1 Choose the appropriate sensor.
Plug the sensor connector into the rear of the monitor.
Do not let the sensor lead hang over the monitor,
as it may impair SpO2 measurement!
C-Lock ECG synchronization (optional)
If the patient is extremely mobile or has a very low arterial
flow, the signals from the SpO2 measurement can be
amplified with the aid of C-Lock ECG synchronization.
In this case, the monitor receives two separate signals
reflecting the cardiac activity:
an optical signal from the SpO2 sensor
and
an electrical signal from the ECG monitor.
The monitor uses the R-wave of the ECG signal to
detect the pulse and for synchronization with the
SpO2 measurement.
● Connect the ECG signal from the ECG monitor to the
rear of the monitor by means of a lead and pawl-type
plug.
Prerequisites for the electrical signal and pin
assignment can be found in the »Technical Data«
on page 121.
In the event of a delayed ECG signal
Synchronization may be impaired if the ECG signal is
delayed by more than 40 milliseconds relative to the
QRS complex.
The monitor must be operated without C-Lock ECG
synchronization whenever there is any suspicion of such
a fault existing.
