REEL TORQUE ADJUSTMENT LOCATIONS
NOTE
Back Tension and Take-up Torque should be exactly within the specified
limits given on the next page (TORQUE MEASUREMENT PROCEDURES) .
VOLTAGE PRE-CHECK
It may be necessary to verify correct motor voltage before measuring
reel motor torque. Optimum voltage is approximately 2 volts (DC).
Procedure:
1. With Power "ON", confirm deck is in the ''STOP"' mode.
2. Connect a VOM or VIVM across the motor terminals (Points "A" and
"B') as shown. |
