Go Direct^® Conductivity Probe (GDX-CON)
Specifications and User Guide

TROUBLESHOOTING
-Primary Test: Take a reading in a solution of known value. A reading close to that value should register.

CALIBRATION
-You do not have to perform a new calibration when using the Conductivity Probe for most experiments in the classroom. However, if your experimental application requires more accurate readings, you should calibrate your sensor.

BATTERY TROUBLESHOOTING
If the sensor can be turned on when connected by USB but not when disconnected from USB, the battery either needs charging or has reached its end of life and can no longer hold a charge. First, try charging the sensor for several hours. If the sensor still won’t turn on when disconnected from USB, the battery has likely reached its end of life. If you intend to use this sensor wirelessly, the battery will need to be replaced. The rechargeable battery in this sensor is covered by a one year warranty but should last two to five years in typical use.
