MECG 2.0 Test System | User Manual
11
For connecting the ECG device under to
the USB module, use the “ECG
breakout box” provided. Alternately the ECG device under test can be directly
connected to the USB module using a male D15 connector. The pinouts are:
1 - RA
4 - RL
7 - V3 (V4)
10 - V6 (V1)
2 - LA
5 - V1 (V6)
8 - V4 (V3)
3 - LL
6 - V2 (V5)
9 - V5 (V2)
Note:
For systems after September 2011, V1 ~ V6 are reversed as shown in the
brackets.
3.3 Environment, Noise reduction
A noise free environment is necessary for testing ECG equipment. This can
be achieved relatively easily by using a metal bench or metal sheet
underneath the ECG device under test, the WhaleTeq MECG test unit, and
also connecting together the ground as shown:
With this setup, 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.
