I'm trying to use XY mode with CH 1, 2 input. CH 1 scale shows Volt, but CH 2 scale shows Ampere. Shouldn't both CH scales show Volt? How to change CH 2 scale to Volt? If we assume the Ampere scale is correct, then the wave amplitude is 10 times off. (both probes are 1X.)

Hello,

It looks like your Ch 2 has been setup to measure current. To change this back to voltage, push the Ch 2 menu button and select Probe Setup. Use the multipurpose knob to hover over Measure Current and push the knob to toggle back to No. This should change the scale back to volts and fix the 10x amplitude problem. When the scope is setup to measure current, it auto sets the volts to amps conversion as 10A/V.
