1. Safety instructions
This chapter gives general rules which must be followed
and observed if the product is to be handled safely.
Avoiding personal injury/damage to equipment
iDo not use the measuring instrument and sensors to
measure on or near live parts.
iNever store the measuring instrument/probe together
with solvents and do not use any desiccants.
Product safety/preserving warranty claims
iOperate the product only within the parameters
specified in the Technical data.
iAlways use the product properly and for its intended
purpose. Do not use force.
iDo not expose handles and feed lines to temperatures in
excess of 70 °C unless they are expressly permitted for
higher temperatures. Temperatures given on
probes/sensors relate only to the measuring range of the
sensors.
iOpen the product only when this is expressly described
in the documentation for maintenance and repair
purposes.
Carry out only the maintenance and repair work that is
described in the documentation. Follow the prescribed
steps when doing so. For safety reasons, use only
original spare parts from testo.
Ensure correct disposal
iSend the product back to testo at the end of its useful
life. We will ensure that it is disposed of in an
environmentally friendly manner.

2. Intended purpose
Use the product only for those applications for which it was
designed. Ask testo if you are in any doubt.
The product was designed for the following
tasks/applications:
·Fast and non-destructive evaluation of material moisture
courses in woods and building materials.
Does not replace reference methods such as CM
method or Darr-Wäge (dry-and-weigh) method.
The probe is not calibratable.
· For connection to testo 635-1 (Art.-no. 0560 6351) and
testo 635-2 (Art.-no. 0560 6352).
The product must not be used in the following areas:
· Areas at risk of explosion.
Materials subject to electrical voltage.
Electric sshock!
If in doubt, check whether the materials are
energized before the measurement (e.g. in the
event of water damage in walls)

3.1 Overview
Overview
Contact plates
Handle
Connection cable
3.2 Humidity measurement
procedure
The non-destructive stray field measurement uses the
ability of water molecules to dampen and thus change
electromagnetic fields. The electric field penetrates the
material via the contact plates and creates a measuring
field with a depth of approx. 5 cm.
The following factors can influence the measurement result:
Factors Ideal condition
Measurement depth Material thickness > 5 cm (> 2“). Caution: The upper
layers of the material influence the measurement result
more than the deeper layers.
Material surface As level as possible as contact plates should lay flat
against it.
Material properties As homogeneous as possible with no air pockets.
Moisture distribution As even as possible.
Metals and electric fields None, if possible.

4. Measuring
²Taking aammeasurement:
The instrument is switched on and is in measurement
view.
The correct material was selected in the instrument,
see instruction manual for the measuring instrument.
Selectable materials:
Display Material
A.screed Anhydrite screed
C.screed Cement screed
Limestone Limestone
Concrete Concrete
I. brick High-insulating brick
Sol. brick Solid brick
Hwlumber Hardwood lumber
Swlumber Softwood lumber
Gas concr Gas concrete
Chipboard Chipboard
Service Testing characteristic. Not for on-site measurements!
iHold probe horizontal to contact surface. Slowly
increase contact pressure to 1 to 3 kg (2.2 to 4.4lb)
until a stable value is shown.
In order to be able to evaluate a moisture course, several
measurements at different positions or at different times
are necessary.
In drying processes, the displayed measurement values
can in individual cases also be negative. This occurs as
a result of the material composition and the different
moisture gradients. When negative measurement values
are displayed, the drying process is nearly finished, i.e.,
the more negative the values, the drier the material.
For better assessment of the contact pressure, the
probe can initially be pressed against a scale.

5. Care and maintenance
±Cleaning tthe hhousing:
iClean the housing with a moist cloth (soap suds) if it
is dirty. Do not use aggressive cleaning agents or
solvents!
±Changing ccontact pplates:
The outer contact plates can be exchanged by the
customer
iIf necessary: Order exchange set via customer
service.
