The amplifier board amplifies the bipolar limb leads (L1, L2, L3) and calculates and amplifies the three unipolar limb leads (aVF, aVR, aVL).

Inputs: reference, L1, L2, L3.
Outputs: L1, L2, L3, aVF, aVR, aVL.

main characteristics:

• isolated inputs and amplifier (high electrical protection)
• internal gain of 1000
• external settings of the gain: 0.25, 0.5, 1, 2, 4
• signal input as monopolar or bipolar derivations
• external settings of the low-pass filter: 35 Hz, 100 Hz, 200 Hz, 500 Hz.
• external settings of the high-pass filter: 0.05, 0.2, 0.5, 1
• output of 1 mV for calibration

For on-site calibration of this ecg amplifier board, we offer an ecg calibrator device.
