Features: Night eye lamp with lighting. Circuit on-off test. Special attention: Measuring AC voltage can not exceed 250V. Press the "inductive break point test" button, the charged symbol is the phase line, if there is a break point in the live circuit, move the test pen, the point where the charged symbol disappears is the break point Scope of application: suitable for detecting 12-250V AC and DC current and simply detecting 0 line, phase line and break point of ac current, as well as non-live conductor and on-off . Simple operation, safe and reliable to use. Specification: Condition: Brand New Material: Chrome vanadium alloy steel / ABS insulating plastic Optional color: Yellow / Red Battery model: 3PCS AG10 (1.5V) (Not included) Scope of application: suitable for detecting 12-250V AC and DC current and simply detecting zero line, phase line and break point of ac current, as well as non-live conductor and on-off Operation: Circuit on-off test: Press the "inductive break point test" button, the charged symbol is the phase line, if there is a break point in the live circuit, move the test pen, the point where the charged symbol disappears is the break point Package List: 1 * Test Pencil Notice: 1. Measuring AC voltage can not exceed 250V 2. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. .
