Electro-Chemical Devices (ECD) CA6 Hardness Analyzer - Manual (Page 76)

11.1 Analysis Cycle
The programmed sequence for the Analysis Cycle is detailed in the following table. This program
assumes that the sample is connected to the Left side of the selection valve (Sample Port #1) and
Deionized water or Calibration solution is connected to the Right side of the selection valve (Sample Port
#2).
Step 30 is user configurable to allow up to 15 minutes (900 seconds) between Analysis Cycles. To enter a
time other than 30 seconds go to PROGRAM > SETTINGS > Cycles Wait and enter the new time in
seconds.
