Good morning neighbor, I got your call but we got home late and packing for Florida today:
I'm more familiar with olddddddd analog meters like my trusty reliable Simpson 260, but heres some info which may help:
1) There ought to be an R or Ohms or Resistance setting of some sort on the face of the meter. If a digital meter the range setting may???? be automatic (just an R and it sets its own range automatically) ...... If its an Analog it may have like Rx1 and Rx10 and Rx100 so if youre on Rx1 and the face reads 10 ohms its 10 ohms but if on Rx100 if it reads 10 that means its 1000 ohms.
2) Theres NO POLARITY when reading ohms, its just the resistance through an item regardless which lead (red or black) is connected to the ends of the item.
3) DO NOT try to read ohms when voltage is hot on an item and YOU SHOULD disconenct all other wires into and out of an item when measuring cuz the meter may read some other current path.
4) Remember OHMS is resistance THROUGH an item, end to end, copper wire and battery cables etc (extreme good conductors) should show near ZERO ohms unless theres a burned or loose or carboned or burned termination. Many cheaper meters arent very accurate at extreme low ohms values like 0 to 5 ohms. If you have a good battery cable Id expect it to read 0 0hms. NOTE an ohm meter passes low current and an item may read 0 ohms on a meter HOWEVER it may still be bad cuz when you pass several hundred amps through it (like when cranking an engine) its only then a major voltage drop happens across a carboned or loose connection. JUST CUZ A CABLE READS 0 OHMS DONT MEAN ITS NECESSARILY A GOOD CABLE!!!!!!!!
Sooooo looks for an R or Ohms or Rx1 or Rx10 etc scale on the meter face,,,,,,,,isolate a device so not a bunnch of other wires and possible circuit paths to it,,,,,,,,,,connect the leads to each end,,,,,,,MEASURE THE OHMS OF RESISTANCE,,,,,,,and short sections of copper wire or big cables should read near 0.
Call again if neeeded but were getting ready to head south and I will be on my cell phone in days to come FLORIDA FLYWHEELERS is soon ya know.
PS take it to the HS where you help out and let those young "dudes" help you.....If its digital they can if analog maybe not???

Today's Featured Article - Old Time Threshing - by Anthony West. A lovely harvest evening late September 1947, I was a school boy, like all school boys I loved harvest time. The golden corn ripens well and early, the stoking, stacking,.... the drawing in with the tractors and trailers and a few buck rakes thrown in, and possibly a heavy horse. It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
