OXITEST PLUS 7 OPERATING MANUAL
4. To allow the oximeter under test to stabilize to the "abnormal patient" simulation, a delay of 5
seconds is introduced at this point, as shown above.
5. After this delay, the alarm test automatically resets the SpO
2
to the "normal patient" level
(97%). The timer is automatically reset to zero at this point and begins counting up again:
LOW SAT ALM T: 00.1
97% 72 BPM 100%
6. When the oximeter alarm shuts off, the user presses
Start/Stop
for the third time. This stops
the timer, and records the alarm OFF TIME in the
Oxitest Plus 7
memory. The LCD
automatically displays the final test results as follows:
ALARM ON: 15.8 sec
ALARM OFF: 7.3 sec
Pressing any key except
Alarm Test
at this point will exit the Alarm Test Mode. Pressing
Alarm
Test
with the LCD in the state shown above causes the display to return to the state shown in
step (1.).
The HI RATE, LO RATE and LOW SIG tests operate in a similar manner to the above, except that
the tester heart rate (HI/LO RATE), pulse amplitude (LOW SIG), or motion artifact (ARTFACT)
is varied accordingly, with the remaining test parameters left constant.
The Alarm Test Mode exits to the Manual Mode if any key other than
Alarm Test
or
Start/Stop
is
pressed. This will also abort an alarm test which is in progress. When exiting the Alarm Test Mode,
the test parameters are set to default values of 97% SpO
2
, 60 BPM heart rate, and 100% pulse
amplitude.
The parameters of the Alarm Test Mode may be programmed to alternative values via the RS-232
port, using the
OxiEdit
software which is available at www.datrend.com.
The factory default Alarm Test parameters can be reloaded by powering up the unit while holding
down the
Alarm Test
key. In response to the LCD prompt, press the
Yes
(Pass) key to reload the
test default test settings, or
No
(Fail) to abort the reload.
