Calibration; Adjustment Of The Lcd Display Contrast - AgraTronix GMT-Grind Manual Del Operador

CALIBRATION

The GMT-Grind Grain Moisture Tester should be calibrated to match a
reference moisture tester.
a. Measure a sample with the reference moisture tester. For the purposes of
this example, it will be called Result A.
b. Measure the moisture with the GMT-Grind Grain Moisture Tester. For the
purposes of this example, it will be called Result B.
c. The offset value is Result A minus Result B, e.g. 17.3 - 16.6 = 0.7 %.
d. The offset value is changed by pressing and releasing both arrow keys
simultaneously. Now the offset value can be changed by using the arrow
keys.
e. Using the example, set the offset value at 0.7 %, and press the TEST
button to return to the previous mode. Press the TEST button again to test
the change.
This adjustment is stored for each grain.

ADJUSTMENT OF THE LCD DISPLAY CONTRAST

The LCD display contrast can be adjusted by pressing either of the arrow
keys until the display shows CONTRAST. Now press TEST and use the
arrow keys to adjust the contrast level up or down. When finished, press and
release the TEST button again.
CAUTION: Decreasing the LCD contrast too much may result in not being
able to see the characters, and increasing it too high may black out the
characters.
