Test and Measurement Instruments

• Build a DMM or digital multi meter
• Small Electronic Testing Tools
  
• Measureall - Test & Measuring Instrument
• Test & Measurement Instruments
• Insulation Tester.
  
• Simple Test Equipment.
• Instrumentation and Measurement Circuits

Test Measurement and Test jigs:

Test Tools are needed for Troubleshooting and Repairing Electronic Gadgets, Equipment, Electrical Panels and Machines. Precision Instruments are required for calibration of field and machine control electronics. These are also required by the R&D engineer for design and development of new products and trying out new concepts.

In Production testing, Production Engineering, Quality Assurance QA-QC etc. You need to build Test Jigs, Configure Automated Testing depending on the size of project or budget allocated; yet it has to be made flexible, scalable and modular. These require instruments or blocks that can be adapted and reconfigured or even interface with a computing network for automated testing, reporting and analysis.

• Current Source mA for calibration
• Auto ranging 4-1/2 Digit Digital Voltmeter
• 3-1/2 Digit ICL7107 Digital Panel Meter 

Test and Measurement Instruments designed by delabs in the 90s.

Special Electronics come with every tool or gadget these days, A Slide calipers has a LCD display, Digital Readouts on mechanical instruments can help measure even sub-microns easily.  Analytical and  Chemical Instrumentation is another specialized niche. Then we have medical instrumentation which is more demanding in quality and requires sensors that are small, very sensitive and safe.

Instrumentation goes into all these and beyond. The day we find water on mars, It is only because of a precision instrument at the helm of things.

Circuits you need for scaling an analog DC value.

• Precision Amplifier with Digital Control
• Precision Attenuator with Digital Control

Analytical Instrumentation Technologies

Let us assume Physics, Chemistry and Biology as Verticals on a Horizontal plane called Science. A part of Physics developed into Magnetism and Electricity, which further evolved into Electrical Engineering a Technology. When a branch of Science is applied to develop, evolve and maintain Life on this Planet it becomes a Technology. Electrical Engineering as a Technology has evolved and branched out into many specialized domains. With the coming of Semiconductors and the Advancements of Material Technologies, Electronics Engineering emerged as a foundation or a Horizontal for many new Verticals.

One such Vertical is Instrumentation, here you know Industrial Process Control is one and the other is Test and Measurement. The third branch we learn about today is "Analytical Instrumentation Technologies" which is more like an Oblique, it Cuts thru Physics, Chemistry and Biology and many of its sub-branches. It also supports the areas called Life Sciences, Bio Technology, GeoSciences, Materials Science etc. Analytical instruments ...
