6. Maintenance
6.1 Check exhaust gas sampling hoses
All of the hose lines must be handled carefully and
checked before use. Hoses are to be replaced if check-
ing reveals the following damage:
R Cracks, brittle areas, abrasion or blistering of the
hose jacket
R Kinked exhaust gas sampling hose
R Stiff union nuts or quick-release couplings
R Deformed or damaged connection end of hose line
(sealing cone, plug-in nipple, etc.)
R Leakage at hose fixture
R Corrosion at hose fixture if strength is reduced as a
result
! Damaged exhaust gas sampling hose lines must not
be repaired.
6.2 Calibrating the scale 0986610838
i The weight 0986610839 must be used to calibrate
the scale.
Procedure:
1. Use <ON/TARE> to switch on the scale.
2. Press and hold <OFF> until the display shows CAL.
3. Release <OFF>. The display will show the value of
the required balance weight.
4. Place the balance weight 0986610839 on the cen-
ter of the plate.
5. The display will briefly show F. Then, the scale will
switch off.
6. Remove the balance weight 0986610839 from the
plate.
" The calibration will be complete, and the scale will be
ready for operation again.
i In case of a calibration error or incorrect balance wight,
E will appear on the display. Repeat calibration.
6.3 Check weight 0 986 610 839
Have the weight checked every two years by a recog-
nized workshop.
