When connected to a PASPORT interface, the multi-sensor collects data at
up to 200 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
General Science MultiMeasure Sensor in combination with other
PASPORT sensors.
Sensor, Interface, and Software Setup
Connect the multi-sensor to your PASPORT interface as pictured (right).
Connect the included temperature and voltage probes to the ports on the
sides of the multi-sensor. (You can leave either of the probes disconnected
if you do not plan to use it.)
Follow the instructions below to set up the sensor with DataStudio software
(if you are using a computer) or the Xplorer GLX (if you are using it stan-
dalone without a computer).
For detailed information about each of the multi-sensor sensor’s component sensors
see below on this page and the next page.
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.
The General Science MultiMeasure Sensor always collects sound-level, light, and
voltage data, but collects temperature data only if a temperature probe is connected.
The default sampling rate is 2 Hz. To change the sampling rate or hide measurements
that you do not need, open the Experiment Setup Window by clicking the Setup but-
ton. For more instructions on using DataStudio, press F1 to open DataStudio’s on-line
help.
Xplorer GLX Setup
If you are using an Xplorer GLX in standalone mode, press
to start data collec-
tion. The General Science MultiMeasure Sensor always collects sound-level, light,
and voltage data, but collects temperature data only if a temperature probe is con-
nected. The default sampling rate is 2 Hz. To change the sampling rate or hide mea-
surements that you do not need, open the Sensors screen (from the Home screen,
press
). For more instructions on using the Xplorer GLX, refer to the GLX
Users’ Guide.
Temperature
Use this component of the multi-sensor to measure the temperature of a fluid or
object. The measurement can be displayed in units of °C, °F, or K. (In DataStudio,
click the Setup button to change units.) You can use the included stainless steel probe
or a different probe, such as the Fast-response Probe (PS-2135) or Skin/Surface Probe
(PS-2131). PASCO physics apparatus containing an embedded 10 k
Ω
thermistor can
also be connected to the multi-sensor. The multi-sensor automatically detects the
