Meter calibration – Maintenance
Duration of
calibration validity:
8 years
Note for Test Laboratories
Directly measuring meters (U128X):
In as-delivered condition, screw terminals 2, 5 and 8 are
tightened in order to establish contact between current and
voltage inputs.
If isolated voltage supply is required for tests, the screw ter-
minals can be released (remove screw cover, release
screws, pull insulating sleeves over contact pins in the ter-
minals and connect simulator voltage).
Calibration Reading
For testing and calibration purposes the energy values can
be displayed with a higher resolution. Press the menu key,
as shown in the flowchart in chapter 4.4. Refer to chapter
4.2 for the type and feature dependant resolutions.
Maintenance
No special maintenance is required. Use a slightly damp-
ened cloth for cleaning. Avoid the use of solvents, cleansers
and abrasives.
