D - Test Equipment Flashcards
A resistance reading of infinity or out of limits (OL) indicates a:
Resistance higher than the meter is capable of reading.
A resistance reading of 2.4 M Ohms could be expressed as:
2 400 000 ohms.
The term impedance, as related to electrical test equipment, indicates:
The amount the test equipment will load the circuit.
The first step in operating a digital multimeter should be to:
Read manual.
A low resistance conductor that is connected in parallel with the ammeter’s digital display is called a:
Shunt.
When using the Ohm meter function of a digital multimeter, holding the two test leads together, a reading of … is expected:
0 Ohms
When using a digital multimeter to measure amperage, what protects the meter from having to much current run through it?
Internal fuse.
A high impedance digital meter should be used when measuring electronic circuits to reduce the:
Possibility of circuit damage and inaccuracy of meter readings due to meter loading.
True or False: Measuring the source voltage with no loads connected is known as measuring open circuit voltage.
True.
An … digital multimeter automatically sets itself to the most accurate range within each function.
Auto ranging.
When using a digital multimeter to check … , the meter is connected in parallel to the source of voltage.
Voltage.
When using a digital multimeter to check … , the meter must be connected in series to allow all the circuit’s current to pass through the meter in order to obtain an accurate reading.
Amperage.
Meters equipped with a … have an internal battery to power the meter’s electronics.
Digital Display.
If the … is reversed on a digital multimeter, the digital display indicates a negative ( - ) sign.
Polarity.
You should always have a … digital meter when measuring sensitive electronic circuits.
High impedance.
