Special sensor grounding considerations
The DI-1000 has two ground pins, EARTH ground, and SIGNAL ground. Connection to both pins
should be carefully considered for each application. The very high accuracy possible using the DI-
1000 can easily be compromised with an incorrect connection to EITHER of these two pins!
Firstly, make sure you know how your load cell is wired! If your load cell has 4 wires and one
shield, that shield may be attached to the body of the load cell. Verify this with an ohm-meter or
continuity test! If your load cell has 6 wires, and two shield wires, one is the sensor body, the other
is the signal shield.
