OXITEST PLUS 7 OPERATING MANUAL
Figure 6 - Nellcor DS-100A finger clip sensor
With the oximeter turned ON, hold the sensor in the open position, with the LEDs (they should
be glowing red) shining toward you - the photo detector will be closest to you, hidden by the
hard sensor shell. Place the photo detector on the
Oxitest Plus 7
probe, with the end of the
probe touching the ‘end stop’. Allow the sensor to close around the test probe, keeping intimate
contact on the upper, photodetector side.
It is important to retain the tight, intimate contact
on the photodetector side to prevent leakage of light from the sensor LEDs on the
bottom reaching the photodetector on the top.
Most finger clip sensors are configured such that, when applied to the test probe, the cable will
lead off
toward
the
Oxitest Plus 7
. In this case, the sensor cable should be routed via the probe
compartment so that the cable leads off toward the the “LCD end” of
Oxitest Plus 7
, rather
than toward the bottom of the tester. The
Oxitest Plus 7
probe incorporates a cutout designed
to accommodate stiff or long strain reliefs found on some oximeter cables. This helps prevent
stiff cables from inadvertently pushing the sensor off the probe. Stiff cables or long strain reliefs
can be pre-formed to the desired shape before application to the probe.
