PLOTS

Real-Time Plot

Starts a real-time plot of one of the flow

variables.

Plot Setup

Sets the real-time plot type (LPM, CFM,

etc.) and the plot scales.

The protocol to communicate with the BB100 is in the

Serial Port Programming Interface

Description

section. With the information contained there, software can be written to

communicate with the BB100 via RS-232.
