What is the purpose of a digital pen?
(1) Button Description.
(A) DIRECT, direct measurement button (far away from the LCD screen), that is, when you use the pen to contact the line directly, please press this button.
(B) INDUCTANCE, inductive measurement button (closer to the LCD screen), i.e., press this button when you touch the line with the tip of the pen inductively.
Note: Regardless of how the words are printed on the pen, please remember that the one farther away from the LCD screen is the direct measurement key; the one closer to the LCD is the inductive key.
button.
(2) digital stylus is suitable for direct detection of 12 ~ 250 V AC and DC and indirect detection of AC zero line, phase line and breakpoints. It can also measure the on-off of uncharged conductors.
(3) direct detection.
① The last figure is the measured voltage value.
(2) When the display value is less than 70% of the high break value, the low break value will be displayed.
③ When measuring DC, the other pole should be touched by hand.
(4) Indirect detection: hold down the B key, the pen tip close to the power cord, if the power cord is charged, the digital pen display will show the high-voltage symbol on the display.
(5) Breakpoint detection: hold down the B key, move along the wire longitudinally, no display in the display window is the breakpoint.
