INTRODUCTION

With the MC-380XCA moisture-measuring instrument,

EXOTEK INSTRUMENTS has introduced a hand-held moisture-measuring unit,

incorporang electronic circuitry perfected over years of development and

praccal applicaons with the latest technology.

It is easy to determine moisture content in wood and building materials

with the contact measurement procedure without destroying the material.

Reliability, durability and a high standard of accuracy are assured by

modern, digital and analogue components built to cope with the stress

of everyday use.

The seng of wood-groups and building material groups combined with

an automac zero-correcon, allow more accurate measurements on all

European as well as Tropical mbers, as well as on a great number of

building materials.

The Unique switchable dual Scanning Depth of 10 and 100 mm

makes it easy to determine Moisture Content even in ﬂoors with

built in Central Heang.

SWITCH-ON

By pressing this key once, if the device is oﬀ, the unit is

switched on.

SWITCH-OFF

By pressing this key once, if the device is on, the unit is

switched oﬀ.

Or: Automacally aer approx. 30 seconds if the value does not change.

ALARM FUNCTION

The MC-380XCA has the possibility to give an acousc

alarm in case of an user selectable alarm threshold is

reached or exceeded. This funcon is most useful for

sorng out mbers.

By pressing this key once, a -sign is indicated on the display. During this indica-

on, the key has to be pressed again. Now the actual threshold value (L6 – L30

or; L 0.6-L 3.0 or; 60-99% in RH mode) if the Building material group CC2 – b30

is selected) is indicated and the alarm funcon is acvated. In case this key is

pressed again, while the limit is indicated, the threshold value is being increa-

sed by 1% moisture in the range of 6 – 30% or If the CC2 to B30 is selected the

alarm threshold is increased with 0,1%. For RH mode the step increases by 1%

when the key is pressed). Aer 2 sec. the unit is ready to take measurements.

To turn oﬀthe alarm funcon, select only a diﬀerent funcon.

SENSOR SWITCHING

By pressing the L/S key once, a -sign is indicated on the display. Wait unl the

-sign is shown. During the -sign indicaon, the key has to be pressed again.

Now the previous selected sensor top ( ) or boom ( ) is

indicated. If during this display, this buon is pressed again, the device toggels

to the other sensor.

INSTALLING BATTERY

• Open the baery lid on the backside of the meter.

• Install a 9 volt L6R22.

• Close the lid.

A low voltage is indicated with to the le; upper side on the display

when the baery needs to be replaced. A new baery should be inserted to

achieve correct measuring results.

ENVIRONMENT PROTECTION

According to the regulaons for baery dispose, all

baeries must be returned to the trade or to baery

collecng points. You are not allowed to dispose baeries

through the household waste.

ONLY FOR EU COUNTRIES

Do not dispose of electrical tools together with household

waste material! In observance of European Direcve

2002/96/ EC on waste electrical and electronic equipment

and its implementaon in accordance with naonal law,

electric tools that have reach the end of their life must be

collected separately and returned to an environmentally

recycling facility.

SELECTION OF WOOD GROUPS OR BUILDING

MATERIAL GROUPS

Aer the unit has been switched on, the previous selected

sensor (top sensor with or boom sensor with

followed by the wood density 200-1180 kg/m3,

or building material CC2-b30 is indicated on the Display.

If this key is kept pressed, the group increases by itself

automacally while increasing the velocity, as longer it is kept pressed. Or aer

releasing and pressing the key E repevely, the wood group will increase by

20kg/m³ or the next Material group is selected. Aer 2 sec. the unit is ready

to take measurements. The indicated wood group is equivalent to the density

of the mber.

MEASURING WITH SPRING ELECTRODES

(penetraon depth up to 100 mm (4”))

Aer selecng the appropriate material-group the measuring springs must

be hold up in the air for automac 0-correcon.

The unit is ready for measuring aer about 2 sec.

Hold the spring electrodes without excessive force and in an approx. 40o

angel to the material. All of the 3 measuring springs must be in good contact

with the material to be measured. See Page 3 ﬁgure 1.

Measurements may be taken in diﬀerent spots of the material, or the

measuring springs could be slided across the material.

MEASURING WITH INTEGRATED

BOTTOM SENSOR (penetraon depth up to 10 mm (½”))

Aer selecng the appropriate material-group the boom of the unit must

be hold up in the air for automac 0-correcon.

The unit is ready for measuring aer about 2 sec.

Place the unit in upright posion onto the material to be measured or press

the boom of the unit against the material. See page 3 Figure 2.

The surface of the material that is to be measured have to be ﬂat and even.

Measurements may be taken in diﬀerent spots of the material.

SELECTING MEASURING MODE

: Measurement without hold funcon.

: Measurement with hold funcon

: Measured value is calculated into Relave

Humidity (only for material codes CC2, E2, E3 and E4).

: MC measurements are stored and the average value is calculated.

• “ : “ is showed in the lecorner of the display when a value is stored.

• The average value is ﬂashing on the display if the green buon is pushed.

• To reset the memory, push the green buon in for 5 seconds

(“0.00“ is ﬂashing).

EXPLANATION TO MEASURING FUNCTIONS:

F1 Measurement without Hold Funcon:

When the spring electrodes are moved over a surface, the MC-380XCA

connuously takes a new measurement. This funcon is used for fast

scanning of an area.

F2 Measurement with Hold Funcon:

The MC-380XCA only takes one measurement when the spring electrodes

touch a surface. The value is kept on the display aer the MC-380XCA

being removed from a surface. This is used for viewing the result where it

is diﬃcult to see the display during operaon. A new reading is taken when

the unit is placed on a surface again.

F3 Relave humidity:

To be used for building materials only not wood. The MC-380XCA automacally

calculates the Moisture content value (% H2O) into Relave air

Humidity (% RH). This funcon is used when relave humidity is a more

appropriate term.

F4 Memory/Average:

Up to 16 measurements can be stored in the memory. The MC-380XCA

then calculates the average of values stored in the memory.

THIN MATERIALS

For single materials, thinner than 5 mm, the sensivity of the meter is

normally not enough even with the boom sensor. To obtain a more accurate

measuring result we recommend measurements in a pile without

air spaces between the single parts and with a minimum thickness of 15

mm for the pile.

BASE

With material thickness < 50 mm the base material is very important To

Avoid a metal base. The best results are achieved if the material to be

measured is held into the air. Polystyrene material with a minimum thickness

of 20 (8”) cm can also be used when using the Measuring Springs.

It is suﬃcient with 2.5 cm (1”) of polystyrene mateial if the internal (boom)

sensor is used.

WET SURFACES

In case of material with a wet surface a PVC-foil can be used between

the material and measuring springs. For the Internal (boom sensor) a

PVC foil is not necessary.

When examining wood, make sure that measurements are carried out

in accordance with its ﬁbre direcon – otherwise the measured values

will be too low. The measuring direcon is correct when the wood ﬁbre

direcon is parallel to the indicator (see below).

REFERENCE MEASUREMENT

How to locate moist and leakage:

1. Set the Material code to 200 or CC2

2. Hold the spring electrodes or the boom sensor to a surface you know is dry

3. The received value corresponds to a “dry material” and could be used as

reference value

4. Now it is possible to locate moist and leakage using the reference value

5. By moving the measurement springs over the surface you could quickly

locate the leakage and ﬁnd out about the extent of the moist damage
