Hello Guys,
I just got my brand new SDM3055 delivered, I was so excited I set it up and hooked to my SIGLENT SPD3303X-E and started taking some DC voltage measurements.
I swear sometimes I hear a hissing, sometimes a crackling noise (like sparks) coming from the multimeter, mostly subdued by the fan noise. It is not consistent, happens occasionally.
Is it something I need to be worried about?
I am brand new to a bench multimeter, so do not know what to expect.
Thanks for your answer.
