ITTSB Mini Articles

My personal viewpoints, comments, News.

28 May 2014

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.


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.  


My first FLUKE 87V meter mini adventure (8-2010)

FLUKE 87V GSM issue

Burn in of OLED's is a known problem (8-2012)




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 …….

Multimeter them getting constantly improved because ITTSB Blog it does record engineering innovations and even past made mistakes.   

   Bench-top Tool Reviews:  PCB Soldering - Desoldering, Battery Maintenance, and more…    


                                       First look of fresh products with innovative features.       

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.

Two samples of latest distributed precision equipment from Times Electronics UK. High build quality and performance this is what you get for your money.

HIOKI RM3542A this is newest Resistance Meter for precision work.
POWERTRON GST4020 ITTSB project 2017
Its one measurement of single electrical parameter and this made with precision, this brings us closer to the ultimate goal that is power analysis results that we can trust.

Power quality inspection and testing of individual electrical appliances consumption, these are both new challenges for every active electrician of our times.
Basic power parameters 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,  ACA 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’.

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

DER EE DE-5004 , scheduled review 2018

DE-5003 & DE5004 are 2015 released products which combining for a first time worldwide, a multimeter and an LCR bridge in the same package.

Definably DER EE Electrical ltd in Taiwan worth the title, of a company which offers innovation even within 2015.

Multimeter with LCR capabilities

DER EE DE-5203  multimeter Review

DER EE released end of 2014 in Taitronics two New series of multimeter.

DE-5203 is an 22.000 counts aiming clearly industrial electricians and more specifically applications involving latest electrical motors.

BRYMEN BM878 DMM &  insulation resistance scheduled review in 2018

BRYMEN welcomes 2015 with one additional product Series which was missing from their product line. BM870 Series is the combination of a fully featured multimeter with the needed functionality for insulation measurements. ITTSB will review BM878 model which combines most features for an industrial electrician.

ITTSB Blog in past seven months this worked hard to make happen of three projects all relative to latest high technology resistors.
Two projects are relative to Ultra High precision resistors and third this is relative to high precision & High voltage resistors.
Vishay Foil Resistors kindly offered 62  of  Ultra-High precision resistors at tightest tolerance specifications. Product series: S104K, VHP101, VHP202, VHP203, all encapsulated to metal shields for prolonged stability, and also several samples of High Value Thick Film Resistance Elements POWERTRON GST4020 series, Resistance Tolerances to ± 0.25%, TCR’s to ±25 ppm/K, them able to handle 4000 ACV

HIOKI E.E. Corporation also accepted ITTSB Blog proposal for a common presentation of their RM3542A this is Ultra-High precision resistance meter.

My presentations are written in a style this serving simplicity of understanding,  and due text and pictures my readers to feel few steps closer to this world named as industry of precision electronics.

ITTSB  Blog this now increases it ability to high precision testing thanks to
I have to admit that when I started my Blog I could not predict of how close I will come one day to best industries of our days.
This demonstration of trust in my name and at ITTSB Blog, it does load me with additional internal strength so to keep exploring and write content for this wonderful world of electrical measurements.

Personally I worked hard so the outcome of all three projects bellow, this to be of high quality. Practically this is a demonstration of what good skills can do by the use of Ultra-High precision parts among with high class measuring equipments.

   Now feel free to selects your next destination in the world
