CALIBRATION
The module assumes that a 2 millivolt full scale bridge transducer is properly connected to the
input (see connector wiring) with no load applied to the strain transducer. The zero adjustment
should have control and be able to position the bargraph anywhere along its scale.
1. Select appropriate range
2. Select appropriate measure units (i.e. lbs or kg.)
3. Select polarity (i.e. norm or rev.)
4. Set the display to zero on bargraph
5. Place a known calibrated mechanical load onto the transducer bridge and observe:
(A) Did the bargraph move in the proper direction? If not, reverse the norm/rev pin caps.
(B) Did the bargraph deflect to the proper calibration point? If not, adjust the mag control
to display the proper reading.
6. Repeat steps 4 and 5 several times to insure proper calibration has been set.
