CALIBRATION
When to calibrate
• When the scale is initially installed
• When the scale’s location has changed
• After the scale has not been used for a long period of time
• If ambient temperatures have changed greatly
How to Calibrate (Span)
• Press the power button to turn the scale on
• When there is no weight on the pan hold the CAL key for about 5 seconds
• When display shows “-CAL-”, release the CAL key
• The display will flash the exact weight needed to calibrate
• Place exactly the required weight on the scale
• When the display stops flashing unload calibration weight
• “---” will be displayed briefly to indicate the completion of span calibration
• The display should show 0
• Place your calibration weight on the scale. If the scale reads the same value
the calibration has succeeded. If not please repeat calibration
process.
How to Linear Calibrate
• Linear calibration
• Verify the pan is empty
• Press the CAL (calibration) key for about 5 seconds to enter into calibration
mode. When display shows “-CAL-”, release the CAL key
• Press and hold the MODE key for about 5 seconds, and the blinking number
indicates what weight should be placed on the pan
• Load the indicated weight, and wait for the display to stop blinking (scale has
recorded this linear value)
• Unload the weight
• Wait for the next blinking number to indicate what weight to place on the pan
• Load the indicated weight, and wait for the display to stop blinking (scale has
recorded this linear value)
• Unload the weight
• When the display shows “0.000”, it means the linear calibration is completed
