Analyzer Overview
3.6.3 Measurement cycle
The following flow chart illustrates the logic used during the measurement cycle.
3.6.4 On-line measurement
On completion of each rinsing time, the analyzer starts the on-line measurement step. The
sodium concentration is shown on the display panel and output via the RS485 link.
At the end of this step, the analyzer refreshes the 4-20 mA outputs and alarm relays, writes data
to the analyzer memory and the display panel. The concentration displayed is the average
concentration of the final minute of the on-line measurement step.
