To record a pulse waveform using the PPG100C, follow these setup and calibration details: Connections Plug the transducer into the amplifier but do not connect it to the subject yet.…
MODULATION OF QRS AMPLITUDE Several anatomical and physiological factors determine the amplitudes of the Q, R, and S waves in the ECG of a normal person. These factors include the…
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…
When using electrodes: Prepare the electrode site by removing dead skin—unless recording EDA/GSR—using an ELPAD and cotton swabs with water. If recording EDA/GSR, see EDA (GSR) subject preparation for guidelines.…
Guidelines for obtaining better respiration data when using a respiration belt transducer Avoid noise in the first place Set the RSP100C amplifier to the recommended settings for general respiration recordings:…

Reusable and disposable EDA/GSR electrodes both use isotonic gel but the formulas are different so results will be almost identical but will show a small difference. The researcher should compare…
Parts needed:2 x JUMP100STP100CUIM100C The STP100C receives a digital pulse coming from a stimulus presentation program, either through the 37 pin connector or the 25 pin connector. To route a…
To take a screenshot of BIOPAC software/data for reports or publication: A. Use the Edit Function Choose Edit > Clipboard > Copy graph. This will capture what is seen in…
BIOPAC software is designed to be Section 508 Compliant. Compliance statements have been prepared following the Voluntary Product Evaluation Template (VPAT) for the following software releases: Curent releases AcqKnowledge 5.0 and…
If the positive and negative lead wires were merely swapped, then the signal will just be inverted (not otherwise distorted). The signal may be flipped over either with “Transform >…
When you purchase a system, part of the cost of that system is for a license to run the software. Software is not purchased outright; it is not owned by…
Models designed to infer stroke volumes based on changes in thoracic impedance rely on many simplifying assumptions. These assumptions are not universally valid. Consequently the relationship between measured impedances and…
If you are not seeing a signal from SuperLab in AcqKnowledge, please follow these troubleshooting steps: Make sure the measurement computing card is set up properly. Use this SuperLab Support link.…

MP160 communication can be compromised by a variety of factors, typically indicated by the presentation of dialogs during software startup. Troubleshooting MP160 Communications provides detailed steps to resolve communication errors.
Sometimes harmful voltage surges come from electrostatic discharge (ESD). This is a single, fast, high current transfer of electrostatic charge resulting from one of two conditions. These conditions are: Direct…
Diagnosing Communication Problems MP160 See MP160 Troubleshooting Guide and associated MP160 flow chart. MP150 See MP150 Troubleshooting Guide and associated MP150 flow chart. MP100 For an MP100, the most likely issue is a…
There are several possible issues. Most relate to the manner in which the power spectral density is computed. Before discussing those, a brief mention of data quality is in order.…
On the MP100/MP150: For unipolar recording you need as many amplifiers as you have sites to record from. For example, for 16 electrodes (not including 1 reference and 1 ground),…
It is possible to upgrade an existing MP100 system that uses the older PCMCIA interface option. You will require one of our PLAT100W1 items, which includes software version 3.9.1 for…
USB drivers for BIOPAC hardware are Microsoft certified and meet the USB communication standards at the time the hardware platform was released. Under Windows XP and above, USB drivers are broadcast…
The BIOPAC Hardware Application Program Interface (BHAPI) can be used if the hardware in question is an MP160, MP150, MP36R, MP36, or MP45. The BHAPI is a set of dynamically linked…
Trigger information can be sent to the MP150/100 from a visual presentation system such as SuperLab, E-prime, DirectRT, MediaLab, Inquisit, and Presentation using the STP100C Isolated Digital Interface module. The event…
Volume is computed by integrating the flow rate. Any time that data are integrated, decisions must be made about when to “re-set” the integral. That is, at some point it…
The AcqKnowledge and BSL PRO software has a sophisticated Integration feature that works both online and offline. The algorithm identifies the start or end of each breath and integrates the…
VREF, excitation voltage and reference voltage refer to the same concept. This is the voltage the DA100C series amplifier provides for connected transducers that need to be powered. The excitation…
Our goal is generally to provide but not proscribe choices. As with electrode positioning, decisions about electrode type are best addressed via the literature and discussions with colleagues. That said,…
The best answers for this sort of question are found in the literature and via discussions with colleagues. Decisions about such things are matters of science, not technical support. In…
