Question:

Use multimeter and DC power supply should pay attention to what matters

Use multimeter and DC power supply should pay attention to what matters

Answer:

The AC voltage into a stable DC power output using the power supply equipment. DC power supply: Turn on the machine: ① first turn the voltage adjustment knob to the minimum position (usually counterclockwise to reduce), then turn the steady flow knob to the minimum position. ② Connect the power cord of the DC power supply to the AC outlet, and turn on the DC power supply switch. Regulator; ③ rotating steady flow knob on the steady flow value for the appropriate adjustment. ④ rotation regulator knob according to the need to adjust the voltage, the voltage value is generally not too much. Shutdown: ⑤ After the first test to complete the regulator, steady flow knob to the minimum position, and then turn off the power switch, and finally split the circuit used to connect the wire. Note: The switch can not be used as a circuit switch switch.

Multimeter is worth noting that the resistance file can not be no measurement voltage, pay attention to range. DC power output can not be short-circuited

Multimeter use time to pay attention to gear. Used to detect the circuit is good or bad when using low blocking.
