Philco Model 048 all purpose set tester
#3

Bill,

The 048 Tester uses four battery voltages. The VOM section uses a 4.5 volt for the ohms function (isolated from the other cells).
The Sig gen section uses two voltages; 1.5 and 22.5. The two voltages are in "series" in the battery. the (+) of the 1.5 cell is common to the (-) of the 22.5 and brought out to a terminal (3 terminals). Can't clearly see the socket on the top of your battery pic.
