Connect the meter
across the 1 000 ohm resistor. The voltage displayed will be 1/1000 the
input, i.e. 200V in will put 200mV across the meter.

As far as current, you'll need a very low resistance, precision
resistor to put in series with your power supply and load. Scaling is
similar to above. E.g. You have a 0-200mV meter, and you want to
monitor 0-20A. So, we know we want 200mV out for 20A current, so:
.200
In what galaxy???
