Product Function
Suitable for insulation resistance testing of cable, motor, generator, transformer, mutual inductor, high voltage switch, arrester 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, and the test data will be displayed on the same screen. It is very convenient to test operation and view history record.
2. With the unique strong anti-interference technology and stable testing capabilities in large distributed capacitance site (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, which can provide variety of options to user and convient the special site request.
5. Voltage monitor: Automatically monitoring the live voltage of the measured object. when the voltage exceed 36V and will automatically prohibit to test to effectively protect the instrument and the operator.
6. Current monitor: Automatic display the current of test circuit.
7. Temperature monitor: Automic display the temperature and humidity of tester inside.
8. Automatic discharge function, automatically and quickly release the electric charge of the measured object after the test, no need the external discharge circuit.
9. Large-capacity test record memory, test records can be directly browsed and analyzed in the tester. the tester can automatically store 1000 sets of real-time test data with test date and test time.
10. USB communication and upload function, the recorded data can be uploaded to the computer for stored statistical analysis.
11. Bluetooth communication function, can upload the test results to the mobile phone.
