Revision D
APEX Telemetry Transmitter
3-13
401566-166
Pause Alarm
This test verifies that the transmitter enters into the PAUSE ALARMS
condition for approximately five minutes.
1.
With the transmitter operating, press the GRAPH and VERIFY
LEADS buttons simultaneously. The LEAD STATUS and CHANGE
BATTERY LEDs should flash twice to acknowledge the switch was
pressed.
2.
Once the transmitter enters the PAUSE ALARMS condition the
PAUSE ALARMS LED begins flashing, and flashes for the
programmed period. (Typically five minutes but this value can be
changed by reprogramming the transmitter.)
3.
At the end of the period the PAUSE ALARMS LED should stop
flashing.
4.
Test termination of the PAUSE ALARMS condition by pressing the
VERIFY LEADS and GRAPH buttons simultaneously. Once the
PAUSE ALARMS LED begins flashing, press the VERIFY LEADS
and GRAPH buttons again. The PAUSE ALARMS LED should cease
flashing.
Pacemaker Transmission
This test verifies detection of a pace pulse and transmission to the
central station display.
1.
Connect an ECG simulator to the transmitter.
2.
With the transmitter operating and ECG waveforms from the
transmitter being displayed on the central station, trigger a pace
pulse at the ECG simulator.
3.
Verify a pace mark on the central station. (Ensure that the PACE
function is enabled on the central station.)
ECG Waveform
Transmission
This test measures the gain through the transmitter/receiver system.
1.
Connect the ECG simulator to the transmitter.
2.
Verify that ECG signals from the transmitter are being displayed on
the central station.
3.
Verify the ECG gain at the central station is set to 1X.
4.
Trigger a Graph run at the transmitter.
5.
Measure the graph output. Signal level should be 1 cm (two large
boxes on graph strip) for a 1 mV input.
