ITEMS DESCRIPTION
UT575A grounding resistance tester,
Controlled by a microprocessor,
Accurately detects ground resistance,
Soil resistivity,
Ground voltage,
DC resistance and AC current.
The same screen shows the resistance value of the auxiliary electrode, which is convenient for judging the measurement error caused by
environmental factors, and it is convenient to measure the true resistance value of the grounding resistance more accurately.
At the same time, 500 sets of data are stored, and the monitoring software can monitor the data online.
The USB data is uploaded to the PC and has unique functions such as numerical maintenance and intelligent alarm prompts.
Features
Large-diameter current clamp design for measuring any grounding resistance of complex grounding conditions such as single point and mesh grounding;
Precision 4-wire method, 3-wire method and simple 2-line method, selection method, double-clamp method measurement;
Fast filtering technology, with excellent anti-interference ability and environmental adaptability, repeated test consistency, ensuring measurement accuracy, stability and reliability.
Data storage function for 500 sets of data storage;
Upload to PC via USB data cable for display analysis and output test report
