In-Situ Dissolved Oxygen: Clark Cell Calibration Kit for TROLL 9500 - Manual

Instruction Sheet
Multi-Parameter
Water Quality TROLL ®
Catalog No. 48670, 95150
APPLICATION
The D.O. Calibration Kit contains the following for performing an oxygen
saturation point calibration on the polarographic Dissolved Oxygen sensor:
• Battery-powered air pump
• Bubbler cup with aquarium stone, tubing, check valve and pinch valve
• Grey PVC adapter for holding the MP TROLL in top of bubbler cup
• 2 alkaline D-cells
OXYGEN SATURATION CALIBRATION PROCEDURE
1 Install the polarographic Dissolved Oxygen sensor in the MP TROLL (see
instructions packaged with the sensor, or the MP TROLL operator's
manual).
2 Condition the newly-installed sensor as follows:
2A Connect the MP TROLL to a PC and establish a connection in Win-
Situ or Pocket-Situ.
2B Select the MP TROLL in the Navigation tree. All installed sensors will
be displayed. Powering of the D.O. sensor begins as soon as the
software recognizes the D.O. sensor and displays it in the Navigation
tree. This starts the conditioning process.
2C We recommend that you allow the sensor to condition for 2-10 hours
before calibrating.

TIP: Detailed calibration
instructions for the polaro-
graphic D.O. sensor may be
found in section 13 of the Multi-
Parameter TROLL Operator's
Manual, on the Win-Situ

TIP: It is not necessary to maintain the computer connection;
conditioning continues as long as the sensor is installed.
TIP: Testing has shown that 10
hours of conditioning yields
very stable long-term
performance.
TIP: If the polarographic D.O.
sensor is installed when you
receive the instrument, it will
be conditioned and ready to
calibrate.
