I just got my DHO804 and i see no plastic cap on the input probe as how it should be in the attached picture below. Should i be worried? .... I bought it in India, does it have to do something with that?
Worried about what exactly?
How did your unit arrive, was it wrapped & sealed - all for your protection.. you should incl. that fundamental info, if people should have any aspect of guessing on your behalf if there is something to be worried about..
And why should India as a purchase location be synonymous with missing plastic caps?
I don't have a DHOxxx, but got another product from Rigol a month back (sig gen) using the same form factor... it got 6xBNC sockets and none of those had plastic/silicone caps.
Units fresh out the own - will usually have an official Rigol tear-sticker, alongside thin plastic film...exampled on my unit below, though quite an early unit snxxx000000013
