remote programming by external resistance

I am working with a high voltage power supply.
up to 200V.

the unit had to go out for calibration. it had an external resistor between the current amplifier and the - shunt pins. I FORGOT TO WRITE DOWN THE RESISTOR VALUE SO NOW IT CAME BACK WITHOUT ONE.

I am testing a UUT shall switch voltage and current consistent with high power of 150V peak-peak and 220A peak-peak current. The test fixture will deliver 180V and 240A peak-peak to the UUT.

would it be R = (100 * 220)/240 ?
R= 92 ohm?

I got this equation from the power supply manual.

Please verify if I am doing this right.
Thanks
