IMPORTANT: Keep the box and all packing material. Any unit returned to Agtron for service must be shipped in the original packaging or Agtron will not accept the unit. The carton contains the following items: - E20CP-III Analyzer - Power Cord - Large Diameter Yellow Life Disk - Two Plastic Sample Dishes - Smaller Diameter Two-Sided Red / Black Calibration Disk &... - Page 5 NOTE: The power switch for the E20CP-III is on the back panel next to the power-cord connector. Always leave the unit on for best accuracy and stability; it uses very little power, about as much power as a 15-watt light bulb.

Page 11: Testing Coffee Samples
V. TESTING COFFEE SAMPLES Sample Preparation The E20CP-III is designed to evaluate both whole bean and ground samples. A sample can first be analyzed as whole bean and then as ground. The difference between the two scores approximates how uniformly or non- uniformly the sample is roasted. -
Page 12: Selecting The Analytical Scale
The Gourmet Scale offers higher resolution (shows a greater difference in scores between two roast classifications) Custom Scale allows the user to modify the E20CP-III Commercial Scale scores with the following equation: QMS = A x (S x S) + (B x S) +/- C (See Section VII. -
Page 13: Accessing & Editing The Custom Scale Variables
The Custom Scale will only be active if it is selected in Section VI. Custom Scale Score represents the E20CP-III Commercial Scale score as modified by the equation: (Custom Scale Score) QMS = A x (S x S) + (B x S) +/- (C) - Page 14 Key-in the desired A value and depress the [ENTER] key to save and move to the B variable << CUSTOM – SCALE >> The display first shows: QMS = A x (S x S) + B x (S) + C Followed by the top line of the display showing: QMS = A x (S x S) + (B x S) + C alternating with...

Time from Roasting / Cooling / Grinding to Analysis Once coffee is roasted it begins to decompose. Since the E20CP-III is a system based on chemistry analysis, it will see the change of decomposition much in the same way you taste it in the cup. A sample’s score can change (lower) as much as 4 points in 24 hours. -
