here)

The kit contains allrequired components(click for an exploded kit), but you will need to provide a

9V alkaline battery (or 2 to 4 AAA batteries). The floppy disk is shown for size comparison only!

Second picture is Mark 2 - it is the same size as the original.

super quality. The entire item is a masterpiece. Absolutely no missing parts.

Worked first time without any problem at all. All of this I truly appreciate. Also, it

arrived only 6 days after you sent it, so evidently customs didn't open it. Thank You,

Respectfully, Fredrick Howe 2850 North County Road 1500

Niota, Illinois 62358 I must go on to tell you that I lost my job in

February at age 60. This necessitated going back into the TV repair business so I know for

certain what I'll be doing for the next 5 years or so. If I'd had an item such as this 25 years

ago, It would certainly have been a big help. After 40 years experience as an electronic tech,

this is certainly one of the ultimate tools of this trade.

(March 19, 2003)Dear John, The K7204 ESR meter kit I ordered arrived day before yesterday, and I assembled it yesterdayThis email is just to tell you how pleased I am.Excellent quality kit, perfect PCB quality, and all parts there in the box.

Worked perfectly first time, no troubleshooting required. I am a television broadcast engineer for our local government TV

station,and my hobby is restoring old audio tape recorders. I have wanted an ESRmeter for years, but locally the only unit

parts distributors carry is the B& K 885/6 at over $750.00US. Way too much for a hobbyist! Thanks for making this kit

available in the North American market. I'm sending a Cc of thismessage to Bob Parker to convey my thoughts about his

meter and to thank himalso. Sincerely, G H L Miami, FL 33184-2004USA

Hey John - -

Yes, the kit arrived quickly and in perfect shape. I put it right together in about 5 hours and it worked

perfectly the first time I turned it on. I really like it - - very accurate after calibration with the very accurate

cal resistors. I use it to see that my ham antenna is making good contact through the joints to each element

as well as a check on the state of computer power supplies. You can measure the ESR of the computer

outputfilters by probing the contacts of the big connector that plugs into the mother board (after unplugging it and

all the drives that also use power).

It's worth keeping track of these ESR readings every 6 months or so to keep from having hard drive failure

due to power supply problems. I also use it to check the ESR of Zener regulators and newly charged AA

and AAA cells. I took about a week to look at all the ESR circuits on the web and competing

ESR Meters. Yours stood out strongly from the rest with the 99 + 90 + 90 = 279 reading resolution of the

three ranges, the zeroing, and the auto turn-off feature. I preferred it to the EVB design out of Portugal

because

of its stronger case, larger battery and no input protection diodes on the PCB (I'd rather add themexternally).

I'm completely satisfied with my purchase and happy with its performance. Thanks for following up - -
