【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
Comes with Japanese customer technical support and a Japanese instruction manual for safe operation.
[Ultra Precise Earth Resistance Measurement] ETCR3000A+ earth resistance meter can measure the range from 0.10Ω to 2000Ω with a resolution of 0.01Ω, making it ideal for critical systems with low resistance. It also accurately measures AC voltages up to 200V with 1V resolution. This equipment is equipped with excellent anti-interference design, ensuring stable performance even under difficult environments.
[Automatic Wire Resistance Correction] Our new technology corrects errors caused by poor test lead contacts or extension cords, ensuring high accuracy in field measurements.
[Auxiliary ground rod determination] The earth tester is equipped with an auxiliary earth rod determination function, which improves the accuracy of ground resistance measurements on site.
[Lightweight and field applicable design] The earth resistance meter is only 470g, and the compact main unit is easy to carry. User-friendly and intuitive operation thanks to the top-mounted interface, vertical hand-held format, and easy rotation knob.
【Durable for Industrial Work】Made of ABS material, the ground resistance meter is durable and moisture-proof, and the device features a backlit LCD display that is easy to read under all light conditions, ensuring reliable performance even in difficult environments.
