Eico 235 VTVM
#1

I have gone through the whole meter and replaced all parts needed. The meter works but when referring to the manual it states to adjust R23 to get a zero meter if you don’t when selecting the function switch. I tested R23 it reads around 11K but when testing to adjust the zero needle it does nothing.Also thinking of a battery eliminator circuit to replace the D cell battery.
