Section 5. Scale Calibration

Entering and Exiting Setup Mode

To enter setup mode from the front panel
1. Press ZERO to turn the scale on.
2. Press and hold ZERO and UNITS simultaneously for 5 seconds until the
display reads Prset.
3. Press REWEIGH 3 times and the display will read CAL n.
If calibration needs to be aborted when in process, press REWEIGH to exit and
not save changes. Once calibration is completed, the scale will automatically
display SAVED return to normal weighing operation to verify calibration.
Two calibration procedures are offered.
• The Two Point calibration will calibrate the scale using only one weight
that can be user defined. This calibration procedure is effective and can
be used in the field with a test weight, or by using your own body weight.
• The Multiple Point calibration procedure requires four separate test
weights. This procedure offers the greatest accuracy and is intended for
factory or field calibration by a scale technician.

Two Point Calibration Procedure

1. When the setup mode is entered the display reads CAL n.
2. Press the ▲ button to change the display to CAL y.
3. Press BMI.
4. The display will now show CAL 0. If necessary, press UNITS to calibrate in
kilograms.
5. Remove all weight from the scale platform.
NOTE: During calibration be sure vibration and air currents are not present.
Calibrated test weights result in the most accurate scaling.
6. Press BMI to perform a zero point calibration. The display will count down to
zero. The counter will reset if too much motion (Er nn) is detected.
7. The scale will display 500.0 (226.8 kg). Representing a 500 lb (226.8kg) span
point calibration.
8. If desired, change the calibration weight by using the up or down arrow button
to scroll the weight value.
NOTE: If not calibrating with full capacity, the recommended minimum span
weight is 200 lb (100 kg).
9. After the span weight has been entered, place the calibration weight on the
platform.
10. Press BMI to accept the span weight value. The display will count down to zero.
11. The display reads SAVED and exits to the weigh mode. Verify calibration
accuracy with your test weights.
