can I place 250ma fuse instead of 200ma fuse in multimeter, affacts meter calibration?
I'll answer a question you did not ask 1st: "is it dangerous to use a different fuse in my meter than the one specified by the manufacturer?". The answer for that question is: YES! Always use the recommended fuse type. Other fuses might fail to supply protection against damage to your device or even worse they might fail in protecting the user!

As for calibration, I find it hard to believe it would affect anything.
