Introduction
The PS-2169 Water Quality MultiMeasure Sensor combines four sensors in a single
unit:
• Temperature
• Conductivity
• pH, ORP and ion-selective electrode voltage
• Dissolved Oxygen (DO
2
)
When connected to a PASPORT interface, the multi-sensor collects data at up to 20
samples per second from each component sensor. You can use just one component
sensor at a time or any combination simultaneously. If you have a PASPORT interface
that supports multiple sensors, or if you have more than one interface connected to
your computer, you can use the Water Quality MultiMeasure Sensor in combination
with other PASPORT sensors.
Note: No electrical interference will occur between two or more probes connected to a single
Water Quality MultiMeasure Sensor.
Sensor, Interface, and Software Setup
Connect the multi-sensor to your PASPORT interface as pictured (right).
Connect any or all of the included probes to the multi-sensor. (You can leave
any probe disconnected if you do not plan to use it.) If you will be using an
ion-selective electrode or oxygen reduction potential electrode, connect it to
the pH/ISE/ORP port.
Follow the instructions below to set up the multi-sensor with DataStudio
software (if you are using a computer) or the Xplorer GLX (if you are using
it standalone without a computer).
For detailed information about each of the multi-sensor’s component sensors
see “Temperature” on page 3, “Conductivity” on page 3, “pH/ISE/ORP” on
page 4, and “Dissolved Oxygen” on page 6.
Note: Only the tips and handles of the probes should be immersed in liquid, keep the
cables, connectors and body of the multi-sensor dry.
DataStudio Setup
If you are using a computer, connect the PASPORT interface to the computer and start
DataStudio. (Refer to the documentation that came with your PASPORT interface for
instructions on connecting it to your computer.) In DataStudio, click the Start button
to begin data collection; click the Stop button to stop data collection.
Note that the sensor may collected data for probes that are not connected. Hide or
ignore these measurements. To hide measurements that you do not need, open the
Experiment Setup Window by clicking the Setup button. In the Setup window you
can also change the sampling rate and open the calibration dialog box (see Appendix
A). For more instructions on using DataStudio, press F1 to open DataStudio’s on-line
help.
