Electrode Impedance Checker helps you record great data

Now available from BIOPAC… EL-CHECK Impedance Checker

Add the EL-CHECK to your recording protocol to measure the impedance between surface electrodes attached to a subject before you begin recording…then correct any noise issues before you begin to record great data!

EMG data recording improves with EL-CHECK

EL-CHECK is suitable for measuring electrode contact impedance for all surface biopotential measurements, including those for ECG, EEG, EGG, EMG, EOG, Bioimpedance and Impedance Cardiography. The EL-CHECK permits simultaneous connection of up to three electrode leads, for quick impedance checking between any two electrodes.

Electrode Impedance Range Indicators: < 5  kΩ, 5-10 kΩ, 10-20 kΩ, 20-30 kΩ, 30-40 kΩ, 40-50 kΩ, > 50 kΩ

Lead Compatibility: Standard female Touchproof (1.5 mm) electrode leads, all BIOPAC electrodes and leads that terminate in female Touchproof sockets, all BN-EL and BN-Adapt series.

Testing Configurations – Switch Selectable: Active (Vin+) to Reference (Vin-), Active (Vin+) to Ground (GND), Reference (Vin-) to Ground (GND)

Effort & Motivation: Using a Hand Dynamometer in the MRI and in the Lab

Many studies use hand dynamometry to objectively quantify exerted effort during experiments most commonly related to the study of motivation.
We’ll focus on this topic and go over everything you need to know to record dynamometry data in the MRI or in the lab. Topics include
– Calibrating for maximum voluntary contraction (MVC)
– Real-time access to the dynamometer signal by third-party applications
– How researchers have used this equipment
– Creating a visual task that gives feedback on exerted effort as well as rewards to the participant
