Hantek AC/DC Current Clamp Up to 20 kHz
- Model Name: CC-65
- AC/DC frequency range: Up to 20 kHz;
- Effective Measurement Range: 20mA to 65A DC;
The current clamp is a transducer, which allows your multimeter to measure current data and enable your oscilloscope to measure the current waveforms accurately.
Brife Introduction
- When measuring the AC/DC Current with the Current Clamp, a multimeter or scope can directly measure the current up to 65 A , with a frequency up to 20KHz;
- In this method, there is no need to break a circuit or to affect the isolation to measure the current;
- The Current Clamp is not only available for the detection or monitor of the possibly existing creepage, but for the measurement with little gap using its extended jaws;
- However, it is necessary to turn the zero adjustment knobs on the clamp until the multimeter or scope reads zero.
Load Resistance:
10kΩ Typical
APPLICATION SAFETY
- The voltage of the conductor measured with the current clamp should be little than 300V DC or 240V rms AC;
- We are forbidden to measure the conductor whose insulation has break down or wear down.
Key Features
- AC/DC frequency range: Up to 20 kHz;
- Effective Measurement Range: 20mA to 65A DC;
- Accurate circuit measurement and suitable for DSO;
- Friendly in use: turn on, clamp it over a conductor, and get a reading;
- Output: BNC connector;
- Take accurate current readings without breaking the circuit;
- Soft non-slippery over mold handle;
- Nice and accurate current clamp;
HOW TO USE
- When connected with any multi-meter or a scope,connect the BNC connector of the clamp to a scope BNC connector;
- Set the power switch form “Off” to “ON” position, that is to set the multimeter range to 1mV/10mA or 1mV/100mA. Then, the green LED will be lighting, indicating that the clamp is switched on;
- when the current is not greater than 2 ampere ,please set the current clamp range to 1mV/10mA and set the multi-meter range to 200mV AC or 200 mV DC, which depends on the type of the current;
- Before measuring the DC current, it is needed to turn the zero adjustment knobs on the clamp until the multimeter reads zero. That means pushing down the zero adjustment knobs on the clamp until the multimeter reads zero. Then let go hold of the zero adjustment knobs.When using a scope,set DC coupled mode to measure DC current;
- Clamp the jaws around the current-carrying conductor and operate as above;

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.

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.

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.

I was pleasantly surprised when it actually reads DC current using my portable oscilloscope! The price is very good for a DC/AC current clamp.

Even at micro-Second (uS) speeds the measurements seemed to be accurate, even for DC voltages. Doesn’t auto-power on or off, so you need to remember to use the switch. Requires 9V battery (not included).

I got this to try with me new oscilloscope and it seems to work fairly well. Build quality could be better, the zero button tends to get stuck easily, bit is also easy to fix. Comparing to my USB meter as well as my power supply meter it seems to be pretty accurate even The signal is pretty noisy, bit from what I've seen that seems to be expected with these.

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 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.
