      The 30 volts battery(batteries?) are to power the ohms function on high Meg ranges. I have an Analog Meter that was badged for the Bell Companies (telephone) many years ago, probably late 70’s or early 80’s vinjtage. I am sure it is either a Simpson product or Triplett, most likely Triplett.

      It uses two 15 volt “Mercury” batteries. I’ve “heard” that those batteries are “obsolete”. I believe I looked them up once and they were available buy very expensive. Some other kind of battery could probably be kludged in. I simply use the meter without them, as I virtually never use a meter for high Meg ranges. All functions work perfectly, I just don’t use the high ohms. I have plenty of other meters if I need that function.
