1 General Notices

Please read the operating instructions carefully.

Should you have any further questions, please contact our service department under the contact data

at the end of this document. 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 the

listed probes may be connected to the device. The connection of a probe not intended for connection

may lead to damage of the device and/or the connected probe.

1.2 The Chargeable Accumulator

Never change 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 is

decreasing 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 use 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 of the device.

The device is heating up during the charging process.

Should the HD2 only function for a short period or not at all in spite of several attempts to charge it, the

integrated 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 of the device.

3 Initial Commissioning

3.1 Safety Instructions

Attention:

Before initial commissioning, please read the General Notices in the first chapter of this operating

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

3.2 Checking the scope of delivery

•HD2 Handheld device

•Plug-in Power Supply Unit (12V/2A)

•Charging Adapter

•Protective Hood

•Manual

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 completely 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 process is indicated in the display by an animated accumulator symbol.

The integrated charging electronics charges the accumulator until it is completely charged. In case of

complete discharge, this will approximately take 2 hours. As soon as the charging process is completed,

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 accumulator is over-charged. Too high ambient temperatures may

lead to damage of 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 socket at the HD2 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 operation mode will appear on the display and the HD2 is

ready for use.

NOTE:

Should no connection to the probe be possible after 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.

NOTE:

It is not possible to shut off the HD2 while it is in the „Settings“. Please, first leave the menu

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

4.3 Settings

There are various options to modify and align the settings of the HD2 handheld device. You will reach

the following menu configuration by pressing the button „Settings“ :

By actuating the buttons „Up“ and „Down“ , the entry intended for processing can be marked and

subsequently be selected with the button “Measurement” . You can exit the current menu item and

also the menu “Settings”, with the button “Settings” .

4.3.1 HD2-Mode

In this menu item, the operating mode of the HD2 handheld device can be changed.

With the selection „Normal“, an individual measurement of the three probe parameters Moisture,

Temperature and the EC-TRIME is selected.

The parameter Moisture is, depending on the selected calibration, showing the moisture in volumetric

or gravimetric percentage or showing the running period of the TDR pulse. When showing the running

period of the TDR pulse, the unit is „ns“.

When selecting “Average Value”, depending on the selected calibration, only the moisture in %vol or

%grav, respectively the running period in “ns”, is determined. The measured value is stored in a list of

up to 6 measurement values. The arithmetic average is determined from the shown values.

NOTE:

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

are not used for the calculation of the average value.

The selection “Water Calculation” will switch on the mode determining the content of water in l/m³ of the

measured material. To get the moisture of a bigger volume, it is recommended to probe at various places

of the material. The single values will calculated up in one average value.

By actuating the buttons „Up“ and „Down“ , the entry intended for processing can be marked and

subsequently be selected with the button “Measurement” . After the selection, the symbol will

appear in the upper right hand display corner which indicates that the selection is activated and has

been stored.

The HD2 handheld device offers 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 →determines and presents the content of water in l/m³

NOTE:

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

ement is concluded.

4.3.1.1 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

commence 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 displayed results will remain until a new measurement is started.
