Resistance Meters Q & A
Q: What's the difference between 2-wire and 4-wire measurement?
A: 4-wire methods eliminate lead resistance errors for more precise low-resistance measurements.
Q: How often should resistance meters be calibrated?
A: Annually for most applications, or quarterly for critical measurements.
Q: Can resistance meters test live circuits?
A: No, always de-energize circuits before resistance testing to prevent damage.
Q: What safety standards apply to resistance meters?
A: Look for CAT II or CAT III ratings for electrical safety.
Q: Are Chinese-made resistance meters reliable?
A: Many are excellent quality - focus on reputable brands like UNI-T or Victor.
