My name is Carlos and I would like to ask you something.
I have just bought a new oscilloscope HPS40.
I work as an electronic technician repairing TV, monitors, and audio equipment. The mayor voltages are found on the TV sets. And I would like to be sure about the maximum voltage that this oscilloscope can handle at his input voltage. This question is for I do not understand quite well the manual.
Having the probe and the oscilloscope settled to X10, may I measure the following values on a TV set?
The main voltage 220 on the line?
Would you be more specific with the answer? What I mean is which are the maximum values that can be safely being measure?
The same question is for the DC voltages: what is the maximum value?
I do not understand the 200v peak-peak. Does it mean that you cannot have any measure higher them 200volts without the x10?
Thank you very much for your answer. I am learning how to work with it in order to start this Monday 2.
You are correct that the 200V pk-pk limit for AC input means you can only measure 200V AC without the X10 probe. You also need to keep in mind that the 220VAC mains power is 312V pk-pk.
On DC the maximum input with a 1:1 probe is 100V. The input limit is still 100V when using the x10 probe, however the probe divides the source voltage by 10 before applying it to the 'scope input–in other words, all the 'scope input ever “sees” is the source voltage / 10.
