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 EC
TRIME
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:
