7.1 Summarize
Keep your equipment and accessories free of dust and dirt. To avoid
damage to the equipment, follow these rules:
1. Always dilute according the manufacturer’s instructions or use lowest

Put on a external pace voltage (risetime no greater than 5ms, amplitude of
1mV±0.01mV) to theⅠ,Ⅱ,V1~V6 leads of the electrocardiograph, in order
to determine whether the calibration voltage error is within the range of 5%
through the recorded waveform.
Warning: Be sure to shut down the system and disconnect all power
cables from the outlets before cleaning the equipment.
