UNI-T UT705 Single Function Loop Calibrator

Description

UNI-T UT705 Single Function Loop Calibrator The UNI-T UT705 is a handheld, single-function loop calibrator designed for high-precision work in industrial instrumentation and control systems. Its primary role is to verify, calibrate, and troubleshoot 4-20 mA current loops, which are the standard signal type for transmitting sensor data in process automation. It serves as a reliable reference tool for technicians to ensure the accuracy of transmitters, controllers, and other loop-powered devices. This device operates in two key modes: measurement and source/simulation. In measurement mode, it can accurately read DC voltage and, most importantly, the current in a live 4-20mA loop. A standout feature is its ability to simultaneously power a 2-wire transmitter and measure its output current, eliminating the need for an external power supply. In source mode, it generates a precise and stable DC current signal to simulate a transmitter’s output for testing receivers and control systems. Built for efficiency in the field, the UT705 features an ergonomic design with a clear LCD display and a logical button layout for one-handed operation. It includes advanced automated functions like stepping and ramping, which automatically cycle the output signal to quickly test the linearity and response of a connected device. This combination of precision, functionality, and automated testing features makes it a dedicated tool for improving calibration workflow. Features: Measures DC voltage, DC current, and 4-20mA loop current. Outputs/simulates DC current for testing. Provides 24V loop power to a transmitter while simultaneously measuring its mA output current. High accuracy of up to 0.02% for both measurement and output. Automatic ramp and step output functions for fast linearity detection. Ability to store and recall frequently-used settings. Compact, handheld, and ergonomic design for easy portability. Adjustable backlight brightness for various lighting conditions.
