Ultrasonic measuring tool 0520
INTRODUCTION
● This tool is intended for measuring distances indoors by
means of ultrasonic waves
● When used properly, this tool easily and accurately
measures length, surface and volume
● Carefully read this instruction manual as well as the
warning label on the tool, before you use the tool 1
● Pay special attention to the safety instructions and
warnings; failure to follow these may result in
serious (eye) injury
● Save this instruction manual for future reference

USE
● On/off
- switch on the tool by pressing "Power" button
- ambient temperature in °C is shown on display
- switch off the tool by pressing "Power" button again
- the tool automatically switches off after 30 seconds of
inactivity
● Mounting of battery 4
! ensure that the tool is switched off
- remove cover P
- insert 9V battery (pay attention to correct polarisation)
- mount cover P
- when battery level is low, symbol 5 will appear in
display
! change battery in time, otherwise faulty
measurements may occur
- always remove the battery from the tool, if the tool is
not used for a long period
● Metre/feet conversion
- measurements are in metres/centimetres by default
- press button E 3 for converting metres/centimetres
into feet/inches
- setting will not change as long as battery is not
removed from tool
● Operating the tool 6
- press "Power" button
- select measurement mode (button F, G, or H)
- place rear edge of the tool on the starting-point of the
measurement
! aim the tool towards the target surface at a right
angle (use bubble levels M 3)
- a laser "target" 7 is projected on the target surface
as an indication of where the ultrasonic signal is
reflected by the measured object
! do not look into the laser beam
! do not point the laser beam at persons or animals
- press "Read" button; measured distance appears on
top line of display
! keep in mind that the tool measures from its rear
(the tool length is included in the measuring result)
● Instructions for proper measurement 6
! do not move the tool during measuring
! do not measure beyond the specified
measurement range (0,5 - 15 m)
! ensure that there are no obstructions within the
conical expanding sound range
- large, hard and flat surfaces give the most accurate
results
- place a piece of cardboard in front of the target
surface, when measuring small, soft or irregular
surfaces (such as carpets, curtains, coarse wallpaper,
etc.)
