Double Clamp Multi-function Grounding Resistance Tester , Soil
Resistivity Tester , DC Resistance Tester
I. Product Introduction :
The UT575A grounding resistance tester is microprocessor controlled
to accurately detect 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 can be 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.
The measurement usage of the tester inludes as following:
1. 2/3/4-pole measurement Ground Resistance, Ground Resistance range0.01Ω~30.00kΩ
2. Selection method, double clamp method to measure the grounding resistance
3. Soil Resistivity 0.01Ωm~9999kΩm
4. Ground Voltage 0.1V~100.0V
5. AC current leakage current measurement 0.01mA~1000A
II. Main Features
1. Large-diameter current clamp design for measuring any grounding
resistance of complex grounding conditions such as single point and
mesh grounding;
2. Precision 4-wire method, 3-wire method and simple 2-line method,
selection method, double-clamp method measurement;
3. Fast filtering technology, with excellent anti-interference
ability and environmental adaptability, repeated test consistency,
ensuring measurement accuracy, stability and reliability.
4. Data storage function for 500 sets of data storage;
5. Upload to PC via USB data cable for display analysis and output
test report
