venTest OPERATORS MANUAL
4.12.4 IRMA™ AX+ (optional)
This menu item is used to power on the IRMA™ and perform adjustments. Note that the sensor is
connected to the RS232 connector on the back panel of the venTest, using a DB9M to DB9M
adapter cable (7200-241).
WARNING:
A voltage is applied to a pin of the RS232 socket by turning on the
IRMA™-supply voltage. Be sure that no other device is connected
to the RS232 port, otherwise the device could be damaged.
A zero adjustment is required if the sensor deviates from its zero point. The zero adjustment is
completed when the IRMA™ sensor stops flashing and the green light is on steadily. The sensor
must be attached to a Masimo multigas tubing adapter (7050-070 Adult/ped, or 7050-071 Infant)
to get any reading on the venTest.
