Battery
The meter is supplied with a 9-volt alkaline battery. This should be installed in the compartment on the
underside of the meter. When the battery is in need of replacement the message
Replace battery
will
appear on the display.
Only replace it with a similar high quality 9-volt alkaline battery. Removing the battery has no effect on the
information stored in the meter.
9-volt batteries should not be thrown away with trash. This may risk contact with other batteries or pieces
of metal which could lead to danger.
In case of battery leaking please remove carefully by using gloves. After removal please clean the device
carefully with a clean cloth.
Storage and Advice for General Usage
It is recommended that you store the meter at all times in the carrying case provided, so that the instrument
is not exposed to large temperature fluctuations and that it is kept free of moisture. If the instrument is
taken into a warmer environment from a cold storage location, it is recommended that you allow the unit to
acclimatise so that condensation does not affect the results of the measurement. At the end of the season,
wipe all surfaces with a well-wrung damp cloth and remove the battery from the meter. Clean all parts of
the grinder mechanism and lubricate the spindle with a thin layer of non-corrosive oil.
Auto Turn OFF time - Setting
Our Superpro is pre programmed to Turn-OFF after approximately 90 seconds of inactivity.
If the device turns off by itself while using it please turn on the meter by pressing ON/TEST.
How to make your own grain calibration
If you need to make a calibration scale for a particular crop that is not included in the meter, this can be
done as follows:
1. Turn on the meter by pressing ON/TEST.
2. When MEASURE appears press ON/TEST again.
3. Use the arrow keys
⇑
or
⇓
scroll through the crop options until Bit is displayed.
4. Fill the test cell with a sample of the desired crop for which you know the moisture content, grind
the sample and perform the test as described earlier.
5. Note down the value which appears in the display, eg. 03.65, and the temperature, eg. 19C, together
with the moisture content in the crop. Perform this process repeatedly using samples with different
levels of known moisture content until the calibration scale meets the range and requirements
needed. The more samples that are used the more accurate the calibration will be. Try always to use
samples at the same temperature.
6. Plot the values on a graph, either manually or using Excel, with moisture content on the y-axis and
Bit on the x-axis and draw a line or curve that best fits the points. The calibration is now completed
