Maintenance Procedures

Replacing the reference probe capillary (LockSpray

source)

Replace the reference probe capillary if it becomes blocked, and you cannot

clear it, or if it becomes contaminated or damaged.
When replacing the reference probe capillary, you can also replace the

microfilter. The microfilter is provided, with manufacturer’s instructions for

fitting it, in the spares kit for the reference probe assembly.

Removing the existing capillary
