- Connect to Insight (for instructions, see Connecting to Insight software).
- Select .
Enable the Low H2O2 threshold feature by sliding the selection switch to the right.
When enabled, the Low H2O2 threshold feature remains in use also after probe reset.
- In the Activation level field, define the H2O2 level where the Low H2O2 threshold Activation delay starts.
- In the Activation delay field, define how long it takes for the output to be forced to zero after the H2O2 measurement falls below the Activation level value.
- In the Deactivation level field, define the H2O2 level where the Low H2O2 threshold Deactivation delay starts.
- In the Deactivation delay field, define how long the H2O2 measurement must remain above the Deactivation level before normal measurement output is resumed.
- Take the settings into use by selecting Save.
Example: Low H2O2 threshold feature activated at 3 ppm and deactivated at 10 ppm
- Activation level is set as 3 ppm H2O2 and Activation delay as 1800 seconds (30 minutes).
- Deactivation level is set as 10 ppm H2O2 and Deactivation delay as 10 seconds.
- When the measurement falls below the 3 ppm Activation level, the Activation delay of 30 minutes starts. During the 30-minute Activation delay, all measurements (whether within or outside of the configured activation levels) are output normally.
- After the 30-minute Activation delay has passed, the H2O2 output is forced to 0 ppm.
- The measurement output stays forced to 0 ppm until the actual measurement remains over the Deactivation level of 10 ppm for the set Deactivation delay of 10 seconds.
- When the measurement has remained over
10 ppm for 10 seconds, normal output resumes.
Note that the instant change from the forced 0 ppm output to the actual measurement can cause a quick increase in the measurement output reading.
