Introduction 3
Windy Conditions - Shocks - Vibrations:
The use of weigh modules is strongly recommended for all load cells to
compensate for misalignment of the support surfaces. The system designer must
ensure that the scale is protected against lateral shifting and tipping relating to
shocks and vibration, windy conditions, seismic conditions and stability of the
support structure.
Grounding The Weighed Structure:
By means of a 10ga solid or braided wire or braided grounding strap, connect the
load cell upper support plate with the lower support plate, then connect all the
lower plates to a single earth ground. Once installed electrostatic charges
accumulated are discharged to the ground without going through or damaging the
load cells. Failure to implement a proper grounding system might not affect the
operation of the weighing system; this, however, does not rule out the possibility
that the load cells and connected instrument may become damaged by ESD. It is
forbidden to ensure grounding system continuity by using metal parts contained
in the weighed structure.(see Figure 1-1.)

1. From the weight display, press for 3 seconds.
2. The display will read NU-CEL. Press .
3. The response signal of the load cell is displayed, expressed in mV with
four decimals. Press three times to exit set-up mode.
