CALIBRATION
Calibration
This scale has been factory calibrated, and does not require calibration prior to use. There are no
requirements for calibration in the field; users should adhere to their institution's calibration policies. If required,
the scale can be calibrated. Calibration of your scale is performed using 80 kilograms (KG) or 200 pounds
(LB), according to the units of measure used upon entering into the calibration path. Note: If Everlock
engaged the scale can only be calibrated in the locked unit of measure.
Note: Only weights certified and traceable to national standards should be used for calibration
procedures.
1. Press and hold the UNIT and ZERO buttons at the same time, and press and release the
turn on the scale. Remain pressing the UNIT and ZERO buttons until "CAL" appears on the display.
Release all buttons. Note: The display will show "CAL" until the button combination is released.
2. Once the buttons are released the following message will scroll horizontally across the screen : "–
2Ero SCALE – ". With no weight on the platform, press the ZERO button.
3. The scale will zero and the following message will scroll horizontally across the screen: "- PLACE 200
ON SCALE PrESS EnTEr–" (if in pounds) or "– PLACE 80 ON SCALE PrESS EnTEr– " (if in KG).
You may toggle between pounds and kilograms using the UNIT button. If Everlock
only be able to calibrate in the locked weight measurement unit.

the weight from the scale and the scale will restart. Note: the 4 digit calibration count will stay
until the weight is removed.
B. If the weight placed on the scale does not match the correct calibration standard (200 lb or
80 kg), the following message will be displayed: "– Out OF RANGE –". Calibration is not
performed. Press CLEAR button to exit the calibration mode. The scale will restart and go
through the power up sequence to show 0.0. Power off the scale and begin the calibration
