Chapter 6 | Modifying The Moisture Indications Readings - DRAMINSKI HMM Manual De Uso

Modifying the moisture indications readings
This option is used for the modification (adjustment)
of moisture readings by increasing or decreasing the
displayed value (of the device) by the same value in
the entire measuring range. However, by modifying
the displayed values we are changing the measuring
range limits, i.e., when we make an adjustment
by „+2%" the measuring range will change from
10% – 80% to 12% – 82%.
The modification is made, if the user finds that
for a given force of the pressed bale the tool has
a tendency to over- or understate the results by
the similar value in the entire moisture range. This
modification is useful when the bales of hay/straw
are poorly or very hard pressed, because the HMM
curve is based on an average compression strength.
Procedure:
1. Press and hold four buttons at the same time:
"MAX", "MIN", "T/M" and "ON/OFF".

2. Hold 4 buttons pressed for about 1 second.
Then release the buttons – letters "CAL" will
be displayed.
3. Using "MAX" and "MIN" buttons set the number
399 and press "T/M".
4. When the display shows „0" the device is ready
for calibration.
5. Enter the requested adjustment, keeping the
range from – 5% to +5% (e.g. „+2" or „–5").
6. Confirm the entered value with „T/M" button,
then turn off the device.
An example of the correctly entered modification.
1. When you have entered „–5", then each time the
device is turned on, the display will show the
following message „CAL"–5. This means that the
device is changing the measuring range from
10% –80% to 5% – 75%.
