Assembly

Inserting/Replacing the Battery

Alkali-manganese batteries are recommended for the meas-

uring 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

f

If the measuring tool is not used for a long period of 

time, the battery must be removed. 

The battery can cor-

rode or discharge itself over long periods.

Operation

f

Protect the measuring tool against moisture and direct 

sun light.

f

Do not subject the measuring tool to extreme tempera-

tures or variations in temperature. In case of large var-

iations in temperature, allow the measuring tool to ad-

just to the ambient temperature before switching it on. 

In case of extreme temperatures or variations in tempera-

ture, the accuracy of the measuring tool and the display in-

dication can be impaired.

f

Use or operation of transmitting systems, such as 

WLAN, UMTS, radar, transmitter masts or microwaves, 

in the close proximity can influence the measuring 

function.

Initial Operation

Switching On and Off

f

Before switching the measuring tool on, make sure that 

the sensor area 12 is not moist. 

If required, dry the meas-

uring tool using a soft cloth.

f

If the measuring tool was subject to an extreme tem-

perature change, allow it to adjust to the ambient tem-

perature 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.
