Instruments Ideal for Component and Equipment Testing in Production Lines and MRONagano, JapanHIOKI E.E. CORPORATION is pleased to announce the launch of the RESISTANCE METER RM3544/RM3544-01 and RM3548.Numerous electronic components known as coils and inductors are used in power conditioners in solar power systems and motors and inverters in electric vehicles, all of which are seeing [...]
Verifying the Electrical Potential of large equipment: Increase the safety of equipment and systems by reducing the electrical resistance between ground connections (grounds and grounding wires) and metal equipment chassis. Hioki's Resistance Meter RM3548 can play a key role in this important function. When the ground potential of equipment increases, that equipment becomes more likely to malfunction or [...]
With the increase in battery capacity in recent years, currents flowing across busbars connecting batteries now exceeds 100 amps. In particular, high resistance values at busbar welds cause degradation of batteries due to the generation of Joule heat (RI2), potentially leading to serious accidents. As a result, management of weld resistance is becoming an even more [...]
What measurement principles do resistance meters use? When a current I is applied to the object under measurement, a resistance R and the voltage V are generated with the relationship R = V / I. The resistance R can be calculated using this relationship. Resistance meters provide three measurement methods: constant current (CC), which applies a [...]
