Re: Help - trying to understand how to use 2204A

Or perhaps to put the question a bit differently:
What Picoscope settings would you recommend to measure dirty electricity on a 60 Hz house circuit?

I haven't used an oscilloscope since tech school, back in 1969. They seemed easy back then. This is a very powerful unit. I am trying to measure dirty electricity at my home in Edmonton Alberta Canada (60 Hz). I made a voltage divider circuit to reduce the input voltage to less than 20 VAC so it wou...

Hi again from Lawrence (I just posted first post)

This is an attachment to my earlier intro post. I have attached a file from attempting to measure my house voltage (120 VAC, as I am in Canada) I am using 20 VAC on the software, and have the probes set to 10x, yet it only shows less that 4 volts - it should be around 12 VAC. When I first connect th...

How to measure voltages higher than 20 V PTP?

Hi, my name is Lawrence and I am retired, have worked in Electrical all my life, but have not used an oscillosope in approx 50 years (since being at Technical school). I bought the Picoscope 2204a to measure dirty electricity at home. Q1: how does one measure voltages higher than the 20 V PTP marked...
