The following appear only if inertia comp is used:
DIAMETER AT THIS WEIGHT
The roll diameter at the entered weight. Diameter must be
calibrated while the web is running. It is not necessary to calibrate
at the maximum velocity.
ROLL WEIGHT
The roll weight at any diameter in lbs or kgm.
RUNNING VELOCITY
The maximum running web velocity. Typical velocity can be used.
TIME TO ZERO SPEED
The time it takes the machine to stop when running at the above
velocity.
WIDTH AT THIS WEIGHT
This width is used to calculate density for the above roll weight.

EXCESSIVE ROLL
WEIGHT
(
Sensor(s) misapplied
The total weight of the sensor idler roll and
shaft must be less than
of sensor rating.
When two sensors are used this is the
combined rating of both (i.e. 100 lbs for two
50 lb sensors).
