Define to measure, with a multimeter.
The diode between C and E has a forward conduction, a reverse inversion, and a positive and negative connection between other pins, which can basically be considered good.
If you want to measure further, use a pointer multimeter or power supply to add a forward voltage to G and E, and C and E will be turned on at this time; Add a reverse cut-off voltage, and C and E can only measure the characteristics of the protection diode.

1 Dial The dial consists of a dial mark, a pointer and a mechanical zeroing nail, the measured value is read by the position of the scale mark pointed by the pointer, and the mechanical zeroing nail is located in the lower middle of the dial.
The MF50 multimeter has 8 tick marks. Counting from top to bottom, the first tick mark is the Euclidean tick that reads the resistance value when measuring the resistance. The second tick mark is a common tick mark for AC voltage and DC current readings.
The third tick mark is a special tick mark for measuring AC voltages below 10V. The fourth and fifth tick marks are dedicated to measuring the magnification of the transistor.
2 Transfer switch The function of the transfer switch is to select the measurement item and range.
1) DC voltage: 10V, 250V, 1000V, five ranges.
2) AC voltage: 10V, 50V, 250V, 1000V four range gears.
3) DC voltage has three common ranges of 25mA and 250mA, and 100ūa, two extended range ranges.
4) Resistor: There are five magnification gears of 1, 10, 100, 1k, 10k.
5) HFE is a dedicated gear for measuring the DC amplification of the transistor.
How the F16N50 is measured with a multimeter.
Hello! 1 Dial The dial is composed of a scale mark, a pointer and a mechanical zeroing pin, the measured value is read by the position of the pointer pointing to the marker, and the mechanical zeroing nail is located in the middle of the lower part of the watch.
The MF50 multimeter has 8 tick marks. Counting from top to bottom, the first tick mark is the Euclidean tick that reads the resistance dissipation and appreciation when measuring the resistance. The second ticker is a common gauge for AC voltage and DC current readings.
The third tick mark is a special tick mark for measuring AC voltages below 10V. The fourth and fifth tick marks are dedicated to measuring the magnification of the transistor.
2 Transfer switch The function of the transfer switch is to select the measurement item and range.

2) AC voltage: 10V, 50V, 250V, 1000V four range gears.
3) The DC voltage is next to the search for two common gears of 25 mA and 250 mA, and 100 Ūa, two extended Sun life ranges. Sleepy.
4) Resistor: There are five magnification gears of 1, 10, 100, 1k, 10k.
5) HFE is a dedicated gear for measuring the DC amplification of the transistor.
I hope mine can help you, I wish you good health and all the best, I wish you every day thereafter, your eyes are sunny, your smile is open, thank you!
The bad part is the transformer, the transformer in the circuit can be used for the audio output transformer for transistor radio, the secondary is used as the primary of the step-up transformer, the tap in the middle of the primary is not used, and the taps at both ends are used as the secondary of the step-up transformer. If you can't find a suitable transformer, you can also use the silicon steel sheet of the radio output transformer to make your own, and use a high-strength enameled wire with a diameter of 0 25mm for 110 turns for the primary stage, and a high-strength enameled wire with a diameter of 0 21mm for 520 turns for the secondary. A layer of insulating paper should be added between the primary stages, and attention should be paid to the eponymous end of the primary stage coil. >>>More
Looking for faults should be first outside and then inside, easy first and then difficult, and the whole should be broken into zero, and the key breakthroughs should be made. The methods can be roughly divided into the following types:1 >>>More
Turn the digital multimeter to the current gear, take the red and black stylus to the two sides of the contact switch under the float, there is a current display to prove that it is energized, and there is no current display to the line is faulty.
It depends on whether you use digital or analog, anyway, it is adjusted to the amount you want to measure, remember to connect the black watch pen to the negative pole of the power supply when measuring, and the red watch pen to the negative pole of the power supply. >>>More
MF47 multimeter measures and measures DC voltage: the maximum allowable measurement voltage of its ordinary board surface is 1000V. Another special terminal with a measuring voltage of up to 2500V (not recommended for general operators). >>>More
