Will this meter test capacitors in circuit and is it accurate when testing in circuit?

No, it will not test capacitors in circuit with reliability. When testing in circuit, you do not know whether there are other capacitors in series or parallel with it. It will give you a "Quazi" check, meaning that if it reads your capacitor value correctly, then you now have the problem of telling whether that capacitor is internally ok. This meter will check the value of a capacitor, but it will not check the internal part of a capacitor. There has been times which this meter shows perfect, but when checking with a OHM meter, the capacitor has a internal resistance of 75K instead of infinity. But, if this meter shows a capacitor being off value by a ways, there is a very good chance the capacitor is bad. Remember, there are 3 things that go bad on a capacitor for the most part. 1. Out Value, out of tolerance (This meter will show it). 2. Internal resistance (This meter will show SOME, but not all of this kind of breakdown). 3. Load breakdown (This meter will not show anything on load breakdown).

will not test caps in circuit, you need an esr meter for that. the newcason is good for out of circuit. decent meter for the price. pretty accurate.

No. You can not test capacitors on a circuit board. It will give you a false reading, other caps on the board will influence the reading. You have to discharge a capacitor before handling it and taking readings from it.

Did not figure it out completely. The instructions were not very good. Avoid it

No, it does not measure F directly. There are methods on the internet which explain how to build a simple circuit into which you can insert the capacitor and then measure the voltage and current to calculate the capacitance. This meter can measure those parameters.

Yes it will test for power as well as continuity just make certain to read the directions to confirm the color and sound that goes with each.

Yes it will. AC or DC. Just clamp unit around positive conductor and select proper current on meter.

This unit will give you a reading of the amount of capacitance of the capacitor(cap) that you are testing. So, If your cap is good it will read close to what it is marked on the side of it, if it is blown it will read no capacitance which will require you to solder a new capacitor into the circuit. I hope this helps!

Yes, for all practical purposes. Incredible, inexpensive device accurately measures R, L and C with high precision. Caps test provides capacitance and ESR (equivalent series resistance) simultaneously, in seconds. There may some electrolytics in high voltage applications that would require leakage tests under the working voltage but these aren't seen too often. In a test, a 220 uf electroyic 63 wv, with a 500 ohm shunt resistor added, still gave an accurate read of capacitance and ESR. This replaces an ohmmeter, cap meter and ESR meter. I am buying another one. Hope this info is helpful.

The instructions with my tester were very basic, but accurate. Written instructions included with any cheap capacitor tester, or multimeter are minimal at best. If you don't know how to use a cap tester it's best not to use one, until you take a class or two, large caps can kill you if you don't know what you're doing.

I test capacitors on the MfR setting and it is very close to the factory capacitance, it will also pick up leakage voltage down to 1 volt. Best meter after 42 years that I have ever owned.

Yes this Meter will measure 60 hz at 120 volts BUT BE VERY CARE THIS VOLTAGE CAN KILL YOU !!!!! Also this is not a true RMS meter so it will measure the peak to peak voltage only

I am not really familiar with the procedure for testing aquarium lights, so this is hard to answer. The bottom line is that this meter will measure for comparison light readings, based upon differences in the source of the light. I hope this response is useful.

I do service work on ac equipment and use this to check run caps. the reading in almost instant on these types of capacitors.

It will verify your voltage but not your sine wave. Are you trying to measure frequency or peak waves?

This type instrument will only tell you the capacitance of the part. It will not tell you if it has insulation leakage. If it is shorted it would likely not be able to measure a capacitance, so that would be another indication that a capacitor is defective. Testing for insulation leakage is not easy to do without a more expensive capacitor checking instrument designed to measure that parameter. Power factor is another parameter that may be important to electric motor start/run capacitors and again requires a more sophisticated instrument to measure.

Yes, this would be an excellent use for this tool. Be sure to check a known power source such as a receptacle to ensure the tester is working properly.

It would tell you if it is charging, but not if it was leaking. I use it for basic testing, and it is great for that, but would not rely on it for testing capacitors.

I use a voltage meter to test the output of the charger when there is a question of the efficacy of the charger.
