Induction digital display stylus use method details
I. Button description:
A key "DIRECT": for the direct measurement key (away from the LCD screen), that is, with the electric pen metal front end (referred to as the batch head) directly contact the line, please press this button;
B button "INDUCTANCE": for induction / breakpoint measurement key (closer to the LCD screen), that is, with the batch head induction (note that the induction, rather than direct contact) line, please press this button.
Regardless of how the text is printed on the pen, in general, the one farther away from the LCD is the Direct Measurement key, and the one closer to the LCD is the Sense/Breakpoint Measurement key. If this is not the layout, it indicates a cottage or poor quality products, for your safety, do not recommend buying.
Second, direct detection.
1. Touch the DIRECT key, the metal front end of the stylus is directly in contact with the object to be detected: 1.1 The last digit is the number of the measured object, the metal front end of the stylus is directly in contact with the object to be detected.
1.1 The last figure for the measured voltage value (the stylus is divided into 12V, 36V, 55V, 110V, 220V five voltage values, usually ≤ 36V is not life-threatening);
1.2 Not up to 70% of the display value of the high segment, the display of the low segment value;
1.3. when measuring DC power that is not to ground, the hand should touch the other pole (such as positive or negative pole).
2. When the pen is in direct contact with the fire wire, the indicator will light up immediately whether or not the hand has touched either of the measurement keys:
2.1 When the hand does not touch any of the measurement keys, the indicator lights up and displays 12V, which is not allowed;
2.2 When the hand touches the inductive/breakpoint measurement key, the indicator lights up and shows 110V, which is not allowed;
2.3 When the hand touches the direct measurement key, the indicator lights up and displays 220V, which is an accurate value;
2.4 To summarize, if the indicator lights up without the hand touching any of the measurement keys, it indicates the presence of 220V on the AC line!
3. when the hand touches the direct measurement key, when the pen is in direct contact with the human body, fire wire, zero wire, ground wire, metal and other conductive objects, the indicator may light up, then the actual voltage is based on the readings, if there is no reading indicates that there is no voltage. 4. when the hand touches the inductive / disconnecting key, the indicator may light up, if there is no reading indicates that there is no voltage.
4. When the hand touches the inductive/breakpoint measurement key, there are two situations when the pen directly touches the detected object:
4.1 The indicator light is on and 110V is displayed, which indicates that there is an alternating current of 220V on the firewire, remember to keep in mind!
4.2 The indicator does not light up, but there is a "high voltage symbol", please refer to the "three, indirect detection" in the 1, 2 points.
Indirect detection (also known as inductive detection):
1. Induction detection: Touch the induction/breakpoint measurement (INDUCTANCE) key, the metal front end of the stylus is close to (note that it is close to, rather than in direct contact with) the object to be detected, if the display appears "high-voltage symbols", it means that the object to be detected with the internal alternating current.
2. Breakpoint detection: Measurement of broken wires, touch the INDUCTANCE key, the metal front end of the stylus is close to (note that it is close to, not directly in contact with) the wire, or direct contact with the insulation of the wire, if the "high-voltage symbol" disappears, it is the breakpoint here.
3. The use of this function can easily distinguish between zero and phase lines (to increase the distance between the lines when measuring side-by-side lines). Detection of microwave radiation and leakage.
Fourth, notes:
1. The button does not need to be pressed hard.
2. The two measurement keys should not be touched at the same time when testing, otherwise it will affect the sensitivity and test results.
