Maintenance/Calibration
A.
Calibration
Calibration is initially performed at XIA, prior to shipment, and should be considered valid for up to a
year. To ensure that your UltraLo-1800 continues to perform optimally over an extended period, XIA
recommends enrolling in the Compliance/Calibration program. This program will verify that your system
is producing results that conform to and comply with industry standards.
If you suspect that your UltraLo-1800 needs calibration, or are interested in learning more about the
Compliance/Calibration program, please contact XIA at
B.
Weekly Maintenance
There is not much maintenance needed on a weekly basis. We recommend that you regularly check
) to familiarize yourself with the noise environment, so that if a
change in the noise environment occurs it can be caught quickly.
C.
Monthly Maintenance
There are only a few maintenance steps needed per month. Cleaning the tray, or any tray liner,
regularly (using the method outlined in
) is highly recommended. This will help keep
the background in the detector as low as possible. (If you change samples often you may want to do this
more frequently than once a month.)
In addition, doing a run with a standard sample of your choosing to ensure that your background
hasn’t changed is also good practice.
D.
Annual Maintenance
One annual maintenance step is to inspect and grease the seal around the door. To do this open the
motor dialog and run the tray out. When door gets all the way down to the bottom, press “hard stop”.
Lightly grease the seal using a silicone lubricant, either using your finger or some appropriate tool. Once
it is greased, tell the motor control dialog to continue ejecting the tray. Once it is ejected push it back in
and close it, either through the dialog or the tray control button.
The second annual maintenance item is to check
the air level of the inflatable vibration-dampening
feet and fill them, if necessary. There should be
about 3/8” space between the top of the foot and
the bottom of the counter, and the top of the foot
should be level and without bulges or divots. The
feet can be filled with a standard bicycle or car tire
pump. Be careful not to overfill, as this can damage
the foot. If you add too much air you can bleed some
out by pressing the metal pin at the center of the
valve with a fingernail or a small screwdriver.
V-1: Correctly inflated feet, finger for scale.
