legplate tester. Refer to your
monitor’s operator’s manual for
complete information.
1. Slide the legplate into the monitor’s
Legplate Tester jack and hold
firmly in place. (The legplate tester uses an internal ECG simulator
circuit for testing cable/legplate assemblies. The tester simulates a
signal of 120 BPM ± 1 BPM.)
2. Plug the other end into the
ECG connector on the transmitter. Verify
the following on the monitor:
u the corresponding FHR value reads 120 BPM;
u the corresponding FHR heartbeat indicator flashes at a rate of
120 times per minute; and
u the ECG “beep” is heard from the speaker.
