Common mode rejection
(The notch filter is turned off.)
50/60Hz Notch Filtering The monitor provides software filtering against the 50/60HZ
industrial frequency.
In monitor and surgery modes, the 50/60HZ filter will be turned
on automatically.
In diagnostic mode, the 50/60HZ filter will be turned off.
Input offset current ≤0.1μA (except currents to drive leads)
Differential input impedance ≥ 5MΩ
Input signal range ±8mV (peak-to-peak value)
Accuracy of input signal
reproduction
Methods A and D were used to establish overall system error and
frequency response according to EC11.
Auxiliary current (Leads off
detection)
Active electrode: < 0.1 μA
Reference electrode: < 1 μA
Patient leakage current < 10uA
Recovery time after
defibrillation
< 5s
Calibration signal
1 mV (peak-to-peak value), precision: ±5%
ESU protection Incision mode: 300W
Congelation mode: 100W
Restore time: ≤10s
The monitor complies with the requirements of ANSI/AAMI
EC13 Section 4.2.9.14.
ESU noise control The monitor uses the ECG leads meeting the requirements of
AAMI; based on the ECG baseline, the peak noise ≤ 2 mV
The monitor complies with the test method in EC13 Section
5.2.9.14.
