Verify Graph Request

MAINTENANCE: Checkout Procedure
The following series of tests verify that the transmitter is operating
properly with the receiving system and the monitoring network. A
central station that has access to the receiver system is required.
This test verifies that the transmitter can test for, and indicate, good
lead signals.
1. Attach the leadwires to an ECG source.
2. Install batteries in the transmitter.
3. Press the VERIFY LEADS button. The Lead Status and CHANGE
BATTERY LEDs should flash twice to acknowledge the switch was
pressed.
4. The lead status is displayed for approximately 1 minute. Lead status
LEDs for good leads remain illuminated for the time period.
5. Verify by repeating several times, each time with a different lead
wire removed from the ECG source. The LED associated with the
disconnected leadwire should not remain illuminated.
NOTE
In 3-lead mode, the reference lead is displayed as "Good"
during the VERIFY LEADS test. The V lead LED does
not illuminate.
6. Configure the central station to monitor the test transmitter. Repeat
the previous steps. Verify the LEADS FAIL message is displayed.
While in 3-lead mode, the reference lead and the V lead will be shown
as lead fail.
This test verifies that pressing the GRAPH button results in a graph run
at the assigned printer device.
1. Configure the central station so that graph requests (from the
transmitter) are printed at the central station.
2. Press the GRAPH button. The Lead Status and CHANGE BATTERY
LEDs should flash twice to acknowledge that the switch was pressed.
3. Verify that a graph run occurs at the printer.
