Status Indicator
The STATUS indicator, in the upper right corner of the standard operating screen, as shown below,
provides user feedback on the test in progress.

SIGNAL
97% 60 BPM 100%
The following STATUS messages may be displayed:
NO SIGNAL
No optical signal is currently being received by
Oxitest Plus 7
from the
oximeter under test. Possibly the oximeter sensor has not been applied to the
Oxitest Plus 7
probe.
Testing...
Oxitest Plus 7
has detected an optical signal and is testing the signal to see if it
is consistent with the selected oximeter.
NO RED
An optical signal has been detected, but there is no signal which corresponds to
the output of the RED LED. Probable sensor or cable failure.
NO IR
An optical signal has been detected, but there is no signal which corresponds to
the output of the infrared (IR) LED. Probable sensor or cable failure.
RED+IR OK
The optical signal detected by
Oxitest Plus 7
is consistent with the oximeter
selected and
Oxitest Plus 7
is outputting a simulated signal to the oximeter.
INV.SENSOR
Oxitest Plus 7
has detected an external optical signal on the upper probe
surface, indicating that the oximeter sensor has probably been applied upside
down. Remove and replace the sensor with the sensor LEDs on the
lower
surface of the
Oxitest Plus 7
probe .
If the
STATUS
message enters the
Testing...
phase and then begins to rapidly change, it is
probable that the oximeter under test is not the same make and model as the oximeter selected in
Oxitest Plus 7
. Change the
Oxitest Plus 7
Pulse Ox
selection to match the oximeter and retry
the test.
When testing some oximeters,
Oxitest Plus 7
may not, at first, correctly recognize the red and IR
light flashes produced by the oximeter. In this case,
Oxitest Plus 7
status display will show
RED+IR OK but the oximeter saturation reading will significantly disagree with the
Oxitest Plus 7
SpO
2
setting. The simplest solution is to remove the oximeter sensor from the
Oxitest Plus 7
probe, wait a few seconds, and then re-apply the sensor to
Oxitest Plus 7
. Alternatively, the
