The Ermenrich Zing TC40 is a pocket-sized multimeter for testing electrical networks and measuring the parameters of many electrical signals. The color screen is high-contrast and has large numbers and a graphic scale. The device provides high-precision measurements based on the True RMS method and is powered by a rechargeable battery. The device is suitable for both professional and home use.

The Ermenrich Zing TC40 digital multimeter measures the following characteristics: current, voltage, resistance, frequency, capacitance. It also has a duty cycle and temperature measurement function. Diagnostic functions include diode test, open test, phase detection and non-contact high voltage (NCV) detection. With the hold function, you can keep the read values ​​on the screen.

One of the most important features of the instrument is that it can perform not only absolute but also relative (REL) measurements. The reference point can be set by pressing a separate button, the multimeter then calculates the difference between the measured value and the reference point during the measurements. The Smart function: In Smart mode, the device automatically detects the type of signal and calculates the voltage and resistance. Tear testing can also be performed with this function.

Main characteristics:

- Combines 7 measuring device functions: current measurement, voltage measurement, resistance measurement, frequency measurement, capacitance measurement, duty cycle measurement and thermocouple detection
- Tests cables for short and open circuits, tests diodes, detects phase, detects high voltage without contact
- Smart mode for automatic signal detection and measurement: resistance, voltage and break test
- REL function (setting a reference point for measuring relative quantities)
- Color screen with digits and graphic scale, operation from a rechargeable battery
