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 one 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.

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.
