Product Function
Suitable for insulation resistance testing of cables, motors, generators, transformers, mutual inductors, high voltage switches, arresters and other large equipment.
Insulation resistance test (IR); polarization index test (PI); dielectric absorption ratio test (DAR); Step test (STEP); Ramp test (RAMP); AC/DC voltage test (V).
Product Features
1.Touch colorful screen, test data is displayed on the same screen. It is very convenient for test operation and viewing history records.
2.With unique strong anti-interference technology, it has stable testing capability in large distributed capacitance sites (such as long cables) and strong electromagnetic interference environments (such as substations).
3.Perfect measurement index: insulation resistance (IR), polarization index (PI), dielectric absorption ratio (DAR), step (STEP), ramp (RAMP), AC/DC voltage (V).
4.Custom setting measurement mode: optional PI and DAR calculation formulas, custom setting test voltage and custom setting test duration, providing users with multiple options to meet special site requirements.
5.Voltage monitor: automatically monitors the live voltage of the measured object. Voltage exceeding 36V will automatically prohibit the test to effectively protect the instrument and the operator.
6.Current monitor: automatically displays the current of test circuit.
7.Temperature monitor: automatically displays the temperature and humidity inside the tester.
8.Automatic discharge function: automatically and quickly releases the charge of the measured object after the test, no need for external discharge circuit.
9.Large-capacity test record memory: test records can be directly browsed and analyzed in the tester. It can automatically store 1000 sets of real-time test data with test date and test time.
10.USB communication and upload function: recorded data can be uploaded to a computer for storage and statistical analysis.
11.Bluetooth communication function: test results can be uploaded to a mobile phone.
