7.4 Setting of the products
After entering the code (see chapter 7.3)
the product list is indicated on the
display in the same way as for the
product selection during the measure-
ment:
Select the product to be adjusted by
means of the arrow keys and confirm it
by pressing .
On the display the calibration factors
offset (constant factor, factory setting
»0.00«) and gain (proportional factor,
factory setting »1.000« are indicated.
The readings can be increased or
decreased by means of the arrow keys.
Notice:
The calibration of the instrument must
be prepared carefully. Pay attention to a
homogeneous sample material without
dirt and green grain portions. Do not
change the calibration after one
measurement only.
Carry out at least three measurements
with the HE lit e
average.
Calculate the average deviation to the
comparative instrument.
Example:
You obtained the values 15.7 %, 16.0 %
and 15.9 % with the same sample. The
average reading is 15.9 %.
The grain dealer measures 15.4 % with
his instrument, i. e. 0.5 % less.
This means that the reading of the HE lite
is 0.5 % would be too high.
In this case the parameter offset must be
set to »-0.5« so that also the HE lite
indicates an average reading of 15.4 %.
Control the modification by means of
your original sample.
Change to the next factor »GAIN« by
pressing .
