Chapter 4: Calibration
The calibration mode is accessible through the configuration menu or from the weigh mode.
ACCESS CALIBRATION FROM APW LOOKUP MODE
1. From the main menu press the 7 (Setup) key.
2. Press
6 (Setup Menus) key.
3. Press
3 (CAL) key.
4. Enter the access code and press
ACCESS CALIBRATION FROM THE BASIC WEIGH MODE
1. Key in ?JJ >
2. Enter access code
DC@B?
3. Select a calibration method from the list below.
CALIBRATION METHODS
There are six methods of calibration. Press > to select a calibration method. Press to begin the
calibration method selected. Refer to the appropriate section for calibration instructions.
• New Zero - Establishes a new zero (no load) and span (test load) calibration reference.
• Last Zero - Performs a span re-calibration without removing the test load. (This selection is not
available with linearization enabled.)
• Temp Zero - Performs a calibration without removing the current gross weight. The zero
reference determined during the last calibration is maintained. (This selection is not available with
linearization enabled.)
• Only Zero - Establishes a new zero reference without affecting span.
• Cal Reset - Adjusts the zero and gain factors of the A/D amplifier to default values for maximum
sensitivity.
• Known LCOut - Calibrates without the use of test weights. The mV/V value and full scale
capacity of each load cell must be known.
GENERAL NOTES ON CALIBRATION
• Pressing K at any point in the calibration routine moves back one step.
• Pressing
K at the New Zero? prompt exits calibration mode.
