High Reset
To provide for hysteresis, set this value slightly below the high threshold value. The voltage
being measured must drop below the High Reset value before another alarm can be initiated.
This prevents chattering when a voltage hovers right at the threshold value.
Low Reset
To provide for hysteresis, set this value slightly above the low threshold value. The voltage
being measured must rise above the Low Reset value before another alarm can be initiated.
Accumulator Sampling Rate
Set the time between samples in 10th seconds. For example, “1” is 10 samples per second,
“2” is 5 samples per second, “100” is one sample every 10 seconds, and “1000” is one
sample every 100 seconds. The valid range is 1 to 65535, which represents from 0.1 to
6553.5 seconds between samples.
% Change Alert
% Change alert is the percent change of full scale from the last reported value that will cause
another report. For example, if we are measuring feet of water in a 100-foot tank and we
wish to know a minimum of every 4-ft change, we would set the % Change alert to 4/100 or
4.0%. If our starting value is 30 ft and the tank is rising, we should get an update at 34 ft, 38
ft, 42 ft, etc.
% Change Debounce
% Change de{B}ounce is the amount of time in seconds that the change must exist before the
update can be sent. If, in the example in the previous paragraph, we have the debounce set to
5 seconds and the level rises from 30 to 34 feet for 3 seconds and then drops to 33 feet, no
report would be sent. This programming option helps filter out noise spikes and reduce
airtime usage.
Next Input
This will increment the current input number for modification. If the current input number is
the last input for the RTU, the menu will wrap back to input #1.
Exit
This selection will take the user back to the main menu.
