Measurement
The HD2 handheld device has three operating modes:
1. Single value single value display - displays the measured variables "moisture", "temperature"
and "EC-Trime"
2. Average displays the average moisture value calculated from up to 6 individual measure-
ments
3. Water calculation calculates the water content in l/m³
Note: No additional actions are possible during a measurement. The user must wait until
the measurement is finished.
6.3.1 "Single values" operating mode
The "Single values" operating mode is the ideal mode for determining all the soil parameters that can
be measured with a TRIME probe. The unit displays the moisture as a "%", the soil temperature in "°C"
or "°F" and the measured conductivity ECTRIME in "dS/m".
Once the HD2 handheld device is switched on, the following screen is displayed after the initial
start-up screen:
To start measuring, press the "Measure" key briefly. The device starts measuring and a rotating
symbol appears in place of the battery in the top right-hand corner for the duration of the meas-
urement process. No other actions can be performed during this time. The measurement takes around
4-5 seconds. Once the measurement is finished, the battery symbol appears on the display again along
with the measured values. The values continue to be displayed on the screen until a new measurement
is carried out.
6.3.2 "Average" operating mode
In this mode, only the moisture is determined and an arithmetic average is calculated from up to six
individual values. The volumetric or the gravimetric moisture is displayed depending on the set
calibration. This operating mode is suitable for measuring the moisture values of large volumes of
material (e.g. sand, gravel etc.).
Once the HD2 handheld device is switched on, the following screen is displayed in the "Average"
operating mode after the initial start-up screen:

6.4.1 HD2 mode
The operating mode of the HD2 handheld device can be changed in this menu item.
With the "Single value" option, the user selects an individual measurement of the three probe
parameters: moisture, temperature and EC-Trime.
Depending on the selected calibration, the "moisture" parameter displays the moisture as a volumetric
or gravimetric percent or can output the transit time of the TDR pulse. If the transit time is displayed,
the percentage sign is understood as "Raw value tp".
If the "Average" option is selected, only the moisture is determined - in %vol or %grav depending on
the calibration selected - or the transit time in tp. The measured value is saved in a list of up to six
measured values. The arithmetic average is calculated from this list.
Note: Only a maximum of 6 values can be saved in the list. Older values are removed from
the list and are no longer used to calculate the average.
The "Water calculation" setting activates a mode that indicates the water quantity in the material
being measured in l/m³. To be able to measure larger volumes of material, a material sample can be
taken at several points and an average calculated.

Press the "Up" and "Down" keys to highlight the desired entry and press the "Measure" key
to select it. Once the entry has been selected, the symbol appears in the top right-hand corner of
the display indicating that the option has been activated and saved.
6.4.2 Material calibration
Different calibrations are saved in the probe depending on the intended application of the probe. This
can be volumetric calibrations for soils of different densities, gravimetric calibrations for sand mois-
ture measurements or also transit time calibrations.
You can select the calibration needed for your application in the "Material calibration" menu item. This
makes it possible to use the same probe for different applications. In addition, you also have the option
of programming and performing your own calibrations here in order to be able to measure special
materials.
Once you have selected the "Material cal." menu item, choose
either "SELECT" to set one of the 15 calibrations or
"CUSTOMIZE" to program a new calibration to one of the
15 calibrations saved in the memory.
Menu item: "SELECT":
The 15 calibrations, and the names of the calibrations, appear on the display. This may take a
moment. Then a screen similar to that shown below appears:
Press the "Up" and "Down" keys to scroll through the
list and select the desired calibrations. The "!" symbol in front
of a calibration indicates the currently active calibration.
Press the "Measure" key to set the selected calibration as
the active calibration. After a brief moment, the symbol
appears in the top right-hand corner of the display, indicat-
ing that the option has been activated. In addition, the "!"
symbol appears in front of the active calibration.
TIP: You can also access this menu item directly from the measurement window by pressing the
"Up" key .

MMP20 SONO Mobil HD2 (option E)
Page 18 Endress+Hauser
Menu item: "CUSTOMIZE":
Here, you have the option of performing your own material calibrations or of customizing existing
calibrations to suit your particular needs. Two options are available for this:
1-point calibration:
- Adjusts the calibration curve to the selected point.
- The slope is not changed.
- Just one material sample is required.
2-point calibration:
- Creation of a linear calibration between two measured
points
- Two material samples with different moisture values are
required
1-point calibration:
This material calibration option merely adjusts (offsets) the configured calibration. As the slope is not
changed, it is important at the start to select a calibration curve that suits the material.
NOTE: You require a sample of the material being measured to perform a 1-point material
calibration. The moisture value must be determined with another method (weighing and
drying, or similar) before the calibration.
Procedure:
At the start of the calibration, the calibration memory
(01 –15) to be overwritten must be selected with the
"Up" and "Down" keys. Press the "Measure" key to
accept the setting.
Then set the percentage moisture using the "Up" and
"Down" keys, and again press the "Measure" key to
confirm your entries.

MMP20 SONO Mobil HD2 (option E)
Endress+Hauser Page 19
To start measuring the material, press the "Measure" key
again. Four measurements are taken to increase the accu-
racy. An average of these measurement values is then cal-
culated. The measuring time is approximately 20 seconds.
When the measurement is finished, the measured pulse
transit time is displayed briefly.
NOTE: Before you start measuring, make sure that the
rods of the probe are fully immersed in the mate-
rial to be measured. The probe must remain in the
material for the entire duration of the measure-
ment and should not be moved.
CAUTION: If you select "SAVE" at the end of the calibration, you overwrite one of the pre-configured
calibrations (or one you may have already modified) in the probe! The original
calibrations can only be restored with a PC and the Pico-Config software, as well as an
RS485 adapter (e.g. SM-USB).
After this, the calibration can be saved to the calibration
memory set at the start ("Save"). The selected memory is
only overwritten once the "Measure" key is pressed. The
word "OWN:" now appears in front of the original memory
name to clearly indicate which memory has been overwrit-
ten.

MMP20 SONO Mobil HD2 (option E)
Page 20 Endress+Hauser
2-point calibration:
In a 2-point calibration, two material samples of different moisture content are measured and a linear
equation (f(x)=mx+b) is then calculated from this information. While a higher-value polynomial is
useful to achieve better accuracy, the linear equation often suffices, particularly in the lower moisture
range, and delivers very good results.
NOTE: You require two material samples with different moisture values to perform a 2-point ma-
terial calibration. The moisture values must be determined with another method (weigh-
ing and drying, or similar) before the calibration. Make sure to adhere to the following
sequence: first "lower moisture value" (drier material) and then "upper moisture value"
(wetter material).
Procedure:
At the start of the calibration, the calibration memory
(01 –15) to be overwritten must be selected with the
"Up" and "Down" keys. Press the "Measure" key to
accept the setting.
Then set the percentage moisture of the lower moisture
value using the "Up" and "Down" keys, and again press
the "Measure" key to confirm your entries.
To start measuring the material, press the "Measure" key
again. Four measurements are taken to increase the accu-
racy. An average of these measurement values is then cal-
culated. The measuring time is approximately 20 seconds.
When the measurement is finished, the measured pulse
transit time is displayed briefly.
NOTE: Before you start measuring, make sure that the
rods of the probes are fully immersed in the ma-
terial to be measured. The probe must remain in
the material for the entire duration of the meas-
urement and should not be moved.
Then set the percentage moisture of the upper moisture
value using the "Up" and "Down" keys, and again press
the "Measure" key to confirm your entries.
