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 form analysis.
