MESR-100 ESR Meter | Custom probes for in-circuit measurements

When I was ordering this meter I thought I could just connect my multimeter probes to it and it will work. Unfortunately, the leads must be very short so I made this...

Good point about the RF and short leads, never thought about that - I have one of these, they're great but you're right it is awkward to measure in circuit with the croc clips!

This was my first ESR meter. I found that the tweezer probes from Firgelli automations work well. Its the one with the kelvin clip end. The much longer probes that came with my Bside ESR02 pro also zero out just fine as well. I got myself a blue ESR meter last week from Anatek and will probably give the MESR100 away. The blue esr is a superior piece of equipment in everyway except cost. Keep those videos coming, I really enjoy them.

I love these needles.. I use them on bench and for back probing sockets in cars.. Wires I have factory made with 4mm plugs in both ends.. Expensive, but worth it because of very small resistance..
Didn't thought about making my own LCR meter wires.. 😉 Great tip.

I use the Anatek BLUE. I uses longer leads. I have banana connectors on the ends, and push on crocodile clips. To make them pointy and more precise when measuring in-circuit, I put specially bent "legs" into the crocodile clips. Very versatile this way for any job. Thx for your vid.

Been enjoying your content for a few months now, of course I lurk but keep up the good work.

Very interesting video ! I have this meter from a few weeks and I found it to be not so reliable. Why is changing tested values of the same capacitor ? Even changing the position of the clips : one opposite to the other or one against the other changes the result. I’m taking about brand new capacitor not installed yet so I’m testing connecting to the original “legs” of the capacitor. Same issue for longer cables as you said in the video I cannot calibrate some types . I tried one for smd misurement “tweezer style” and it seems to calibrate but it’s not so easy to mantain a good connection for the measurement time.

Can you please provide links to the parts to make those needle probe wires with the plugs as you have put together?

[rgry]

My MESR-100 has firmware V2.3 and yours shows V3.1. Do you know how to update the firmware and what has changed?

I would have loved it more if the flashing lights were not there! Thank you for the video!

It funny how the price of that meter varies wildy from seller to seller on Amazon. It's a decent meter though.

[bgregg]

For 60 bucks, it should come with your probes.

And now cut off the most from that needle probes....Just leave about 3 to 4 more precise...

You are adding all manner of resistance with those shitty screw type banana plugs extra contact surfaces.
It's much better to just take some (oscilloscope probe) Coax and fit a pair of very short leads to banana plugs on one end, then solder sharp probes on the other end on suitable length flying cables at the other end.
Or even better, add a BNC socket onto the meter, then you can simply plug in a standard Oscillocope probe, and use the spring connection rather than any flying lead.

This thing is a cheap piece of crap. I bought one and returned it the next day. Junk !

Please next time make a short video, you just waste my time!
This video should be 30 seconds max.
