I found a fusable resistor that shows no reading in circut. Should show a reading?
Thanks Charles
Thanks Charles
Sounds like the fuse used in the current measuring mode. Measuring voltage in the current mode gets the fuse every time. Replace only with same type for continued protection. Usually a fast blow type. If the interior of the meter or the markings on the fuse are not present or readable the manual can be found online.

It is a 1k ohm fusible.....
1k ohm is a strange value for a fusible resistor. Are you sure that it is not a PTC (positive temperature coefficient) resistor? In many DMMs PTCs are used to protect the resistance measuring circuit from overloads when connected to live circuits.
When overloaded, the PTC heats up, and the resistance goes more than 100 times higher, thus limiting the current.

That's definitely a normal 1K resistor. MF probably stands for "metal film", which is commonly used in flameproof fusible resistors.Service manual says:: R1) Res., MF, 1K Fusible 2%
Let me guess, shipping was three times what the order was?
