LADWP Meter Reader (Class 1611) Exam Questions
and Answers| Updated| Pass Guaranteed
1. What does kWh stand for?
A. Kilowatt-height
B. Kilo-water-hour
C. Kinetic watt hour
D. Kilowatt-hour, a unit of electrical energy
Answer: D. Kilowatt-hour, a unit of electrical energy
Rationale: A kilowatt-hour is the energy used by 1,000 watts operating for
one hour; electric meters record it.
2. Water use on a customer's meter is commonly recorded in:
A. Hundred cubic feet (HCF/CCF) or gallons
B. Kilowatts
C. Volts
D. Amperes
Answer: A. Hundred cubic feet (HCF/CCF) or gallons
Rationale: Water meters register volume. One HCF equals about 748
gallons.
3. A dial pointer is between 4 and 5. What digit do you record?
A. 5
B. 4.5
C. 4
D. Either 4 or 5
Answer: C. 4
Rationale: When a pointer is between two numbers, record the lower
number it has most recently passed.
,4. Adjacent dials on a clock-type meter usually:
A. All turn the same direction
B. Turn in alternating (opposite) directions
C. Do not move
D. Turn only at night
Answer: B. Turn in alternating (opposite) directions
Rationale: Alternating directions come from the gear train, so you must
note each dial's direction when reading.
5. A pointer sits directly on 7, and the dial to its right has just passed
0. What do you record for the 7 dial?
A. 6
B. 8
C. 0
D. 7
Answer: D. 7
Rationale: If the next-lower dial has passed zero, the pointer on the higher
dial has truly reached its number, so record 7.
6. A pointer appears to be on 7, but the dial to its right is between 9
and 0 (has not yet reached 0). What do you record?
A. 7
B. 8
C. 6
D. 9
Answer: C. 6
Rationale: The right-hand dial has not completed its turn, so the higher dial
has not yet truly reached 7; record 6.
,7. A pointer is between 9 and 0. What do you record?
A. 9
B. 0
C. 1
D. 10
Answer: A. 9
Rationale: Between 9 and 0 the pointer has last passed 9, so record 9.
8. A cyclometer (odometer-style) register is read:
A. Right to left
B. Left to right as you would read numbers
C. Top to bottom only
D. By listening
Answer: B. Left to right as you would read numbers
Rationale: The digits display directly and are read left to right like any
number.
9. A meter reads 2,500 and has a multiplier of 10. The customer's
actual use is:
A. 250
B. 2,510
C. 25,000
D. 12,500
Answer: C. 25,000
Rationale: Reading x multiplier: 2,500 x 10 = 25,000.
, 10. Previous reading 04567, current reading 04892. Consumption is:
A. 335
B. 315
C. 4,892
D. 325
Answer: D. 325
Rationale: 4,892 - 4,567 = 325.
11. On a 5-digit meter, the previous reading was 99850 and the current
reading is 00120 (the meter rolled over). Consumption is:
A. -99,730
B. 270
C. 120
D. 100,120
Answer: B. 270
Rationale: (100,000 - 99,850) + 120 = 150 + 120 = 270.
12. A demand meter measures:
A. Peak power in kilowatts (kW)
B. Water pressure
C. Gas flow
D. Voltage only
Answer: A. Peak power in kilowatts (kW)
Rationale: Demand meters record the highest rate of electrical use over an
interval.
