1 General Notices

Please read the operating instructions carefully.
Should you have any further questions, please contact our service department under the contact data de-

picted above. In no event should you attempt to open and repair the device yourself. Should you like to file
any guarantee claims, please contact the distribution partner where you purchased the device.

Within the scope of product improvements, the device is subject to technical and optical changes.

1.1 Intended Use

This handheld device was designed to serve as a reading device for various IMKO probes. Only respectively
intended probes may be connected to the device. The connection of a probe not intended for connection
may lead to the destruction of the device and/or the connected probe.

1.2 The Chargeable Accumulator

Never exchange the integrated accumulator yourself.
The stated maximum operating periods refer to ideal conditions. The ambient temperature and the charging

cycle can significantly reduce the performance time. In addition, the charging capacity reduces itself for
technical reasons within the course of the utilization of the device or due to storage at very high or low tem­peratures.

1.3 Charging the HD2 Handheld device

Only deploy the respectively provided charger or a comparable power supply unit to charge the HD2
handheld device. Any deviation of the charging voltage can lead to damage to the device.

Should the device heat up during the charging process, this is normal and not connected with any hazards.
Should the HD2 only function for a short period or not at all in spite of several attempts to charge it, the inte-

grated accumulator is defective and must be exchanged. In this case, please contact our local distribution
partner or us directly.

1.4 Temperatures and Ambient Conditions

The HD2 handheld device was designed for deployment under rough conditions.
The operation of the device under conditions beyond those depicted may lead to damage to the same.

3 Initial Commissioning

3.1 Safety Instructions

Attention: Before initial commissioning, do not fail to read the General Notices, Item 1 at the front of these

operating instructions. Any not intended use may lead to damage to the device.

3.3 Charging the Accumulator

The integrated accumulator should be charged before putting the device into operation the first time. For this
purpose, plug in the provided charging adapter into the 7-pole socket of the HD2. Subsequently, connect the
plug-in power supply unit to the charging adapter. In the event that the device is already switched on, or if
the accumulator is exhaustively discharged, the charging process will commence immediately. If not, switch

on the HD2 by pressing the button „Measurement“ for approximately 1 second. An active charging pro-
cess is signalised in the display by an animated accumulator symbol.

The integrated charging electronics charges the accumulator until the same is completely charged. In case
of exhaustive discharge, this will approximately take 2 hours. As soon as the charging process is concluded,
all 4 „accumulator bars“ will be permanently presented in the display and the trickle charging will commence.

Attention: Only charge the accumulator at room temperature (approximately between 10°C and

30°C)! At too low temperatures, it may happen that the charging concluding shut­down does not operate safely and the accumulator is over-charged. Too high ambient
temperatures may lead to damage to the HD2 due to the additional heat-up during the
charging process.

3.4 Connecting a Sensor

The HD2 handheld device can be operated with the following IMKO-moisture probes:

Connect the moisture probe to the HD2 by plugging in the 7-pole plug into the respectively provided socket
at the HD“ and fastening the coupling nut.

4.1 Switching ON the HD2 Handheld device

Switch ON the HD2 by pressing the button „Measurement“ for approximately 1 second.

During the starting-up process, the HD2 will attempt to communicate with the connected probe. This will take
approximately 4 seconds. If no probe is connected, or the probe is not able to communicate for any reason,
an error message will be generated on the display.

If the probe was successfully detected, the accordingly set background of the operation mode will appear on
the display and the HD” is ready for deployment.

Notice: Should no connection to the probe be possible in spite of several attempts, check if the

probe is connected properly. Should this not deliver a positive result, please contact our ser­vice department.

4.2 Switching OFF the HD2 Handheld device

Switch OFF the HD2 by pressing the button „Measurement“ for approximately 1 second.
Notice: It is not possible to shut off the HD2 while it is in the „Settings“. Please, first leave the menu

item „Settings“ by pressing the button „Settings“ until the measurement display appears.

4.3 Measurement

The HD2 handheld device disposes of three operating modes:

1. Normal  Individual Value Display – presents the measurement variables Moisture, Temperature
and the EC-TRIME

2. Average Value  presents the average value of the moisture of up to 6 individual measurements

3. Water calculation  determine the content of water in l/m³

Notice: During a measurement, no further actions are possible. It is necessary to wait until the

measurement is concluded.

4.3.1 Operating Mode „Normal“

After switching on the HD2 handheld device, the following display will appear in the operating mode „Normal“
after the start screen:

In order to initiate a measurement, shortly press the button “Measurement” . The measurement will com-

mence and a turning -symbol will appear instead of the accumulator-symbol in the upper right hand cor­ner. During this period, no other actions can be performed. The measurement requires approximately 4 to 5
seconds. Once the measurement is concluded, the accumulator-symbol will reappear and the measured
values will be generated on the display. The display of the values will be maintained until a new measure­ment is conducted.

4.3.2 Operating Mode „Average Value“

In this operating mode, only the moisture is measured and an average value of up to 6 individual values is
evaluated. Depending on the set calibration, either the volumetric or the gravimetric moisture is presented.

After switching on the HD2 handheld device, the following display will appear in the operating mode „Aver-

age value“ after the start screen:

In order to initiate a measurement, shortly press the button “Measurement” . The measurement will com-

mence and a turning -symbol will appear instead of the accumulator-symbol in the upper right hand cor­ner. During this period, no other actions can be performed. The measurement requires approximately 4 to 5
seconds. Once the measurement is concluded, the accumulator-symbol will reappear. On the left hand side
of the display, the individual values of the measurements will be presented. The currently measured value is
presented at Position 1 and old values will be shifted one position onwards. The arithmetic average value is
displayed on the right hand side. The average value is calculated out of the existing individual values up to a
number of 6 values.

Notice: Only a maximum of 6 values can be stored in the list. Older values are removed from the list

and are no longer involved in the formation of the average value.

In order to delete the measurement series, actuate the button „Down“ .

4.3.3 Operating Mode „Water Calculation“

In this operating mode, only the variable Moisture is measured. There will be up to six single values stored
and concluded to an average value. Out of this the water content per m³ is calculated. To get the correct
water contend it is necessary to set up the density of the measured material.

The continuous measurement is initiated by actuating the button „Measurement“ . The same is concluded
by actuating the button „Measurement“ once more. The currently pending measurement is performed

completely once more and the sequence is concluded.

In order to delete the measurement series, actuate the button „Down“ .

To set up the density of your material, actuate the button „Up“ . Then you will get the following screen in
the display:

Adjust the density of your material by actuating the buttons „Up“

and „Down“ . Confirm your setting by pressing the button

“Measurement” . You will then automatic get back to the meas­urement screen. Leave the setting without changing the density by

pressing the button „Settings“ .
