This is your schematic. It says under your galvanometer: 400uA, 250 Ohm.
It means that
1) 400uA will fully deflect your spindle.
2) 400uA will develop 0.1V dropout across that spindle coil.
3) this resistance is in series with any other resistance that is a part of your switched divider. Simply speaking, if there is nothing else in parallel or in series with this galvanometer, you will need 25kOhm resistor in series to fully deflect the needle at 10V.
