This is a "how-to"
analog dual-trace lab scope training manual covering the procedures
to set-up and operate an analog dual-trace lab scope to troubleshoot
the circuits of automotive electrical, automotive electronic
and truck electrical and truck electronic circuits. This is also
a great first manual for technicians to learn lab scope terminology
and how to use a dual trace lab scope in auto electronics
and truck electronics repair.
Although this lab scope manual
is based on an analog lab scope rather than a DSO (Digital -
Storage - Oscilloscope) it has a lot of value explaining lab
scopes controls, terminology and wave form analysis. Chapters
cover all aspects of using a dual-trace lab scope with emphasis
on how to analyze circuit wave forms.
Dual-trace lab scopes have been
used in the electronics industry since the 1920's and now are
finding new applications in auto electrical troubleshooting,
auto electrical repair, auto electronic repair and driveability
diagnosis. A dual trace lab scope is the ultimate troubleshooting
tool for vehicle electrical repair and vehicle electronic repair.
Once you learn to use a lab scope and realize its benefits you
will wonder how you ever got along without one.
Veejer Enterprises' dual trace
lab scope training manual covers all aspects of using a dual
trace analog lab scope with detailed explanations on lab scope
terminology, function of front panel controls and how to set-up
an analog dual trace lab scope to perform a variety of critical
auto and truck circuit measurements. Sections are devoted to
the subjects of lab scope terminology, dual trace lab scope front
panel controls, dual trace lab scope set-up procedures for DC
voltage measurements for amplitude and electrical noise, AC voltage
measurements and digital signal measurements including duty cycle
wave forms. Section 7 is devoted to practice in analyzing wave
forms and detecting when a misadjusted lab scope control may
be the reason a wave form appears incorrect on the CRT but is
correct in the circuit.
The last section (Section 8)
has been added to the scope manual covering current ramping techniques.
A new updated version, Version 2003 is now available with minor
revisions and updates on duty cycle. A wave form record sheet
is provided so that you can build your own wave form record library
covering the vehicles you work on the most. Even if you are using
a digital lab scope exclusively, you will find helpful information
in version 2003 in understanding lab scope terminology and wave
