All signal
levels fall
within the +0

range
The Millivolt range is
outside the
+0 to +15 mV range
Check for

Millivolt reading is
slow or 0.0 mV. It
may be a negative
reading. Use a multi-
meter to confirm
Replace the load
cell if the unit signal

SMART DIAGNOSTICS is a built-in system diagnostics
utility that enables the operator to rapidly
troubleshoot a weighing system from the front panel,
PDA or Web Browser of the HI 3030. Used with an HI
SD card you can read each individual load cell in mV,
mV/V and weight to determine if a load sensor is
malfunctioning or not connected.
Apply weight
