Hi,
Has anyone used pgm03a as a scope to measure negative voltages? I know that a voltage divider would map a higher voltage to 0-5 v, but can a negative voltage be measured? Any (simple) ideas? Thanks.

Hello, Bo.
You could use a circuit like a voltage divider. Instead of connecting it to ground, you would connect it to 5V. With the right resistor values, it will map negative voltages to the 0-5V range required for the SLO-scope.
