Ok I hoped i posted in the right area but anyhow this meter I bought is pegged all the way to 60 ohms when not in use shouldn't it be at 0? I played with the adjustment dial it didn't really move anything, is it broken?

Adjustment dial may be very sensitive , or slow to change. Turn dial counter clockwise until it stops & touch leads together see what that does. Take a look at which ports leads are plugged into. Need to be common & volt/ohm. Third port on mine is for milli-amps.

I played with the adjustment dial it didn't really move anything, is it broken? The meter should show maximum ohms or infinity when not in use if set to measure resistance. When you hold leads together needle should got to zero. Using the meter shown in photo:  Using the blue scale at top of meter with leads apart meter shows infinity or greater than 2K ohms. If leads are touching needle will deflect to opposite side or to show reading of zero. With leads touching zero adjustment should be made. With selector set at x1 you should get a reading somewhere between 5 and 20 if measuring a factory wound arm. Hope this helps. |

I brought the adjustment to 0 with the leads touching now its reading 2 ohms on the arm?  |

Thanks for posting , Cordell.
Just to take one point a little further........ stock inline arms usually ohm around 6. Stock pancake from 14 ohms and up (think most of these today are in the 15 ohm range). Older , Aurora arms start at 16.
The closer the readings between poles the better. An arm that reads the same between all poles is balanced electrically. Each pole will generate the same magnetic force. Mechanically balanced is another story.

I've checked several they are stock run of the mill autoworld arms and they all read way too low I think this meter may be faulty I really value all this help thank you very much I was really looking forward to this metering of my arms this is frustrating

Are you getting readings that multiplied by 10 would bring you to this range ? |

Omg was I supposed to multiply the number? If thats correct then i'm looking at 18 ohms

It does say x10 on the dial duh I'm feeling really damn dumb right now I thought it would just read the ohms directly

Just read another it said 1.7 so x10 would be 17ohms yes?

It does say x10 on the dial duh I'm feeling really d**n dumb right now I thought it would just read the ohms directly Don't feel like that....... I just compared two meters. The digital one I use regularly and one with the needle. Digital read 14.6, 14.6, 14.7. Other meter set to x10 was reading a high 3 real close to 4. Switching to x100 gave reading of 1.4 just touching line for 1.5. Not sure what to say , try the x100 setting and see what that gives you. I've been using the same meter for near 30 years (yellow Sperry). Never bothered to learn other meter, basically got it for cheap spare. |

Just checked an tyco hp7 and got 4ohms sound right? Yes, no, maybe ? ............. most tyco arms ohm around 6 & up. Have two Tyco arms that ohm at 7 (w/green wire). 3.5 ohm arms were used for a while (think Matel was running company at time). Not sure of chassis designation at time. Believe HP-7's had a can mtr & single bar traction magnet ( never measured arm from one as I do not have any). Not sure, but think HP-x2 may have been designation of chassis when the 3.5 ohm arms were used. This chassis.is very much like their 440 x2.wide pan. Arm is held by plasctic bulkheads & 2 traction magnets were used. Think the lower ohm arms were intended to be used on battery powered tracks (low voltage). |
