Brennenstuhl Moisture Detector MD: Operating Instructions

Operating Instructions

INTRODUCTION

This moisture meter is a useful instrument, for determining the

moisture content of wood or construction materials such as concrete,

tile, screed, plaster, carpets, etc. Prior to operational start of the

device, read the following instructions carefully and keep them for

future reference.

Operation

Note: Be aware that the probe tip can cause injuries if used incor-

attery indicator:

The battery indicator is displayed when the device is in use. The bat-

tery symbol with two full bars ( ) means the battery is full. The

battery symbol with one full bars and one empty bar ( ) means

the battery is half full. If the battery is empty, the battery symbol

appears with two empty bars ( ) and blinks. The device will then

turn off and the battery must be replaced.

Performing measurements:

1. Remove the protective cover and place it on the

underside of the device.

2.

Press and hold the on/off switch » « until the

display appears in the display window.

Select wood » « or construction materials » « by

pressing the selector button » «.

Insert the probe tip into the material to be tested (e.g.

wood) and read the value in the display window. At the

same time, an acoustic signal should sound. The higher

the tone, the higher the moisture content.

Press the »Hold«-button once » « to »freeze« the

display in the display window. This can be useful if you

wish to perform a reading in conditions of darkness or

poor visibility. The symbol » « will appear in the

display window and the reading will be displayed until

the »Hold«-button » « is pressed again.

Press down the »Hold«-button » « for longer than

3 seconds to turn the acoustic tone on or off.

SAMPLE USES

Locating a leak in the wall

Place the probe on the surface to be

tested. Take a reading and read the

value from the display window. Repeat

this procedure in various places. If the

readings get higher, then you are get-

ting closer to the leak. If the values stop

increasing, you’ve found the leak.

materials

e.g. concrete, tile, screed, plaster, carpets prior to

finishing.

Check the moisture content of wood

e.g. of firewood or wood as a building material

Determining the moisture content of soil

Use the setting for “construction materials”

IMPORTANT NOTICES

Place the probe tips on the surface

carefully, do not apply force.

Handle the device carefully when the protective cap

has been removed. The probes can cause injuries if

used improperly.

When measuring soil, you will get low

readings if the readings are only

taken at the surface and higher

readings the deeper you press the

probes into the soil. The measured

value will differ significantly if you

take readings in loose or tightly

packed flower garden soil.

If the probes are set on a metal or a conductive

surface, the maximum value of >>50<< or >>33<< will

appear in the display.

Metal

Keep the probes clean using a damp cloth and put

them back in the protective cap.
