Communications tests
The following series of tests verify that the transmitter is operating properly with the
receiving system and the monitoring network. A CIC Pro center that has access to the
receiver system is required.
Verify leads
This test verifies that the transmitter can test for, and indicate, good lead signals.
1. Attach the leadwires to an ECG source and to the transmitter.
2. Install batteries in the transmitter.
3. Admit the transmitter to an available receiver at the CIC Pro center. Verify that
the ECG signals display at the CIC Pro center.
NOTE
It takes approximately 10 seconds for the transmitter to display waveforms
for a 3-lead cable.
4. Press the Verify Leads button. The Lead Status and Change Battery LEDs
flash twice to acknowledge that the button was pressed. The lead status displays
for approximately 1 minute. Lead status LEDs for good leads remain illuminated
for the time period.
5. Verify, both at the CIC Pro center and on the transmitter, Lead Status each time
with a different lead wire removed from the ECG source. The LED associated
with the disconnected leadwire should not remain illuminated and the associated
lead should show lead fail at the CIC Pro center.
NOTE
In 3-lead mode, the reference lead is always displayed as “Good” during the
“verify leads” test.
Graph request
This test verifies that pressing the Graph button results in a graph run at the assigned
printer device.
1. Configure the CIC Pro center so that graph requests (from the transmitter) are
printed at the CIC Pro center.
2. Press the Graph button. The Lead Status and Change Battery LEDs flash twice
to acknowledge that the switch was pressed.
3. Verify that a graph run occurs at the printer.
Event marker
This test verifies the Event Marker feature. This feature is available only on the
ApexPro CH and T14 transmitter.
1. Install batteries in the transmitter.
2. Press the Event Marker button.
