Hello, today I'd like to show you how to use a current clamp meter. We will use the popular Unity UT 202A and the Unity UT 203 models to demonstrate. First, let's talk about what a clamp meter actually is. The clamp meter is a meter device capable of measuring current without direct contact to that current. This is one of the main advantages of a clamp meter compared to traditional ammeters and multimeters. You don't need to break the circuit to conduct measurements; you can actually conduct measurements of the line under voltage as well as measuring high currents. Operational safety is one more advantage; you are able to measure the current of an insulated conductor. Measuring current with these meters is really simple. You just switch to the required measuring range of current. In our case, it's 600 amps. Press the trigger to open up the clamp's jaws and place the conductor you want to test inside and close the clamp. The display then shows the measurement results. The main element of a clamp meter is the current sensor. There are two types of sensors used. One type is a current transformer and the other is a Hall sensor. Depending on the sensor used, the meter may measure either alternating current or direct and alternating current. Here we have a clamp meter with a current transformer. In this meter, inside the plastic housing, there is a magnetic core. If you open up the clamp, you can see part of it. The conductor that measures the current acts as the primary winding and the secondary winding is inside the plastic housing. We aren't able to see that. The main advantage of this type of design is having a low price and simplicity. The drawback is that it's a transformer, so...
