I made one electrode checking experiment. I took two Saturated calomel electrode filling solution is saturated KCl and the electrolyte is saturated KCl. I checked the potential with Multimeter It came Zero.
After that I coupled Saturated Calomel electrode with Sat Ag/Agcl is used with same electrolyte
I got 44 millivolt from Multimeter .
Potential of saturated Ag/AgCl is 0.197
Potential of saturated Calomel electrode is 0.241
potential difference is 44mV
0.197+0.044=0.241
I thought the electrode is Perfect. Is it correct?
