TWINTEX TFG-3620E Review

Twintex Instrument Ltd was established in 1998 as a professional test & measurement instruments manufacturer based in China & Taiwan.

Thanks to Miss Lily Cheung Sales manager, one TFG-3620E arbitrary waveform function generator arrived end of September for a product review.  

The TFG-3600E series are the affordable product range of Twintex, and comes loaded  with most functions, frequency's counter up to 200 MHz & RS-232 communication port

GW Instek GDS-320 Oscilloscope & GDP-040D Review

Oscilloscope & multimeter , touch screen , with option differential probe 600V RMS

In Taitronics 2014 GW Instek walked away with the gold award of innovation due their GDS-200 & GDS-300 series.
Today ITTSB with pride announcing the product review of GDS-320 that is the leading model regarding bandwidth as Oscilloscope, and also regarding counts as multimeter.  

Sexy & Beyond is the marketing logo of this product series which is correlated with the promotion video of GW Instek about the specific advertising campaign.
ITTSB shown significant interest to receive and evaluate one sample of this new pack of innovation, the main question is how GDS-320 measure-up in applications which an industrial electrician gets involved with?
I like to thanks GW Instek for accepting this challenge regarding the product review, and about donating both equipment GDS-320 and GDP-040P, the second is the differential probe option which offer the ability to GDS-200 & 300 Series about single phase, and phase to phase electrical measurements up to 600V RMS in Oscilloscope mode.
GDS-300 Series is not a usual DSO in a small package, there is one significant amount of software applications inside this equipment which using the hardware as multimeter or as Oscilloscope in many ways, and this makes possible even complex electrical measurements.
GW Instek due these software applications for GDS-300 has the flexibility to expand the potentials regarding new software applications even further.
ITTSB suggested to GW Instek R&D team the creation of another one software application which will expand GDS-300 potentials as Watt meter too.

My personal viewpoints, comments, News.

Safe 220V & 380V measurements with a bench top Oscilloscope by using one differential probe.

The Bottom line is that you can not avoid paying the price for a true differential probe if what you have in mind is work instead play.

Intro:

I am now an 45 years old electrician, and today I am able to see the Mains voltage and measure its and every parameter.

Never thought that my first class oscilloscope with the differential probe hooked up, that has so much to offer.

Four Industrial handheld multimeter's tested above the 1000 ACV mark.

Monday 1 February 2016

ITTSB Blog up to date this performed many individual reviews of handheld multimeter, this latest benchmark has to do with the performance of four full size multimeter's when them get tested out of their measuring specifications’ that is above the 1000 ACV range.


Few months back I started thinking to build for my lab one amplifier which this in combination with a function generator, it will work as adjustable ACV source …….

I am very pleased to announce a new marketing cooperation of ITTSB Blog and APC by Schneider Electric, and more specifically with Mr. George Dritsanos Director of North East Marketing division (based in Serbia).
APC by Schneider Electric in Greece and their director of sales Mr. Tasos Sarris among with Thalia Serekla (PR) manager. They both helped so one sample unit of latest APC-SMC1500I this to arrive for a product review.

HIOKI RM3542A this is newest Resistance Meter for precision work.
ITTSB Blog proudly presents pictures of HIOKI RM3542A. This is not a regular resistance meter, primary use this is for resistors precision verification at production line .
RM3542A arrived at ITTSB Blog so this to serve in a special project, I am going to upgrade all resistors of my decade resistor box with product samples from Vishay Foil resistors (VPG) all  secondary standards class.
ITTSB goal this is evaluation of up to 7 ½ bench top multimeter in the near future.

Special thanks to HIOKI EE Corporation and to Michelle Uchiyama Marketing Manager, for all battles that she gave so my proposal for RM3542A Resistance Meter this to gain approval.
Special thanks to M.J  PRINIOTAKIS S.A.I.C in Greece, Test and measurement division and HIOKI authorized reseller.  Katerina Priniotaki - Managing Director, she helped by importing RM3542A at no cost for ITTSB Blog.

New in 2017 - Consumption Evaluation & Power Quality:
Basic Power Analysis test bed | Power measurements | Inverters testing  
Product reviews and evaluation of measuring tools this is one side of the coin.
True purpose of any electrical measuring tool this is delivery of reliable measurements’ in tasks relative to basic power analysis.

Power quality inspection and testing of individual electrical appliances consumption, these are both new challenges for every active electrician of our times.
Basic power analysis this is a job for good multimeter and clamp on meter and naturally of high performance oscilloscopes.

ITTSB Blog this started getting prepared to conduct product reviews of ups and inverters, such a test lab this requiring special tools and as such are adjustable ACV input source 0~270 Volts,  ACV loads among with Single Phase Voltage and Current Breakout Box.

I did follow the route of DIY electrical engineering and test tools assembly in my own workbench.
Regarding bill of materials and cost estimates, I did follow most cost effective path but even so by using exclusively highest quality of parts them complying to most recent IEC directives’.
Today they are scheduled two DIY projects, and links and pictures will be added at this Blog sector.

I like to thanks DER EE ELECTRICAL METER CO. LTD. in Taiwan for their sponsoring of all necessary analog meters for those too ITTSB Blog projects’.
