Measuring across the commutator opposites is a rough check - if each pair has the same resistance it is probably good but even then there are no guarantees. I have never seen the armature resistance stated for any motor though that doesn't mean such figures don't exist.

It would seem logical that each pair should be isolated but that generally is not how the armature is wired and each commutator segment is the termination of two coils.

In reality there is only three ways to test an armature - either build it into a motor and see if it performs ok, use an automated motor fault analysis machine or one of the dedicated armature testers such as an armature growler.

I don't know, maybe it is faulty or maybe it is telling you what you are trying to measure can't be measured on that range. I suggest you learn more by measuring a few known values to see what happens...

I have a Radio Shack multimeter and it was a complete waste of space from day 1 and no better after it had been "repaired" by the Tandy boffins. The readings vary wildly between summer and winter, often only half the display works and sometimes it doesn't work at all until it has been switched on for a while.

The short answer is no -- the difference between AM and FM is too great though some CB radios were made dual mode, like the President Veep I used to own.
Some CBs that found the way into Britain were powerful sidebanders that offered similar capabilities to unlicensed CB-ers to that official radio hams had to sit exams to enjoy. Some radio hams found it cheaper to have those top-line CBs modified for use on the 11 metre amateur band.

It would be no help to you to obtain a standard FM CB as when the UK was forced to legalise CB radio under the Treaty of Rome, they legalised it at a different frequency as the American frequency was already allocated to radio control, bleepers and other things. Special CB sets were manufactured for the UK market.

Hello there! Assuming your talking about "XtremeMan SOMA BT" I'm not a fan of assumptions but... if this is the device your are referring to then here you go below. If this is not the device you are making reference to, then please respond with the model number and make/brand of the device. Thanks for your visit and good luck.
1. With the unit on or off, plug the included cable
from the USB jack on your computer to the micro
USB jack v on this unit. While charging, the
battery level will be shown by the LED indicators
with the current level LED blinking. When all
the LED indicators light solid, then the unit
is fully charged.
2. If the power level is less than 10%, the left-most
LED indicator will start blinking, which means
that the Soma BT needs to be charged.
Using the Soma BT with a Bluetooth Device
1. Turn on the unit as shown above.
2. Press and hold the Bluetooth button U for
approximately three seconds until a beep
sounds and the right-most LED starts blinking.
3. Within five minutes, select Soma BT from the
Bluetooth List on the external device. See
external device's owner's manual for details.
When paired successfully, the Soma BT will beep
twice and the right-most LED will light Check Here
