Hi Guys, Well i have been working on this VTVM all day. I recap it and I have a problem with the DC calibrate. I put the meter on 1.5 volts and DC+ and the meter slowly goes to full scale . I can not bring it back with the zero ajustment. If i put the range to 50 volts or better i can ajust it with no problem. Any ideas? Rick VE7RiK
