This digital pen has a flashlight function and a large backlit screen, allowing you to read values clearly even in dark places. Hold key One key to save data, easy to read data. This Hz tester supports NCV non-contact voltage detection, which can distinguish between the neutral line and the live line to avoid the risk of electric shock. This digital multimeter pen can automatically determine measurement parameters and support automatic range, which can be used for AC and DC voltage/resistance measurement/continuity test/frequency measurement/diode measurement. This digital multimeter has an automatic shutdown function, which will automatically shut down within 15 minutes without operation. Press any key to exit the standby mode. You can also hold down the "SELECT" key to disable automatic shutdown. Function: AC/DC voltage measurement Resistance/capacitance measurement Non-contact voltage detection Data hold/Hz Induction detection On-off buzzer detection Zero fire detection Audible alarm Automatic shut-down Bright backlit display Specifications: Material: ABS Size: 225.4*46.3*8.7mm AC and DC voltage: 0-600V Resistance: 0-40M Capacitance: 0-4mF Hertz: 0-4MHz Maximum value: 4000 Battery: 2 x AAA Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
