TM 5-3610-253-14
5-23.4 Direct Linear Scale Measurement System. Moves directly with the backgauge
to give a direct digital readout of the distance between the backgauge rake and
the cutting line. It is comprised of:
a. LED measurement display. Provides a constant display of the distance between
the backgauge rake and the cutting line after the backgauge has been moved across
the reference point. The display is accurate to within a hundredth of an inch. The
last position of the display indicates the direction of movement of the backgauge.
If the backgauge is moving to the rear, a "+" sign is shown. If the backgauge is
moving forward, a "-" sign is shown. The LED display also shows error messages when
a malfunction is present in the paper cutter.
b. Linear scale. Provides the scanning device with pulse signals. Has a
reference mark which is used to reset and insert corrections into the TAM circuits.
c. Scanning device. Picks up electrical signals from the linear scale. It is
attached directly to the sledge and moves along the linear scale.
