This product focuses on portability and ease of use, with an aviation aluminum alloy shell weighing only 3.5kg, which can be carried by one person for operation. It has a 16GB storage capacity that can store more than 1000 sets of test data, supporting USB export. It adopts a 0.5-class high-precision sensor, with the test error controlled within 0.5%. It supports AC/DC dual-mode output, adapting to different types of protection devices. It is equipped with an IP54 protection grade, which can cope with outdoor dust and light rain. It also has a one-key test mode, which does not require professional training to get started quickly, solving the pain point of insufficient technical capabilities of grass-roots operation and maintenance personnel. The backlit display screen supports operation in low-light environments, further improving the convenience of on-site operation.
Test Channels: 1-phase voltage + 1-phase current auxiliary channel; Output Voltage: 0~250V AC/DC, resolution 0.1V; Output Current: 0~20A AC/DC, resolution 0.01A; Accuracy Class: 0.5 class; Dimensions: 320×240×150mm; Weight: 3.5kg; Power Supply: Built-in 18650 lithium battery pack (8 hours battery life) + external AC 100-240V adapter; Communication Interfaces: USB2.0, RS232; Storage Capacity: 16GB, supporting CSV and PDF format export; Display Screen: 3.5-inch color backlit LCD; Operating Temperature: -10℃~+50℃; Storage Temperature: -20℃~+60℃; Protection Grade: IP54.
It is suitable for scenarios such as township small substations, enterprise distribution rooms and outdoor line maintenance, mainly used for calibrating single-phase overcurrent relays, overvoltage relays, leakage protectors, differential protection devices and other equipment. It can be used for daily inspection, fault troubleshooting and pre-commissioning detection of new devices for power operation and maintenance personnel. It adapts to outdoor operation scenarios without fixed power supplies, and the built-in lithium battery does not require long-term external power supply. It supports offline storage of test data, which can be uploaded to the background to generate standardized test reports, improving the efficiency of operation and maintenance work.
