Thanks for checking those voltages for me and I agree with you, they are close enough. It looks as if the MAX134 is the guilty part after all. Soon find out now hopefully, it wont take long for the new one to arrive.
I've got my eye on some more matching gear to hopefully join it
I've discovered that the 8840A is not the best meter to go poking about inside it checking voltages as the input impedance is so high that if the measure the higher voltage first (in this case, 1.22V), it struggles to read the lower voltage afterwards and takes a long time for the voltage to decay, whereas the Brymen works perfectly
You're welcome.
Yeah, you kind of have to get in the habit of shorting the leads between measurements with the 8840
Maybe I should have powered up the 7075 for some more unnecessary decimal places...
Got 4 items I'm gonna get overbid on, almost certainly
A parts only 7150, which is already at £21 + £11,
That Thandar baby scope is at £31 +£9 and will probably take off in the dying seconds, wouldn't surprise me if it went over £100
Those Premas are already at £53 + £11,
And a Heathkit cap tester with 3 bidders now and 4 days to go... no chance...
I'm happy with my fairly basic Logitech wireless kb/mouse set. If I ever need it to weigh more, I'll just glue some lead to the bottom of it!
Yep, agree with the need to get into a habit of shorting the leads on the 8840A and also on the 88422A but TBH is something I'd rather not have to do when poking live circuits, particularly when poking chip pins when a slip between pins has the potential to ruin your day
That parts only 7150 is also in my watch list, only because I already have 2, but I need a handle for one of them and the one that we are both watching does not have a handle so is of less interest to me, TBH I was only watching it because I have a bit of knowledge of them now and have some brilliant white LEDs for the display and @£21 plus P&P is already to expensive, especially when it will also need a new Schaefer filter plus what ever to bring it back to life.
The Thandar, will I'm sure get into the £100 mark, Heathkit too will go far higher unless your very lucky and those Prema's will also head upwards a lot more yet I think, don't forget that they are 6.5 and not 5.5 digit displays.
But fear not, I'm not going to be bidding on any off them as they are already too pricey for my liking and I have way to many meters for my own good already.
