Introducing AC Clamp Meter CM3281 and CM3291 - a Pair of AC Ammeters Engineered to Accommodate Large-Diameter Cables with All the Ease of Use You’ve Come to Expect from Hioki November 28, 2019 -- Hioki is pleased to announce the December 2019 launch of the AC Clamp Meter CM3281 and CM3291, a pair of large-diameter AC ammeters [...]
The Importance of Power Converter Efficiency Power converters such as transformers are widely recognized as one of the necessary components of an electrical distribution system. Similarly, inductors such as coil, choke and reactors used as filters in power supplies play a large role in storing and transferring energy in the power converters. Due to the importance [...]
Have you ever applied a clamp ammeter around a wire only to realize that you can’t see the display? Let's look further into viewing measured values remotely. If you try to forcibly change the orientation of the clamp ammeter because you can’t see it, you risk damaging the instrument, and if you poke your head in [...]
Hioki announces the launch the new SP7001/7002 Non-Contact CAN Sensor, scheduled for release in December 2019. Building upon the concept of the SP3000 Non-Contact Voltage Sensor, the new SP7001/7002 are specifically engineered to safely detect CAN-bus signals. 1. Detect in-vehicle CAN FD (CAN flexible data-rate) and CAN frame signals from above the wiring insulation The new Non-Contact CAN [...]
In an earlier blog post, we introduced the 6 different current sensing methods used in the current meters and sensors developed by Hioki. Here, we highlight the Rogowski coil method that enables the design of flexible sensors through the use of an air core (or coreless) structure. In a Rogowski sensor, there is no heat generation, [...]

CURRENT SENSOR This pass-through current sensor measures large currents [...]
Calibration is like a health checkup for your instrument Because it verifies the condition of an instrument, calibration is like a health check. Specifically, Hioki calibration services involve confirming the condition of an instrument at a particular point in time by comparing the ideal value indicated by a standard and the value indicated by the instrument [...]
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 [...]
