Electrical Measuring and Test Instruments
Assessment Unit 33 Solved 100%
What category of electric meter is intended for measurement at the electric meter
base? - ANS-Category IV
Capacitance meters measure the capacitance in a circuit or in a start capacitor. This
is measured in what unit? - ANS-Microfarads
What part of an analog scale gives the most accurate reading? - ANS-The midpoint
of the scale
How can a technician determine what the proper PPE is for a particular application?
- ANS-Read NFPA Standard 70E.
Meter functions commonly used for air-conditioning troubleshooting include: - ANS-
Volts, amps, and ohms.
A technician uses an ohmmeter to check resistance and for a complete path in the
electrical circuit, also known as: - ANS-Continuity.
Root-mean square (RMS) is a mathematical formula for: - ANS-Calculating the
electrical power passing through a alternating current circuit.
An ohmmeter is set on continuity and beeps when the leads are connected to a
circuit. This indicates that: - ANS-The circuit path is complete.
What is a transient voltage? - ANS-A momentary surge or spike of voltage that can
be several times the normal circuit voltage
How are clamp-on ammeters used? - ANS-They are clamped around one of the
power wires feeding the circuit.
How does a weighted average meter measure alternating current? - ANS-
When choosing an electric meter, it is important to use the proper category rating:
- ANS-
How are voltmeters connected to read the voltage drop across a load in a circuit? -
ANS-
