5561 probe/cable users should ALWAYS disable the conductivity system -
since there is no conductivity sensor in use to accurately compute a
salinity value.
Changes to salinity affect the DO mg/L value. -
Changes to salinity do not affect the DO %Sat value. -
The DO system uses the temperature sensor value regardless if tempera- -
ture is enabled. It is important to verify that the temperature sensor is
measuring accurately.
Two Range Controls for DO
The 5200A DO system has two low and two high control ranges. This dual range
allows for more control over oxygen levels in the system stream. Example - DO
range low one system becomes active, an air injection system energizes when properly
wired and configured to relay #1. The DO level continues to fall. Range low two
system becomes active and a pure oxygen injection system energizes when properly
wired and configured to relay #2.
Directions to Configure DO Sensor
Connect probe assembly - 1. page 60.
Enter DO Sensor Setup menu 2.

Press 6. to save configuration and return to Run Screen.
Notes:
DO set point, control, and alarm values are always entered in mg/L re- -
gardless of display format.
DO set point, control, and alarm values can be up to three (3) characters, -
excluding decimal point. Values will truncate to 10ths when 10s digit
is configured.
5200A calculates the correct %Sat value based on configured elevation -
during calibration.
When DO range low 2 or DO range high 2 are active with energized -
relays, only the range low 2 and range high 2 control messages and icons
display at the control menu and Run Screen regardless if DO range low
1 or DO range high 1 relays are also energized.
