checking Dexcool with voltmeter?

I read a post about checking your Dexcool that said to put the negative lead on the negative post of the battery and the positive lead into the Dexcool & that a reading of .2-.5 is good. .2-.5 what? What setting should the meter be set on, DC volts, Ohms, what? Consider me an electrical imbecile... :-) Thanks!

I would bet DC

definetly Volts DC and very small Voltage if it has multiple settings for that.... anything .4 volts or higher i would prolly no bueno to me thats just my opinion with that much eloectrolosis in the water seems like a bad idea...GL :thumb:
