I have recently discovered that the mA range for my multimeter doesn't work, and before you ask: Yes I have checked the fuse and the fuse is fine
It has two settings, one for 200uA to 200mA and one for 10A (both DC)
Connecting up a circuit which should be drawing 100mA I get a 0.10 reading on the 10A DC range which looks all OK.
However on the 200mA range where I should get 100 I get nothing.
It's not just the meter isn't reading the current, the current doesn't appear to be flowing at all. A simple circuit with an LED lights up on the working 10A range but on the other ranges the LED doesn't light and the display shows nothing.
When I opened it up I noticed a strange component I don't recognise. It's soldered where the silkscreen shows a resistor symbol but I don't think it's a resistor.
I have attached photos... Its the thing marked "75S" which looks like a cross between a Tantalum and a Disc Ceramic
