Preparation
(1) Connect the PPG probe assembly to the probe connector #1 or #2.
(2) Make sure Mode 1 LED (AC mode) illuminates. If
not, press MODE button to select Mode 1 for AC
mode.
(3) Check that the face of the PPG sensor is free of
stains. Clean it if necessary.
(4) Make certain that room temperature is comfortable and, especially, that the skin
surface where the probe is to be mounted is warm. Cold constricts superficial blood
vessels and thus jeopardizes the accuracy of PPG measurements.
Examination Procedure
(1) Apply the sensor with the clear side against the skin surface, and fix it in place using
Velcro strap or double-sided clear tape or PPG probe clip (Option).
(2) The gain is automatically adjusted and the PPG
waveform is shown on the LCD.
(3) When the waveform gets stable and rhythmic,
press INF/DUMP or probe button* to freeze the
waveform.
Press PRINT button to print the waveform of last 5
sec., if necessary.
Note: *When PRB-KEY is on Freeze mode.
(4) If you wish to save the data on the memory, see
“§ 4-2-7-a. MEMORY - STORE”.
