1 In General

1.1 Safety Instructions

This device has been designed and tested in accordance to the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and
special safety advises given in this manual will be adhered to when using it.

1. Trouble-free operation and reliability of the device can only be guaranteed if it is not subjected to any other climatic
conditions than those stated under “Specification”.

2. Transporting the device from a cold to a warm environment condensation may result in a failure of the function. In
such a case make sure the device temperature has adjusted to the ambient temperature before trying a new start­up.

3. The circuitry has to be designed most carefully if the device should be connected to other devices. Internal
connection in third party devices (e.g. connection GND and earth) may result in not-permissible voltages impairing
or destroying the device or another device connected.

4. Warning: Operating the device with a defective mains power supply (e.g. short circuit from mains voltage to output
voltage) may result in hazardous voltages at the device (e.g. at sensor socket)

5. Whenever there may be a risk whatsoever involved in running it, the device has to be switched off immediately and
to be marked accordingly to avoid re-starting. Operator safety may be a risk if:

- there is visible damage to the device

- the device is not working as specified

- the device has been stored under unsuitable conditions for a longer time
In case of doubt, please return device to manufacturer for repair or maintenance.

6. Warning: Do not use these product as safety or emergency stop device, or in any other application where failure of
the product could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and material damage.

7. Risk of injury! The used measuring heads are very sharp, use thoroughly during your measuring to eliminate a
possible risk of injury.

1.2 Operating And Maintenance

• Battery Operation
The battery has been used up and needs to be replaced, if and „bAt“ are shown in lower display. The device
will, however, continue operating correctly for a certain time.
The battery has been completely used up, if ´bAt´ is shown in the upper display.
The battery has to be removed, when storing device above 50°C.

Hint: We recommend to remove the battery if device is not used for a longer period of time! Risk of Leakage

• Mains Operation

Attention: When using a power supply unit please note that operating voltage has to be 10.5 to 12 V DC. Do not
apply over voltage!! Simple 12V-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 GNG10/3000.
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.

3 Some Basics Of Precision Material Moisture Measuring

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., the 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:

Or:

Moisture content u [%] = (weight

- weight

) / weight

Moisture content u [%] = (weight

Example: 1kg of wet wood, which contains 500g of water has a moisture content u of 100%

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[%] = (weight

Or: wet-basis moisture w[%] = (weight

Example: 1kg of wet wood, which contains 500g of water has a moisture content u of 50%

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 are complex statistical surveys, considered
measuring range 7-25%). This random error will not occur for the whole GMH38xx series, with the help of individual
characteristic curves highest resolution is achieved.

Extreme wide measuring range: 0-100% (depending on characteristic curve) percent moisture content in wood.
Moisture estimation: Additionally to the measuring value, an individual moisture estimation will be displayed

simultaneously.

3.3 Automatic temperature-compensation ('Atc')

An 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:

(already included in standard case sets SET38HF and SET38BF).

H60.0.12.6C-09 Operating Manual GMH3850 page 7 of 20

3.4 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.

3.5 Measuring In Wood: Measuring With Two Measuring-Pikes

Normally wood is measured with measuring-pikes. Used electrodes: impact-electrode GSE91 or GSG91, reciprocating
piston electrode GHE91. 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 3.3).
Hint: The special GTF38 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 3.4 Auto-Hold Function).

Reciprocating piston

electrode GHE91 with

temperature-probe GTF38

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 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.

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.

3.6 Measuring Other Materials

3.6.1 ‘Hard‘ Materials (concrete or similar): Measuring with brush-type probes (GBSL91 or GBSK91)

Drill two holes with Ø6mm (GBSK91) or Ø 8mm (GBSL91) at intervals
of 8 to 10cm 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 10min, 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 Appendix
B: Additional materials), 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 30min before
measuring (with the device switched off ). Temperature-compensation

Measuring with brush probe GBSL91

3.6.2 ‘Soft‘ Materials (polystyrene or similar): Measuring with Measuring-pikes or -pins (GMS 300/91)

Useable electrodes: impact electrode GSE91 or GSG91, reciprocating piston electrode GHE91.
Procedure as described in chapter measuring in wood.

plays no role when using the building material measuring.

H60.0.12.6C-09 Operating Manual GMH3850 page 8 of 20

3.6.3 Measuring bulk cargo, bales and other special measures

Usable probes e.g. injection probe GSF38 or measuring pins GMS 300/91 mounted on GSE91 or GSG91.

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 having a foulness-free plastic insulator (situated immediately
underneath the measuring-pike).
Measuring bale of straw and hay bale: Always inject the electrodes form the plain side of the bale, never from the
round side, the probe can be inserted much more slightly.

3.7 Measuring of materials, having no characteristic curves stored

Choose the representative universal material group „h.A“, „h.b“, „h.c“ and „h.d“(for example corresponding to A,B,C
and D of the GHH91) if 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 GMH3850: The GMH3850 can store up to 4 additional user characteristic curves. For this the
corresponding reference point measurements for the respective material has 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 .

4 Hints For The Special Functions

4.1 Moisture estimation ('WET' - 'MEDIUM' - 'DRY')

Additionally to the measuring value, an individual moisture estimation will be displayed simultaneously. 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%
Also firewood may be already usable while instrument still displays ‘wet’!
Corresponding Standards and Instructions must be observed!
The Device can only complement the skill of a tradesman or investigator but cannot replace it!

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 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. You only want to measure one material: set the menu Sort to 1 you cannot change to another material,
thus a faulty operation is impossible.

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 pre set 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 lower display, can be set individually. Characters which cannot be
displayed are displayed as a space character.
Each curve contains also 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 should be used: 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

H60.0.12.6C-09 Operating Manual GMH3850 page 9 of 20

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 GSOFT3050 (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.

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 with GSOFT3050-software.

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.

When logger memory contains recordings already:

When „Store“ is pressed for 2 seconds, the choice for clearing the logger memory will be displayed:

Clear all
recordings

The selection can be made by 5 (key 2) and 6 (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 4 (key 3) the measurement recorded last will be displayed, changing between the different data
referring to the measurement also is done by pressing 4.
Changing the measurement is done by pressing the keys 5 or 6.

Clear the last
recording

Clear nothing
(cancel menu)

H60.0.12.6C-09 Operating Manual GMH3850 page 10 of 20

5.2 „Func-CYCL“: Automatic Recording With Selectable Logger-Cycle-Time

The Logger-Cycle-Time is selectable (p.r.t. 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 count-down 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 been measured during the interval.

Max. number of measurings: 10000

Cycle time: 0:01...60:00 (minutes:seconds, min 1s, max 1h), selectable in the configuration

A measuring contains: - current measuring value at the time of recording

- temperature at the time of recording

Recording time: > 1 month (with output activated: OUT = SEr)

> 3 months (with output deactivated: OUT = off)
With mains adapter: limited just by memory and cycle time, up to 416 days

Starting a recording:

By pressing "Store" (key 6) for 2 seconds the recording will be initiated. After that the display shows ‘St.XXXX‘ for a
short time whenever a measuring is recorded. XXXXX is the number of the measuring 1..9999.

6 Output

The output can be used as serial interface (for GRS3100 or GRS3105 interface adapters) or as analogue output (0­1V). If none of both is needed, we suggest to switch the output off, because battery life then is extended.

6.1 Interface - Base Address ('Adr.')

By using an electrically isolated interface converter GRS3100, GRS3105 or USB3100 (accessory) the device can be
connected to a PC.
With the GRS3105 it is possible to connect up to 5 instruments of the GMH3000 family to a single interface (please
also refer to GRS3105-manual). As a precondition the base addresses of all devices must not be identical. In case
several devices will be connected via one interface make sure to configure the base addresses accordingly. In order to
avoid transmission errors, there are several security checks implemented (e.g. CRC).

The following standard software packages are available for data transfer:

! EBS9M: 9-channel software to record and display the measuring values
! EASYControl: Universal multi-channel software (EASYBUS-, RS485-, and/or GMH3000- operation possible)

for real-time recording and presentation of measuring data in the ACCESS®-data base format.

In case you want to develop your own software we offer a GMH3000-development package including

- an universally applicable 32bit Windows functions library ('GMH3000.DLL') with documentation that can be used by
all 'serious' programming languages.

- Programming examples for Visual Basic 6.0™, Delphi 1.0™, Testpoint™, Labview™

The Device has 2 Channels:

- Channel 1: Material-moisture in % and base-address

- Channel 2: Temperature

Note: The measuring and range values read via interface are always in the selected display unit (°C/°F)!

6.2 Analogue Output – Scaling with DAC.0 and DAC.1

With the DAC.0 and DAC.1 values the output can be rapidly scaled to Your efforts.
Keep in mind not to connect low-resistive loads to the output, otherwise the output value will be wrong and battery life is
decreased. Loads above ca 10kOhm are uncritical.
If the display exceeds the value set by DAC.1, then the device will apply 1V to the output
If the display falls below the value set by DAC.0, then the device will apply 0V to the output
In case of an error (Err.1, Err.2, no sensor, etc.) the device will apply slightly above 1V to the output.

8 Application in the glued timber construction acc. to

DIN 1052-1 (MPA certified)

The instrument with its curve h.460 (Fir) was certified by the MPA Stuttgart (Otto Graf institute) for applications in the
glued timber construction according to DIN 1052-1 with the following equipment:

- measuring cable GMK38

- reciprocating piston electrode GHE91 (recommended) or impact electrode GSE91

!

9 Inspection of the accuracy / Adjustment Services

Accuracy can be inspected with the testing adapter GPAD 38 (extra equipment).
To check precision select material characteristic curve “.rEF”, choose as moisture display „%u“ and connect the testing
adapter to the needles. The device must display the printed value for the GMH38xx

If the precision is no more corresponding to the imprint of the GPAD 38, we suggest to send the device to the
manufacturer for a new adjustment.
