Introduction; Disassembly & Reassembly Procedures; Required Tools; Removing The Tilt Stand, Hang Strap, And Side Strap - Fluke 435-II Service Manual

6.1. Introduction

This section provides the required disassembling procedures. The printed circuit
assembly removed from the Analyzer must be adequately protected against damage.
The Analyzer contains static sensitive components. Handling and servicing these
components should be done only at a static free workstation by qualified personnel.
The Analyzer contains a Li-ion battery pack. Refer to the Fluke 434-II/435-II/437-II
(Series II ) Users Manual 'Safety Information' Chapter (page 1-7 onwards) for
instructions how to safely handle and use this battery pack. The Users Manual can be
downloaded from Fluke's website.
In the Analyzer a number of selftapping screws are used. When mounting these screws
again it is advised to use a hand-operated screwdriver and reisert them into the 'tracks'
already present in the plastic. This assures a longer life of the plastic parts of the housing.
At the end of this chapter a number of pictures shows the various stages of
disassembling.
To avoid electric shock, disconnect test leads, probes and
power supply from any live source and from the Analyzer itself.
Always remove the battery pack before completely
disassembling the Analyzer. Only qualified personnel using
customary precautions against electric shock should work on a
disassembled unit with power on.
Important: the Analyzer has a battery door that is fixed with 2 quarter turn screws.
Behind the door are located the Li-ion battery and the SD memory card.
If the SD card is not installed, only momentary measurements such as a meter screen can
be done. Measurements over time such as Monitor or trend are not possible then.
If the battery is not installed the Analyzer can work on the Power Adapter BC430. The
battery itself is provided with a 'Fuel Gauge' LCD display with 5 segments each
representing about 20 % of the battery's total capacity.
The battery door has optical detection device that prevents the Analyzer from starting up
if the door is not closed.
