Review on BSIDE DC Current Clamp Meter 6000 Counts: Digital Multimeter 🔌 Amp Continuity Ohm Hz, Live Check V-Alert Voltage Tester with Back Clip by James Maruffo

This is a very worthy clamp meter for the DIY and hobbyist. Its accuracy exceeds my expectations for such an inexpensive measuring device. This cheap meter won't replace a professional meter like the Fluke, but for everyday use at home, does it really matter if the reading is 11.4V or 11.3V? What I like about this meter is its 1mA resolution. for DC amplifier measurements with clamp. For comparison, I also have an Extech 380942 clamp meter that I bought 17 years ago for about $400. Extech still sells for $400. The $400 Extech has higher accuracy specifications than the $50 BSIDE ACM91, but the differences are small. I happened to check several DC and AC readings with clamps at low currents (e.g. around 25mA DC, 130mA DC, 330mA DC). and 160 mA AC). The readings from the Extech 380942 and ACM91 clamps were essentially the same and differed by no more than 1 or 2 mA. The ACM91 was stable at low DC clamp levels and drifted much less than the Extech. Some reviewers of the cavemen said they never bothered to read the instruction manual and then blamed the gauge for operator error. Some of them didn't connect the test leads properly. What was not clear to one reviewer is that terminal readings only work with one phase (i.e. one wire) at a time. The most important thing about DC clamp meters is that they use a hall effect sensor to detect DC current. The manual specifically states that the user must hold the zero button for 2 seconds to zero the reading before taking the reading from the DC amplifier with the clamp. Some users failed to zero the meter and got completely wrong DC amp readings and then blamed the meter. I will add another detail not mentioned in the manual to improve the accuracy of the DC amplifier when using clamps. After zeroing the DC current meter, hold the meter in the same orientation that you are taking the measurement. Do not tilt, twist or rotate. Otherwise, reorienting the meter due to different magnetic field strengths on the ground may result in incorrect readings if the meter is oriented differently after zeroing. The main disadvantage is that the counter screen is very difficult to read. It has a curved protective lens and it is almost impossible to block reflected light due to the curvature of the lens. A flat surface would work much better to minimize reflections.
