I have a 2005 Buick Lacrosse that had a battery going dead if the car sat for 2 days. The dealer charged me $90 and told me they couldn't find anything wrong. I bought this meter and in 30 seconds I saw the car was drawing 500 ma of current when parked (it should be about 20 ma). I pulled the fuse for the radio and the current dropped to 20 ma. I haven't had a dead battery since. Now I need a new radio.

My Battery on my GM car was always low on voltage and charge even though it was new.

I suspected 'phantom' currents were sapping the battery when the engine was not running because charging voltage was within specs. Not wanting to go through the 'pull a fuse at a time' procedure to check for current draw I purchased the ES 687 current probe and Digital multimeter.

Beautiful, withing 30 seconds I clamped the probe around the negative cable of the battery with the engine off and read only a normal 35 milliampere drain. It was not battery current leakage but something else! Probably city start-stop driving.

The current probe measures current through a wire WITHOUT cutting the wire and inserting a meter. Just clamp the probe around a AC or DC carrying wire and read the current. There is also a standard Digital Multimeter and a few extras like frequency measurement.

I did get fooled until I read the instructions.... You need to ZERO (push a button) the meter In The LOCATION that you are going to measure current. Do that and it works great! All the metal influences under the hood have to be canceled out before you get an accurate reading.

Included are a couple of automotive type fuse adapter loops. Pull the fuse, insert the adapter in the car fuse socket, insert the car fuse in the adapter and clip on to the wire loop with the instrument to measure current flowing through the panel fuse. Neat!

I'm going to check the AC and DC currents around the house and see how much things really do draw at idle...

Typically you clamp around JUST ONE WIRE to measure current. With a sharp knife I carefully split a portion of several cables so I could get at just one wire.

I'm very happy with this product...

This is a nice product. The opening in the clamp is however, NOT 1". So if you are looking to measure the amps on your RV battery cable, look elsewhere cause it probably wont fit.

The ESI-687 I purchased arrived defective. When the zero button is pressed it displays -350ma, pressing it again sometimes zeros it, sometimes it doesn't. Immediately the display count increases by 1ma per second and continues to increase on and on. It does this regardless of location and it not exposed to any magnetic fields. Currently am attempting to return it for replacement.

UPDATE: I received the replacement and it works great. No problems now.

The ESI Amp Probe works very well. It allowed me to find stray currents that were draining my household boat batteries. The only down side is that it can not clamp onto wires larger than #2.

I probably will try to sell this item off even though it has alot of features. When I bought the item originally my intentions were to use it on my job for checking parasite draw on the cars I work on without having to disconnect the battery cable, but the hole is so small in the inductive clip that I have not found any vehicle I can use it on. Very disappointed, make the hole larger please!!! Most vehicles have larger cables and so confined that you cannot move further down the cable because there is no access to them making the inductive clip useless. Didnt need another ohmmeter since I already have a fluke.

This meter works as expected with the exception of accuracy. It reads about 10-15 milliamps high on all tests on the 4 amp scale which is borderline acceptable.
