Lower FAIL displayed in withstanding voltage test

QI am getting a "Lower FAIL" reading even though I tested the withstanding voltage of a known-good product.

A

Negative resistance value on a DMM

QMy DT4253 displays "-40 ohm" in resistance measurement. Why does this happen?

A

Effective measurement range of power quality analyzer

QThe voltage range of the PQ3198 is 600V only. Is it possible to measure a 690V circuit?

A

Hysteresis of power quality analyzer

QWhat is "hysteresis" in the event setting of the PQ3100?

A

Cannot connect GENNECT Cross with an instrument

QI cannot connect the GENNECT Cross mobile app with an instrument. What should I be checking?

A

Cannot install the LR5000 Utility (Windows 10)

QI cannot install the LR5000 Utility on my Windows10 PC. The .NET Framework 4.7 is already installed, but ".NET Framework 2.0 is necessary." appears.

A

Power Quality Measurement Guidebook

QDo you have any guidebook explaining the power quality measurement procedures and case studies?

A

Inductance measuremet of inductor coils

QIs there any guidebook about the inductance measurement of inductor coils?

A

Capacitance measurement of MLCC (Multi-Layer Ceramic Capacitor)

QIs there any guidebook about the capacitance measurement of MLCC?

A

Impedance measurement of SMD components

QHow should I measure the impedance of the PCB transmission path, antenna, and SMD components with high frequency?
