Tips and Maintenance
Introduction
This chapter covers basic maintenance procedures that can be performed by the user. For
complete service, disassembly, repair, and calibration information, see the Service
Manual. You will find the part number of the Service Manual in section ‘Parts and
Accessories’ in this chapter.
Cleaning the Analyzer and its Accessories
Clean the Analyzer and accessories with a damp cloth and a mild soap. Do not use
abrasives, solvents, or alcohol. These may damage the text.
Additional to this it is recommended to open the jaws of the Current Clamp and to wipe
the magnetic pole pieces with a lightly oiled cloth. This in order to avoid rust or corrosion
to form on the magnetic poles.
Storing the Analyzer
Before storing the Analyzer for an extended period of time, fully charge the NiMH
battery.
Keeping the Battery in Good Condition
When the Analyzer is powered by the battery, the battery condition symbol in the screen
header informs you about the charge condition. This symbol ranges from fully charged to
empty:
To keep the battery in optimal condition, you must let it discharge fully and then charge
it. A full charge takes 4 hours with the Analyzer turned off. Repeat this at least twice a
year.
Installation of Options in Fluke 433
The Advanced Functions Interharmonics, Transients, Energy Usage, Inrush Currents, and
extra memory as available in Fluke 434, can be activated in an existing Fluke 433.
