Feature of ETCR3500

  • 5-inch touch colorful screen, the test data is displayed on the same screen. It is very convenient to do the test operation and view history data.
  • Insulation resistance range: 0.005MΩ~ 10TΩ.
  • Output rated voltage max reach 7 gears (50V, 250V, 500V, 1KV, 2.5KV, 5KV, 10KV).
  • Max short circuit current 5mA.
  • Large output power, strong anti-interference ability, and with stable test capability in large distributed capacitance site (such as long cables) and strong electromagnetic interference environments (such as substations).
  • Perfect measurement feature: Insulation resistance test (IR), polarization index test（PI), dielectric absorption ratio test (DAR), Step test(STEP), Voltage(V).
  • Custom setting measurement mode: PI, DAR calculation formula can be selected to provide users with multiple choices.
  • Custom setting voltage mode: the test voltage and test duration can be set freely, which is convenient for special site.
  • Voltage monitor: Automatically monitor the live voltage of the measured object. The voltage exceeds 36V will automatically prohibits the test to effectively protect the instrument and the operator.
  • Current monitor: Automatic display the current of test circuit
  • Temperature monitor: Automic display the temperature and humidity of tester inside.
  • Automatic discharge function, automatically and quickly release the electric charge of the tested object after the test, no need
  • Large capacity rechargeable lithium battery pack 14.8V 5200mAh, to ensure long-term testing work.
  • Large-capacity test record memory, test records can be browsed and analyzed directly in the tester, can automatically store the real-time test data with test date and test timing and total of 1000 groups.
  • USB communication and upload function, the record data can upload to computer store and analysis.
  • Bluetooth communication function, which can upload the tests result to mobile.
  • Double shell structure, which is durable and the  protection level reach IP65
