Installing rechargeable desiccant in the instrument
There is also a rechargeable desiccant kit available (part number L1250311).
To install rechargeable desiccant packs follow the procedure in
The instrument requires two rechargeable desiccant packs; the packs are sized to fit into the

container.
The standard kit contains two pairs of rechargeable desiccant packs. This is so you can
immediately replace the desiccant in the instrument with re-activated packs.
The desiccant packs can be re-activated by baking them in an oven at 250 °C for
approximately 8 hours. They should be cooled in a dry atmosphere. For optimum results,
re-activate the packs immediately before re-use.
