Description
Enters a description for the measurement site (default: serial number). Use the
description to identify the measurement locations (e.g., Aeration tank 1). The description
is saved with the measurement values in the controller data log.
Selects the measured parameter:
• NT3200sc—NO
-N, NO
3
• NT3100sc—NO
-N (default), NO
X
Sets the measurement units. Options: mg/L (default) or ppm
Sets the measurement interval. Options: 15, 30 seconds, 1, 5 (default), 10 or 30 minutes
Sets the number of saved measurements the controller uses to calculate the average
measurement: 1 to 12 (default: 3). The signal average setting decreases the variability
of measurements. The controller shows and saves the average measurement to the
data log. In addition, the controller updates the relays and analog outputs to the average
measurement.
Sets the cleaning interval: 1 for each measurement (default), 1, 5, 10, 30 minutes, 1,
6 or 12 hours
Note: Changing the cleaning cycle can impact measurement results and the life time of
the wiper blades.
Sets the wiper cleaning cycle:
• Single—The wiper makes one movement, from one side to another, with each
cleaning cycle.
• Double A-B-A—The wiper makes two movements with each cleaning cycle. Starts at
position A, moves to position B and then returns to position A. One cleaning cycle A-
B-A is counted as two movements.
• Double B-A-B (default)— The wiper makes two movements with each cleaning
cycle. Starts at position B, moves to position A and then returns to position B. One
cleaning cycle B-A-B is counted as two movements.
Note: A and B are the two final positions of the wiper movement. Select the correct
setting based on the probe installation. When the wiper stops, it must be in the top
position.
