Assembly

Inserting/Replacing the Batteries
Using alkali-manganese or rechargeable batteries is recommended for operation of the measuring tool.

To open the battery lid 3, press on the latch 4 and fold the battery lid up. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery lid.

Battery Indicator
The rechargeable battery/battery indicator f always displays the current battery status:

The battery is over 90% charged

The battery is between 60% and 90% charged

The battery is between 30% and 60% charged

The battery is between 10% and 30% charged

The empty battery indicator flashes. The battery charge status is under 10%. You can measure for approximately another 15–20 minutes from when the flashing begins until the tool shuts down.

Always replace all batteries/rechargeable batteries at the same time. Do not use different brands or types of batteries/ rechargeable batteries together.

• Remove the batteries/rechargeable batteries from the measuring tool when not using it for longer periods.
  When storing for longer periods, the batteries/rechargeable batteries can corrode and self-discharge.

Operation

Initial Operation

1. „ Protect the measuring tool against moisture and direct sun light.
2. „ Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired.
3. „ The contact surfaces and contact edges of the measuring tool must be clean. Protect the measuring tool against impact and shock. Debris particles or deformations can lead to faulty measurements.
4. „ Avoid heavy impact to or dropping down of the measuring tool. After severe exterior effects to the measuring tool, it is recommended to carry out an accuracy check (see "Checking the Measuring Accuracy") each time before continuing to work.

Switching On and Off
Press the "ON/OFF" switch 9 to switch the measuring tool on or off.

If no button on the measuring tool is pressed for approx. 30 mins 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 battery.

Changing the Unit of Measure (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 often as required until the desired setting is displayed in indicator b/c. The current measuring value is automatically converted.

The unit-of-measure setting is retained when switching the measuring tool on or off.

Switching the Audio Signal On/Off
The audio signal can be switched on/off with the audio signal button 7. When the audio signal is switched on, indicator g appears in the display.

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

Measured-value Indication and Alignment Aids
For each movement of the measuring tool, the measured value is updated. After moving the measuring tool to any extent, wait until the measured value no longer changes before reading 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 indication can also be read for overhead work.

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.

When the target value is reached, the arrows of the alignment aids a go out and a continuous audio signal sounds when the audio signal is switched on.

Measuring Functions
Holding/Copying a Measured Value

Two functions can be controlled with the "Hold/Copy" button 11:

• Holding ("Hold") of a measured value, even when the meas-uring tool is moved afterwards (e.g., because the measuring tool is in a position in which the display cannot be read);
• Copying ("Copy") of a measured value.

"Hold" function:

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

"Copy" function:

• Long press the "Hold/Copy" button 11. The current measuring value e is copied and indicator "H" is shown continuously on the display.
• Briefly press the "Hold/Copy" button 11. The stored measuring value e is shown on the display and indicator "H" flashes.
• Place the measuring tool in the location to which the meas-uring value is to be transferred. When doing so, the alignment of the measuring tool is irrelevant. The alignment aidsa 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 "Hold/Copy" button 11 again to return to normal measurement. Indicator "H" is shown continuously on the display.
• Long press the "Hold/Copy" button 11 to store a new value.
• To delete a "Hold" value, briefly press the "ON/OFF" button.

Checking the Measuring Accuracy (see figure B)

Check the accuracy of the measuring tool each time before using, after extreme temperature changes as well as after heavy jolts or impact.

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

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

Wait for 10 s and note down the measured value.

Rotate the measuring tool (as shown in the figure) by 180° around its vertical axis. Wait again for 10 s and note down the second measured value.

• „ Calibrate the measuring tool only when the difference between both reading 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 line by more than 5°. If the deviation is greater, the calibration process is discontinued with the indication "---" .

1.  Switch the measuring tool on and place it onto the horizontal surface in such a manner that the spirit level 1 faces upward and the display 5 faces you. Wait for 10 s.
2. ‚ Then press the "Cal" calibration button 10 until "CAL1" appears briefly on the display. Then the measuring value will flash on the display.
3. ƒ Turn the measuring tool by 180° around the vertical axis so that the spirit level still faces upward, but the display 5 faces away from you. Wait for 10 s.
4. „ Then press the "Cal" calibration button 10 again. "CAL2" will be shown briefly on the display. Then the measuring value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for this supporting surface.
5. … Afterwards you must calibrate the measuring tool for the opposite surface. For this, turn the measuring tool around its horizontal axis in such a manner that the spirit level 1 faces downward and the display 5 faces you. Place the measuring tool onto the horizontal surface. Wait for 10 s.
6. † Then press the "Cal" calibration button 10 until "CAL1" appears briefly on the display. Then the measuring value will flash on the display.
7. ‡ Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downward but the display 5 is facing away from you. Wait for 10 s.
8. ˆ Then press the "Cal" calibration button 10 again. "CAL2" will be shown briefly on the display. Then the measuring 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 ƒ and ‡, 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 line by more than 5°. If the deviation is greater, the calibration process is discontinued with the indication "---".

1.  Switch the measuring tool on and place it against the vertical surface in such a manner that the spirit level 6 faces upward and the display 5 faces you. Wait for 10 s.
2. ‚ Then press the "Cal" calibration button 10 until "CAL1" appears briefly on the display. Then the measuring value will flash on the display.
3. ƒ Turn the measuring tool by 180° around the vertical axis so that the spirit level still faces upward, but the display 5 faces away from you. Wait for 10 s.
4. „ Then press the "Cal" calibration button 10 again. "CAL2" will be shown briefly on the display. Then the measuring value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for this supporting surface.
5. … Afterwards you must calibrate the measuring tool for the opposite surface. For this, turn the measuring tool around its horizontal axis in such a manner that the spirit level 6 faces downward and the display 5 faces you. Place the measuring tool against the vertical surface. Wait for 10 s.
6. † Then press the "Cal" calibration button 10 until "CAL1" appears briefly on the display. Then the measuring value will flash on the display.
7. ‡ Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downward but the display 5 is facing away from you. Wait for 10 s.
8. ˆ Then press the "Cal" calibration button 10 again. "CAL2" will be shown briefly on the display. Then the measuring 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 ƒ and ‡, then the calibration cannot be completed ("CAL2" is not indicated in the display).
