Nothing In Particular

I was surprised to hear that a saxaphone is a wind instrument...

Maybe a saxaphone is.

What about a saxophone though eh eh eh eh?!

Ha!

Ah, the old Grantchester trick ! - you learned well.

Heheheheheh!

PS. Shurrrups you!

Days are drawing in, Winter's on its way!

Wot - solstice on the 20th ?

Wot - solstice on the 20th ?

Yep, In the northern hemisphere, the 2020 summer solstice took place at exactly 22:43pm on Saturday 20 June.

The summer solstice occurs on June 20th, 21st or 22nd in the Northern Hemisphere.

Do better quality DMMs (digital multi-meters) have any facility to reset the zero reading when testing resistance ? To allow for varying test lead resistance.

[Ali Tait]

Yes.

Absolutely. It's called "nulling" and is used to compensate for capacitance too. My Keysight/Agilent meters can also do this on many settings to determine deltas between readings, e.g. you could measure the mains at 238.434V, press the null button, and then all subsequent readings are the deltas from that value.

Put the records all in order today finally after years of rummaging around trying to find things. Unfortunately New Order's Power Corruption and Lies cover was empty. Got no idea where the record could be. Found loads I'd forgotten about or had mislaid.

Just to be picky, better quality meters allow four wire sensing to remove the meter cables from the equation.

Ha Ha! He’ll never cough up for one of those

I think this came about because Phil asked me to measure something for him; the meter I had to hand was my old Fluke, must be at least 25yrs old and still gong strong and is fine for most scenarios I encounter, but it has no nulling capability. As the resistance I was asked to measure is only a few ohms I wasn't able to be confident of the accuracy of reading; if I touch the probes together it reads over 1ohm.

I have newer, more feature rich multimeters but they don't have the quality feel of the Fluke - maybe I should shell out for a new Fluke sometime.

2R 1% resistor https://uk.rs-online.com/web/p/through- ... s/0150638/

1.5v battery and a multimeter, put 2R resistor in series with unknown, battery across them. Measure the voltage across the two resistors, the ratio of voltages will give you the ratio of the unknown with 2 ohm. 1% should be good enough.

Cheers Nick.I maybe should've thought about it more myself before but have just lived with it - my bad.
