Er01
Error of
measurement
Too much noise to detect an
effective pulse signal
Please rest for 2 minutes, adjust the cuff, keep
quiet during measurement, do not move or
talk.
Error of
measurement
No pulse was detected
Error of
measurement
Test results deviate from normal
range
Static pressure
exceeds the set
protection point
Pressure exceeds design ceiling
protection
Measure blood pressure again
Zero overtime
1. During the process of returning to
zero, the air pressure in the cuff
continues to fluctuate;
2. The sensor part of the circuit is
abnormal;
3. Sensor damage.
1. Keep the cuff intact when returning
to zero;
2. Detecting the power supply of the
sensor;
3. Replace the sensor.
Er02
Abnormal cuff
wearing
1. The cuff is not worn;
2. Wearing too loose;
3. Wearing too tight;
4.5s did not reach 10mmHg or 18s
did not reach 25mmHg;
5. After the air pressure exceeds
30mmHg, the air pressure is lower
than 20mmHg due to the looseness
of the cuff;
Adjust the cuff. It is advisable to insert
two fingers just after the tightness
is tied. The cuff mouth of the cuff is kept 2cm
on the elbow socket.
Lo
Power is not
enough
The power is lower
than the minimum
operating voltage.
Replace the battery
Over range alarm
When the test blood pressure value is higher than 280mmhg (excluding 280mmhg), the blood pressure value will continue to
flash at a frequency of 2HZ. When the blood pressure value is lower than 280mmhg, the flicker is released.
Other Information
Even a healthy individual, the blood pressure is constantly changing (presenting a jagged line), so when you make comparative
measurements, you must be in a fixed state (quiet environment)! If the difference is greater than 2.0 kPa / 15 mmHg if the above
conditions are met, or in some cases, in case of irregular hear beat, please consult your doctor.
