How do you read off the ohms on a multimeter?
There are generally three sets of scales on the face of a multimeter. One is a linear scale: voltage and current are measured using this scale. The maximum (rightmost) value of the scale is the range of voltage and current, which can be read in equal parts. (Only the AC voltage 10V block is separate in this group.) The inner most circle is the logarithmic scale - the decibel scale. The outermost circle is the resistance block, and the reading method is from right to left. The right side is 0 and the left side is infinity. The center resistance is the internal resistance of the block. The actual value is equal to the surface reading multiplied by the multiplier.
The unit of the number displayed in 200ohm is ohm;
The unit displayed in the on-off gear is also ohms;
The unit of the number displayed on the kilo-ohm setting is Kohm;
The unit displayed in megohm is megohm.
Resistance 200 ohms, the unit is ohms.
2K, 20K units are kilo-ohms
Therefore, the reading plus the unit is the real value
Because the maximum range of 200 ohms gear is 200, take 30 can be
But 2K maximum range is 2, will not show 30
The maximum range of 20K is 20, and it won't show 30.
If the readings are all 1
It's 1 ohm, 1 kilo-ohm, 1 kilo-ohm in that order.
Resistance 200 ohms, the unit is ohms, 2K, 20K units are kilo-ohms, so the reading plus the unit is the real value because 200 ohms maximum range is 200, take 30 can be but 2K maximum range is 2, will not show 30, 20K maximum range is 20, will not show 30, the readings are 1, then, in turn, 1 ohm, 1 kilo-ohm, 1 kilo-ohm.
The top row of the dial is the resistance scale, labeled from right to left with these

The week of the selector switch is divided into five zones:
The uppermost is the AC voltage gear, the second zone to the right is the resistance gear, the
The third area is the transistor test file, the fourth area is the DC current file, the fifth area is the DC voltage file.
In the resistance gear there are five gears namely:
X1; X10; X100; X1K; X10K.
The basic unit of resistance is the ohm. When reading the value, with the pointer stopped at the number, multiplied by the switch in the gear multiplier, that is, the actual resistance value.
For example: when testing resistance, the pointer stops at 30 on the dial resistance scale, the switch hits the X1 gear, the resistance is 30 ohms.
If the switch to play in: X10 gear, it is 300Ω, X100 gear is 3000Ω (3K).
X1K is 30KΩ, X10K is 300KΩ.
