In this new web series, Ask a Product Manager, HIOKI invites you to submit your product and technology questions to our Product Managers. We’ll address them here so our whole community can benefit. This week’s installment focuses on LCR meter performance with two questions from a prospective customer. “We currently have a network [...]
October 6, 2019 - Nagano, Japan Hioki is pleased to announce that its AC/DC Current Sensor CT6877, AC/DC Clamp Meter CM4375 and CM4376, and AC Clamp Meter CM4141 and CM4142 have been recognized with 2019 Good Design Awards by the Japan Institute of Design Promotion. 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 [...]
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 introduce measurement errors. By keeping the electrical [...]
Fault Ride-Through (FRT) To ensure critical equipment continues to be up and running despite power quality problems such as voltage dips, companies must make sure that adequate fault ride-through capability is included when the equipment is purchased. Customers then use the fault right-through or FRT capability curves that manufacturers provide so that they can properly [...]
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 [...]
Electricity theft is often an “invisible” crime. Someone illegally taps into a power supply, hooks up a line that has been disconnected, or tampers with a meter to avoid recording electricity usage. For example, some people will reverse their meters so they run backwards, others with crack the meter seal open and place mechanical brakes to [...]
Join us for a webinar on Aug 14, 2019 at 3:00 PM EDT. Register Now! Depending on the circuit characteristics and the amount of AC or DC current that is expected, engineers have a broad array of choices at their disposal for current measurement. This webinar addresses the most popular current measurement techniques, and [...]
The accuracy and tolerance described in the product specifications for many Hioki measuring instruments are given in terms of rdg., f.s., and dgt. Measurement uncertainty is often defined, and the uncertainty limit is obtained from the extent of these values, but we have found that many customers are not familiar with the terms. Let's take this opportunity [...]
6 Current Sensing Methods A few months back, we posted a blog discussing the 6 different current sensing methods used in the current meters and sensors developed by Hioki. Here, we’re highlighting the sensors that incorporate a Hall Element to detect current. A Hall Element is a semiconductor sensor that applies [...]
