5-6-2. Span calibration
Span calibration adjusts the instrument’s span (gain) parameters by placing a known
weight on the load cell.
Enter the known weight value to BALANCE WEIGHT field. To obtain a good
linearity, use of a weight heavier than 50% Capacity is recommended.
Before performing calibration, make sure unwanted load is applied to the load cell (See
“Zero calibration”).
Make sure that indicator is off and reading is stabilized. Good calibration
cannot be obtained while readings are fluctuating.
* While the instrument is running, indicator becomes reversed display (light
blue). The user must either stop the instrument or enter a password (see page 32 for the
password).
