The Ermenrich Zing TC33 digital multimeter is a True RMS measuring device that does not take up much space in an electrician's chest and is perfectly suited for the diagnosis and maintenance of electrical networks and electrical equipment. Thanks to the wide range of functions, the multimeter is a great tool for professional tasks. Even laymen can use it, as it has intelligent functions that make it easier to operate the device.

Its large color screen has large numbers and a graphic scale. It measures voltage, current, resistance, frequency, temperature, capacitance and duty cycle. The measurement limit is automatically selected. Additional modes include open test (finding open and short circuits), diode test, phase detection and locating hidden cables. The device is extremely accurate.

In the hold mode, the read values ​​are "frozen" on the screen. This feature is ideal for situations where the screen cannot be read immediately so you can view it later. The device has a built-in flashlight, which is very useful in the dark. The multimeter is powered by a rechargeable battery, so there is no need to replace the batteries regularly.

Main characteristics:

- Large color screen with graphic scale and numbers
- True RMS calculations that improve the accuracy of measuring non-sinusoidal signals
- 7 measurement functions: voltage measurement, current measurement, resistance measurement, capacity measurement, frequency measurement, thermocouple detection, duty cycle measurement
- Smart mode (automatic signal recognition)
- Additional operating modes: diode test for open and short circuits, break test, non-contact high voltage detection, phase detection
- It is powered by a rechargeable battery; it has an automatic switch-off function if the device is not used for a long time
