1.3 Attentions
• Keep the Electrocardiograph away from dust, vibration, corrosive
substances, explosive materials, high temperature and moisture.
• If the Electrocardiograph gets wet, please stop operating it.
• When it is carried from cold environment to warm and humid
environment, please do not use it immediately.
• Do not operate keys on front panel with sharp materials.
• Do not have the product immerged in liquid.
• When cleaning the device with water, the temperature should be lower
than 60°.
• The design of the instrument is considered sufficiently with the safety
requirement, but the observation of the patient and the instrument
can not be ignored.
• The instrument has normal useful life for five years since the first
electrified use.
• The instrument dose not have low-voltage alarm function, it only shows
the battery energy, please change the battery when the battery energy
is used out.
2 OVERVIEW
Through the broading market investigation, our company assembles a lot
of talents in the following majors: the appearance design of the product,
structure design, transmission structure design, and circuit design, they
produced ECG successfully after their deep research and reduplicate tests.
This equipment adopts the thermal recording mode (the key point of thermal
recording technique is the core component---thermal recording probe.
The thermal recording probe is the high-tech component with advanced
component integrated technology, integrating a large amount of heating
elements (8points/millimetre) and its controlled circuit based on the ceramic
basal body. It doesn’t have the false difference which caused by non-
linearity, damping, and incongruence of pen warmth of the traditional hot
pen ECG. In the frequency response which is the important index of affecting
the descriptive authenticity, the product can reach 0.05-150Hz frequency
response which is the world level, aslo the equipment has advanced digital
baseline drifting filter, Alternating Current filter, and Myo- electricity
disturbance filter. The sampling rate of lead signal is 800Hz,
the closure frequency of low pass filter machine with guards against mixes
folds is (-3dB) 220Hz. The sampling rate is higher than the standard of not
lower than 500Hz which made by American AHA Association and European
CSE Association.
