It is they who gave Fluke the greatest trust and the best word of mouth. The Fluke brand is highly regarded for its portability, robustness, safety, ease of use, and rigorous quality standards, and is a leader in the field.
1. First, introduce the AC voltage gear, turn the switch to V~, the pen is divided into red and black, the red pen is generally connected to the positive (+), and the black pen is usually connected to the negative (-) or ground (GND), AC There is no positive or negative, like the mains 220V is AC, two pens can be inserted into the power socket hole to display the voltage value. Note that the red and black pens can not be shorted, otherwise, it will cause short circuit trip, the hand can not touch the metal of the test pen Partly to avoid personal safety
2. The DC voltage position is introduced below. The DC voltage is the voltage rectified by the electronic components. The common DC voltage is +5V, +12V, +24V, -12V, etc. When measuring, switch the switch to V- Where the red pen is connected to the measuring point, the black pen is grounded (GND), and the current DC voltage is displayed on the screen.
3. Next, introduce the ohm gear position. This gear position is the measuring resistance. Turn the rotary switch to Ω. The red and black test leads are connected to the metal parts at both ends of the resistor. The screen can display the resistance value. This multimeter is an adaptive measurement range. No need to set the range
4. Next, introduce the diode gear position. This gear position is whether the diode of the measuring circuit is burnt out. The rotary switch is still in the Ω gear position. At this time, press the yellow button to switch to the diode gear position. The diode has a single-pass nature. , red pen connected + pole, black pen connected - pole, in conduction, red pen connected - pole, black pen connected + pole, in a non-conducting state
5, the following describes the buzzer file, mainly to measure whether the circuit is short circuit or open circuit, the rotary switch is still in the Ω gear position, press the yellow button twice, you can switch to the buzzer file, the measurement method is very simple, red pen Connect the A end of the wire, the black end of the black pen to the B end, the buzzer sounds, the line is clear, the buzzer does not ring, and the line is open, meaning that A and B are directly disconnected.
6. The following describes the capacitor gear position. This gear position is used to measure the capacitance value. Turn the rotary switch to the || file. Under normal circumstances, the red meter pen is connected to the + pole, and the black meter pen is connected to the pole. The value displayed on the screen is the capacitance value. And the capacitor is marked with a similar value
7. Finally, introduce the current gear position, turn the switch to the A file. Measurement method: insert the red test pen plug into the “A†hole, and connect the red test pen and the black test pen to the circuit respectively to display the current value in the circuit. In general, this gear is rarely used.
Fluke's six and a half meters 8846 is good, the handheld table FLUKE289 is also very good, this is the original table, there are also domestic 115c, 116C, 117C and so on.
Xiaobian recommended the use of Fluke 115c and 117c, then follow Xiaobian to understand the difference between Fluke 115c and 117c?
The difference between Fluke 115c and 117cThe difference between Fluke 115c and 117c is compared by the three choices of Fluke 115c and Fluke 117c, which are the following three points:
1. VoltAlertTM technology for non-contact voltage detection
2, AutoVolt automatic DC / AC voltage selection
3, LoZ function: low input impedance, can prevent false readings caused by false voltage
The above three items are more than FLUKE115C. See if you think it is practical and not practical.
