measuring ohms.

[Sniper82]

I want to know what tool is used to measure ohms? Like if a lasers pot is knocked off a little how do I know measure how many ohms to turn it back?

How do I used the tool?

An ohmmeter is usually part of a Volt-Ohm-Ammeter (VOM). There are jillions of 'em on the market: analog (with a needle), digital (direct numeric readout), cheap ( ~couple dollars) to professional models costing hundreds of dollars. radio Shack, Home Depot, or any electronics store (and some computer stores) will have VOMs.

You will not be able to set the right value without a schematic or repair guide. If the value was fixed, they wouldn't put a potentiometer in the circuit. Settings like that usually read "turn to increase the voltage to XX millivolts" or " adjust the value until the voltage at (some component) is xx volts.

If you don't know what that voltage values is (or the result of what that potentiometer controls), then having the meter is useless. You'd be locked into the "mess with it until it either works or is completely dead" situation, and you don't need a meter for that.

Sorry / Good Luck
