Setting the Date & Time
Data files created during measurements are coded with the
date and time the measurement was initiated. It is critical that
the date and time of the unit are correct because the unit time
stamps all measurements, and for auditing purposing, this
needs to be correct.
There are two ways to set the date and time on the analyzer:
1. Automatic time and date update:
a. Before powering up the unit, connect the unit to
the company’s internet – connected network.
The unit will automatically attempt to
synchronize with time servers on the internet.
b. Now power up unit.
c. When the unit fully starts up, on the Main
screen notice that the time and date should be
set properly.
When using the automatic time and date
function, it will use the UTC (Universal Time
Coordinated).
2. Manually set time and date: (if not plugging unit into
network)

XOS |801377-02 |Rev D |English Page 9of 22
a. Once the unit is powered up, locate the Settings
button on the left side of the screen.
b. Then select the Date & Time Button
c. Use the on-screen calendar and clock face to
change the date and time to your location and
press the “Save” button. Note: The time is in
military format (24hrs).
d. When done, select Save.
e. There will be a pop-up message confirming this
action and informing the user that the unit will
restart itself.
f. After the unit reboots itself, notice the change in
the date and time.

Operation
Starting the Instrument
After making the proper power connection:
1. Make sure that the side cover is installed properly.
2. Press the power button. The button should be
illuminated when the unit is powered on.
3. Start-up takes about one minute, during which time a
splash screen will be displayed. During this time the
unit is preparing the user interface and the user must
wait until the user interface is displayed before
proceeding with operation.
For the best measurement results it is
recommended that the unit be allowed 10
minutes of warm up time prior to taking the first
measurement.
Shutting Down the Instrument
To shut down unit:
1. Press the power button for 3 seconds or until the
screen turns black.
2. After about 30 seconds, the power button should no
longer illuminate, meaning it is safe to remove power
from the unit.
Unplugging Petra: Never unplug the 24V
power supply while the analyzer is running.
Preparing Samples
For best measurement results follow the sample preparation
procedure outlined below.
1. Swirl the sample bottle to mix contents.
2. Use canned air or compressed clean air to blow dust
particles out of the inside of the sample cup.
3. Use a new pipette to fill the sample cup more than
halfway. Not enough will cause erroneous results.
a. If using the XOS X-RF sample cups, use the
visual indicators found along the side of the
sample cup.
4. Use canned air to blow any dust particles off the film.

XOS |801377-02 |Rev D |English Page 11 of 22
5. Place the film over the sample cup and install the
sample cup’s collar. The collar has a rounded edge on
the inside; this side is the bottom. The collar should
snap into place. Avoid touching the film.
If the sample cup is prepared correctly:
•The window film is tight over the sample cup; it is not
wrinkled.
•The sample does not leak.
Improperly prepared Sample Cups
Properly prepared Sample Cup
If the sample cup is not prepared correctly discard it and start
again with a new sample cup, new film, and a new pipette.
Sample Film:
Etnom®: For the best results with the Petra
MAX, XOS recommends the use of Etnom®
sample film. This film can be reordered through
XOS (P/N 200335-02).
Mylar: For the best results with the Petra 4294,
XOS recommends the use of Mylar sample film.
This film can be reordered through XOS (P/N
200335-01).
XOS recommends that samples are not vented to reduce the
opportunities for contamination of the Petra sample system. If
your internal processes require vented samples refer to the
sample venting best practices quick start card.
With some types of samples there will be
degassing that will cause the film to bulge. As
long as there is enough sample to fill the cup
halfway, these samples can be measured
accurately in the analyzer without venting.
Completing a Measurement
1. Open sample lid and place sample in the sample
basket.
2. Close sample lid.
