Feed Timer Troubleshooting
Issue
Understanding how the 5200A calculates sensor reduction
time
Sensor reduction % is
not accurate based on
displayed sensor value(s).
The 5200A displays temperature sensor values to the 10ths
and DO values to 100ths. In reality the 5200A temperature
and DO sensor system values are stored at a much greater
resolution (out to 64 bits). It is the stored values, not the dis-
played values, that are used to calculate the feed timer sensor
reduction.
