Help working out the calculation for SAK215 pulse shapper IC

Hello everyone

I’m getting confused trying to work out the calculations I need for the circuit on the datasheet.

I want to work out the adjustment resistor needed for pin 6.

The milliamps at full scale is 1.3 and the moving coil resistance is 1K. The circuit is working from a 12v supply.

Any input would be appreciated.

Thank You
