AD5560 current transfer

Question

hello, I have a ad5560 evaluation board, how could I transfer the voltage of the MEASOUT pin into the real current ? 
 for example: I set measure current and the measuring range is 2.5mA, I read the register of ad7685 to know the voltage of the MEASOUT is 2.96V, what&rsquo;s the real current?

Hi koob, 
 
 I assume you are operating in the "Force Voltage Measure Current (FVMI) configuration". If this is the case, I also assume that you know that what you're seeing at the MEASOUT is the voltage representation of the actual current. Please refer to tables 9 and 10 of the datasheet as they will give you the necessary transfer functions to use depending on your MI and MEASOUT gain settings. 
 
 Thanks,

Hi gelo, 
 
 Thank you for such a quick response! I have been troubled by this issue for several days now. I realized that I mixed up the gains of 0.2 and 1. 
 
 Thanks,
