DEVICE SETTINGS
Device Settings determine the operating functions for the IRMA TruPoint
system.
• Non-QA Users can access and change the beeper, date format, time, printer,
and screen contrast functions.
• QA Users can access and change the above functions as well as the change
the date calibrate barometer, and communications functions.
All users can access the DEVICE SETTINGS
menu by pressing
Device from the SETTING
OPTIONS menu. To access a device setting,

CALIBRATE BAROMETER
1. Run an EQC test. When the test is completed,
compare the IRMA TruPoint barometer
reading to the reference barometer reading by
accessing DEVICE SETTINGS from the
SETTINGS OPTIONS menu.
Scroll down until Calibrate Barometer is highlighted. IRMA TruPoint's
current barometric pressure displays below the DEVICE SETTINGS
scroll box. Compare the value displayed on IRMA TruPoint to the
reference barometer. If they are the same, press
done .
2. If the barometer needs adjustment, press edit
and enter the value from the reference
barometer. IRMA TruPoint accepts values
from 350 - 900 mmHg. Save the value entered
by pressing
next .
Note:
• The IRMA TruPoint barometer was calibrated at the factory, and should
read within ± 5 mmHg of a NIST-calibrated barometer. Use of a non-
NIST traceable reference barometer to adjust the IRMA TruPoint
barometric pressure reading is not recommended.
