Is this actually an ESR meter for checking in circuit capacitors? Or just a capacitor farad measurement tool?

It's just a capacitor farad measurement tool. I don't think your results will be very accurate in-circuit.

This meter is not an ESR tester and can only be used to test capacitors that have been disconnected from the circuit.

Yes, it will read capacitance up to 20 Microfarad (20uF). However you must disconnect/remove from circuit the capacitor you want to test (or at least one lead disconnected). If you try reading a capacitor while installed in a circuit you will get erroneous results.

The unit is designed to measure voltage, amperage, resistance (ohms), dc, ac, at all levels. So whether it is a computer, TV, Stereo, outlets or lights it is a terrific tool to diagnose problems in those areas assuming you know with the readings should be. I used it to measure brownouts in my neighborhood when the power company would lower the voltage during peak demand periods. I saw the voltage drop from a normal 120 VAC to 108 and when I lost some electronics, the power company reimbursed me. As voltage drops current increases (ohms law) so the electronics get fried. I hope his helps.

As far as I know, it can only be used to determine if a capacitor is shorted, by using the resistance (ohmmeter) scales.

hard to tell without isolating everything else on that circuit and then checking with an amprobe or other amperage measuring instrument. It can't be very much.

It can under the following conditions: The circuit is NOT powered-on. The cap to be measured is discharged manually by shorting it for 1-2 seconds before being measured/tested.

It depends on what you mean by "good". It will measure the low frequency or DC capacitance and you can decide if the value is within what you consider the proper spec. However, it will not tell you if the capacitor can withstand the the rated voltage. It also will not tell you the leakage rate for the capacitor. To determine the leakage rate you will have to charge it to a specific voltage, measure the voltage before disconnecting it from the voltage source, and then measure it again some time later, using a voltmeter with a very high impedance front end, so that the act of measuring the voltage won't discharge the capacitor. It also won't tell you the capacitance as a function of frequency. I hope that this helps you.

Don't know but probably not reliably. It would depend on the amplitude of the signals the tester uses to execute the tests and the nature of the circuit that the cap is in. There are lots of comments/blogs out there about this tester if you google around.

yes , it is very easy to read all the voltages, any not with in specs the reading will be in red . I do have the old style tester and bought this one and have been using it ever since. I am keeping my old tester as a back up in case it fails.

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

I have not had any problems with the meter, I am not sure what you are wanting to check the frequency of, but I use it on HVAC equipment and check frequency once in a while and it works for checking that.

I tested it against other emfmeters.No documentation is available. I suppose it measures V/m for low frequencies waves, not. radiofrequencies.It worths price se paid!

You can check both using the ohms scale using any meter checking for shorts or opens and crude capacitor test by observing rate of charge or lack of this meter will do the job if you know what to look for. I use it for these test

I would be lying to you if I said I knew. I'm not even sure what you're asking. I bought this multimeter just for one purpose and nothing else. Sorry, I wasn't much help.

You can but it will activate the circuit because it's probe voltage is too high, so it's really not meant to. If you want to do in circuit measurements get a dedicated ESR meter. The ESR function on this device isn't really very accurate anyway, it's mainly useful for transistor testing and LCR.

There is no metal probe on the end in the sense that a DMM uses test leads with metal probe tips. This sensor works on the principle of a capacitive voltage divider. See Fluke's Web page. http://www.fluke.com/Fluke/usen/community/fluke-news-plus/ArticleCategories/Electrical/CapacitiveVoltage.htm Basically, all you need to do is have the plastic end of the probe near a conductor and if the LED in the sensor comes on you will know the line is live. This sensor will not work for DC and should not be used around high voltage AC circuits.

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.
