Instrumentation Amplifier Detail Information

Instrumentation Amplifier, order code INA-BTA, $59.00
Specifications and User Guide

TROUBLESHOOTING
-Primary Test: Confirm that the gain setting on the sensor is appropriate for the device connected to the Instrumentation Amplifier.
-Secondary Test (when using the INA with a gas chromatograph): If your voltage readings are noisy, you should connect the Earth ground of the Gas Chromatograph to the LabPro ground. To do this, first connect the Voltage Probe that was shipped with your interface to another channel (e.g., CH 2). Then connect the Earth ground to the black lead of the Voltage Probe.
