Default Analogue moving coil meter range extension?

The simple answer is put a 62K 5% resistor in series with the meter.
It's read about 4% low (240 uA instead of 250 uA.)

You wanna get a little closer? put a 100K and a 150K in parallel.
Wanna make it adjustable? Put a 100K trimpot in parallel with a 180K
resistor.

This ain't rocket science folks.


It's also plainly noncompliant with the project requirements.
