The SCR's gate electrode is used to turn the SCR on, i.e. fire it.
You can check if it is shorted, but without coordinating the gate and anode voltages with the cathode, you cannot test a thyrister (SCR) with a multimeter. Check it out of circuit for shorts, then check the circuit, then test it in operation. Anything more advanced will require an oscilloscope.
thyristor can be scr or triac scr is strictly dc a triac is back to back scr's with a common gate two scr's back to back can be gated independently scrs cost less than triacs an scr can be combined with a full wave bridge to make an equivalent to a triac but this gives an additional 1.5V forward voltage drop
An SCR has three legs. The anode, cathode, and gate. The control voltage sent to the gate will allow the SCR to conduct.
Scr looks like a regulator IC. So keep the scr in such a way that its name should face us. then from left it will KAG.
because it is gcr not scr

Beware using ground clips for high speed measurements.Beware of oscilloscope bandwidth limitations.Ensure the correct triggering.Use the right oscilloscope probe.Remember to calibrate the oscilloscope probe.Beware using ground clips for high speed measurements.Beware of oscilloscope bandwidth limitations.Ensure the correct triggering.Use the right oscilloscope probe.Remember to calibrate the oscilloscope probe.

Karl Ferdinand Braun invented the Oscilloscope in 1897
Audio Frequency Oscilloscope and Cathode Ray Oscilloscope

Oscilloscope probes are used as part of an Oscilloscope. These are the pieces that connect to your circuit in which you would like to measure its sine waves.
The resistance of an ideal oscilloscope probe is infinity.
A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
