Yes, you can use a multimeter (on the resistance scale) to test the resistor. If I remember correctly, it should be in the neighborhood of around 85 to 90Ω. An open circuit reading would indicate a bad resistor.

Yes, I suppose it could be measured with it still installed. You'll want to at least unplug the power & sender wires so the reading isn't influenced by the rest of the circuit. And be aware that the calibration resistor is connected in parallel with one of the meter movement's internal coils. So if the resistor is good and making good contact, the resistance you read on the meter will be of the two in parallel. I think the coil resistance is pretty close to that of the resistor so the two in parallel will be about half.
