Setup
Hardware Setup
The following steps can be performed in any order.
1. Connect the Salinity Sensor Probe to the Salinity Sensor. Connect the Conductiv-
ity BNC connector from the probe to the Conductivity input port on the sensor.
Push the BNC connector onto the port and turn the connector clockwise
(left-to-right) until the connector locks into place on the port.
2. Connect the Temperature input plug from the probe to the Temperature input port
on the sensor.
3. Connect the Salinity Sensor to a PASPORT interface.
4. If you will be using a computer, connect the PASPORT interface to the com-
puter’s USB port.
Using the Probe
Before using the Salinity Sensor Probe, soak the probe in distilled water for 5 to 10
minutes. Use a towel to dry any water droplets that are on the probe so that the water
will not dilute the sample that is to be measured.
Submerge the tip of the probe at least 5 centimeters (cm) into the sample to be mea-
sured. Start recording data. Watch the display in your data acquisition program.
DataStudio Setup
If you will be using the Salinity Sensor
with a computer, install the latest ver-
sion of DataStudio first. Check the
PASCO web site at www.pasco.com
for information.
1. When you connect the Salin-
ity Sensor to the computer
through a PASPORT inter-
face, the PASPortal window
will launch automatically (if
DataStudio is not already running).
2. Select Launch DataStudio in the PASPortal window.
A Digits display for salinity, temperature, and conductivity will open automatically.
3. Click to begin data collection.
To view and change the sample rate and other sensor properties, click .
Xplorer and Xplorer GLX Setup
If you will be using an Xplorer or Xplorer GLX in logging mode (not connected to a
computer), connect the Salinity Sensor to the Xplorer or Xplorer GLX, turn the inter-
face on, and press
to begin data collection.
TIPS
DO NOT submerge the
entire Salinity Sensor
Probe in a liquid. The top
end of the probe is not
waterproof.
Use distilled water from a
wash bottle to rinse the
end of the probe before
making another measure-
ment.
DO NOT put the probe in
viscous, organic liquids,
such as heavy oils or eth-
ylene glycol. Do not put
the probe in acetone or
non-polar solvents, such
as pentane.
Clean the electrodes
when necessary by soak-
ing the tip in acid (e.g.,
vineagar or diluted hydro-
chloric acid (muriatic
acid)) and then rinsing
with water.
If the tip is heavily fouled
with organic material,
soak the tip in alcohol or
bleach and then rinse with
water. Gently wipe the tip
with a soft, nonabrasive
cloth towel.
