Current measurement of in-vehicle electrical components

I bought it because I can measure direct current with reasonable price. It is very helpful to be able to measure DC current without disconnecting the circuit. Since it does not cut the circuit, we thought that we could prevent damage of equipment due to unnecessary human error mistake, we have purchased it. As it seems to drift during measurement, it seems that it is necessary to perform zero adjustment immediately before reading the numerical value.
It is mainly used for measurement of direct current.

I compared the measurement with a DC ammeter, but it was a measurement with almost no problem. Deep Cycle Battery Load Measure Deep Cycle It is convenient for load current measurement of batteries It is affordable so I bought it.
Although the model is C - 01U - M, the item received is C - 01U itself of company C, and it seems that there is no particular distinction. One year warranty was also attached. The storage case seems to be user-friendly as it is made of nylon fabric with a belt loop. Sampling is 2 times / sec, but it is fairly fast only 5-6 times / sec feeling only in the 6.000 A range that can be selected with the manual range. I confirmed by matching with other instruments and measured values, and since ACDC was within specification error, it is enough to use. I think whether it depends on the measurement environment, but there was not such thing that the fluctuation was large and the instruction could not be read. The sensitivity adjustment function can not adjust sensitivity. Depending on the detected voltage, it is judged to some extent by the bar graph display and beeping interval (gradually changing from continuous tone to continuous tone), but it is safer to think about extra degree. Although the main body is compact, it is good, but the battery is a button battery LR44 × 2 and battery life is 20 hours. 6.000 A range and backlight, when it is heavy use of electricity inspection is to make it even shorter. There is a little room in the storage case, so it is better to keep spare batteries in them. It is a pity that there is no hole to attach the strap to the main body. For both ACDC, 0.001 A resolution, you can get cheaper if you use Monotaro's system well. I think that it is quite a good product.
