12. Technical Data
Classification:
According to the type of protection against electric shock, it can be classified as
internally powered equipment. The device’s application type is CF and it is a
movable common facility with no defibrillator or protection.
Operating Environment:
Operation Temperature: 5℃～40℃;
Atmosphere Pressure Range: 86kPa-106kPa;
Operation Humidity: ≤80%，no condensation;
Operation Voltage: DC 3V (+0.3V, -0.8V); 2 AAA batteries.
Storage Environment
Storage Temperature: -20℃～55℃
Storage Humidity: ≤93%, no condensation
ECG Measurement:
Channel amount: 1 (difference input)
Measuring electrodes: Four integrated metal electrodes.
Three Measuring parts: The signals measured can be lead [I]（between right and left
hand）and approximate lead [II] or lead [III] (between both
hands and the chest).
Note: The signals measured by the device positioned from the right hand and left
hand is lead [I] on a standard surface ECG. The signals measured by the device
positioned from the right hand and left chest best approximates a frontal plane lead
such as lead [II] on a standard surface ECG.
