Super Megohm Meter Hioki Sm7420

4CH Microcurrent Measurement SUPER MEGOHM METER SM7420

Characteristics of the MLCC Leakage Current Test System This high-speed test system combines the 4ch microcurrent SUPER MEGOHM METER SM7420 with an external power source, or the 8ch SUPER MEGOHM METER SM7810, developed for leakage current tests, with a 32ch output POWER SUPPLY UNIT SM7860. Perfect for equipping on automated machines, use this to construct the fastest MLCC leakage current inspection line.

High-Performance Contact Checks

[Low capacity contact checks] The SM7420 is equipped with contact checks that can identify low-capacity capacitors of only a few pF as well as measured objects with a small capacitance. (Reference value: 0.1 pF to 99.99 pF) [CH independent contact checks] The SM7420 using an external power source enables check frequencies and delay settings to be changed for each measurement channel, achieving detailed settings that match the line design.

1/60 Variability, 300x Noise Resistance

Stability (repeatability) against power supply noise and external noise has improved dramatically due to a combination of new Super Megohm floating circuitry and triaxial connectors. Variability in normal usage environments is reduced to 1/60 compared to previous models, and to 1/300* in conditions where 50 V noise is applied.
