Battery level indicator. The three segments represent the
battery charge level. The symbol flashes red when the battery
capacity is low.
2
The SpO
2
value shows the blood oxygen saturation level
expressed as a percentage.
3
Bar graph for pulse amplitude. Indicates the dynamic pulse
amplitude and rate. As the detected pulse becomes stronger,
more bars light with each pulse. The reverse is true for weak
pulses. The colour of the bar graph is an indicator for signal
quality:
Green:
good signal quality, very accurate measurement.
Yellow:
average signal quality, measurement may be
inaccurate.
Red:
poor signal quality, unreliable measurement.
4
Pulse rate in beats per minute.
5
Pleth waveform
The reading is automatically adjusted to the pulse strength;
therefore, a waveform with strong amplitude should be visible
at all times.
6
Multifunctional button
- switch device on (short press)
- change/rotate display (short press, when the device
