Enter the number of hours to display in the monitor window. Sequoia
recommends that you select a value somewhere between 48 and 96
hours to get a good visual idea of how the sediment concentration
has been varying in the past.
If you select a value of 12 hours or less you will not be able to see
what the natural daily variability is, if there is any. In the example
shown here, the display period has been set to 96 hours (4 days).
Below the display period is the setting for the Time Between
Samples - the sample update rate if you like. This value sets the
time between measurements. Since it can take almost 5 minutes to
acquire a new measurement the shortest possible update rate is 5
minutes. Enter the desired time in minutes. In the example shown
here, the time between samples has been set to 15 minutes.
When you click OK the values you have entered will be saved as
default so you do not have to re-enter them if you close the Monitor
program.
Step 4: Set
Alarm Levels The second tab on the Settings window contains the settings for the
Alarm level for each of the four plots. When the value reaches this
Alarm level a visual and audible alarm activate. The alarm is not
activated unless the average value exceeds the Alarm level.
