CAUTION:
IN THE NEXT STEP, DO NOT OVERLOAD THE SCALE BEYOND FULL
CAPACITY RATING.
– Measure the voltages on +SIG and –SIG wires, disconnected from PCB.
Note:
Measurements must be made with these wires disconnected from the
PCB. These measurements represent the output of the Load Cell. Record
measurements at Zero Load, 50% and full scale capacities. See Table 2-3 for
typical readings.
Figure 2-1. Top view of main PCB.
NOTE
: Table 2-3 indicates typical readings. Actual values can vary, but should
remain linear throughout the range. If readings are out of tolerance, replace the
Load cell. (See Section 3.6.)
