10 Maintenance
The quality of pressure test kit measurements can only be guaranteed when the
maintenance and calibration intervals are observed. Tests under DVGW G469 (A)
and W400-2 Part 16 require annual calibration.
10.1 Calibration intervals
Union Instruments recommends calibration yearly. Union offers a calibration
service.
10.2 Replacing printer paper
Open the cover by slightly lifting the panel with a finger and pulling upward.
Thermal paper is generally only printable on one side. The thermal paper has to
be unrolled a few centimeters and inserted so the printable exterior is facing the
printing mechanism and the interior is facing the open lid. Close the cover by
pressing it down firmly until it clicks into place. The paper should now be firmly
clamped between the rollers in the cover and the printing mechanism.
NOTE
When inserting the paper roll, make sure the printable side is facing up when
unrolling.
Sand or dirt in the printer can cause the print head to fail or be damaged.
10.3 Cleaning
10.3.1 Cleaning the printer
Open the cover by slightly lifting the panel with a finger and pulling upward.
Light soiling and dust can be removed with a small brush.
Use a cotton swab soaked in isopropyl alcohol to carefully remove heavier soiling
from sensitive surfaces.
Close the cover by pressing it down firmly until it clicks into place.
