Opti-Sciences, Inc. CCM-200 plus operator's manual
To Calibrate the unit, close the measuring chamber.
Important: make sure chamber is clear of any material.
Hold the chamber closed until the release arm message is displayed on the screen.
Calibration is not required in-between measurements, only when the system is powered up. The
unit is ready to take another measurement once the current measurement is displayed.
Test Types
There are three test types on a standard CCM-200 plus.
Single point measurement
This test saves every data point. Place the sample in the chamber, and press the head closed. A
value will appear when the test is complete. The next measurement may then be taken.
Multi-Point averaging
Multi-point averaging is used for some nitrogen management schemes. One can choose to
average from 2 to 30 measuring points Please refer to the following papers for more details.-
(Shapero 2006) (Francis 1999) The papers listed here, use 30 point averaging and 10 point
averaging respectively. Some crop consultants use fewer points to save time.
Multi-Point averaging with std. deviation flyer removal
This is the same test as listed above, but it will only allow averaging from 10 to 30 samples. If
the difference between measurements is greater than 2 sigma, the instrument automatically
throws out the measurement, and requires an additional measurement.
From the Test Menu and select setup.
Use the arrow keys to scroll through the various parameters available until the Test Type screen
is displayed.
