If your multimeter has a transistor check (hfe), then place the Collector,Base& Emitter in the CBE port of multimeter.
Turn the shaft to Diode mode.
If the value is zero,skip that transistor.
You can use the forward resistance of each junction, using the ohms range or diode check function.
Put the leads on the Base and Emitter, then reverse the leads. You should get about 600Ohms forward bias and open circuit (infinity) reverse bias.
Do the same between the Base and Collector. You should get the same results.
Finally put the leads between the Collector and Emitter. You should get open circuit both ways around.
Be aware that some high power transistors have a diode across the Emitter and Collector.
These tests will just be a basic 'go - no go' test. It may pass this test and yet still not perform fully.
You can see obvious faults, like a dead short both ways on each junction or across the Emitter to Collector.

How we check Bipolar junction transistor with digital multimeter?
By testing the C B E terminals.
How do you check transistor by multimeter?
a BJT may be tested as two diodes using the ohms scale. a FET cannot be tested with just a multimeter.
How do you check field-effect transistor using analoge multitester?
There is no simple way to test FETs with either analog or digital multimeters. Bipolar transistors can be tested to see if their junctions are OK but they can also have failures that cannot be detected with a multimeter.
Is an electronic multimeter a digital or analog?
digital
What electrical characteristic does a digital multimeter measure?
A: Depends on the meter it measure ohms, voltage, current. some may test for transistor beta health of battery and then some
What is TTl in digital electronics?
transistor transistor logic
Who has a wide range digital or analog multimeter?
The analog multimeter has a wider range.
What to do if the digital multimeter is faulty?

When testing for current draw your digital multimeter should be set on?
When testing the current draw your digital multimeter should be set on the current.
How do you check voltage in an exposed wire?
To check the voltage in an exposed wire, you can use a digital multimeter in voltage measurement mode. Ensure the wire is not connected to any power source, then carefully touch the multimeter probes to the exposed wire's metal contacts. The multimeter will display the voltage present in the wire.
How many volts takes multimeter?
In Digital multimeter we use 9V Dc battery.
What is the Application of a digital volmeter?
A digital voltmeter is used in a multimeter to check the Voltage. It is also used in data acquisition on interfacing with computers and also include integral monitoring software.
