Low Resistance Measurement Instrument

It is an electromechanical instrument used for measurement of low resistances.

Low resistance measurement instrument.

The resistance elements to be used for such measurements however need to of special construction. We produce a comprehensive range of low resistance ohmmeters and accessories which cover most measurement applications. We have also included useful tables of wire and cable characteristics temperature coefficients and various formulas to ensure you make the best possible choice when selecting your measuring instrument and measurement technique. What does the low resistance measurement tell the operator.

Resistance r is the property of a circuit or element that determines for a given current the rate at which electrical energy is converted to heat in accordance with the formula w i2r. Low resistance measurement techniques explains common causes of errors and how to avoid them. Voltmeter ammeter method for measuring low resistance. It comprises of a permanent magnet similar to that of a pmmc instrument and two coils in between the magnetic field created by the poles of the magnet.

This handbook gives an overview of low resistance measurement techniques explains common causes of errors and how to avoid them. Cropico is a world leader in low resistance measurement. This method due to its simplicity is very commonly used for measurement of low resistances when accuracy of the order of 1 is sufficient. The two coils are at right angles to each other and are free to rotate about the common axis.

The practical unit is the ohm. Cropico is a world leader in low resistance measurement.
