1.
Interrupt the sample feed to the photome-
ter.
2.
Check the current measuring value in the
Meas. info
menu (carry out the mea-
surement without a sample). The measuring
value should not exceed 0.1 FNU on the
AquaScat SG and 0.5 ppb on the OilGuard
SG.
If these values are exceeded,
this may be due to a soiled
measuring cell. In this case, con-
sult the Section 9.4.2.
3.
Loosen the screw connections X and Y and
remove the inlet pipe.
4.
Remove the optics unit on the photometer
according to Section 9.4.1 and place in the
recess (docking station).
Danger due to UV radia-
tion (on OilGuard SG only).
Use UV goggles and gloves.
5.
Check whether the appropriate checking
unit is used for the photometer and that the
checking unit is clean.
(OilGuard SG only)
The checking unit must have the
same temperature as the instru-
ment. If the checking unit is
stored in another room, let the
unit acclimatize to the conditions.
6.
Mount the checking unit and fasten with the
knurled screws.
Make sure that the pins enter the position-
ing holes (arrows).
