Measuring ranges of resistors with a multimeter, VOM, Tester

Note: Due to the variety and types of multimeters explains the method is considered a base that must be common to most of these.

This case is especially found in the analog meter, but can be applied to digital multimeter

The range selector of resistance is different from the voltage and current .

Whenever the function is in ohms, the measured result is multiplied by the factor shown in the range
Normal ranges are: RX 1, RX 10, RX 100, RX 1K, 10K RX, RX 1M. Where K stands for kilohms, and megohms M
A practical example (see options selector in yellow on the chart)

If the display of a multimeter to measure resistance, it reads 4.7 and the range shows: x 1000 or x 1K.

The VOM would be measuring a resistor of value 4.7 x 1000 = 4700 or 4.7 K (kilohms). Check the chart.

It is very important to choose the proper function and range before making a measurement.

If a wrong can damage the tester / VOM in final form.

In addition, an analog meter has two knobs for adjusting the needle to zero (resting position) and the other to adjust the reading to zero ohms (0).

To do this proceed as follows:
1 - Put the function in Ohms
2 - Put in the range: x 1
3 - connect the probes.

At the end of the needle above process must be 0 ohms (ohms). If no adjustment is made ​​with the knob (with the ends together, creating a resistance of 0 ohms).

Note:
- Multimeter VOM = = = Polymer Tester.
- Ohmmeter is called, in this case, the meter ready to measure resistance.
