Features: brand new and high quality With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. At the same for time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and nu ll wire are detected. After testing three phase lines,the screen displays the results,"R"shows positive phase sequence, "L"shows negative phase sequence, otherwise it`s phase loss. Bright LED flashlight for work in dim ares; Low-Power-Indicator when battery voltage is below 2.5V; Automatic Power Off after 3 minutes without operation or signal detection. Pocket-sized, pen hook allows you to carry it in your shirt pocket. There are 2 types, HY118A and HY118B. Specifications: Material: ABS Length: 170mm/ 6.69 in Resistance measurement range: 600/6K / 60K / 600K /6M/60M Operation mode: Manual Measuring range of inductance: 1Hz-10mhz Note: Please allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.
