Common mistakes/general troubleshooting
-
Make sure the unit is turned on and connected to the computer.
-
Check for the green circular icon next to the Start button, which indicates that the unit is connected to the computer.
- If necessary,Ā Troubleshoot MP200 Ethernet Communication.
-
-
Make sure amplifiers are not set to the same channelāeven if some of the amplifiers are not used.
-
Check the switch on top of each amplifier (for some amplifiers the switch is in the front because they use multiple channels).
-
- Calibrate and scale the signalsĀ (MP Menu > Set Up Channels).
- Set the sample rate(s) and recording length (MP Menu > Set Up Acquisition).
- Adjust the display scales so the data is visible (Display menu > Autoscale waveforms).
- Use correct ground and avoid ground loops.
- ToĀ record EDA/GSR with other biopotential signals (ECG, EEG, EOG, EGG, EMG, ERS), BIOPAC recommends using CBL205 connected to one ground on any of the biopotential amplifiers. The subject will be grounded through the Vin- of the EDA electrodes, but in some cases it is necessary to have more than one ground; in such cases, use an AC-coupled lead adapter (CBL205) to prevent ground loops.
- For example, if, while recording a biopotential and EDA/GSR you have to remove the EDA electrode during a stage of the experiment, you will still want to have a ground for the biopotential. Connect theĀ Vin- lead of theĀ EDA as ground, and connect an AC-coupled ground to the biopotential amplifier. The result is that you will always have a ground and no ground loops.
- Ground loopsĀ can be a problem whenĀ using any two of the following amplifiers at the same time: EDA100C (or GSR100C), EBI100C, or NICO100C,Ā but there areĀ setup options if absolute measurements (i.e., SCL) are required:
- Use two wired amplifiers (EDA100C/GSR100C with NICO100C)Ā with a single MP200 System by adding the Isolated power supply IPS100C, interface amplifier HLT100C, isolator OUTISO, and cable CBL100.
- Use a single MP200 system and opt to record EDA/GSR wirelessly and Cardiac Output wired.
- Use two MP200 systems, with one of the two units connected to each system or two BioNomadix amplifiers.
- ToĀ record EDA/GSR with other biopotential signals (ECG, EEG, EOG, EGG, EMG, ERS), BIOPAC recommends using CBL205 connected to one ground on any of the biopotential amplifiers. The subject will be grounded through the Vin- of the EDA electrodes, but in some cases it is necessary to have more than one ground; in such cases, use an AC-coupled lead adapter (CBL205) to prevent ground loops.
