If you want to change the interval between measurements to avoid granularity issues you can go in Settings > Advanced Settings and modify :

• Data reading period : How often the data is read out from the devices. You should set this to 0, which means as fast as possible.
• Scheduler run period : How much seconds there must be at least between two consecutive control loop executions. Less excecutions mean less data usage, but come at the cost of slower and less accurate control.
