1. Features
The Model AN-900 compostion analyzer is a compact-size grain
tester (Transmittance type) that utilizes applied near-infrared rice
analysis technology.
It employs total-grain measurement formulas for measuring with-
out crushing the sample grain to pieces, so it makes it possible to
analyze grain quickly and easily.
By ultilizing halogen lamp, grating system and NMOS photo-di-
ode array detector, and the result is that we are able to achieve
high stability.

5-2. Calibration Selection
With near-infrared composition analyzers similar to this unit, you prepare each pre-
calibration and then analysis compositions. AN-900 has an eight channel capacities
and pre-calibrations is done by our company. Before starting analysis, please select a
proper calibration according to the grain you want to measure.
Operation Display Explanation
1. By using keys, select
the “Calibration” setting.
2. Press the key.
The list of pre-calibration is dis-
played.
3. Select a calibration by using
keys.
4. Press the key.
Calibration will be selected and
back to initinal screen.
The existing, selected Calibration is
diplayed.
Note :A backup battery has been built to this unit so that even if the electricity is cut-off, the calibra-
tion in memory will not be lost. Please contact the service desk of our company regarding an
replace of backup battery.
