Voltmeter Training - Sony Playstation 2 Repair Manual

IF YOU KNOW HOW TO USE A VOLTMETER TO READ VOLTAGES AND MEASURE
Before doing some of the techniques in this manual you are going to need to know how to use a voltmeter. They
are very easy to use and it won't take long to get you up to speed even if you have never used one before. If you
don't own a voltmeter then you may need to buy one or borrow one.

Here is what my voltmeter looks like. They come in
various shapes and sizes and can be picked up at most
hardware stores or at Radio Shack. They can be very
expensive or you can get them pretty cheap. A cheap
one is all that is needed for this project. Notice that
there are two wires coming out of it. One is red and the
other black. Red is the (+) positive lead and Black is
the (-) Negative lead. None of the measurements we
will be doing are dependent on having the positive and
negative leads connected in a particular order. All of
the measurements can be taken with either lead in
either position indicated. That will make it easy for
you.
Next, we need to go over the setting on the voltmeter
that we will be using. This will vary from meter to
meter. Most of them use the same symbols and
wording so you should be able to figure it out on yours
by looking at the description and picture here. The first
setting is Ohms (See picture). This is the setting you
use to check fuses and to adjust the laser voltages. All
measurements you will be taking are less than 2000
Ohms so you will need to pick the scale that most
closely matches this setting. Many meters, like the one
shown use an auto-scaling feature. This makes it so you
don't have to worry about what scale to pick. So if you
have to buy a meter you may want to pick one up that
has this feature built in.
That's it for the voltmeter training. In each section that we use the voltmeter there will be more detailed
instructions on exactly what to do. So don't panic if you don't feel like you quite understand it yet. You will get
more details when needed.
