EXAMPLE:
If you are calibrating a 10,000 lb. load cell, you need a difference value
of at least 10,000 divisions. If you register a min value reading of 450
divisions with no load on the instrument and your min is 8450 divisions
at full load on the instrument, your difference value will be 8000
divisions. (8450 – 450 = 8000). To increase the gain press
(SET
GAIN) until you have more than 10,000 divisions.
Once the gain has been set, the zero point needs to be set. To set the
zero point, apply the 0% force to the instrument and press
(SET
MIN). Next apply the 100% force to the instrument and press
(SET
MAX).
To return to any prior screen you can always press
On the next page is an Instrumentation calibration chart listing max
divisions, as well as typical gain factors needed in calibrating each
instrument type.
