Description
Sets the name of the analyzer. The name of the analyzer shows on the controller
display and in the log files.
Sets the number of measurements used to calculate the average measurement
shown on the display. Options: 1 (default), 2, 3 or IRREGULAR VALUE.
When SIGNAL AVERAGE is set to 1, signal averaging is disabled.
When SIGNAL AVERAGE is set to 2 or 3, an average reading shows on the display.
For example, the measurement on the display is equal to the last and previous
measurement divided by two when SIGNAL AVERAGE is set to 2.
When SIGNAL AVERAGE is set to IRREGULAR VALUE, the analyzer rejects a
reading that is unusually higher or lower than the latest readings. When a reading is
rejected, the last good reading shows on the display and is saved to the data log. No
more than three consecutive readings are rejected.
Signal averaging corrects for incorrect reading fluctuations that are caused by
bubbles and/or larger particles in the sample.
Sets the type of chlorine measured. If the buffer and indicator bottles have "Free
Chlorine" on their labels, select FREE CHLORINE (default).
If the buffer and indicator bottles have "Total Chlorine" on their labels, select TOTAL
CHLORINE.
Sets the bubble reject to on or off (default). Set BUBBLE REJECT to ON to decrease
noise caused by bubbles in the sample. Air bubbles in the sample can cause the
readings to not be stable.
Sets the chlorine concentration setpoint for the high chlorine alarm—0.00 to
10.00 mg/L (default: 4.00 mg/L).
Sets the chlorine concentration setpoint for the low chlorine alarm—0.00 to
10.00 mg/L (default: 0.20 mg/L).
Shows the analyzer serial number, software version, boot version and driver version.
