2. Start the appropriate data-collection software (LoggerPro, Logger Lite, LabQuest App, or Graphical Analysis 4) if not already running, and choose New from File menu. The software will identify the sensor and load a default data-collection setup. You are now ready to collect data.

Do not wrap the cable tightly around the sensor for storage. Repeatedly doing so can irreparably damage the wires and is not covered under warranty.

The Electrode Amplifier is a circuit that allows the millivolt output of an electrode to be monitored by an interface. The electrode is connected to the BNC connector on one end of the amplifier. The cable from the Electrode Amplifier connects to the interface.

The Electrode Amplifier will report values in units of pH. If an ORP or ISE electrode is attached, however, you can choose to read in units of mV. Custom linear 2-point calibrations can also be performed if desired.
