Also, you&#8217;ll need to prepare two standard solutions of known concentrations to calibrate your electrode. The company that sold the electrode to you will have info about suitable standard solutions.<\/p>\n<p>Please follow the steps below to calibrate your electrode.<br \/>\n1) Connect the electrode to the Electrode Amplifier. Connect the Electrode Amplifier to an interface (LabPro, LabQuest &#8211; any model , or Go! Link) and connect the interface to your computer. Run LoggerPro 3.<br \/>\n2) Place the electrode in one of the two standard solutions.<br \/>\n3) The software should display readings from the Electrode Amp in milliVolts (mV). If it does not, open the Experiment menu and choose Change Units -&gt; mV.<br \/>\n4) Open the Experiment menu and choose Calibrate -&gt; Electrode Amplifier.<br \/>\n5) In the calibration window, click on the button that says Calibrate Now.<br \/>\n6) Watch the potential, in V, displayed in the middle right of the calibrate window. When the potential stabilizes, type in the concentration of the standard under Reading 1 and click the Keep button.<br \/>\n7) Move the electrode to the 2nd standard solution, and repeat Step 6 for Reading 2.<br \/>\n8) Click Done. LoggerPro 3 will use this calibration for your experiment.<\/p>","protected":false},"excerpt":{"rendered":"<p>NOTE: The 3rd-party electrode must have a BNC connector at the end of its cable to connect it to the Electrode Amplifier.
