My TDS2002C is not reading voltages correctly. When I get peak voltage levels, I only gets a hundredth of what I anticipate. For example, when I measure 800 volts, the unit only shows 8 volts. I'm not sure what's causing the problem because it this was working properly yesterday. Any ideas on what the issue may be?

Hello,

It sounds like a default setup may have cleared the 100x attenuation set for the channel. To reconfigure the channel to reflect the external attenuation do the following. Open the channel menu > probe menu > press attenuation until it shows 100x.
