1. Safety instructions 19

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

i Do not use the measuring instrument and sensors to

measure on or near live parts.

i Never store the measuring instrument/probe together

with solvents and do not use any desiccants.

Product safety/preserving warranty claims

i Operate the measuring instrument only within the

parameters specified in the Technical data.

i Always use the measuring instrument properly and for its

intended purpose. Do not use force.

i Do 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.

i Open the instrument 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

i Take faulty rechargeable batteries/spent batteries to the

collection points provided for them.

i Send 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 purpose20

2. Intended purpose

This chapter gives the areas of application for which the
product is intended.

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 instrument is not calibratable.

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. Product description22

3.2 Voltage supply

Voltage is supplied by means of a 9 V monobloc battery
(included in delivery) or rechargeable battery. It is not
possible to run the instrument from the mains supply or
charge a rechargeable battery in the instrument.

3.3 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 (2”).

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.

6. Measuring26

²

Taking aa mmeasurement:

 The instrument is switched on and is in measurement

view.

i Hold instrument horizontal to contact surface. Slowly

increase contact pressure to 1 to 3 kg 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
instrument can initially be pressed against a scale.

²

Keep rreading, ddisplay mmaximum/minimum vvalue:
The current reading can be recorded. The maximum and

minimum values (since the instrument was last switched
on) can be displayed.

i Press several times until the desired value is

displayed.

- The following are displayed in turn:

· Hold: The recorded reading

· Max: Maximum value

· Min: Minimum value

· Current reading

²

Resetting tthe mmaximum/minimum vvalues:

Switching the instrument off and on again resets the
maximum and minimum values.
