You wish to examine the intermittent operation circuit. Where do you find it?
a. On the front panel.
b. Mounted on heat sink number 2.
On the printed circuit board.
You are checking the intermittent suction mode of operation with external power.
The suction-mode, suction-level, and vacuum-regulator lamps are lit and the unit
is cycling on and off every five seconds. Next, you pinch the vacuum hose. What
should the vacuum gauge read?
You are calibrating the maximum low-vacuum-level limit function of the
programmable suction pump. You select continuous and low-level modes, seal
the rear-panel vacuum inlet, and achieve a reading of 200mmHg. How do you
achieve this gauge reading?
a. By turning the vacuum regulator knob fully counterclockwise.
b. By turning the vacuum regulator knob fully clockwise.
By adjusting resistor R2.
d. By occluding the rear-panel vacuum inlet.
