Use DFS200 Battery Measurement Probe (with load) to check AED battery level

DFS200 provides the user with the function of measuring voltage to check battery level. The conventional method can’t accurately measure the battery level because of the low load when testing. However, DFS200 battery measurement probe with load...

ECG 3 Lead Tests

It is normal in ECG testing to simplify the approach on the assumption that one test is representative. For example, an input impedance test on V1 and V4 can reasonably be considered representative of tests on the other chest leads.

ECG Test of Input Impedance and Noise

Although not explicitly stated, it’s obvious the ECG standard includes noise. If a test requires the ECG under test to reproduce a test signal accurately within ±5%, it makes no sense to perform the test if the test signal also had said ±20% noise.

ECG Low Frequency Response Impulse Test

Recently Derek Qin of Draeger pointed out that at the end of the MEDTEQ article on ECG filters, the graph showing the effect of a 3mV/100ms impulse on a 0.05Hz high pass filter had a post impulse slope that looked more like 29µV rather than the claimed 29
