Resistance Measuring Instruments FAQ
Q: What is the difference between 2-wire and 4-wire measurement methods in resistance measuring instruments?
A: The 2-wire method is simpler but includes lead resistance in the measurement, making it less accurate for low resistances. The 4-wire (Kelvin) method uses separate current and voltage leads, eliminating lead resistance effects and providing more precise measurements, especially important for resistances below 1Ω.
Q: How often should resistance measuring instruments be calibrated?
A: Calibration frequency depends on usage and environment. For most professional applications, annual calibration is recommended. In critical applications or harsh environments, quarterly calibration may be necessary. Our instruments include calibration reminders and come with traceable calibration certificates.
Q: Can resistance measuring instruments test insulation resistance as well?
A: Many of our advanced models combine both low-resistance and high-voltage insulation testing capabilities. For example, the RM-300 series can measure from 10μΩ to 10GΩ, covering both conductor resistance and insulation resistance tests in a single instrument.
