can corrode and self-discharge during prolonged storage in

Operation

Starting Operation

Protect the measuring tool from moisture and direct sun-
u
light.
Do not expose the measuring tool to any extreme temper-
u
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.
Keep the supporting surfaces and contact edges of the
u
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.
u
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", page 15).
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. 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 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 button Hold/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 button Hold/Copy (11). The current meas-
ured value (e) is held on the display and stored, and the in-
dicator H flashes.
– Press the button Hold/Copy (11) again to end the hold func-
tion. The stored value is deleted. Normal measurement is
continued.
