First Build and Defective Multimeter

[Krewlife]

so i got my 28g kanthal in the mail today and decided to play around with it. I wrapped 2x 11wraps around a toothpick and i put it on my multimeter that i bought from fasttech and the numbers are jumping around all over the place anywhere from 1.4 to 3.6ohms. when i put it on my mvp to check the ohms it says its at 1.0ohm.

anyone experienced with a similar build know what this should be comming up as?

p.s i'll be buying a new multimeter soon (not from fasttech)

You know to 'zero out' the multimeter, by touching the leads together. For example, you get a number of 0.5. Black on neg, red on top of pos pin. Ω to lowest number. When you are measuring Ω, be very, very, very, very still. I control my breathing like I'm @ the firing range. If I do not, my Ω numbers jump all over, too. So if you get a number, of say, 2Ω, subtract the first number, the Ω equal 1.5. Hope this helps

Next time you describe a coil for the purpose of diagnostics... I would suggest that we need to know the diameter of the mandrel (coil ID) - and although it really doesn't have a bearing on resistance - if the coil is compressed or not.
The definition of a "micro" coil is one that measures 1.5mm (.063") or smaller ID... and although not a certainty, compressed.

A "typical" toothpick (or at least the ones on my desk) is 2.2mm (.087") in diameter... what your toothpicks measure, is a mystery. Regardless, an odd size... but with a bit of extrapolation, your coils should measure 1.5Ω+/- each - or if 2 coils in parallel, 0.7Ω+/- net resistance.
These numbers are, if anything, a bit on the low side - so adding a few tenths wouldn't be extravagant - and, not unsurprisingly enough, your MVP may prove to be a more accurate ohm meter than your useless POS paperweight FT DMM.

Praise be to the Vaping Gods. A good quality DMM is a joy forever... while I can generally guess more accurately than a lowball DMM reading.

Be careful when using multimeters as opposed to a vaping specific ohms reader.

Multimeters can often store resistance, so you need to find out what that is and then subtract that from the final reading you get. That is, unless your meter has a zeroing function.
In the proper mode, touch the red and black ends of the meter together and read what ohms the meter says. That is the amount you will need to subtract to get an accurate resistance of your build.
