Should the Pod port Inputs or Bio Amp Inputs on an Education Series PowerLab be used for recording signals from an isolated nerve?
The Education Series PowerLab's Deutsches Institut für Normung (DIN) 8-pin Pod inputs and Association for the Advancement of Medical Instrumentation (AAMI) 6-pin Bio Amp input are both suitable differential inputs for recording selected...
Can I import data into LabChart from Delsys EMGWorks software?
Data that has been previously recorded in Delsys EMGWorks software, can be exported as a *.csv file. This can be opened in Excel or similar and then saved as a *.txt file which can subsequently be opened by LabChart. This is achieved by opening...
Can Delsys EMG Sensors be used inside MRI machines?
Delsys EMG systems are not approved for use in MRI machines. MRI machines make use of very strong magnetic fields that may induce unwanted currents in metallic objects they traverse. The sensitive electronic components used in Delsys EMG systems will...
Why is the perfusion pressure too high in my hearts using a compact Langendorff system?
Our compact Langendorff systems such as the Rodent Langendorff Apparatus , utilize the STH Pump Controller to maintain the perfusion flow and pressure. Here are some ideas to help you troubleshoot your system for potential problems: PRESSURE ·...
Is the Equivital sensor belt MRI compatible?
Equivital’s LifeMonitor is a sensor worn on the body which measures multiple physiological parametersfrom a single device. The system is contained within a " belt " worn on the chest. The belt system contains components that make it UNSAFE for use in...
The Rat Telemeter tab (see below) in ConfigSoft will have all the functions required to setup and control the Optogenetics Telemeter. By selecting the Optogenetics Telemeter Setup button, the corresponding window will appear with the current...
When using Arithmetic on Spectrum Channel Calculations, why does the output look wrong?
A range of Spectrum channel calculations are available in LabChart. Like many other calculations which produce discrete results, these are displayed using step interpolation, i.e. a series of connected horizontal lines. However if you create an...
How many Wii Balance Boards can be used in the same room?
The number of Wii Balance Boards that can be used with multiple instances of LabChart in the same room is dependent on many factors such as the: proximity of the Bluetooth receivers to each other number of Wireless Local Area Networks (WLAN) present...
The excitation voltage for a current generation ADInstruments Bridge Amplifier is set by an external resistor between Pin 5 and Pin 8 of the Bridge Amplifier's DIN connection. While the Bridge Amplifier has a default excitation voltage of either 0V...
What is an Anti-Aliasing Filter?
Before we can discuss the use of these types filters with an ADInstruments Powerlab , it is import to understand what aliasing actually is. According to the Nyquist theorem, in order to resolve a signal component correctly, the sampling rate needs to...
The Millar Ventri-Cath catheters provide high-fidelity pressure, volume and internal ECG signals when connected to the MPVS Ultra system. Four different spacings of the 12 conductance electrodes (ten volume segments) are available. The following...
Does the LabChart 8 software make use of multi-core processors?
Most modern computers contain processors with two to six cores which read and execute program instructions. Having multiple processor cores allows more than one task to be performed simultaneously. This makes the computer faster. There are normally...
PV Loop calculates most of these parameters, but because the regression equations are in a different form, some of the values have to be converted so that they are comparable with the values calculated by PVAN. The conversion equation for each...
How to convert Skin Conductance Level (SCL) to Skin Conductance Response (SCR) using LabChart?
The FE116 GSR Amp is a fully isolated Galvanic Skin Response amplifier with low voltage, 75 Hz AC excitation and automatic zeroing. The low-voltage AC excitation reduces the electrode polarization artifacts found in DC systems. The amplifier itself...
Why do the units for spectral Power parameters differ in different versions of LabChart's HRV Module?
The spectral analysis parameters calculated by LabChart's HRV module (Total, HF, LF etc) are based on the RR interval signal, which is generated by the beat detector first analysing the raw data. These RR intervals are typically measured in ms. The...
What is the formula used to calculate the Resting Energy Expenditure (REE) in the metabolic module?
The formula that is used to calculate the Resting Energy Expenditure (REE) in the LabChart Metabolic Module is as follows: REE = 16.318VO 2 + 4.602VCO 2 This is an adaptation of the abbreviated Weir Equation which states that: REE = [3.9 (VO 2) + 1.1...
Will LabChart 7 open my old Chart/LabChart data files?
LabChart 7 for Windows and LabChart 7 for Mac will open files from the following versions of Chart and LabChart: Chart version 2.5 for Mac and later Chart version 3.0 for Windows and later LabChart 6.0 for Mac and later LabChart 6.0 for Windows and...
The Optogenetics Telemeter can only be used with the TR190 Configurator and TR181 SmartPads, with some requiring a firmware upgrade (see Table 1) For further technical assistance with this or any other issue, please contact ADInstruments Technical...
Why is it not possible to manually adjust the identified QRS Maximums in the ECG Analysis Module's Averaging View?
Inability to adjust the QRS Maximum manually in the Averaging View is expected behavior in Chart/LabChart. The QRS Maximum is used to identify each ECG event and define all of the associated parameters (P wave, T wave, QRS start, etc.) in the ECG...
What is ADInstruments Software License Agreement?
