在很多地区,最好不用make direct contact with current-carrying cables in order to measure current. When a clamp meter is used, you just need to clamp the line to be measured with the measuring clamp. The PCE-DC 9EV with its clamp diameter of 25 mm can also measure insulated cables with relatively large cross-sections.
In contrast to standard household appliances, which are supplied with a maximum of 16 amps from a safety socket, machines and vehicles powered by powerful electric motors require several hundred amps. The PCE-DC 9EV has a measurement range of one thousand amperes for both AC and DC. This makes it suitable for current measurements on electric vehicles and in the industrial sector.
For alternating current, the current clamp shows the true RMS value so that even non-sinusoidal signals are accurately evaluated. With the inrush function, even short-term load peaks that occur, for example, when motors start up, can be measured. The low-pass filter allows electromagnetic interference to be filtered out and, in addition, frequencies of up to four kilohertz can be measured. The display with backlight shows the measured value in large digits and also the abbreviation for the measured parameter and unit in small letters.
