Does this meter show the direction of the magnetic field induced in a coil. If the ends of a three phase motor leads were interchanged, could this met

No, it simply indicates the magnitude of the field, not its polarity, and is good only on AC-produced fields.

This question is a little over my head, but I'm fairly certain that this meter has a single axis that it scans on. As you look at the device's 'face' the axis would be a left-right plane through the meter. Therefore if you turned the meter on its side, you would invert the axis by 90 degrees for an up-down axis. I hope this makes sense.

I just put an ohmmeter across the heavier gauge black and white leads of my meter (out of circuit and powered down) and I got a dead short. So yes, when powered off, the meter will pass current through the black and white leads.

Yes. You can search amazon for a current transformer, sometimes called a current tap. There are closed types that slip over the wire (usually cheaper) and open types that can be snapped around the wire like a regular clamp on ammeter. I don't know the ratio that you need for this meter. I suspect that it is a 100:0.1 ratio. This means that when the wire you are measuring is running 100 amps ac, the output from the current is 0.1 amp ac. If you are planning on switching between current sensors so that you can use one meter to measure multiple wires, you do need to be careful. The open circuit voltage on the current transformer can be dangerously high. I've been tempted to do this but have decided against it.

Yes, the instructions are unclear if you even get a sheet with it. Basically the Source side is the battery, the Load side is the motor side. I use Deans connectors for my RC planes so the appropriate male and female connectors need to be soldered in place. Aside from the lack of instructions, the meter works well and will give you the information need to see what your motors are drawing with full power.

No you can measure voltage and current and it is a true rms meter but you cant measure both at the same time.

I don't know for sure, but i am almost sure it doesn't. This range of current is very small and if it does measure it, it will not be accurate. I will recommend a multitester for this range of current, not a Clamp Tester. you cannot measure current with the test leads con this model, only with the clamps, and it will not be accurate

Sorry I never changed fuses in this meter. But I' will look & if I find out I'll let you know. Bill

The meter must have its own, separate power supply. I use a 12vdc transformer plugged into my inverter and it works great. I am able to monitor amps used by the inverter and other DC loads connected to my batteries as well as switch to see battery voltage. If you already have a separate power supply, you may have a bad meter.

The meter package I purchased included the thermocouple accessory, which had a plug that would connect in the Red voltage(+) and Black (-) common receptacles. It would be possible to probe with the Red and Black test leads that comes with the meter directly to the leads of a J-K thermocouple for troubleshooting purposes. Otherwise you will need to to purchase the a thermocouple accessory from Kline.

The amp meter needs the coil to have one lead of power fed thought it . Using AC I assum. Voltmeter one lead to ground and other to Hot side of AC.

Must clamp one separate wire. It measures the magnetic field due to current flow. Coupling the return wire also will cancel the fields.

Yes.I purchased two of these meters and found that Amazon sold this item for less than three bucks shipped:Male to Male J Connector Servo Extension for RC Air Plane 100mmBasically, you get two plugs for less than 3 bucks if you cut the wires in half.The plugs take a little care when you insert them, but it makes short work of getting power to the memory circuit.Remember there are 3 wires. A hot, a ground and one to momentarily touch to ground, resetting the meter to zero.

You shouldn't have to. So, there's a stray current you are measuring, or there's something wrong with your meter. I'm assuming you only have one wire going through the jaws, and that you have the wire centered as best you can. Is your reading off in all ranges?

This device actually does work by measuring the inductance or induced magnetic field surrounding an energized conductor. I have never heard of it referred to as an inductance tester though.

I soldered a short piece of #14 solid wire to the two voltage leads and covered with heat shrink tubing. Then I put these leads under the lugs of my sub-panel(feed from my generator) to read the incoming voltage from the generator.The meter comes with a coil which is placed around the circuit wire, this generates a very small current in the coil which the meter converts to the actual amperage, therefore the coil wire is carrying very little current. I hope this helps.

It does include leads... But, they didn't last long. the Negative lead broke shortly after I installed it.. You may need to replace them... I found some on EBAY for about three dollars. However, the meter is excellent.

I do not know. You can be the one to test the idea. If your V U meter (probes contacting the power input) reads a current as you spin the prop reverse of its normal direction, then yes. If it breaks then no.
