Calibration of an analog recording system
The analog output signals can be used for the calibration of any analog recording system
(e.g. polysomnograph in sleep labs).The analog outputs on the System Connector are set
to full scale of 5V (+/- 15mV) during the system check.
To perform a system check:Press both
and
when no parameter setting is in
progress (see section 10.2).
The analog outputs are set to "zero" when the connected sensor is placed into the calibration
chamber (no PCO
value is displayed.)
