CURRENT MEASURING PLIERS:DESCRIPTION AND SCOPE OF APPLICATION.
To measure the voltage parameters on a phase cable or wire, you need to get access to its bare part (terminal, section stripped of insulation) and the zero wire. In the case when it is necessary to find out the voltage of a solid wire in insulation located in the switchboard with a large number of contacts, current measuring pliers are used. How they work, what modes they support, and where they are used will be discussed below.

WHAT ARE CURRENT MEASURING PLIERS?
Current measuring pliers are a rectangular housing with an LCD display and a working part. The latter has a fixed side and an opening side. In the closed state, a ring is formed, where you want to place the cable. To do this, the user presses the lever / trigger, pushing the clip apart. Releasing it, the ring closes. Depending on the width of the opening of the working part, you can work with wires of different diameters (2-20 mm or 2-40 mm, etc.).
On the case there is a regulator of electric current parameters, which allows you to set the required mode for measurement. The cable in the winding, through the cores of which current flows, forms an electromagnetic field around itself. This is what ticks pick up, process characteristics, and display data on the screen. Direct contact with exposed wires is not required. There is also no need to connect a zero wire to determine the phase voltage. Measurements can be made on any part of the cable, and not just near the terminals, automatic machine, connectors.Two-pole voltage indicator
