Reading Ohm Meter????
I'm trying to adjust my TPS but i'm not sure what to set the ohm meter at to get the readings the direction say I should get, the directions don't say.......????? There are 6 different settings for ohms on mine and I'm trying to read a resistance of <2.3K and open/infinate??? Thanks for your time....TIM

What kind of meter is this? but for 2.3k and if its not like a thousand dollar meter its lowest settings should show you less then 2.3...Fortunately for me unfortunately for you, I have no experience with analog meters and I use mine daily....

A few tips:
1. Head to Radio Shack and buy a couple of resistors, like a 1000 ohm (1K) or thereabouts. Then clip the red lead to one side of the resistor, black lead to the other side and set the meter to ohms (some also need to move the probes from one plug to another). Then try to get some sort of reading that makes sense. Depending on the scale, you are likely to get a reading of "1.0" (+/- 5% or 10% depending on the resistor tolerance), this would be the reading on a 2K or 20K range. On a 2K range the readings will go from 0.001 (x 1000 or 1 ohm) to 1.999 (x 1000 = 1999 ohms). On a 20K range the readings would go from 0.001 (x 10000 = 10 ohms) to 19.99 (x 10000 = 19,990 ohms).
2. Don't want to spend the money on a resistor? Then hold the red probe in one hand and the black in the other hand and touch the two probes together. With meter on the ohms scale, you should get a 0.000 reading, this is zero ohms, i.e. a dead short. Then separate the probes and you should get some sort of indication of an open circuit (infinite resistance), some meters read "00" (looks like the sin for infinity) or "0L" or the display can be blank, this varies from meter to meter.
I'll have a digital photo in a few hours, once my camera battery recharges.
As promised a photo and usage guide has been added to the web page:
