Hello, i built dyno unfortunately i had to use gear ratio because retarder was spinning to slow

I need help to set it up correctly i want to use MOI and  Retardation data.

I have 61cm diam. rollers, one roller rotation is 3 rotations retarder

RPM sensor is mounted directly to rollers 30tooth

What should i do with rpm settings and load cell? What i understood it will measure 3x less nm then on rollers??

The only thing you need to do is to set 10 as the Pulses per revolution. The rest is as normal. You can measure the MOI using the wizard or manually as any other setup. You need to set the gear ratio too, but no different from other setups.
