4 Maintenance
4.1 Storage
• Rinse the Spectrosense with dist. water between the titrations.
• Rinse the Spectrosense thoroughly with dist. water and dry it before
storing it.
• Use only soft tissues to wipe the mirror surface and make sure no for-
eign material is on it, as this would involve the danger of the surface
getting scratched.
4.2 Troubleshooting
Problem Remedy
There is no
output signal. • Connect the Spectrosense to the MSB connection
of your Titrando or to the stirrer connection of your
Titrino.
• Connect the Spectrosense to the measuring input
'Ind.' of your Titrando or Titrino.
• Remove the Spectrosense from the solution and
check whether there is light at the tip. If you cannot
see any light you have to replace the Spec-
trosense. The LED cannot be exchanged.
The output signal
is noisy or
unstable. • Check if the mirror is tightly screwed onto the
Spectrosense.
• Check if there are any foreign materials or air
bubbles in the optical path.
• Check whether the connection to the power supply
exists. The connection must not be under me-
chanical stress.
