Maintenance
Introduction
Because this is a high-performance instrument, Fluke Calibration does not
recommend that the Product be repaired to the component level. It is easy to
introduce a subtle long-term stability problem by handling the circuit boards.
Access procedures are provided for those who want to replace a faulty module
only.
Clean the Exterior
To keep the Product looking like new, clean the case, front panel keys, and lens
using a soft cloth slightly dampened with water or a non-abrasive mild cleaning
solution that does not harm plastics.

Caution
Do not use aromatic hydrocarbons or chlorinated solvents for
cleaning. They can damage the plastic materials used in the
Product.
