selective collective elevator [Hint: Answers the first call entered answers
control? down calls when traveling up answer calls
sequentially in the direction of travel answers car
calls first then returns for Hall calls]
3 Which of the following statements Function switch to A~ ,red to lead to 10a jack
correctly describes how to black lead to com jack [Hint: Function switch to
measure AC current with a digital V~red lead to 10a jack black lead to com Function
meter switch to A~ red lead in com jack black to 10a
jack Function switch to A~ ,red to lead to 10a jack
black lead to com jack Function switch to A- red
lead to VO jack black lead to com jack]
4 What does the symbol below An scr [Hint: An scr A check valve A zener diode A
represent? varistor]
5 How is voltage tested with an With the leads connected in parallel with the load
analog meter [Hint: With the range selector switch to R X1 with
the range selector switch set to 100 MA with the
leads connected in series with the load with the
leads connected in parallel with the load]
6 After removing power what else is Remove one lead of the component from the
necessary before testing circuit [Hint: Plug the red lead in the 10 a jack
resistance of a component in a remove one lead of the component from the
circuit circuit both component leads must be isolated
from the circuit connect the multi meter leads in
series with the component]
7 With the digital multi meter set to An open coil [Hint: Circuit voltage is too high
the scale and the meter leads circuit current is too high A shorted coil an open
across a coil what would a reading coil]
of O.L. Indicate?
