- 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 aect the DO mg/L value.
- Changes to salinity do not aect the DO %Sat value.
- e 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
e 5200A DO system has two low and two high control ranges. is dual range
allows for more control over oxygen levels in the system stream. Example - DO
range low system becomes active, an air injection system energizes when properly
wired and congured to relay #1. e DO level continues to fall. Range low two
system becomes active and a pure oxygen injection system energizes when properly
wired and congured to relay #2.
Directions to Congure DO Sensor
1. Connect probe assembly - page 61.
2. Enter DO Sensor Setup menu
Menus →Sensor Setup→DO

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 congured.
- 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.
- See 30 Second Sensor Hold O - page 141.
