Go Direct® Energy Sensor, order code GDX-NRG, $89
Specifications and User Guide
- Primary Test:
1. Make sure the load switch is in the "Internal 30 " setting
2. Connect the sensor to a AA battery.
3. The Potential should be approximately 1.5 volts.
When connected to Graphical Analysis, Choose New from the File menu. A file should open with four graphs, potential, current, resistance and power. If this doesn’t happen, verify that you have a current version of the software.

- Secondary Test:
If the above steps are successful and the unit is still not behaving properly try the following:
1. Zero the Sensors on the Energy Sensor while shorting out the Source terminals. Remove the short.
2. Connect a known voltage source (e.g. a battery) in the 2-5V range to the Source terminals of the Energy Sensor.
3. Connect an appropriate resistor that would draw about 100 mA of current from the source, e.g. for a 3V source use a 30 Ohm resistor.
4. On LabQuest 2, the bar gauges should read the applied voltage and the appropriate current calculated from Ohm’s law. On Logger Pro the Auto ID file gauges should give these same readings.
5. If the step above is successful, the VES is operating correctly and the issue is somewhere in the components that are connected to the Energy Sensor. Double check your wiring, and make sure all connections are secure.
