1. Zero Adjust
The zero output (4mA) can be adjusted by holding a magnet close to the
can, approx. 1 1/2 inches from the top or bottom of the can.
If the zero output values do not change right away, hold the magnet in place
near the top of the can until the values change, up to two minutes. If there is no
change, repeat the procedure near the bottom of the can. If there is still no
change,consult the factory.
Holding the magnet Holding the magnet
perpendicular near the perpindicular near the
top increases the output. bottom decreases the
output
Note: Span calibration must be done at the factory.
2. Suspension Mounting
