2. Insert a Tension Meter into tape path and measure the back tension.
Fig. M2-1
3. If the reading is out of specification, make sure that there is no dust or
foreign material between the Brake Pad of Tension Control Arm Unit
and the S Reel Table.
After cleaning, the reading of tension measurement is still out of
specification, replace the Tension Arm Unit and the Tension Control
Arm Unit.
Fig. M2-2
Note:
1. Be sure that the three probes of the meter are all in solid contact with
the tape, but not touching any other parts of the mechanism.
2. It is recommended that measurements should be repeated at least
three (3) times because the tension meter is very sensitive to external
vibrations.
