Fiber Optic Cable Extensions; Calibration In Open Laboratory Vessels - Mettler Toledo InPro 8000-Serie Bedienungsanleitung

InPro 8000 Series
Note: Do not use any tools for tightening SMA to transmitter. Using tools
could cause irreversible damage to the threads. Hand tightening is sufficient.
Note: Fiber optic cables are fragile. Do no bend the fiber optic cables.
Refer to M800 transmitter instruction manual for transmitter wall mounted/
pipe mounted installation.

Fiber optic cable extensions

Fiber optic cables are available according to the list in chapter 7.2
"Accessories". The duplex cable extensions are supplied complete with four
fitted SMA plugs and two couplings. The two SMA plugs of the sensor fixed
cable are to be screwed hand-tight onto the couplings. Two SMA plugs of
the extension cable can then also be screwed by hand onto the couplings
in any order. To protect the cable connection from dust and splashwater,
it is recommended to use the METTLER TOLEDO Connection Box IP 65
(Nema 4X) (order no. 52 800 241).
If extension cables are installed subsequently at a later date, the
measuring system has to be newly calibrated (see instruction manual for the
METTLER TOLEDO Transmitters M800 1-channel, chapter: "Calibration").

Calibration in open laboratory vessels

The sensor must be calibrated during first start-up. Multi-point/Process/
in-Situ calibration are available on M800 1-channel transmitter. Recali-
bration is required when installing a new sensor/extension cables are
installed. Refer to M800 transmitter instruction manual for sensor calibration
procedures.
If the turbidity measuring system is calibrated off-line, it is
recommended to use the METTLER TOLEDO calibration tool, CaliCap™
(order no. 52 800 210), for fitting on the sensor shaft. If CaliCap is not
used, a minimum distance of 10 cm (4") to the vessel walls has to be
observed as well. During calibration, the sample should be stirred in order
to prevent the sedimentation of solid particles. Avoid direct sun light/exposing
the sensor end (nose) to direct light.
