Press the same key again to stop recording. Press the Start/Stop key (s) to begin recording data.A Digits display of conductivity opens automatically and shows the data being monitored. Turn on the Xplorer GLX and connect the sensor to a port on the top.Touch “Start”( ) to begin recording data.In the sensor parameter screen, touch the measurement, and then touch ‘Show’ to open a graph display of the measurement.The sensor parameter screen opens and shows the list of measurements for the sensor. Connect the sensor to a SPARKvue-compatible interface and start the software.Click “Record” ( ) to begin recording data.Click one of the display templates in the Capstone workbook page, or double-click an icon in the “Displays” palette to open a specific data display.Confirm that the sensor’s icon appears with the interface’s icon. Click the “Hardware Setup” icon in the Tools palette to open the “Hardware Setup” panel.Start the PASCO data acquisition software.
Making Measurements Using PASCO Capstone Software Press the button with the flashing LED to select the proper range.Īlways use eye protection, gloves, and an apron when working with chemicals. The green light emitting diode (LED) for that button will shine.īlink, and the LED in the button for the next higher range flashes. To select a range, press one of the Range Select Buttons on the sensor. The water glass range is 0 to 1000 microsiemens per centimeter, the chemistry flask range is 0 to 10,000, and the ocean wave range is 0 to 100,000. The three ranges are represented by the icons next to the range select buttons. NOTE: If more distance is needed between the sensor and the interface, plug the sensor into a Sensor Extension Cable (optional) and then plug the cable into the interface.
The sensor is designed to work with a PASPORT-compatible interface (such as the UI-5100 850 Universal Interface) and PASCO data acquisition software (such as PASCO Capstone) to measure electrolytic conductivity. In these applications, conductivity has the advantage of an almost direct relationship with impurities, especially at low concentration.The sensor has three ranges. When dealing with a chemical solution ranging from extremely dilute to very concentrated chemical, use of conductivity units of S/cm and mS/cm are common. The Systeme International (SI) unit) for conductivity is the siemen per centimeter (S/cm). This sensor can be used to explore the effects of temperature and concentration on the electrical transport properties of aqueous solutions. These measurements can be used to investigate factors that influence the electrical conductivity of liquids. The PS-2116A Conductivity Sensor measures ionic and non-ionic molecules in aqueous solutions.
