Calibration
The REF-METER-OCTA is calibrated at the factory to provide high accuracy. While
recalibration should seldom, if ever, be necessary, recalibration is performed easily without
sending the product to the manufacturer for service. A known calibration weight (in
kilograms) is required to recalibrate the scale, and can be any value between 5 kg and 100
kg. 25 kg is recommend. Best accuracy is obtained by using the largest weight available (i.e.
a 50 kg calibration weight will provide better calibration accuracy than a 5 kg calibration
weight). In addition, it is necessary to know the weight to within 2 grams.
To recalibrate the REF-METER-OCTA, perform the following steps:
1. Place the REF-METER-OCTA weighing platform on a firm, level surface.
2. Turn the power to the REF-METER-OCTA off.
3. Remove all objects from the platform.
4. While holding
after a few seconds the display will show SET CAL and 25.000 kg.
5. Using or

6. Press . A number representing the weight of the unloaded platform will appear on
the display. Press
7. Apply the calibration weight to the platform. A number representing the applied
reference weight will appear on the display. Allow at least 10 seconds for this number to
stabilize.
8. Press . The REF-METER-OCTA is now recalibrated to the reference weight.
9. Refer to the Quick Start section above for setting the desired Units and Resolution.
