Feed Timer Troubleshooting
Issue Understanding how the 5200A calculates sensor reduction
time
Sensor reduction % is
not accurate based on
displayed sensor value(s).
e 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.
