With this set up, turn the ECG device under test to maximum sensitivity, turn off the
ac filters (if possible) and confirm that the level of noise is acceptable for tests. For
most tests, this set up is satisfactory without any special efforts. However for the
input impedance test with the 620kΩ is in series the imbalance in impedance can
cause high noise. For this test, the ac filter may be turned on. If the noise is still
excessive, move to an electrically quiet environment or increase the size of the
metal sheet underneath and around the set up.
