This arrived just 8 days after ordering it (along with the LC meter I'd also ordered separately so I'd have a stream of goodies arriving in the post this December - another LCR tester, terminal blocks for the LC meter and two types of DC-DC converter modules). The kit was complete down to the last nut and bolt and a 220nF test cap. No instructions but none were needed for "a genius like wot I am" ;-) Mind you, a printed basic construction guide would have been handy. It was only after sticking the front panel sticker onto the case that it became obvious I should have pre-drilled a 4mm dia hole for the red led to shine through before sticking it down. I landed up replacing that feeble red led with a blue led and used a 1/4 inch twist drill to carefully thin out the plastic under the sticker sufficiently to achieve a visible power on indication (blue is less attenuated by the blue/green sticker material). The red led drops about 1.9v versus the 2.9v of a blue LED but wasn't a problem to the power on circuit even at the rather precise minimum of 5.50v it requires. Indeed, it helped reduce the current consumption by a couple of mA (down to circa 22mA @9v) so it's a good idea to use a blue LED, mounted as close to the underside of the front panel if you want to avoid putting a hole in the front panel sticker (just pre-drilling the case to maximise visibility of this indicator rather than having to take great care to avoid damaging the sticker when thinning out the plastic as I'd been obliged to do). I did this more for the aesthetics rather than for its function since the LCD does this job quite nicely anyway. All in all, I'm quite impressed by its performance, particularly in determining which of my collection of recovered electrolytics are worth keeping & which need to be scrapped. The quality was only let down by the lack of a hole for the power led to shine through the top cover & the rather fiddly nylon spacer arrangement for securing the board.

  • Johnny_B_Goode The image files had meaningful names when I attached them but BG's review submission system leaves a lot to be desired (as do a lot of their web submission pages). The first photo is demonstrating the indicator LED's visibility under a fairly bright desklamp (1500lm LED lamp). The second image is showing the LC-CE meter kit's worse case current consumption of 90mA whilst testing a 1000μF 6v3 electrolytic capacitor I'd recovered from a scrapped PC MoBo a few years ago. It's powered off my bench lab supply @12v but the current is pretty well constant over the range of 7 to 15 volts anyway.

    The image quality is better than you see on the web page when you open the slide show and right click select copy to a local folder. I tested this on the first image and got a 738.5KB png image download (versus the original 1.1MB jpg image I'd submitted).

    Drilling a hole (4 or 5 mm diameter) BEFORE putting the sticker in place should give a more highly defined bright blue spot if you replace the original red LED with a blue one which will be less attenuated by the blue/green sticker. Although it's not essential, it can help diagnose a display problem should the backlight fail for any reason in the future.
