CLAMP METERHioki Launches Clamp On Earth Tester for Multiple Grounding Use Convenient, Low-profile Sensor is Ideal for Confined Locations FT6380 / FT6381
HIOKI E.E. CORPORATION is pleased to announce the launch of the FT6380 Clamp On Earth Tester for multiple grounding use and the FT6381 featuring Bluetooth® wireless technology. The two products were developed specifically to meet the needs of customers in North America, Europe, and Asia, where there is high demand for multiple grounding measurements.
Thanks to the small size of the clamp sensor, the FT6380 and FT6381 deliver a new level of convenience especially when used in confined locations. At the same time, we have increased the size of the grip used to open the sensor, allowing the new meters to be operated with only half the force required for similar products offered by other companies. Finally, the FT6381’s incorporation of Bluetooth® wireless technology allows it to be linked to Android™ handsets for report creation.
Need for Grounding Resistance Measurement
“Grounding” generally refers to the act of connecting an electrical device with the ground (earth) in order to zero out any potential difference. Electrical equipment must be grounded for safety reasons because ungrounded devices (that is, devices with a non-zero potential difference) may cause electric shock if they malfunction or suffer degraded components.
Utilities and service contractors need to measure grounding resistance in order to verify whether a given device has been reliably grounded. While grounding ideally eliminates any potential difference, a potential difference does in fact occur between the grounded device and the earth. This fact signals the existence of a not negligible level of resistance, which is known as grounding resistance. It is absolutely critical that we measure grounding resistance in order to ascertain whether it has been minimized to ensure optimal safety.
Compact clamp-on sensor for ultimate convenience in confined locations
To date, grounding resistance testers from other manufacturers have been characterized by their heavy weight and large jaws, which complicate use of the instruments due to the difficulty of attaching them to ground wires. Responding to resulting demand for more compact sensors, HIOKI engineered a low-profile sensor just 20 mm wide for both instruments so that they can be used to measure ground wires that have been installed in cramped spaces. The sensor is 50% smaller by volume than sensors on existing competing products.
Larger sensor grip for improved workability
HIOKI has enlarged the clamp sensor’s grip so that it can be opened with just two fingers, enabling it to be operated with only half the force of existing competing products.
Low power consumption for extended use
The FT6380 and FT6381 use approximately half the power of competing products, maximizing work efficiency because they can be continuously used for longer periods of time.
Bluetooth® wireless technology for connectivity with Android™ handsets (FT6381)
The FT6381 features Bluetooth® wireless technology, allowing users to display data in real time on Android™ handsets and instantaneously create reports in the field including measured values, times and dates, and position data. This technology can be used to e-mail measurement results to an administrator in a remote office in real time.
Onboard storage for 2,000 data points
The FT6380 and FT6381 can store 2,000 data points (each including a grounding resistance value and a current value) in the field.
