Test
Problem: Changes in the Zero Balance.
Cause: Load Cell has been overloaded.
Remedy:
Step 1. Use a millivolt meter or the Integrated
Technician feature of the HI 2151/30WC
(See Physical Checks, Step 6) and measure
the LPS output under “no load” condi-
tions. The reading should be less than 1%
of the full scale output.
NOTE: Sensors can shift up to about 10% of their full scale
and still function correctly.
