5 Principles of the measurements
5.1 Moisture rating ( WET - MEDIUM - DRY )
In addition to the measuring value there is a moisture rating via bar graph:
Therefore the determination ‘wet’ or ‘dry’ is easy and comfortable for most applications and has no
longer be deduced from literature and tables.
However, this rating can only be a first approximate value, because factors like the ap-
plication field of the measured material have to be taken into account for the final rating.
Experience and knowledge can only be supported by this instrument, not replaced!
5.2 Moisture
u
and water content
w
Either moisture u or water content w is needed according to the application. The BaleCheck 100 is
supposed to be used the unit moisture u (relating to oven-dry mass). In some cases, like rating of
combustibles, the water content w may be more suitable.
The instrument can be configured to both of the values, please refer to chapter 6.
Moisture u (relating to oven-dry mass)
– recommended setting
The unit is %u (also common: % atro, weight percent)
mass
wet
:
mass of the sample (= total mass = mass
water
+ mass
dry
)
mass
water
: mass of the water contained in the sample
mass
dry
:
mass of the oven-dried sample after (water has been evaporated)
Example: 1 kg wet hay that contains 500 g water has a moisture u of 100%
Water content w (= moisture relating to wet total mass)
The unit is % w.
Example: 1 kg wet hay that contains 500 g water has a water content of 50%
5.3 Temperature compensation
The temperature compensation is important for a reliable moisture-measuring.
There for the device features a manual temperature compensation input.
According to the selected material characteristic curve the device will use the associated tempera-
ture compensation.
Temperature selection:
• press shortly
: in the left display will appear:
t.°C
or
t.°F
• set the temperature by pressing
or
.
• press
again to switch back to the measuring display.
5.4 Auto-Hold function
Particularly when measuring dry materials, electrostatic charges and other similar noise could dither
the measuring value. With activated auto-hold function the device will acquire an exact measuring
value automatically. During that, the device could be put down to avoid noise through discharge of
the clothing etc.
After having acquired the measuring value, the display will change to ‘HLD’: The value will be fro-
zen as long as a new measuring is initiated by pressing key 3 (hold).
m
oisture u[%] = ( (mass

) *100
or:
m
oisture u[%] = (mass

) *100
water content [%] = ( (mass

) / mass

) *100
or:
water content [%] = (masse
water
