HantekCC-65 AC/DC Current Clamp Meter Transducer for Digital Multimeter Oscilloscope with BNC Type Connector

This inexpensive clamp-on DC current probe works with your oscilloscope to view transient DC currents. We used it to diagnose a video camera that pulled a high surge current from a DC source. In the photo attached, we had a current pulse of about 12A for about 800 usec. We could not have found this without this product.

I was not expecting a high precision current probe at this price and this is as good as it claims!The accuracy is reasonable, though zeroing is a bit finicky (as described in the instructions ;-)). Zeroing is, of course, most important at the low end of its current range but even there, measurements are repeatable making it fine for relative measurement and comparisons. Though it will detect signals below 20mA (it's rated low end) it is pretty noisy so of limited use.I tested it across its frequency range but not the high end of its current range. It is pretty linear with some distortion appearing as its response starts to roll off near the high end of its frequency range. It works fine with my bench DMM and oscilloscope, though my intended use is primarily with the latter.Definitely a good value. Unless and until I need higher accuracy or range, I would buy another if it fails. If you are even looking at this you know that to get a clip on current probe significantly better would cost much fine gold.Believe the specs and if you think it might work for you, go for it. It probably will and it won't break the bank.

Watch the YouTube video to see how it works with a VOM meter. You'll need to use BNC to banana plug adapter. It didn't ome with one. Got to remember to set the VOM to the DC volts scale because the clamp converts the current to a DC voltage. Separate the wires in the power cable and clamp the sensor onto one single wire of the power cord , not to all 3 or 2 wires or to the ground wire.

This is a great addition to a scope or multimeter with a BNC to banana adapter. I've checked battery charge current, appliance power load, plenty others. Yes it's pretty light plastic, and the zero button doesn't inspire confidence, but I'm very happy with it's performance.

What's good:Pretty accurate (within a few percent at low frequencies, although zero drifts a bit) except at low currents.Low price for a current probe.What's not:Clunky design. Probe won't fit in tight spots.On/off/range switch and zero setting control are poor qualityI haven't had time to use this very much. However, I did a quick set of tests using a square wave current of 1 ampere at various frequencies. The rise and fall times of the current probe signal were both about 10 microseconds, which corresponds to a bandwidth of about 30 or 40 kHz. (The rise and fall times for the current signal I generated were both 1.2 microseconds, an order of magnitude shorter than those of the probe.)I also tested it briefly at much lower currents. Down to about 100 mA it's pretty good, although the signal is quite noisy. As currents drop below this level, I would have less confidence in the readings because of uncertainty about the zero setting and the noise in the signal. The noise produces a trace that is about 3mV thick, which corresponds to a current of about 30 mA.

I used it with a DSO150 portable Digital Oscilloscope.Probe is attached to my Positive Car Battery Red Main Wire.I remove the Fuel Injection Fuse.(i do Not want the engine to start)Then i crank the engine starter motor to turn the engine pistons.This Amp reader then measures the Amps needed by the starter in order to make each Cylinder Compress the Air inside.If one of the cylinders has Low Compression, then that one will require a Lot Less Amps to compress because it has piston rings that are LEAKING and need to be replaced (very expensive).-------Worked Great-------All 6 Cylinders have the Exact same amount of Amps needed to compress their Air.-------Scotty Kilmer on YouTube Explains how to do All of this.-------Super Awesome

I got this 60 amp current probe to use with my Picoscope 2204a. The Pico current probe was unavailable, so I ordered this one to use for automotive diagnostics. I later did get my hands on a Pico brand and ran both simultaneously on each channel. The waveforms were identical, as you can see in the photo. This one costs less than half of what the Pico costs and is every bit as accurate. It is well built and the only real difference is the BNC cord is shorter, which I actually prefer. Long cords in engine compartments can be hazardous. I am so impressed with it I have also ordered the 600 amp probe for higher current circuits. You really can’t go wrong with Hantek probes.

I really like this probe. For all practical purposes, it fits the bill as a substitute for the $2000+ Tektronix probe I use at work. DC offset and accuracy aren't the same of course, but when you only need to verify the 35A waveform is present it fits the bill. Seems to be within a couple of percent of the good stuff.My only complaint is that it doesn't shut off by itself. I bought some rechargeable 9V batteries because I almost always forget to switch it off and have to change out the battery every time I use it.
