Histek UT620C Plus Micro Ohm Meter 0.001mΩ～300.0KΩ Auto & Manual Range Megohmmeter Tester Tool Data Storage

Description

Product Overview

The Histek UT620C Plus is a professional‑grade micro‑ohmmeter designed for demanding electrical testing environments. It covers an exceptionally wide resistance range from 0.001 mΩ to 300 kΩ, allowing users to detect minute resistance changes in cable conductors, motor windings, relay contacts, and high‑voltage equipment. The instrument delivers a measurement accuracy of ±0.1 %FS and supports a test current up to 1 A, ensuring that even the smallest variations are captured with confidence. A large, high‑contrast LCD provides clear real‑time readouts, while an automatic shutdown feature conserves battery life during idle periods. The device is CE and RoHS certified, confirming compliance with European safety and environmental standards. Its rugged housing, reinforced keypad, and protective rubberized corners are engineered to withstand drops, spills, and the rigors of daily field use.

Usage

Engineers, technicians, and maintenance professionals rely on the UT620C Plus for a variety of on‑site applications. In cable testing, the meter quickly identifies high‑resistance joints and corrosion that could lead to power loss or overheating. When measuring motor windings, the device’s high‑resolution capability helps balance phases and detect insulation breakdown before catastrophic failure occurs. The built‑in 500‑record data storage enables users to log each measurement, label it, and retrieve the data later for trend analysis or compliance reporting. The instrument’s compact dimensions (7 × 3.5 × 2 inches) and lightweight design (4 lb) make it easy to carry in a tool bag or attach to a belt loop, ensuring that accurate resistance testing is always within reach, whether in a factory, on a construction site, or in a remote field station.

FAQ

What is the minimum resistance the UT620C Plus can accurately measure?

The meter can measure down to 0.001 mΩ, making it suitable for detecting very low‑resistance faults in cables and motor windings.

How many measurement records can be stored, and how are they accessed?

The device stores up to 500 readings. When the memory is full, the screen displays “FULL,” prompting the user to delete or export data. Stored values can be reviewed directly on the LCD or transferred via the optional USB interface.

Is the UT620C Plus suitable for high‑voltage environments?

Yes. While the meter itself measures low resistance, it is designed for use alongside high‑voltage equipment, providing safe isolation and accurate low‑resistance diagnostics without compromising operator safety.

What power source does the meter use, and how long does the battery last?

The UT620C Plus operates on a rechargeable lithium‑ion battery. With typical usage, the auto‑shutdown feature extends standby time to several weeks, and a full charge supports up to 20 hours of continuous operation.

Can the meter be calibrated in the field?

Yes. Histek provides a portable calibration kit and detailed procedures, allowing technicians to perform on‑site verification and maintain measurement accuracy without sending the unit back to the factory.
