Go Direct^® Constant Current System (GDX-CCS)

Specifications and User Guide

Troubleshooting

Primary Test:

1. Connect the AC power adapter to the Constant Current System.
2. Connect your sensor as described in the Getting Started instructions for your device. (The green LED will flash to indicate the sensor is connected.)
3. Be sure the dial is turned counterclockwise to the minimum.
4. Connect the red and black clips together.
5. Turn the dial clockwise. The current reading should increase to 0.6 A when the dial is turned to the maximum.
