Tool Specifications
Inserting/Replacing the Battery
Alkali-manganese batteries are recommended for the
measuring tool.
To open the battery lid 14, press the latch 15 in the
direction of the arrow and fold up the battery lid.
Insert the supplied battery. Pay attention that the
polarity is correct, according to the representation on
the inside of the battery lid.
The battery indicator h always indicates the current
battery status:
• Battery fully charged
• Battery has 2/3 of its capacity or less
• Battery has 1/3 of its capacity or less
• Please change battery
❏ If the measuring tool is not used for a long
period of time, the battery must be
removed. The battery can corrode or discharge
itself over long periods.
Initial Operation
❏ Protect the measuring tool against mois-
ture and direct sun light.
❏ Do not subject the measuring tool to
extreme temperatures or variations in tem-
perature. In case of large variations in
temperature, allow the measuring tool to
adjust to the ambient temperature before
switching it on. In case of extreme temperatures
or variations in temperature, the accuracy of the
measuring tool and the display indication can be
impaired.
❏ Use or operation of transmitting systems,
such as WLAN, UMTS, radar, transmitter
masts or microwaves, in the close proximity
can influence the measuring function.
Switching On and Off
❏ Before switching the measuring tool on,
make sure that the sensor area 12 is not
moist. If required, dry the measuring tool using a
soft cloth.
❏ If the measuring tool was subject to an
extreme temperature change, allow it to
adjust to the ambient temperature before
switching on.
To switch on the measuring tool, press the On/Off
button 5.
To switch off the measuring tool, press the On/Off
button 5 again.
When no button on the measuring tool is pressed for
approx. 5 minutes and when no objects are detected,
the measuring tool automatically switches off to save
the battery.
Switching the Display Illumination
On/Off
The display illumination can be switched on/off with
display-illumination button 6.
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 off, indication a appears on the display.
