First reviews of 2018

Thanks for your continued patience, everyone. Following on from my little mishap in December, which has effectively prevented me from blogging or making YouTube videos from mid-December onward, I plan to start doing some blog writing with more detailed blogs and videos to follow perhaps in April/May when I’ll also have access to all my electronics gear following house moving. Our original plans which included spending the entire summer in Spain, came adrift mid-December.

For now I’m doing my best to respond to your emails and looking to doing some short equipment write-ups. I have some catching up to do on the writing front. At least now I have a computer with camera up and running.

Here is a start on some of the stuff that arrived for me while I was out of action.

UNI-T UT61E 4-digit True RMS Multimeter from Banggood


Being used to run-of-the-mill 3.5 digit multi-meters, the UNI-T UT61E 4 digit True RMS Multimeter represented a move upmarket for me and the unit I received came complete with optically isolated RS232 adaptor. A USB cable is, as an alternative, available as an option on all models in the range except UT61A. I should have thought about that but I didn’t.

  1. Operating temperature range is 0c to 40c with storage range claimed to be –10c to 50c. As well as the usual AC/DC voltage and current measurements with accuracy as high as 0.5%, resistance and diode testing, the UT61E tests capacitance as well as frequency and duty cycle.

The meter comes complete with mini-CD. I did not need to use this.

Measurements can be absolute or relative to readings stored earlier. The unit also has a HOLD button and a PEAK button.

The meter uses a single 9v battery. Banggood supply this and many other measuring instruments.
