6. Tension checks
Back Tension Measurement /Adjustment
1. Confirm that the position of the tension pole is correctly positioned. If not, refer to the "Tension Pole Position Adjustment
Procedures"
2. Play back a T-120 tape from the beginning for about 20 seconds (wait until tape transporting system comes to be sta-
ble).
3. Insert the Tensiometer on the tape path (fig. 6) and measure the back tension. the measured result must meet the spec-
ification (25-33gr).
4. If the result is not within the specification, adjust the tension spring (If the measured result exceeds the specification,
locate the spring on the hook "A". If the value does not reach the specification, locate the spring on the hook "B".) and
repeat the step 1 thru 3 of "Tension Pole Position Adjustment" (fig. 7).
NOTE :
• Make sure that all of the three probes of the Tensiometer are on contact with the tape, but not with any other parts of the
Deck mechanism.
• It is recommended that the measurement should repeated at least three times to guarantee an accurate reading.
