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?
Software License Agreement Unless expressly stated otherwise with respect to any ADInstruments software, the following terms shall apply, as noted herein, to software made available by ADInstruments. By installing, copying or using Software (defined...
What devices are compatible with the Kent Device Enabler?
The following devices shipped on or after October 15, 2012 are compatible with the Kent Device Enabler: Kent PhysioSuite (MouseSTAT, MouseVent, RightTemp, CapnoScan) Kent CODA Monitor NIBP System Exception: the CODA-HT system (capable of recording 8...
The Kent Device Enabler is compatible with LabChart for Windows version 7.3.5 and later. Please note that this device enabler should not be used with the ADInstruments branded Rodent NIBP CODA Monitor. To use the ADInstruments branded device with...
Can two individuals sign a single LabChart data file without deeming the GLP regulations invalid?
Yes. If an authorized GLP user wishes to add data to a LabChart file that was previously recorded, and signed, by a separate GLP user, then the digital signatures for both users are attributed to their respective data recordings. Both signatures will...
Can I install my SuperLab software on more than one computer?
SuperLab is a Stimulus Presentation software by Cedrus. Whilst it is possible to install the software on multiple computers, if you only have a single license, you may only use the software on one computer at a given time. Therefore, if one person is...
If an MLT1115 Galvanic Oxygen Electrode is slow to respond to changes in dissolved oxygen and unstable, it may not be correctly configured to be used with a PowerLab. In order to function correctly with the PowerLab's input impedance of 1 MΩ, the...
Firstly, check the wiring of the output cable. The center conductor must be the signal (+) and the outer conductor must be the ground/shield. Measure the voltage directly at the BNC output connector using a voltmeter. The voltage outputs should be as...
When recording PV-Loop data, why is the subject's pressure signal and heart rate lower than expected?
The animal is either over-anesthetized or has lost too much blood during the course of the surgical procedure. Adjust the anesthesia concentration and/or dosage, or choose a more appropriate anesthetic agent. Minimize blood loss during surgery by...
