Then press the calibration button Cal (10) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis so that the spirit level still faces upwards but the display (5) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (10) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for this supporting surface.
Afterwards you must calibrate the measuring tool for the opposite surface. Rotate the measuring tool around the horizontal axis so that the spirit level for vertical alignment (6) faces downwards and the display (5) faces you. Place the measuring tool against the vertical surface. Wait for ten seconds.
Then press the calibration button Cal (10) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downwards but th edisplay (5) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (10) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for both vertical supporting surfaces.

Note: If the measuring tool is not turned around the axis shown in the figure in steps ➂ and ➆, then the calibration cannot be completed (CAL2 is not indicated in the display).
