A) Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected. B) Due to the lower voltage of the rechargeable batteries, the battery indicator will not display a full charge. The serial number(2) on the type plate is used to clearly identify your measuring tool. Assembly Inserting/Replacing Batteries It is recommended that you use alkaline manganese 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. In- sert the batteries/rechargeable batteries. When doing so, ensure that the polarity is correct and corres- ponds to the diagram on the battery compartment cover. Battery Indicator The battery indicator(f) always indicates the current battery status: Indic- ator Capacity 90–100 % 60–90 % 30–60 % 10–30 % 0–10 % The empty battery indicator flashes. You can measure for approximately another 15–20min from when the flashing begins until the tool shuts down. Always replace all the batteries at the same time. Only use bat- teries from the same manufacturer and which have the same ca- pacity. u Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries Bosch Power Tools 1 609 92A 58M | (28.11.2019)14 | English can corrode and self-discharge during prolonged storage in the measuring tool. Operation Starting Operation u Protect the measuring tool from moisture and direct sun- light. u Do not expose the measuring tool to any extreme temper- atures 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 temperat- ure. u 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. u 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 in- fluences (see "Accuracy Check and Calibration of the Measur- ing Tool", page15). Switching On and Off To switch the measuring tool on or off, press the on/off but- ton(9). If no button on the measuring tool is pressed for approx. 30min 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 (seefigureA) 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 sig- nificantly, wait until the measured value no longer changes be- fore 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 ro- tated by 180°. Thus, the indicator can also be read when work- ing 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 buttonHold/Copy(11), two functions can be con- trolled: – Hold a measured value, even if the measuring tool is sub- sequently moved (e.g. because the measuring tool is in a pos- ition in which the display is difficult to read); – Copy a measured value. Hold function: – Briefly press the buttonHold/Copy(11). The current meas- ured value(e) is held on the display and stored, and the in- dicatorH flashes. – Press the buttonHold/Copy(11) again to end the hold func- tion. The stored value is deleted. Normal measurement is continued. 1 609 92A 58M | (28.11.2019) Bosch Power ToolsEnglish | 15 Copy function: – Press and hold the buttonHold/Copy(11). The current measuring value(e) is copied and the indicatorH is shown continuously on the display. – Briefly press the buttonHold/Copy(11). The stored meas- uring value(e) is shown on the display and the indicatorH flashes. – Place the measuring tool in the location to which the meas- ured 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 buttonHold/Copy(11) again to return to normal measurement. The indicatorH is shown continuously on the display. – Press and hold the buttonHold/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 (seefigureB) Check the accuracy of the measuring tool prior to critical meas- urements, 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 measur- ing grades >45°, on a level and roughly vertical surface. Switch on the measuring tool and place it on the horizontal/ver- tical surface. Select the measuring unit ° (see "Changing the Measuring Unit (seefigureA)", page14). Wait for tenseconds and note down the measured value. Rotate the measuring tool by 180° around its vertical axis. Wait again for tenseconds and note down the second measured value. u 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 hori- zontal), in which the difference of the measured values has been determined. Calibration for Horizontal Surfaces (seefigureC) The surface onto which you place the measuring tool must not deviate from the horizontal surface by more than 5°. If the devi- ation is greater, the calibration process is discontinued with the indicator ‑‑‑. ➀ Switch on the measuring tool and position it on the hori- zontal surface so that the spirit level for horizontal align- ment(1) faces upwards and the display(5) faces you. Wait for tenseconds.

Then press the calibration buttonCal(10) for approx. twoseconds until CAL1 appears briefly on the display. Then the measured value will flash on the display. ➂ 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 tenseconds.

Then press the calibration buttonCal(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 sup- porting surface. ➄ 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 horizontal align- ment(1) faces downwards and the display(5) faces you. Place the measuring tool on the horizontal surface. Wait for tenseconds.

Then press the calibration buttonCal(10) for approx. twoseconds until CAL1 appears briefly on the display. Then the measured value will flash on the display. ➆ Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downwards but the dis- play(5) is facing away from you. Wait for tenseconds.

Then press the calibration buttonCal(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 hori- zontal supporting surfaces. Bosch Power Tools 1 609 92A 58M | (28.11.2019)16 | English 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 (seefigureD) The surface onto which you place the measuring tool must not deviate from the vertical surface by more than 5°. If the devi- ation is greater, the calibration process is discontinued with the indicator ‑‑‑. ➀ Switch on the measuring tool and position it on the ver- tical surface so that the spirit level for vertical align- ment(6) faces upwards and the display(5) faces you. Wait for tenseconds.

Then press the calibration buttonCal(10) for approx. twoseconds until CAL1 appears briefly on the display. Then the measured value will flash on the display. ➂ 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 tenseconds.

Then press the calibration buttonCal(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 sup- porting surface. ➄ 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 align- ment(6) faces downwards and the display(5) faces you. Place the measuring tool against the vertical sur- face. Wait for tenseconds.

Then press the calibration buttonCal(10) for approx. twoseconds until CAL1 appears briefly on the display. Then the measured value will flash on the display. ➆ Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downwards but the dis- play(5) is facing away from you. Wait for tenseconds.
