6.
Verify that the pressure reading on the monitor is within 3 mmHg of the reading on
the digital pressure meter.
7.
Press
to start the test at
300 mmHg
. The cuff inflates to approximately 300 mmHg
and then settles to a lower pressure.
8.
Verify that the pressure reading on the monitor is within 6 mmHg of the reading on
the digital pressure meter.
9.
Press
to return to
0 mmHg
pressure.
10. Disconnect the hose from the monitor.
Radio test
This test applies only to model 802LTAN, 802LTAS, 802LTRN, and 802LTRS monitors.
1.
Locate the monitor within 10 feet (unobstructed) of an Acuity System wireless access
point.
2.
Verify that the network connection symbol
appears on the monitor.
3.
Navigate to
Service > Radio > Show Info
.
4.
Verify:
Model 802LTRN, 802LTRS
RSSI
–41 @ 10 feet
Model 802LTAN, 802LTAS
RSSI
–61 @ 10 feet
Safety test (Hi-Pot)
The monitor contains no isolation barriers.
The cradle contains two 4KV isolation barriers—one between the 17-pin connector on the
monitor and the dc power input connector on the cradle, and one between the 17-pin
connector on the monitor and the USB connector on the cradle. These barriers are fully
tested, at the factory, at 4KV rms at 60 Hz.
The power adapter also contains a 4KV isolation barrier.
Since each successive exposure to high voltage contributes to the degradation of an
isolation barrier, and since no direct mains connection to the cradle exists, the following
tests use a hi-pot voltage of 1.5KV as a reasonable compromise.
Optionally, this hi-pot test can also be done on the power adapter.
Electrical leakage tests for source and sink can also be done on the power adapter or on
the cradle as follows:
Note
The monitor might momentarily display
+++
(overrange reading) before settling
below 300 mmHg.
Note
If the connection symbol does not appear, verify that the network is up and that
the monitor has not been intentionally disconnected from the network.
If the connection symbol still does not appear, refer to
