Just learning the ropes

[Panasonic]

Hi everyone,
While this may seen very obvious to many, my math is not brilliant to say the least, and have a lot to learn.

While reading some electronic test procedures the information advised that while testing resistance in a circuit, the manufacturer advised that a resistance greater than 500 kOhm should be recorded.

Using a digital ohmmeter the said circuit recorded a value of 1.065 kOhm.

My question is, how should I read it?

Is it, 500 thousand ohms and 1 thousand and 65 ohms or something else?

Thanks

Is the digital meter an 'auto-ranging' meter?
Or do you have to manually set the range?
What are you testing?
Some items MUST be tested after removal from the circuit.

1.065 kOhm appears to simply be a hair over 1 thousand ohms.

Yes

 

[davenn]

Yes

no

how on earth did you come by that ?

1.065 k Ohms assuming that is supposed to be a decimal point and not a comma

its 1.065k ( 1kΩ round figures) there's no indication of an extra 500k Ω

Yes

Yes John, you are correct.

The OP asked how to read 500kΩ. He said is it read '500 thousand Ohms'.

You should get some resistors 100k 220k 470k 1M and see what is produced on the screen.
Then you will be able to measure something UNKNOWN.

The OP seemed to be asking how to interpret 1.065 kOhms on the meter they own.
It's not as clear as it could be though...

100% Agree with this though. Measuring something... almost anything that you do know will help you measure something you don't.


A digital multi-meter would need to be set to the 2000kΩ setting if it were not 'auto-ranging' .. at which case 1065 would mean 1062kΩ which is twice the minimum reading you manual has stated. A decimal should not be present at this range, and at this setting you can read up to 1999kΩ before the meter will show 'OL' which indicates that you should be using the next higher setting.

Maybe I have a slight advantage because I share his flag.

He mentioned the manufacturer as quoting 500kOhms, Then at the bottom asked if 500kOhms is the same as 500 thousand Ohms.
And his meter read 1.065kOhms and then at the bottom he asks if this is the same as 1 thousand and 65 Ohms.

Seems pretty clear to another Brit!

... Now I feel like the dumb one
You are right, but watch out for the decimal point.

 

[Martaine2005]

It was definitely the flag.

 

[Tha fios agaibh]

no

1.065k is the same as 1065 ohms.
Or, 1 thousand and 65 ohms.

 

[Martaine2005]

John, davenn was talking about the extra 500kOhms.

I have hopefully explained it well enough in post 5 and 8.

Thanks Martin.
I don't know if it's because of the flag, or because you drive on the wrong side of the road.

 

[Martaine2005]

YOU drive on the wrong side of the road.

what extra 500kΩ ?? .... no you didn't ... I was even going to query your comment last nite
but ran out of time

 

[Martaine2005]

Hi Dave,
I am a little lost now to be honest. What was you going to query last night?

1.065 kOhm appears to simply be a hair over 1 thousand ohms.

The meter is a Fluke 88 Automotive meter. The meter is auto scale ranging.

I have tested a fuel injection control module following the vehicle manufacturer data sheet.

The confusion for me was in the display reading when the meter presented kOhm. The decimal point was also a misleading part for me. To me 1000 is one thousand but the meter saying 1.065 kOhm mislead me a bit. 1.065 is not a thousand and 65, it is in my understanding 1 unit or an ohm and 65 thousands of an ohm I think.

I read 1.065 kOhm to read one thousand and 65 ohm. I was confusing myself because of the way the meter displays the result 1.065, which should be multiplied by 1000 because of the k being present, which I think it should then it would read 1065 Ohm thus losing the decimal point.

I would like to say thank you to all who replied to this thread.

Thanks, I have been out of the electronics trade for over 24 years so am very rusty again in learning what I used to know.

Thanks Martin.

We always drive on the right side of the road, whether that be the left or the right

1.065 kΩ is just that 1 thousand and 65 Ohms
