This restrictor requires dierent calibration procedures than the standard restrictor. For
accurate calibrations, follow the instructions below. Refer to the user manual for detailed
cleaning and calibration procedures.
RDO 100% Saturation Calibration: Water Saturated Air
Use the procedure below to calibrate the Aqua TROLL 700 RDO sensor, or see the next section for an
alternative method.

Turbidity Sensor Calibration
You must calibrate the turbidity sensor with In-Situ's turbidity standard, or formazin. The app
may not automatically detect the formazin concentration. Instead, a eld will appear in which
you can enter the appropriate value. Select Set User Dened to begin calibrating with the
new value. If you are using an In-Situ standard and the app does not automatically detect it,
perform the sensor cleaning and maintenance procedure, then select Retry Auto Detect.
Solution-Based Calibration

Install calibration sleeve onto
restrictor until you hear a click.
Sleeve should be ush with end of
restrictor.
Pour 20-40 mL of DI water into
restrictor.
In VuSitu, click Calibrations from
the Connected Instrument screen
and choose sensor to calibrate.
Gently shake the sonde in a
circular motion to rinse the inside
of restrictor and sensors.
Pour 90 mL of calibration solution
into the restrictor and cover
with the end cap. Follow the
instructions in VuSitu to start the
calibration.
Discard the DI water and repeat
rinsing procedure two more
times with 20-40 mL of your rst
calibration standard.
Fluorometer Calibration
Fluorometer sensors (BGA-PC, BGA-PE, Chlorophyll-A, FDOM, Crude Oil, Fluorescein, and
Rhodamine) require more calibration solution than other solution-based calibrations.
Use a solid-state calibrator for uorometer calibrations if one is available. If solution-based
calibration is required, use 180 mL of calibration solution for accurate calibration.

Fluorescein WT
Remove the calibration sleeve and reinstall the end cap before deployment.
Using Solid State Calibrators
Place the calibrator in the end of
the restrictor.
Connect to the VuSitu mobile
app. Select Calibrations, then
choose the calibration you want
to perform.
Install calibration sleeve onto
restrictor until you hear a click.
Sleeve should be ush with end
of restrictor.
Do not look directly at the sensor LED or point it at the eyes. Doing so can cause eye damage
from UV light emitted by the LED.
Enter the standard value from the
top of the Calibrator.
Follow the on-screen instructions
to complete the calibration.
