ESI 695 80 Amps DC/AC Low Current Probe

I've used this current probe in my Automotive classes for several years now. Work great and is an excellent value for the money.

So far, I've been successful with this clamp attached to a Snap-on scope. It has matched the accuracy of more expensive clamps, and is quick enough to capture useful current ramps from coils and injectors. It has a larger jaw diameter than some other low-current clamps, so on some vehicles you can even use this clamp as part of your parasitic-draw test plan.

I have purchased a couple dozen of these over the past 3-4 years. We have hundreds of students and these are used many times a day by people who just learning how to use them. The main reason I keep buying this brand is the price and the "auto-off" feature. I really am happy not to replace the battery every time someone leaves one of these on. (This used to happen every single day).If there was another economical alternative with the auto-off feature, I would buy it because these are not that great. My biggest gripe is that they last about 6 months, and then the lead develops an open circuit right at the base where it enters the clamp. For a while we can wiggle the wire and get it to work, but this is frustrating. We have tried repairing the leads, but the same problem returns before too long.We have tried to prevent this problem by reinforcing the leads on the new clamps when they are new. This also helps, but only for so long. I have used many others brands of clamps, and I realize that all are susceptible to this problem, but this particular clamp seems to be especially prone to it.

The auto shut off feature is good, but be carful- while you are taking your time and hookning up the equipment and researching the problem it will turn off and give you no reading... make sure it’s on ;)

Works great. Just need to remember it has an auto timeout setting, so you don't get confused when it shuts off!

unstable mV output, won't reliably zero or hold at zero on 20mA DC scale; output jumps randomly even before it is placed over wire loop so erratically that it is not possible to use this for parasite draw diagnostics; the 80mA scale seems stable but is useless for parasite diagnosis; i tried this on 2 different DVM's with same erratic output (one of which is a Fluke 88 that holds zero perfectly on 400mV scale before this probe is plugged in) - will return it

Excellent price, a Good solid piece of Diagnostic Equipment. Hard to beat the Quality and Ease of use. I use mine mostly for Automotive testing. Like any tool you must become familiar with it's limits and know what you are trying to find out. There are several good books on using a Low Current Probe so don't be put off if you are not confident at first. The more you can use it the more comfortable you become.

Did the job for me but the auto-off feature was a problem when testing for long periods of time.

The only issue is that the included battery lasted about 20 minutes. But a new alkaline battery fixed that.

Handy diagnostic aid, hopefully won't be used very often.

parfait, fonctionne tres bien avec un oscillosope snap on modis
