-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.

-new order code: INA-BTA
-old order code: INA-DIN
-Gain settings; 150, 75, 7.5, 15, 3, and 1.55%
-Power = 2.5 mA @ 5VDC
-Frequency Response: 0-10kHz (f3dB)
-Impedance : 1MΩ to ground
range resolution (µV)
+/- 1V 580.
+/- 200 mV 144
+/- 20 mV 16
0-1 V 380
0-200 mV 76
0-20 mV 8.1
-Calibrate? No. The manner in which this device works does not warrant calibration.
Newer INA-BTA have an external grounding pin that can be used as a chassis ground to limit noise and dc shift.
