SPARKvue and SPARK SLS Setup
Connect the PASPORT interface directly to a SPARK SLS or to a computer using a
SPARKvue supported interface. Build one or more displays for data. Press
to
start data collection and
to stop data collection.
The default sampling rate is defined with Sampling Options. Calibration is performed
with Experiment Tools > Calibrate Sensor. For more instructions on using the
SPARKvue/SPARK SLS, refer to the SPARKvue/SPARK SLS Online Help or User’s
Guide.
Xplorer GLX Setup
If you are using an Xplorer GLX in standalone mode, press
to start data collec-
tion.
Note that the sensor may collect data for probes that are not connected. Hide or ignore
these measurements. To hide measurements that you do not need, open the Sensors
screen (from the Home screen, press
). In the Sensors screen you can also
change the sampling rate and open the calibration dialog box. For more instructions
on using the Xplorer GLX, refer to the GLX User’s 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. 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
thermistor can also be connected to the multi-sensor. The multi-sen-
sor automatically detects the presence of a temperature probe, and it will only collect
temperature data if a probe is connected.
Measuring Temperature
To measure temperature, connect the probe and start data collection. Immerse the tip
of the probe in a fluid or place it in contact with an object. The included stainless steel
probe can be used in both dry conditions and in liquids, such as water and other mild
chemicals and solutions.
Tip: For better chemical resistance, use a Teflon
®
cover (CI-6549).
Temperature Calibration
The temperature measurement can be calibrated; however, for most applications cali-
bration is not necessary. Use a two-point calibration with two standards of known
temperature. Refer the SPARKvue/SPARK SLS, Capstone, or Xplorer GLX Online
Help or User’s Guide for calibration instructions.
Conductivity
The conductivity component sensor measures the electrolytic conductivity of aqueous
solutions. It determines the conductivity by applying an alternating voltage to the
electrode cell at the end of the probe and measuring the resulting current. You can use
the included 10x electrode or an optional1x electrode (not included). In the software
