Dissolved Oxygen - Signet 9900 Operating Instructions Manual

Dissolved Oxygen

This is the normal display
and does not time out.
VIEW Mode Menu
Displays temperature at the sensor.
Displays the 4 to 20 mA LOOP output.
Displays Cap Expiration Date MM-YYYY. If sensor cap is missing, - - - - - - - will be displayed.
Bottom line shows one of three states (OFF, ON, PLS) for each of the three relays. Displays remaining
time for CYC LOW or CYC HIGH mode. The relay(s) will remain ON while counting down.
NOTE: (Reset the Timer) In the RELAY menu, select TEST RELAY function. The timer will reset to 0 if
the condition no longer exists when the TEST is performed.
The timer will restart if the condition still exists.
CAL Menu
YES prevents relays from activating while making adjustments, and relays in PULSE mode will suspend
pulsing. Output is held until the user exits the CAL menu. Select YES/NO.
Default = NO.
Allows user to initiate the optional calibration process.
NOTE: Dissolved Oxygen sensors are calibrated at the factory and do not require regular calibration.
Press ► to begin the calibration process (password required). User will be prompted to place sensor in
100% Solution standard. Press ENTER to save value and establish a calibration point.
Allows user to establish an optional second calibration point.
NOTE: Dissolved Oxygen sensors are calibrated at the factory and do not require regular calibration.
Press ► to begin the calibration process. User will be prompted to place sensor in 0% Solution
standard. Press ENTER to save value and establish an optional second calibration point.
This option is only available immediately after a successful 100% Solution calibration.
Resets Dissolved Oxygen calibration to factory settings. After pressing ►, select YES/NO.
Enter date of calibration (mm-dd-yyyy) and initials of calibrator (II).

2610 wiring on page 15.
3-2610-31 setup on page 44.
1. Make sure DISSOLVED O2 sensor type is selected
(see System Setup Menu, page 25).
2. Set Units of Measurement (PPM, %SAT, TOR).
3. Set the Temperature Units (°C or °F).
4. Set Salinity reference value.
5. Set Barometric reference value.
6. If LOOP is used, set the minimum and maximum 4 to 20 mA setpoints.
7. Select source for Open Collector and Relay output (PPM or TEMP).
8. If desired, set up relay functions for your own application.
