Dear Sir/Madam,
I have a Digital Multimeter UNI-T UT890C+, from the manual, there is an instruction
"The red test lead can also be used to check whether or not F1 or F2 has been blown. If the “mAμA” jack is tested to be 1MΩ and
“A” jack is tested to be 0Ω, then the fuse acts good. If the unit displays “OL”, then the fuse has been blown."
I don't understand how to test whether the F1 or F2 fuse is blown, does anyone get the meaning?
Best regards,
Kelvin.
