Calibration values

If the Cal 1 and Cal 2 values are very close to zero, check to make sure that:

the amplifier is not in AC mode;
the filter switches (on the front of the amplifier) are not set to 0.05 Hz HP or 0.5 Hz HP;
the amplifier channel switch is not set to the same number as another amplifier or device (UIM100C; HLT100C)

Also, increase the gain setting if possible.

Associated Applications: Psychophysiology, Sleep Studies, Cardiovascular Hemodynamics, Noninvasive Blood Pressure Monitoring, In-vitro Pharmacology, Laser Doppler Flow, Pulmonary Function, Exercise Physiology, Biomechanics, Remote Monitoring

Associated Application Notes: 101 - Transducer Calibration and Signal Re-Scaling
