Measurement Basics at National Instruments

For an T&M Learning, Start with these tutors of NI. Like Analog Amplifier Circuits and Analog RC Filters. RF and Microwave Fundamentals if you want to be good at Communication Technologies. Sensor, DAQ and Instrument Fundamentals for Industrial Automation Learning.

Measurement Fundamentals – National Instruments

National Instruments Wi-Fi DAQ devices combine IEEE 802.11 wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI LabVIEW software for remote monitoring and control of electrical, physical, mechanical, and acoustical signals.

Measurement Basics at National Instruments

NI Wi-Fi DAQ features and to learn how you can simplify wireless remote measurements without compromising on the security or performance of a cabled data acquisition solution.

delabs Notes

You can learn about every niche/domain in Electronic Technologies. You also need to Specialize in a niche which resonates within you. The skill sets need to be broad, in case you find less opportunities in the specialization you have. This keeps changing all the time.

Android Virtual Instrumentation

Any Tablet with an external Hardware can make a nice Instrument. The professional part lies in that external hardware and usability of the software or app. Windows Virtual Instrumentation are well known. Things like USB Scope and Data Loggers have been there for decades.

Now we have Android in which an Open Source product can be developed. The Open Source is both in Hardware and Software.

Android Virtual Instrumentation

See a android virtual instrument – OsciPrime is an Open Source Android high speed data acquisition hardware platform and Android oscilloscope application.

Open Source Android Oscilloscope

Virtual Instruments for Android has a nice future in Industrial, Automotive and Measurement areas. You could start by Interfacing with Bluetooth, USB and then move to IoT and WSN.

 Android OPC UA SCADA and Client

TeslaSCADA is a SCADA for accessing production and process data through smart phones and other Android devices, using the industrial communication standard – OPC Unified Architecture (UA).

These were some questions i got a few years back…

1 – If i had to create a crude “Lux Meter” and “db Meter” using the built-in camera and microphone on a Android Device – How would i Calibrate it ?

2 – Is there a Component(software) for Android to interlace with a Arduino Device as an external interface, This will help us make a DMM/Scope or even a Entire Lab Test bench centered around a Tablet and a Plug-in Mini Instrument Rack.

Both Sound or db Meters and Lux or Light Level Meters are in the Google Play nut need calibration. All These Instrument Needs a USB/Bluetooth Sensors.

Add Bluetooth you can carry your Tablet away from the instrument probing the DUT. (Device under Test)

Utility of Testing and Troubleshooting Tools

Utility of Testing and Troubleshooting Tools : The first thing in Electrical testing is the Continuity Tester, Then we use the Neon Mains Screwdriver, Then we need an Voltmeter or an Ammeter. In electronics we need a OhmMeter and LCR meter too.

Many times we cannot carry big or expensive test instruments to the field, so we have to have a troubleshooting tool kit. Continuity testers, Logic Probes, DMM, Clamp Meters etc..

Simple Test Equipment

It also is sometimes required to build a quick jig or fixture with electronics to troubleshoot, simulate a problem or to test the reliability or aging of components and systems. Here you need to be cost effective, fast and innovative; and build a simple system with available, affordable or procurable resources. Hence a bit of circuit design, firmware and software are essential skills for production engineering.
