Switching on and off
• To switch on, press the on/off
key [6] when the measuring unit
is switched off. To switch off,
press the on/off key [6] when
the measuring unit is switched
on.
Humidity level measurement
• Switch on the measuring unit by
pressing the on/off key [6]
• The measuring unit must be
calibrated each time it is switched
on. Hold the measuring unit in
the air for calibration so that
the humidity sensor [1] does not
touch any objects. The minimum
distance from any surface or
your hand to the ball head of the
humidity sensor [1] should be 8
to 10 cm
NOTE
If you have calibrated
the measuring unit for a
measurement, do not change
the position of the hand in
the subsequent measurement.
Measurement calibration and
measurement must be carried
out with the same hand position,
because a change in the position
of the hand, relative to the ball
head of the humidity sensor [1],
leads to measuring errors.
• The calibration must always
be carried out again after each
new switch-on as well as each
change of the measuring point or
the measured object!
• Hold the ball head of
the humidity sensor [1] at right
angles to the surface.
The display shows the measured
value (current humidity level
[18]).
• Move the measuring unit to take
measurements of a larger surface.
The LC display should show the
current measured value as well as
the maximum [16] and minimum
[15] measured values.
• If necessary, press the
MEAS
key [5] to freeze a value on
the display. “HOLD” [10] appears
on the display in addition
to the last measured value.
If the “HOLD” mode is not
terminated by pressing the
MEAS
key [5], the measured values
are shown on the LC display
for another 30 seconds before
the measuring unit switches off
automatically.
• Before this time has elapsed,
press the
MEAS
key (5) in “HOLD”
mode to exit “HOLD” mode and
perform further measuring
procedures.
• After finishing your
measurements, switch off the
measuring unit by pressing the
on/off key [6]. If the measuring
unit is not switched off, it will
automatically switch itself off
after a period of 10 minutes. To
do this, it must not be in “HOLD”
mode
NOTE
There is a 1/4" (6.3 mm) screw
terminal on the back of the
measuring unit for attaching
the measuring unit to suitable
holding devices such as tripods.
This allows measurements
to be taken on the stationary
measuring unit by dragging the
smaller part to be measured past
the probe.
NOTE
Measuring head may leave black
marks on light-coloured walls
or wallpaper. Please place the
measuring head carefully on
sensitive surfaces
measuring in a clearly dry area of
a similar or identical material. If
the subsequent measurements
are significantly higher than
the reference value, it can be
concluded that the measuring
ranges are wet. This method is
very well suited for assessing
water damage, locating leaks and
areas of high humidity • Press the
MEAS
key (5) to start
the calibration procedure. The
LC display shows “CA” during
calibration
• After calibration, the LC display
[2] shows the current humidity
level [18]. This calibration value
should be “0”. If not, switch off
the measuring unit and repeat
the calibration procedure after
switching it on again.
