SETUP AND CALIBRATION
Your Model 750 indicator has been thoroughly tested and calibrated before being shipped to
you. If you received the indicator with a scale, calibration is not necessary. If the indicator is
being connected to a scale for the first time or recalibration is necessary for other reasons,
proceed as indicated.
Calibration of the indicator is accomplished entirely by the keypad. To enter setup and
calibration, the calibration switch must be pushed in and held while turning on the indicator.
Begin Setup and Calibration:
1. With power off, remove the 2 screws from the left
end cap (as viewed from indicator front) and

key to view the current setting. To retain the current
setting and proceed to the next prompt, press the

the a or b keys (up or down arrow) to scroll through
and select a new value. After a new value has been
selected, press the BMI/ENTER key to save it and

prompts have values with 2 or more digits. The
blinking character is the position to be changed and
can be advanced to the next position by pressing the
