</STRONG>

How come my car will go 100 miles an hour when the speedometer only goes to 80?

Or why can I get 16 gallons in my 15 gallon gas tank? strange..

Well dude i tell ya ITS NOT!

Guys belive me im equally suprised .. as you are ...... i have changed five meters to check this and they all show me the same ?

Im really confussed here how ???? i know its not possible but then its showing me???

Well i shall remove some photos and post it here so you guys can see it !

I have a better idea, just stick your meters where the sun don't shine, and go away, there is no way that it is possible, so, don't even attempt to try to convince us...

Hey skinny im not trying to convince anybody for anything .. im surprised .. myself !!

Just yesterday i checked it again and it shows me the same...??? im confused myself

i know technically its not possible .. but then ....??????/ HOW COME!!!!!!

PSU in my car shows me 1.68 amps and a new one is showing me 3.3amps

Can it be that the chips i got from National has a higher amp value or the T6 has a higher amp value ... ?????

how exactly are you checking this???

**Mastero** · 11-06-2001, 05:27 AM

i just connect it normally and the red led is on .

Then i checked the vdc with this yellow colour multimeter and the vdc are all perfect. cool then i check the amps now in the multimeter there is this connection for amps meaning the positive goes in a different slot for the amps and i move the dial to amps were its said 10amp max.

fine i check the 3.3rail 4.98amp 5vdc rail 5.1amps 12vdc rail 3.3amps ???????????

well ?

Its like the red wire of the meter goes to the 12vdc rail and the black wire to the ground

This is where a basic knowledge of electronics principals would have helped you. To measure voltages with a meter you connect the meter in PARALLEL with the device your want to measure the voltage ACROSS (ie. place the meter probes either side of the component under test).

To measure current THROUGH a component you place the meter in SERIES with the component (ie. break the circuit and remake it with the meter in series).

What you had done before (with all 5 meters) was effectively short circuit the 12V while measuring the current flowing through the meter. If you had looked at the voltage at the same time you would have seen it was a lot less than 12V.

Maybe this guide will make it simpler.

Well, could be me,

But I always thought, if you want to measure the current, you have to wire it in like serial. Not just make a paralles contact.

When you measure voltages you are right. Red cable goes to + and the black to ground.

But when you measure amps (current) you have to wire it in. How else should the multi-meter know how much electricity runs through the cables...

It's like this.

Output of PSU --> red clamp multimeter --> multimeter --> black clamp multimeter --> harddisk / mobo.

You are right that you need to change the sockets on the multimeter. but it has to be wired in serial.

Try to measure your current this way, and let us know what you get then.
Hope this helps you out.

PS. If I'm wrong about this method, please shoot my head off

EDIT: PS... damned.. ehehhe.. sproggy beats me while I was typing the message.. sorry for the flooding.
