ACM91 1mA Clamp Meter AC/DC Current True RMS Auto-Ranging 6000 Counts Voltmeter Temperature Capacitance Frequency Live Wire Check V-Alert Tester with Back Clip

A good all round handy meter, easy to use at a great price.

Bought this as a cost effective device to check earth leakage on badly configured CU that was tripping all the time. It gives an indication of unbalance, but it seems to be way to high to be accurate. Normal single wire AC current seems to be reliable. DC current readings are useful but again, as another reviewer noted, vary quite alot on small currents.The 'Live' check needs the operator to hold the unit as it appears to require a capacitive earth connection - like the neon testers but with a less tingly current! IE you can't use the probe and leave the unit on the bench.The extra flanges for holding the probe for 'Live' testing can get in the way in tight spaces. I may have to cut them down...Overall, though, nice tool for the price.

Small Easy to use, and seems to be pretty accurate....Impressed with AC & DC capability, assume it must be a hall effect device.Impressed with the resolution of 1mA ..... (fsd 6A) .The AC accuracy is ±(2.5%+5) which is pretty good for a clamp on !!

You can always get AC clip ons for a reasonable price but to find a DC one at this price is pretty good. I like the fact that it has probe holder built in too like the expensive one my company bought me. The accuracy is good as well for a sub £100 meter. Definitely worth buying if you check a lot of DC current like in automotive, electronics etc.

Having read alot of reviews oin this producxt I thought I would add mine.I bought this to measure DC current on the low end.The first thing I did when this clamp meter came through the door was to test the meter and the photo says it all. The meter once zero`d with the wire in place and no power going through it was accurate to within 1mA which I thought was amazing for the price.I carried out a further 5 or 6 tests at various current settings between 50mA and 700mA and all were more than acceptable (+/-2mA).You can`t go wrong with this product.One caveat I should mention, I have not measured the accuracy of any of the other features as I`m really only interested in the clamp current.

As described nice piece of kit work well and functional

At nearly £50 I presumed this would be good. It arrived promptly but did not work displaying either nothing or a backlight only or a frozen display that did not register voltage when turned on. Item returned.

Whenever you are going to buy a DVM (digital volt meter) you are faced with an array of decisions. What functions do you want to measure, to what accuracy do you need and how much do you want to pay?With a DVM you can pay 5 x + the cost of this handy tool (for a Fluke meter) and for the clamp ammeter facility you will need to pay £120 for the Pico clamp ammeter and will need an oscilloscope to attach it to.I primarily chose this meter for a number of reasons:-The clamp ammeter Jaws were not too large/wide (16mm) this gives higher accuracy when measuring small current flows. I use them for checking vehicle DC battery parasitic drain, which should be 20-30 milliamps and alternator charging current, normally 60 amp max. I noticed that the amp scales were 600 milliamps/6 amps/60 amps/100 amps perfect for vehicle current ranges. I had not noticed that the 600 milliamp setting was for AC only but the higher three were AC/DC.On the Volts/Ohms/continuity beep setting, I liked the auto set facility which made it quick and simple to use. Also the the LIVE setting was excellent for checking caravan/motorhome mains hook up wiring on 240v.Unfortunately on the first meter I was supplied the voltage reading was innacurate and gave me a reading of 11.9volts on a 12.4volt car battery. I as a consequence had to return the DVM, but I was impressed at the level of after sales service provided by MAXRIENY-UK. Who demonstrated great concern at my disappointment and very quickly supplied an accurate unit for me to use.It is a shame the 600 milliamp scale is not DC compatible it would make this little tool perfect for my needs, but I am unable to find any other reasonably priced DVM available anywhere that better meets my needs/original requirement.
