Purpose of Measuring : To measure and check the reel torque on the take-up part and the
supply part that performs basic operation of the VCR (VCP) for
smoothly forwarding the tape.
Measure and check followings when the tape is not smoothly
wound or the tape velocity is abnormally proceeded:
4-14
• Torque Gauge
(600 g.cm ATG)
• Torque Gauge Adaptor
• Cassette Torque Meter
SRK-VHT-303
• Play (FF) or Review
(REW) Mode
• Try to operate the VCR (VCP) per mode with the
tape not inserted (See ‘2. Prior Preparation for
Deck Adjustment).
• Measure after adhering and fixing the torque
gauge adaptor to the torque gauge (Fig. C-3-1)
• Read scale of the supply or take-up part of the
cassette torque meter (Fig. C-3-2).
DECK MECHANISM ADJUSTMENT
1) Take the power cord from the consent.
2) Separate the top cover and the plate assembly top.
3) Insert the power cord into again.
4) Turn the VCR (VCP) on and load the cassette while push-
ing the lever stopper of the holder assembly CST back-
ward. In this case, clog both holes on the housing
rail part of chassis to prevent detection of the end sensor.
If doing so, proceeding to the stop mode is done. In this
status, input signals of all modes can be received.
However, operation of the Rewind and the Review is
impossible since the take-up reel remains at stop status
and so cannot detect the reel pulse (however, possible for
several seconds).

NOTE
Adhere the torque gauge adaptor to the torque gauge for measuring the value.
