Measuring Resistance

How to read the resistance from the DMM.

If you wish to measure the registance accurately, make sure to hold the register tightly with the probe.

How to read the resistence by the color code on the surface of registers.

Colors' Values
Brown 1
Red 2
Orange 3
Yellow 4
Green 5
Blue 6
Purple 7
Gray 8
White 9
Black 0
Gold 5% error
Silver 10% error

For example:

A register that has color codes of brown, black, red, gold can be measured as follows:

1) (brown, black, red, gold)=102(5%)=10*102(5%)=1000 ohm
(5%) error indicates that the resistance is greater than 950ohm but less than 1050ohm.

Second Example which was shown in the photo above can be calculated through:

(orange, orange, brown, gold)=330(5%)=33*101(5%)=330 ohm
(5%) error indicates that the resistance is greater than 313.5ohm but less than 346.5ohm.

The value from the DMM, 333.7ohm, satisfies the range shown above on the 2nd example.
