Disassembling the Test Tool
6.1. Introduction 6

6.1. Introduction
This section provides the required disassembling procedures. The printed circuit
assembly removed from the Test Tool must be adequately protected against damage.
The Test Tool contains static sensitive components. Handling and servicing these
components should be done only at a static free workstation by qualified personnel.
The Test Tool contains a Li-ion battery pack. Refer to the Fluke 190-104/190-204 (Fluke
190 Series II) Users Manual “Safety Information” Chapter (page 4 onwards) for
instructions how to safely handle and use this battery pack. The Users Manual can be
downloaded from Fluke’s website..
In the Test Tool 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.
At the end of this chapter a number of pictures shows the various stages of disassembling.
Warning
To avoid electric shock, disconnect test leads, probes and
power supply from any live source and from the Test Tool itself.
Always remove the battery pack before completely
disassembling the Test Tool. Only qualified personnel using
customary precautions against electric shock should work on a
disassembled unit with power on
6.2. Disassembly & Reassembly Procedures
6.2.1 Required Tools
To access all the assemblies, you need the following:
• Static-free work surface, and anti-static wrist wrap.
• #10 Torx screwdriver.
• A small screwdriver or pair of tweezers to unlock flatcables from their connector.
• Cotton gloves (to avoid contaminating the lens, and the PCA).
6.2.2 Removing the Tilt Stand, Hang Strap, and Side Strap
To separate the Tilt Stand from the Rear Case: gently bend both rotation points away
from the Rear Case (no need to remove screws or other fixing devices).
Before opening the Test Tool, you must remove the Hang Strap and the Side Strap. How
to remove and install the Hang Strap is explained in the Users Manual in Chapter ‘Tips’.
The grip of the Side Strap consists of two halves kept together with Velcro tape. After
having opened it, the straps can be taken apart and be removed from their fixing dowels
in the side of the Test Tool. Before doing this, take careful notice on the correct position
of the strap. To install work in reverse order.
