6.
when seeking to measure the voltage of an industrial power supply (600 Volts AC) an
electrician needs to do the following to prepare the Simpson 260 meter for
measurement (insert the words to make the following statements correct).
a. Set the function switch to
b. The black lead should be inserted in the
jack.
C. The red lead should be inserted in the
jack.
d. The range switch should be set to the

Did you note the safety warnings in this section? Fairly significant, eh?!
Nothing to mess around with!!
7.
Why must you "zero" the meter (adjust it for zero (0)) when measuring resistance?
8.
Describe the steps needed to accomplish the task of zeroing the meter. (4pts)
For the following questions, refer to section 4.19 in the Simpson meter manual.
9.
The Rx 1 resistance range is intended for resistances between
and
Ω.
10. The R x 100 range is intended for resistances between
and
Ω.
11. The Rx 10,000 range is intended for resistances over
0450…
Question 3:
Suppose an engineer designed a fire alarm system for a large warehouse, with multiple
pushbutton switches connected to a single alarm siren:
Siren
Actuating any of the normally-open switches results in the alarm sounding. So far, so good.
Now, suppose that one of the wires connecting one side of several switches to the rest of
the circuit breaks open. What will the result of this failure be?
Siren
break!
