1. All ECE laboratory reports shall follow the format outlined on the EE

laboratory Cover Sheets (bookstore).

2. No food or beverage is to be brought into the EE laboratories. Smoking is not permitted in the laboratory.

3. Safe engineering practice shall be followed in all experimental work. Particular care shall be taken around

line voltages, electrical machinery and special apparatus. All instructors and students shall know the location of the

main disconnect for their laboratory area.

4. Laboratory periods are assigned for specific classes. The heavy use of the laboratory facilities makes it

virtually impossible to reschedule any laboratory. Instructors shall weigh laboratory participation as part of the

course grade.

5. Students may work in the laboratory only with proper supervision. Stu- dents wishing to use an operating

laboratory shall request permission from the instructor assigned for those periods. Work accomplished outside the

normal class period shall be signed by the instructor who is assigned for those periods.

6. Defective test equipment shall be tagged by the instructor after verifica- tion that the item is not

functioning properly. Instruction books for all equipment may be borrowed from the ECE stockroom library for

use during the laboratory period. They must be returned to the ECE stockroom before the end of the period.

1. Never hurry. Haste causes many accidents.

2. Always see that power is connected to your equipment through a circuit breaker.

3. Connect the power source last. Disconnect the power source first.

4. Never make wiring changes on live circuits. Work deliberately and carefully and check your

work as you proceed. 5. Before connecting the power, check your wiring carefully for agreement with the wiring diagram

for an accidental short-circuit and for loose connections.

6. Check out the supply voltage to make sure that is what you expect. For example: AC or DC,

15V, 20V, or 25V

7. Do not cause short-circuits or high currents arcs. Burn from arcs may be very severe even at a

distance of a few meters. Report all electrical burns to your instructor.

quipment

The tools used in measuring the voltage characteristics of incandescent lamps :

1 . Screwdriver ( + ) and ( - )

2 . Tang combination

3 . Tang paring Isolation cable ( crocodile forceps )

4 . AVO meters

Materials needed to measure the voltage karakteristrik incandescent lamps :

- NYM cables ( red , blue )

- 1 piece induction regulator .

- 1 piece AC voltmeter with a range of 300 V.

- 1 piece AC ammeter with a range of 0.25 A .

- 1 piece MCB board .

1. Counting to determine the measuring instrument.

2. Measure voltage load power.

Dik : P in = 100 W incandescent lamp

V = 220 voltsDit : i?

Ans:

I = P / (V)

I = 100/220

= 0,45 A

Prepare tools

Connect in accordance with the design drawings.

Measure the results of the work

Arrange results. .

If there is something that does not make sense in the results, do the

measurement again.

Connect the stop contact 220 Volts on the

mcb (at MCB input)

Then, connect the MCB for output on input

regulator

Connect the output on terminal positive

regulators on the voltmeter gauge.

Connect output negative voltage regulators on

terminal limits measure on the voltmeter

gauge.

On the terminal on the voltmeter gauge,

connect the terminal to the on theamperemeters gauge.

After that, the terminal limits measure on the

amperemeter gauge, connect again to the

incandescent lamp ( the positive voltage to

the lamp ).

And at the limit of measurement inmeasuring instrument voltmeter, connect the

lamp on again can light up. ( the negative

voltage to the lamp ).

Characteristics of the incandescent lamp when its voltage is above 50 V

then the conclusion is already bright lights and when the voltage is below

50 V then the dim light of the results of these measurements affect the

voltage of the incandescent lamp.
