Analog Output Calibration
Analog calibration signals that allow external device calibration are
provided after initial power up, and continue until the Model 7500FO
begins tracking SpO
ends when the system begins tracking signals. The calibration signal
sequence is as follows:
26
0 - 1.0 VDC (representing 0-100%)
1.27 VDC (out of track)
0 - 1.0 VDC (representing 0-300 BPM)
1.27 VDC (out of track)
0 VDC or 1.0 VDC nominal (representing
an event).
Event marker high for SpO
