Checking The Load Cell
Follow these steps:
1.
Check the Wheatstone bridge
a.
Set your multimeter to ohms (Ω). If your meter does not auto scale, set it to the
just high enough to read 350 Ω. This will likely be the 2k or 2000 setting.
b.
Referring to the picture above, place one of the probes on terminal 1 (red wire).
c.
Place the second probe on terminal 2, 4, and 5 recording the resistance at each
terminal. The resistances should match the table below.
2.
Check Static Output
a.
Set your multimeter to the millivolt (mV) setting.
b.
Check and record the voltage between terminals 1 and 5. A good load cell will
read very close to 00.0mV at rest with no vehicle loaded.
3.
Check Dynamic Output
a.
Set your multimeter to millivolt (mV) as with the last test.
b.
Place the multimeter pins on terminals 1 and 5 again.
c.
Have another person rock the drum back and forth a couple inches (careful not to
pinch fingers) each way while you watch the multimeter display.
d.
Record the high and low numbers seen while rocking the drum.
e.
Depending on the force applied in rocking, the readout should be ~±.3mV.
