yes, of course it is. one way is using a curve tracer.
you use an ohm meter
The Diode Check setting on a DVOM is a special ohms setting that presents enough voltage to the tested device to conduct, if it were a diode. Old style VOM's did not have this problem, because they usually used a battery greater than 0.7 volts to run the ohm's scale. Modern DVOM's, however, can use very small voltages to measure ohms, and that would not cause a diode to conduct. The Diode Check setting fixes this limitation.
The purpose of a diode is to allow electric current to pass in one direction while blocking electric current in the opposite direction. It is for this reason that diode is usually referred as the check valve.
A diode is a one way check valve basically. it will let current pass one way but not the other.
The diode must be isolated from any parallel current paths to test. check resistance both directions through diode. readings should show an open (or very high resistance) one direction and a short (or very low resistance) the other direction. Usually, a failed diode will show an open both directions. Set the multimeter to check resistance, attach each meter lead to opposite leads on diode, note reading, then swap meter leads and compare readings.
The cathode of a diode is usually indicated with a band. In the absence of the band, consult the datasheet. Alternatively, use an ohmmeter that generates more than 0.7 volts at low current (a diode checker) and check conductance. The diode will conduct when the anode is more positive than the cathode.

The best way is to visit their website and check if your area is serviceable or not. If yes, you can book an appointment from the website.
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
yes, diode can be used as rectifier diode to convert ac to dc
The read type diode are called impatt diode
