Note: A lead-free solder such as SAC 305 is recommended for making repairs in this instrument. Cleaning of rosin residue is not
recommended. Most cleaning solvents tend to reactivate the rosin and spread it under components where it may cause corrosion
under humid conditions. The rosin residue, if left alone, does not exhibit these corrosive properties.

Inspection and cleaning

This section describes how to inspect for dirt and damage and how to clean the exterior of the instrument.
The instrument cover helps keep dust out of the instrument, and is needed to meet EMI and cooling requirements. The cover should be in
place when the instrument is in operation.
Inspection and cleaning, when performed regularly, may prevent the instrument from malfunctioning and enhance its reliability. Preventive
maintenance consists of visually inspecting and cleaning the instrument and using general care when operating it. How often preventive
maintenance should be performed depends on the severity of the environment in which the instrument is used. A proper time to perform
preventive maintenance is just before making any product adjustments.
Inspect and clean the instrument as often as operating conditions require.
