False


A voltage meter measures voltage.

A Continuity tester, is an item of electrical test equipment used to determine if an electrical path can be established between two points ; that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus.

The tester consists of an indicator in series with a source of electrical power - normally a battery, terminating in two test leads. If a complete circuit is established between the test-leads, the indicator is activated.

The indicator may be a electric light or such a device might also be fitted with a buzzer. This led to the term "buzzing out a circuit" (which means to test for continuity). This term remains in use today, although any sound produced is usually made by the beeper function on a modern digital voltmeter.

A popular design has the tester combined with a standard flashlight. A TRS connector or jack plug in the rear of the unit permits a set of test leads to be plugged in effecting a quick conversion between the two applications.

For situations where continuity testing must be done on high resistance circuits, or where delicate conductors and sensitive components that might be damaged by excessive current are present, a low voltage, low current device must be used. These typically use an op-amp and watch batteries to drive a LED as an indicator. These testers can be exquisitely sensitive; for example they will indicate if the test points are taken by both hands.

There are times when a simple continuity test doesn't tell the whole story. For example, vibration-induced problems in automobile wiring can be extremely difficult to detect because a short or open is not maintained long enough for a standard tester to respond.

In these applications a latching continuity tester is used. A more complex device, it detects intermittent opens and shorts as well as steady-state conditions. These devices contain a fast acting electronic switch (generally a Schmitt trigger) forming a gated astable oscillator which detects and locks (latches) the indicator on an intermittent condition with a duration of less than a millisecond.

False, a continuity tester only tells you if you have a complete circuit.

continunity tester will tell you if there is a broken wire or a bad element in what your testing

No, it measures continuity (absence of breaks in the circuit).
It is essentially an Ohm meter (which measures resistance)
So, false.

false, it checks for continuity---to assure that the line is not open or broken; not voltage. If you have a multimeter you simply adjust the dial to whatever you are checking for---amps volts, current. Hope this helps

False,measures resistance.
