Setting Date and Time
6.
To modify the date and time, from the Home Screen, select the Settings icon
and then select Date or Time. Follow the prompts to input the current
date and time using 24-hour time configuration and select
7.
Customers in the United States have the option to enable Automatic Daylight
Savings Time (DST) in the Time settings. Automatic DST is disabled by default.
Automatic adjustments occur based only on US DST regulations and are not
updated according to geographic location.
Date and Time Maintenance:
• Regular quarterly maintenance is necessary to ensure date and time are
correct. The set date and time will affect the timestamp listed for subsequent
patient pupil measurements on the NPi-300 and SmartGuard. Changing the
date and time will not alter the timestamps on previous measurements.
• Immediately adjust the time after any time change if Automatic DST is disabled.

Measuring Pupils Using the NPi-300 Pupillometer
The NPi-300 provides objective pupil size and reactivity data independent of examiner – removing
variability and subjectivity. The NPi-300 expresses pupil reactivity numerically as the Neurological
Pupil index, NPi (see the Neurological Pupil index Scale below).
The Neurological Pupil index (NPi) Pupil Reactivity Assessment Scale
Measured Value*
3.0 – 4.9
< 3.0
0
*A difference in NPi between Right and Left pupils of ≥ 0.7 may also be considered an abnormal pupil reading
Taking a Bilateral Pupil Measurement
9-10.
Two components are required to initiate a bilateral
pupil measurement:
• NPi-300 Pupillometer (Ex. 9)
• Single Patient Use SmartGuard (Ex. 10)
Open a new SmartGuard. Slide the SmartGuard onto
the NPi-300 with the foam pad at the bottom (Ex. 9).
There will be an audible click when the SmartGuard is
properly positioned.
