Settings
I-Time
Integration time or dampening - can be set up to 999 seconds
Unit
”%”, ”ppm”, ”g/l”, or ”mg/l”
Alarm Relay
”-” ”#1”, ”#2”, or ”#1 and #2”. Check that the relay is not being
used for cleaning
Analog
”None”, ”Channel 1”, ”Channel 2”, or ”Both”. Pick which analog
output contacts are to be used with sensor
Cleaning

Interval min
0-999 minutes, time between cleaning cycles
Length sec

Calibrate
Take sample
No, Zero, #1, n#2, #3, #4, #5. Sensor stores current MS (light)
value in memory and you enter a lab solids value below to
complete calibration.
Con
Current concentration, (same as shown in the main menu)
Sample #1
Lab test – consistency/suspended solids value for Sample 1
Sample #2
Lab test – consistency/suspended solids value for Sample 2
Sample #3
Lab test – consistency/suspended solids value for Sample 3
Sample #4
Lab test – consistency/suspended solids value for Sample 4
Sample #5
Lab test – consistency/suspended solids value for Sample 5
