- By Default every time a piezo controller is turned on , it check Strain Gauge Offset(by running the same test PZINFO does to determine if Strain Gauge offset is "OK" or "BAD"). If necessary it goes ahead and perform auto calibration routine. Changes in the sample weight, room temperature and aging require strain gauge calibration. + By Default every time a piezo controller is turned on, it checks the Strain Gauge Offset(by running the same test PZINFO does to determine if the Strain Gauge offset is "OK" or "BAD").
