Instructions for use of digital test pen
1. Button description:
(A key) DIRECT, direct measurement key (far away from the LCD screen), that is, when using the batch head to directly touch the line, please press this button;
(B key) INDUCTANCE, the induction measurement button (closer to the LCD screen), that is, when using the batch head to sense the contact line, please press this button.
Note: No matter how the electric pen is printed, please recognize that the one that is farther from the LCD screen is the direct measurement key; the one that is closer to the LCD is the sensor key!
2. This test pen is suitable for direct detection of 12-250v AC and DC current and indirect detection of AC zero line, phase line and breakpoint. It can also measure the continuity of non-energized conductors.
3. Direct detection
a. The last number is the measured voltage value;
b. When 70% of the high-break display value is not reached, the low-break value is displayed;
c. When measuring direct current, the other pole should be touched by hand;
4. Indirect detection: Press and hold the B key, and place the batch head close to the power cord. If the power cord is charged, the high voltage symbol will be displayed on the display of the digital display pen.
5. Breakpoint detection: Press and hold the B key and move longitudinally along the wire, the place where there is no display in the display window is the breakpoint;
