AECG100 | User Manual
6.1
Self-calibration
Self-calibration assists the user calibrates the AECG100 to quickly
confirm the signal quality before testing, not to replace the original
calibration service recommended every year. Please follow the steps
below to conduct self-calibration.
1.
Set up the parameters of the AECG100
AP to “Square, 5 mV, 0.1
Hz
” and output to the RA lead electrode as the figure shown
below:
Figure 83: AECG100 Interface Setup
2.
Connect the multimeter to RA and LA of the AECG100, and measure
the DC mV. The value should be in 1% of 5 mV because the output
amplitude of the AECG100 gives alternating 5s (0.1 Hz square wave)
phases at -2.5mV and +2.5mV, which the multimeter is zeroed
(delta function) at one phase (e.g., -2.5mV), with reading taken
from the other phase (e.g., +2.5mV) to obtain the 5mV peak-peak
value.
Note: Please use the multimeter which is 6 1/2 (6 1/2 digits) or more.
