Aquisitions seem to run in similar cycles round here - I also recently stocked up on Type K thermocouples!
And good luck with that Hioki! I came close to add a very much desired Siemens U-I-Functionmeter B1080 to my repair queue yesterday, but was outbid. It seemed to have some sort of power problem, which might have worked out ok.
BTW - don't all robots go by 'Robert'?
The K type probe actually ended up costing nothing (so far*), the seller noticed the parcel hadn't moved since it was collected and after having a complaint from someone else with the same problem, they opened a claim with Ervi and refunded me, they said not to bother contacting them if it arrived and to keep it.
*Well it looks like I need to buy more TE, none of my handheld DMMs have a temperature measurement function
, all my DMMs are in the post linked below.
https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg3589932/#msg3589932Not heard of the B1080 and google search isn't helping much, can't find much for the Hioki 8220, even the Hioki website has nothing except a Megohmmeter that has recycled the model number, bit like HP with their computer/printer carp using the same numbers.
It dates from the mid 90s and having read the instructions, the only way of getting the logged data off the meter is to use a printer, the Centronics cable was included.
I've had a quick look inside.
An overall view of the mainboard, with data back-up cell (probably very dead), underneath is the switch/button board.
One of the two input channels, with some of those expensive fuses, quite a few HP optocouplers used for each channel.
Power supply section using Maxim buck regulator and the step-up supply for the CFL display backlight. Not sure about these
Panasonic Panapissy capacitors type HFQ, the type HF in stuff at work are a change on sight component for me, seen far too many incontinent ones, all dating from the early 90s.
Can't see much of the display board, the AA leaktube compartment fits in the space here.
P.S. triggered the google Robert
random event again
, now got 216 ICs listed, 141 different types, sorted the LibreOffice calc sort problem, had a column that I started listing just the numbers, than formated the column to text. The sort function ignored this & though some were text & some numbers, typing the ones it thought were numbers in again sorted it.
