绑建心电常见故障（Build common ECG failures） Common troubles and troubleshooting of electrocardiograph Release date: 2008-02-29 Last update time : 2009-09-03 Browse times : 1772 One Notes for the use of electrocardiograph: AC power switch: All state health ECG machines, in addition to the switch keys ON/OFF. Outside, AC power switch is available. The machine is used for alternating current Switch on the AC power switch, The position of the alternating current power switch is beside the AC power line, If the AC power switch is not turned on, be The machine works in a battery powered state, and when the battery is low, the machine shuts down automatically. Charging method: other models of ECG must be charged in the shutdown state, when charging, the panel indicator light flashes, When the battery is full, Indicator change Chang ming. Automatic power-off protection: All ECG machines in the state work while using a built-in battery, If continuous Four Not working together for more than 10 minutes, Is the machine The device automatically shuts down to protect the battery from being wasted. Two Notes on the operation of the electrocardiograph: Use of limb clamp: The corresponding connection measurements must be strictly carried out in accordance with the mark symbols of each limb clamp, Please put your left and right feet together or use only Three Limb clamp, Otherwise it will cause Measured waveform disturbance, inaccurate or erroneous analysis results. The use of suction ball: Please strictly in accordance with the location of each chest electrode connection, and to use Six A chest electrode connection is used by the doctor only V1 , V3 , V5 Conduct Measurements, which can also cause inaccurate waveforms and erroneous analysis results. Please use conductive ointment or alcohol in measuring human body, The chest electrode should be separated separately when wiping the conductive paste or alcohol, Never allow all chest position to be measured at one time Smearing, which will caus
