Re: 577 AC collector supply not reading zero on display

DW
 

Max peak volts 6.5
Series resistors 0.12
Horzi V Division 50mV
Vert I Division 0.2mA
Collector voltage 0V
100 ohm Resistor across Collector Emitter

With collector set to AC and switch set to neutral a solid horizontal line appears across 2 divisions.

With the selector switch set to left a 50 deg vertical line appears approximately 3 divisions vertically

In any position but AC for the collector polarity there is a displayed dot.

It appears there is a small residual power flowing through the collector supply when set to AC, about 0.5mA of current
