1.DESCRIPTION
The ModelヽVS‑540‑15 is an Auto lnflationヽ Vst I)igital Blood Pressure Monitor.
The readings in each function are digital displεり
ed on 7 digits LCD panel.
STATUS INDICATION shows Deflation,Inflation,Palpatory Wave and Battely Weak.
ERROR MESSAGE CODE includes Battely Weak,itis impossible to measure the blood pressure
accurately when ERROR MESSAGE CODE appears.
BATERY POWER is monitored when the unitisturned on and a、 varning、、■u be displaり ed
ifit is too、 veak.
AUTOMATIC AIR INFLATION inflates the cur pressure by an intemal alr pump.
AUTOMATIC AIR DUMP VALVE dumps■ le pressure in the cuff automatically when
the rneasurementis over or error has becn occurred.
AUTOMATIC POWER SHUT OFF:
The unit、vill automatically turn offifit is not operated for about 180 seconds or lnore.
