The battery tester is a multimeter with a multitude of different functions. With the battery tester, current measurements up to 200 A AC can be carried out without contact. This current range from the battery tester already covers a large range of current measurements. Thanks to the contactless current measurements from the battery tester, measurements can be taken during operation. This means that no measurement preparations have to be made with the battery tester, since measurements can be taken directly on the line to be measured.
Another contactless feature of the battery tester is the NCV (Not Connected Voltage) measurement. With this measurement, the battery tester can indicate whether there is voltage on a line. Here, too, the battery tester does not have to be prepared for measurements during operation. These two properties of the battery tester reduce the risk of injury from an electric shock.
Other useful functions of the battery tester are resistance measurement and continuity testing. The battery tester's continuity test can be used, for example, to determine whether a relay in a switch box is fully closed. Thanks to the fast measuring frequency of the battery tester, any current fluctuations can be determined. This makes the battery tester an indispensable tool for every electrician.
