Go Direct^® Melt Station (GDX-MLT)

Specifications and User Guide

Troubleshooting

Primary Test:

1. Plug in the Melt Station using its AC adapter.
2. Turn the control dial to any temperature setting, including Rapid Heat.
3. Connect your sensor as described in the Getting Started instructions for your device. (The green LED will flash to indicate the sensor is connected.)
4. The Melt Station should automatically be identified, and a temperature reading will appear.
5. Click Collect to begin data collection.
6. The temperature reading should steadily increase as the heating block warms up.

Calibration

Calibrate? No. The temperature sensor embedded in the aluminum heating block of the Melt Station will never need to be calibrated. The sensor is carefully calibrated before it ships, and this unique calibration is stored on a smart chip in the sensor. Note: There is no method to perform a calibration of this sensor in any of our software programs.
