Checking line extension and junction box

• Use the methods described in chapters "Checking inductive conductivity sensors" and
"Instrument check by medium simulation" to perform a quick functional check from the
conductivity sensor to the measuring instrument via an extension.
• Checking the extension cable type:
– The inductive sensor only works reliably with the original CLK5 cable!
• Check junction boxes for moisture (possible influence in low conductivity range):
– Dry junction box
– Replace cover gasket
– Inspect cable glands for tightness
– Use desiccant bag
• Check junction boxes for correct line connections:
– When the prescribed original CLK5 cable is used, the cable wires (colors) are connected 1:1.
• Check junction boxes for correct outer screen connections:
– Immunity to interference is only guaranteed if the screens are connected!
• Check junction boxes for tightness of clamping screws and examine for corrosion:
– Tighten screws some time after start-up
– Replace terminals if corroded; make sure that the junction box is tight.

Service equpipment "Optoscope"

The Optoscope together with the "Scopeware" software offers the following possibilities, without
having to remove or open the transmitter and without galvanic connection to the instrument:
• Documentation of the instrument settings in conjunction with Commuwin II
• Software update by the service technician
• Upload/download a hex dump to duplicate configurations.
The Optoscope serves as an interface between the transmitter and PC / laptop. The information
exchange takes place via the optical interface on the transmitter and via an RS 232 interface on the
PC / laptop (see "Accessories").
