Imperviousness to erosion via air at lifted temperatures. In stainless steels, chromium is the most critical component for expanding the scaling resistance particulary at temperatures above 1000°
Because the meter is actually measuring the current through the resistor, and the two quantities ... current and resistance ... are inversely proportional. So when the meter measures more current, it has to read less resistance, whereas higher resistance will result in less current. So the numbers for resistance have to be printed "backwards" on the meter scale.
An ohmmeter typically uses a logarithmic scale to measure resistance. This scale allows for a wide range of resistance values to be displayed compactly, making it easier to read both low and high resistance levels. Some digital ohmmeters may also use linear scales for more straightforward readings in certain ranges. Overall, the choice of scale enhances the accuracy and usability of the device.
Mega = million Megaohm = 1000000 Ohms
In a standard ohm scale, the resistance that is typically found at the center of the scale (r x 1) is usually 1 ohm. This is often the reference point for measuring lower and higher resistances in various applications. The scale usually extends to both lower and higher values, with 1 ohm serving as a benchmark for comparison.
This is because the resistance is measured by applying a fixed voltage to the resistor and measuring the current. Since I = V/R, the current/resistance relation is non-linear.
Resistance is measured in ohms, so some refer to the resistance scale as the ohms scale.
The HR scale stands for Health Resistance
zero is low resistance
ln reverse biase high resistance and in forward biase very low resistance
The scale that compares the resistance of the surfaces of minerals to scratching is called the Mohs scale of mineral hardness. It ranks minerals on a scale from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.

The scale of an ohmmeter is not linear; it is typically logarithmic. This means that as resistance values increase, the corresponding scale intervals become progressively larger. This design allows for easier reading of both low and high resistance values, as low resistances can be more precisely measured while still providing a readable scale for higher values.
The Mohs scale of mineral hardness is the system used to identify the scratch resistance of various minerals based on the ability of a harder material to scratch a softer material. Minerals are ranked on a scale from 1 (softest) to 10 (hardest) on this scale.
