Dear Sir/Madam
Please kindly help to assist me for the following question.
I got a riveting machine, which has a counter on it.
The counter used is line seiki MCF-4X, with voltage of AC220V
https://www.lineseiki.com/products/electromagnetic/MCF/
It is found sometimes the counter not responding.
I want to measure the two wires linked to the counter (to ensure the signal is normal).
Can I use oscilloscope to measure directly? I am worried about damage my oscilloscope. (not sure if it is earth grounded) Two wires power source (like two-prong electrical outlet?) can't be grounded, right?
or what I can do to double confirm?
If it can be measured directly, I need to measure it with counter connected, right?
Thank you in advance.
Best Regards
Simon
