6. Electrical Connection
6.1 Mains Operation
Attention: When using a power supply unit please note that
operating voltage has to be 10.5 to 12 VDC. Do not apply over
voltage!! Simple 12 V-power supplies often have excessive no-
load voltage. We, therefore, recommend using regulated voltage
power supplies. Trouble-free operation is guaranteed by our
power supply HND-Z002. Prior to connecting the plug power
supply with the mains supply make sure that the operating voltage
stated at the power supply is identical to the mains voltage.
 Treat device and probes carefully. Use only in accordance with above
specification (do not throw, hit against etc.). Protect plugs and sockets from
soiling.
 To disconnect sensor plug do not pull at the cable but at the plug.
 When connecting the probe, the plug will slide in smoothly if plug is entered
correctly.
 Selection of Output-Mode: The output can be used as serial interface or as
analogue output. This choice has to be done in the configuration menu.

„Func-Stor“: Storing Single Measurements
7.3 Some Basics of Precision Material Moisture Measuring
7.3.1 Moisture Content u and Wet-Basis Moisture Content w
Depending on the Application one of the two units is necessary.
Carpenters, joiners and the like commonly use the moisture content u (sometimes
referred to as MC). When evaluating firewood, wood chips etc., wet basis moisture
content w is needed.
The instrument can be configured to both of the values. Please refer to chapter
“configuration“.
Moisture content u or MC (relative to dry weight) = dry basis moisture
content (mind the arrow at left bottom!)
The unit is %, sometimes used: % MC.
The unit expresses the moisture content like calculated below:
Moisture content u [%] = (weightwet - weightdry) / weightdry *100
Or: Moisture content u [%] = (weightwater) / (weightdry) *100
weightwet: weight of the wet material
weightwater: weight of water in the wet material
weightdry: oven-dry weight of material
Example: 1kg of wet wood, which contains 500g of water, has a moisture
content u of 100%

HND-F205
page 12 HND-F205 K06/0522
Wet-Basis Moisture Content w (relative to total weight, mind the arrow at left
bottom!)
The wet-basis moisture content expresses the ratio of the mass of water to the
total mass of the substance. The ratio is represented by the following equation
(the unit is % as well):
wet-basis moisture w[%] = (weightwet - weightdry) / weightwet *100
Or: wet-basis moisture w[%] = (weightwater) / weightwet *100
Example: 1kg of wet wood, which contains 500g of water, has a moisture
content u of 50%
7.3.2 Special Features of the Device
466 wood specimens and 28 building materials are stored directly in the
memory of the device:
Thus, more exact measurements could be reached than with common devices
with group selections would ever reach. Even the usage of complex conversion
tables for building materials won’t be necessary any more!
Example: Common wood-moisture-measuring-devices use one single group for
spruce and oak, in reality the deviation of these characteristic curves is more than
3 %! (Base for this statement is complex statistical surveys, considered measuring
range 7-25 %). This random error will not occur for the whole HND-F-series; with
the help of individual characteristic curves highest resolution is achieved.
Extreme wide measuring range: 0-100.0 % (depending on characteristic curve)
percent by weight in wood.
Moisture estimation: Additionally, to the measuring value, individual moisture
estimation will be displayed simultaneously.
7.3.3 Auto-Hold Function
Particularly when measuring dry wood, electrostatic charges and other similar
noise could dither the measuring value. With activated auto-hold function the
device will acquire an exact measuring value automatically. During that, the device
could be put down to avoid noise through discharge of the clothing etc. After
having acquired the measuring value, the display will change to ‘HLD’: The value
will be frozen as long as a new measuring is initiated by pressing button 6 (store).
Attention: If the logger is switched on (‘Func CYCL’ or ‘Func Stor’),
the auto-hold function can not be used. The device works like it is
set to Auto-HLD = off.

HND-F205
HND-F205 K06/0522 page 13
7.3.4 Automatic Temperature-Compensation ('Atc')
Exact temperature compensation is important for a reliable wood-moisture-
measuring. These devices feature a high-quality thermocouple-input for type k
thermocouples. Thus, you could connect common surface-temperature-probes –
The needed measuring-time ‘afield’ will be drastically lowered compared to
common (non-surface-) temperature-probes
The used temperature-value therefor is:

Atc on Temperature-probe

Manual input of temperature: shortly press
Temp-Button, then use  (button 2) or 
(button 5) to input the temperature, confirm
selection with ‘Store‘(button 6)
Attention: When connecting a probe that is non-insulated you must
have to observe not touching the wood or the electrodes nearby
the unshielded electrode. We suggest using our insulated probe
HND-FF10 (already included in standard case sets HND-FF12/-
FF13.

HND-F205
page 14 HND-F205 K06/0522
7.3.5 Measuring in Wood: Measuring with two measuring-pikes
Normally wood is measured with measuring-pikes. Used electrodes: impact-
electrode HND-FF02 or –FF03, reciprocating piston electrode HND-FF01. For
measuring wood, punch in the measuring-pikes across to the wood-grain, having
a good contact between the pikes and the wood (measuring along wood-grain
deviates minimal)
Select correct wood-sort (refer to Appendix A).
Ensure measuring the correct temperature
(see chapter 7.3.4 Automatic Temperature-Compensation ('Atc')).
Hint: The special HND-FF10 temperature-probe can be stuck into a hole
punched in with the electrode before (see picture on left). Now read the
measuring-value or when having activated the auto-hold-function initiate a
new measuring by pressing Store/ (button 6) .
The measured resistance will be extremely high when measuring dry wood
(<15 %) thus the measuring will need more time to achieve its final value.
Among other things static discharge could momentarily falsify the
measuring. Therefore beware of static discharge and wait long enough until
a stable measuring value is displayed (unstable: „%“ blinking) or use the
auto-hold-function (see chapter 7.3.3 Auto-Hold Function).
Most accurate measurements can be carried out within the range of
6 to 30 %.
Beyond this range the acquirable accuracy will lessen, but the device will
deliver reference values still sufficient for the practitioner.
Reciprocating
piston electrode
HND-FF01 with
temperature-
probe –FF10
It is measured between the measuring-pikes insulated among each other.
Requirements for an exact measurement:
 choose right correct place to measure: place should be free of irregularities like
resin–clusters, knurls, rifts, etc.
 choose correct measure depth: Recommendation for trimmed timber: punch in
the pikes up to 1/3 of the material thickness.
 Perform multiple measurements: the more measurements will be averaged, the
more exact the result will be.
 Pay attention to temperature-compensation: the temperature-probe should be
measuring the temperature of the moisture-measuring-place when measuring
with external temperature-probe (Atc on).
Without temperature-probe: let the device adapt to the temperature of the wood
(Act on) or enter the exact temperature manually (Act off).
Frequent sources of errors:
 Attention with oven-dried wood: the moisture dispersion may be irregular; often
in the core is more moisture than on the edge.
 Surface-moisture: The wood-edge could be more humid than the core if the
wood had been stored outside and e.g. was in rain.
 Wood preservative and other treatment could falsify the measuring.
 Fouling at the connections and round the pikes could result in erroneous
measurement, especially with dry wood.

HND-F205 K06/0522 page 15
7.3.6 Measuring other Materials
7.3.6.1 ‘Hard‘ Materials (concrete or similar): Measuring with brush-type
probes (HND-FF06 or HND-FF05)
Drill two holes with Ø6 mm (HND-FF05) or Ø 8 mm
(HND-FF06) at intervals of 8 to 10 cm into the material to
be measured. Do not use edgeless drills: the resulting
heat will evaporate the moisture which will result in faulty
measures. Wait for at least 10 min, blow out the holes to
clean them from dust. Apply conductivity compound on
the brush-type probes and stick them into the holes.
Choose correct material (see 7.3.4 Automatic
Temperature-Compensation ('Atc')), read the measuring
value. Observe that the holes dry out by-and-by, and the
device will measure a value too low, if you want to use
them several times.
This effect can be compensated by using conductivity
compound: insert profuse conductivity compound
between the holes and the brush-type probe, and let the
electrode stick in the hole for about 30 min before
measuring (with the device switched off). Temperature-
compensation plays no role when using the building
material measurin
g
.
Measuring concrete with brush
probe HND-FF06
7.3.6.2 ‘Soft‘ Materials (polystyrene or similar): Measuring with
measuring-pikes or -pins (HND-FF04)
Useable electrodes: impact electrode HND-FF02 or HND-FF03, reciprocating
piston electrode HND-FF01. Procedure as described in chapter measuring in
wood.
7.3.6.3 Measuring bulk cargo, bales and other special measures
Usable probes e.g. injection probe HND-FF14 or measuring pins –FF04 mounted
on –FF02 or –FF03.
Measuring of splints, wood chips, insulating material and similar:
When using injection probes or measuring pins oscillating movements have to be
avoided when pushing in the probes. Otherwise hollows between the probes and
the material may falsify the measuring. The material should be sufficiently
compressed. When in doubt, repeat the measuring a few times: the highest
measuring value is the most exact one. Especially when using the injection probe,
pay attention to having a foulness-free plastic insulator (situated immediately
underneath the measuring-pike).
Measuring bale of straw and hay bale: Always inject the electrodes from the
plain side of the bale, never from the round side, the probe can be inserted much
more slightly.

HND-F205
page 16 HND-F205 K06/0522
7.3.7 Measuring of materials, having no characteristic curves stored
Choose the representative universal material group „h.A“, „h.b“, „h.c“ und „h.dif a
conversion table exists.
Attention: The moisture evaluation wet/dry of these material groups
is only valid for wood! Please keep in mind the following when using
the temperature-compensation: Automatic temperature-
compensation should always be activated when measuring wood
(Act on), with all other materials the automatic temperature-
compensation should be switched off (Act off) and a manual
temperature of 20 °C should be entered.
Additionally, at HND-F205: The HND-F205 can store up to 4 additional user
characteristic curves. For this, the corresponding reference point measurements
for the respective material have to be carried out, from which the exact moisture
content has to be dedicated with the Darr-Probe or the CM-Method. The Results
can be stored in the device with the help of the GMHKonfig-Software, and can be
accessed by the device directly.
7.4 Hints for special functions
7.4.1 Moisture Estimation ('WET' - 'MEDIUM' - 'DRY')
Additionally, to the measuring value, individual moisture estimation will be
displayed simultaneously: The decision either wet or dry has no longer been
affiliated from literature and tables for the most applications. This moisture
estimation is only a guidance value; the final evaluation is depending on the
application of the material e.g:
Cement floor pavement ZE, ZFE
without additives: Readiness without floor heating at 2.3 % with
floor heating 1.5 %
Anhydrit floor pavement AE, AFE: Readiness without floor heating at 0.5 % with
floor heating 0.3 %*
Corresponding standards and instructions must be observed!
The device can only complement the skill of a tradesman or investigator but
cannot replace it!

HND-F205
HND-F205 K06/0522 page 17
7.4.2 Pre-selection of favourite Materials ('Sort')
A pre-selection of different materials (up to 8) can be selected from the menu for
an effective working with the device. For example, you can set the Menu Sort to 4
and save the desired materials in Sor.1, Sor.2, Sor.3 and Sor.4 if you only
measure 4 different materials. (Please refer to chapter 7.2 .Device Configuration.)
Only the 4 desired materials can be selected via the buttons up and down, when
exiting the menu, a changing during the measurement can be done comfortably.
All materials will be available when setting Sort to off. Sor.1 to Sor.4 will still be
available in the ‘background’, when setting the menu Sort to 4 the limited selection
of the 4 entered materials will be active again. If you only want to measure one
material: Set the menu Sort to 1, in this case you cannot change to another
material, thus a faulty operation is impossible.
7.4.3 Individually Programmable Characteristic Curves
There are 4 individually programmable characteristic curves integrated.
By using them, there can be used other material curves than the already
integrated ones.
The programmable curves can be read and programmed by the software
GMHKonfig.
As standard they are preset with the REF-curve. This curve is the base of the
determination of user specific curves.
Each curve is defined by a table with two columns (measuring value REF [%] /
display value [%]) with 20 rows.
The name of the curve, which is displayed in the lower display, can be set
individually. Characters, which cannot be displayed, are displayed as a space
character.
Each curve also contains limit values for wet and dry estimation.
As temperature compensation there is a choice between the standard
compensation for wood or linear compensation.
If there should be used no temperature compensation: Choose linear
compensation and enter 0 as compensation factor.
Linear temperature compensation:
MC compensated (T) = MC uncompensated*
(1+ compensation factor/10000 * (T-20 °C)
MC = moisture content

7.5 Operation of Logger
The device supports two different logger functions:
„Func-Stor“: Each time when „store“ (key 6) is pressed, a measurement
will be recorded.
„Func-CYCL“: Measurements will automatically be recorded at each
interval, which was set in the logger menu ‚CYCL‘ until the
logger will be stopped or the logger memory is full. The
recording is started by pressing „Store“ 2 seconds.
The logger records 1 measurement result each time. For the evaluation of the
data the software HND-Z034 (V1.7 or higher) has to be used. The software also
allows easy configuration and starting of the logger.
When the logger is activated (Func Stor or Func CYCL) the hold and auto hold
functions are no longer available, key 6 is solely used for the operation of the
logger functions.
7.5.1 „Func-Stor“: Storing Single Measurements
Each time when „store“ (key 6) is pressed a measurement and its time stamp will
be recorded. The recorded data can be viewed either in the display (when calling
the configuration an additional menu „REAd LoGG“ is displayed, see below) or by
means of the interface and a PC.
The logger stores the current measuring, independent from the stability of the
value.
The material curve can be altered like during a normal measuring.
Max. number of measurings: 99
A measuring contains: - current measuring value at the time of recording
- temperature value at the time of recording
- material curve at the time of recording
- time and date of the recording
After each recording „St. XX“ will be displayed for a short time. XX represents the
number of the recording.

HND-F205
HND-F205 K06/0522 page 19
When logger memory contains recordings already:
When „Store“ is pressed for 2 seconds, the choice for clearing the logger memory
will be displayed:
The selection can be made by  (key 2) and  (key 5). "Quit" (key 6) enters the
choice.
If the logger memory is full, the display will show:
Viewing Recorded Measurings
Within the „LoGG Stor“ function, the measurings can be viewed directly in the
display not only by means of a computer (like at „Func CYCL“): press 2 seconds
„Set“ (key 4): The first menu displayed now is „rEAd LoGG“ (read logger data).
After pressing  (key 3) the measurement recorded last will be displayed,
changing between the different data referring to the measurement also is done by

7.5.2 „Func-CYCL“:
Automatic Recording with selectable Logger-Cycle-Time
The Logger-Cycle-Time is selectable (see Device Configuration). For example
„CYCL“ = 1:00: A measuring is recorded after each 60 seconds.
Special feature of this logger function: The device will change to a ‘sleeping
state’ during the measurings (lower display shows a countdown to the next
measuring). Just before a new measuring should be recorded, the devices wakes
up and measures until a stable measuring value is evaluated. This value will be
stored, the device enters the sleeping state again. This procedure reduces the
battery consumption dramatically; with a fresh zinc carbon battery, the device is
capable of recording more than a month without an additional mains adapter.
When the cyclic logger contains data (independent if running or stopped), the
material cannot be changed.
The value measured during the last recording is shown in the upper display.
During the pauses no measuring is done!
An adequate message is stored, if no stable value could be measured during the
interval.
