AMC1303M0510: Replace from AMC1303M2510 to 0510

Hi,

Our customer is considering change from M2510 to M0510.

Customer's Existing model : +/-100A FS, 2m ohm shunt --> +/- 200mV( 4/5 FS of  M2510 )

So, I think they should use 0.4m ohm shunt for M0510.    (100A * 0.4m ohm = 40mV)

It is correct ?

This is a simple question, but they evaluated it using "0.5"m ohm shunt and it didn't seem to work properly.
