TIDM-1019: Meter constant error

Part Number: TIDM-1019

I've purchased an eval board for the MSP430FR6047 Water Meter. I use transducers from Audiowell (same as those used in documention).

The pipe with transducers is on a testing bench with a flowrate (water) fixed at 500L/h.

I read the mean value of the flowrate on USS, and I'm able to calculate the new "Meter constant".

The problem is, when I want to change the default value (12742000.00) by the new one (199688059.70), I've the following error " Non-advanced parameter error : Invalid Meter Constant"

My version of USS : USS_02_40_00_00

On the old version, the idea was to divide my meter constant by 10 and do the modification in hmi.c and ussDCCommandHandlers.c

But the code is not the same with the last version, What can I do ?

 

Thank you !
