The Ermenrich Ping MK10 lock pick is a portable measuring device that does not require breaking the circuit to measure the current, thus enabling safe work on electrical networks and equipment. The digital lock pick is essential when the power cannot be turned off and is easy to use when measurements need to be made in hard-to-reach places.

The device combines the following functions: voltmeter (measurement of direct and alternating voltage), ammeter (measurement of alternating current) and ohmmeter (measurement of resistance). Calculations are performed using the True RMS function, so the measurement accuracy of variable quantities is high. Additional functions of the model include checking circuit continuity and fault testing of diodes.

The measurement results and operating parameters of the device are displayed on the built-in screen. The backlight of the screen makes it easier to work even in low light conditions or complete darkness. The data retention function is useful in situations where it is not possible to immediately read the measured values ​​from the device. When activated, the values ​​are "frozen" on the screen, so they can be accessed later.

Two standard batteries are required to operate the device. The automatic switch-off function helps to save energy. If the batteries are low, a notification will appear indicating that they need to be replaced.

Main characteristics:

- Measurement of alternating current without breaking the circuit
- The rectification is an alternating voltage, or determination of resistance
- Diagnosing malfunctions of diodes (open and short circuits), checking circuits to identify short and open circuits
- Data retention function for freezing the measured values ​​on the screen, saving the maximum value
- True RMS high precision calculation of variables
- Battery operated, automatic switch-off function
