Electrocardiogram Wilson Network

It is a multiple electrocardiogram (ECG) Wilson network, it

has to be connected with KL-74001 GPS amplifier module to measure ECG waveform. There are seven ECG leads outputs including:

Lead I, Lead II, Lead III, aVR, aVL, aVF, and one chest lead. The quantities of ECG leads used should be identical to the quantities of KL-74001 GPS amplifier modules. Besides KL-74002 also has a single lead output for signal comparison. The ECG lead could be selected by the lead switch, and its output must be connected to KL-74001 GPS amplifier module.
