The Ermenrich Zing TC21 digital multimeter is a multifunctional device for testing and measuring the parameters of electrical networks of various complexity. Designed specifically for professional use, it meets the needs of electricians, engineers and maintenance technicians. In addition to basic voltage measurement, current measurement and resistance measurement functions, it can measure frequency, capacity, duty cycle and temperature. The multimeter is a True RMS device, that is, the calculations are based on the True RMS method, which significantly increases the accuracy of the readings.

You can manually select the measurement limit value and operating mode with the rotary switch. The detected values ​​are displayed on the backlit monochrome screen. The multimeter has a flashlight, so you can work comfortably in the dark or in low light conditions. Additional functions enable full network or equipment diagnostics: locating open or short-circuited circuits, hidden wires or other objects with dangerous voltage, phase detection, diode test and battery charge level check. The multimeter also has a hold function and records minimum and maximum values.

It works with traditional elements. The automatic shutdown function helps to save energy if the device is not used for a long time.
