Continuity is checking for a completed circuit including a short circuit. Checking resistance would be checking in ohms resistance of a circuit, motor windings or an open circuit.
Yes

Pneumatic pressure testing of pressure vessels is done to check the leakage for any leakage where as hydraulic pressure testing is done to check the vessel for its strength.
Strain gage and Extensometer both are same purpose to check the stress and strain in selective test pieces, but traditional they were using strain gage its take the preparation time is high and Extensometer we are check the directly both results are same.
The longer wire is the positive end, but if the wires are the same length, check inside the LED. There are two easily seen parts connected by a wire, the smaller is the positive.
To measure resistance, and to check continuity.
If the electrical box is grounded, check with a tester, the "hot" wire will have a voltage to the the grounded box the neutral wire will not. If the box is not grounded, with the breaker supplying the voltage turned off, use a tester on the resistance scale to check for continuity between the wires and a cold water pipe or some other grounded medium. The neutral will have continuity between the wire and a ground the "hot" wire will not.
The TPS on a 1990 is a WOT switch. Using a multimeter set to read resistance, or a continuity tester, check the resistance between the center and bottom terminals of your TPS with engine off and throttle closed completely. You should read continuity (or zero ohms) between those two terminals, and if you manually open the throttle slightly, the continuity should be lost (resistance goes to infinity). A complete test takes more time; the manual states that with a 0.016" feeler gauge between the throttle lever and the throttle stop screw, you should read continuity, which should go away if you put a 0.027" gauge in there. With the throttle fully open ("WOT"), there should be continuity between the top two terminals of the TPS. In between the idle and WOT positions, there should be no continuity between any of the terminals
Check each fuse with a continuity tester - Set to OHM's Remove each fuse and connect leads to fuse - a good fuse with show continuity "0" resistance while a bad fuse will show "Infinity" resistance
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
A coil pack can be checked for continuity and resistance with an ohm meter. But for heat or load failure the only way to check a coil pack is to replace it.
check resistance, voltage signature and frecuency on the sensor, continuity on wiring and timing marks on camshaft
The way I understand it, a continuos function is said not to be "uniformly continuous" if for a given small difference in "x", the corresponding difference in the function value can be arbitrarily large. For more information, check the article "Uniform continuity" in the Wikipedia, especially the examples.
A: CONTINUITY check is not used to ascertain ohms value but rather the connections
First check the pressure of low and high side, for R22 they should be around 60 and 250 respectively. Second check the temperature of the compressor by touching it lightly from bottom to top. where you can feel the level of oil present in it Third .(Cut the power supply before touching it) if the compressor is not running at all, check the electric continuity between terminals and body, if no connectivity is checked then check resistance between terminals of compressor
A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. This instrument will let you check to see if there is voltage present on a circuit.
