5.16 NOMINAL/VARISPEED
When the NOMINAL button is pressed the LED lights up and the machine
will transport the tape at fixed nominal speed of 15 or 30 ips,
whichever has been selected. When the VARISPEED button is pressed the
LED flashes continuously to warn of a non-normal condition; the speed
of the tape now depends on the setting of the two potentiometers below
the VARISPEED button. As indicated they allow COURSE and FINE
adjustments of the tape speed from slightly below 7 1/2 ips to
slightly above 60 ips. A further feature of both buttons, in
combination with the TAPE TIMER display allows for checking the actual
tape speed. This is operated as follows: Select either the NOMINAL
speed or VARISPEED. Do not release the selector button but hold it
down. In this position the TAPE TIMER display will change over to 4
digits which express the actual tape speed according to the following
formula:
1000
speed ips = 15 x
2.000 - DISPLAY
Table 1 and 2 shows the full range of the displays with their
equivalents in speed deviation in ips, in percentage or in musical
values. This speed checking function may be used to reset any
VARISPEED setting at any time within close tolerances.
An important feature of this function is that it does not disturb the
TAPE TIMER counting. When the button is released the timer will go
back to its normal timing function without having lost count in the
interval.
Note: No reading will result if the tape is not in motion,
since the information is taken from the TAPE MOTION SENSOR,
therefore reflecting the actual tape motion, not the capstan
motor speed.
