Can i use a multimeter to find out the frequency of AC power supply ? or is there any cheaper ones
I stay in a township which gives backup power supply and sometimes i am not sure if its AC or generator backup which is expensive , so someone mentioned i could measure frequency and find it out , now the question is how to measure frequency
