Features:
1.LCD high-definition display is more clear: in the dark environment can clearly see the test display value of the large screen display readings at a glance
2. Quickly identify the detection of AC voltage value: the tip of the pen contact test AC (leakage) voltage quickly identify the conductor (leakage) voltage high and low
3. Route breakpoint detection: In NCV non-contact voltage detection mode, single-stranded wire charged along the road to rule out the location of the breakpoints.
4. Intelligent zero-fire line judgment: choose LIVE zero-fire line distinction function, insert the pen needle into the hole for identification without the traditional contact identification, power measurement is safer.
5. Voltage leakage detection: the tip of the pen contact test AC (leakage) voltage, and quickly identify the conductor (leakage) voltage high and low.
