BSIDE ACM91 Digital Clamp Meter 1mA AC/DC Current True RMS Auto-Ranging 6000 Counts Meter Hz Temperature Capacitance Live Check V-Alert Low Impedance Voltage Tester

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.

Bought this mainly to help diagnose parasitic battery drains in cars, boats and tractors. Most clamp meters at this price do not have a low DC current function. Useful on more modern vehicles and the simple act of disconnecting the battery to put a standard multimeter in series with one of the battery terminals wakes up ECUs on the vehicle and causes a higher current draw, meaning you have to wait (sometimes for long time) to get the car to power down and give you a baseline current reading. Using this clamp meter avoids that issue as you don’t need to disconnect the battery. I found it to be fairly accurate, certainly good enough to pick up 50 milliamp (or even less) draws and help me locate which module or system on a vehicle is not shutting down and draining the battery. I also use it on my cheap stick welder to set the current for welding thin (1mm or less) steel box section The cheap inverter welder readout is not accurate, with this clamped around the stinger lead I can dial in 20 or 30 amps and know it's correct. Would recommend this clamp meter for the money, I’m glad to have it.

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

Electrical testing

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.

Not bad for the money I just need to check for a reading. I’m not too worried about it being too accurate.

Not one single function works should have known better with 40 year's in the trade stay well clear
