When the amplified signal for any given channel exceeds the range -10 to +10 volts, the signal will rail. You will see a straight line at -10 or + 10 volts (more likely the reading will be close 9.99 volts). The MP system is designed to work only in the range -10 to +10 volts. The signal could rail for several reasons (which are not exclusive):
The signal is too strong for the current gain setting on the amplifier. Try reducing the gain setting.
You are recording in DC mode when you should be recording in AC mode. If this is the case, make sure DC is off and a switch is set to 0.05Hz HP or 0.5Hz HP.
Your amplifier baseline (offset) is not adjusted properly. Please consult with application note 110 for details on how to make the required adjustments.
The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL526 strip electrodes and CBL246 adapter or with EL500 […]
BIOPAC tools are used for studies in a variety of different fields and disciplines. AcqKnowledge software is one of our universally applicable tools, used by thousands of labs around the world and cited in thousands of peer reviewed publications, such as the following studies… The psychophysiology of guilt in healthy adults. Cognitive, Affective, & Behavioral Neuroscience, 1-18. […]
We had the opportunity to meet lots of researchers at our 4T|Phys Human Physiology Conference this month and demonstrate solutions for life science studies. We presented 39 unique skills sessions, including sessions on measuring blood pressure, recording HRV, and utilizing VR. These studies all apply these skills and further demonstrate how to apply our equipment… Real-Time Personalized Physiologically […]
