    Product Introduction
    ETCR3520 High Voltage Insulation Resistance Tester, also known as high voltage megohm meter and high voltage insulation resistance meter, The tester has complete various insulation resistance index test functions, self-set test voltage function, and good anti-interference ability. It has obvious advantage in substation and other environments with strong induction and large distributed capacitance. The instrument equip with true-color touch screen, and all test data and battery power are displayed on the same screen which is clear and obvious, the combination of the rotary switch and the button makes the operation very simple. The user does not need to memorize the operation method, and the operation method will pop up by clicking the "HELP" button on the screen, effectively guiding the user to operate the instrument. The tester is suitable for insulation resistance testing of large-scale equipment such as electrical equipment and transmission lines in large-capacity, high-voltage, and strong-inductive environments. It is a commonly used and indispensable instrument in the departments of electric power, telecommunications, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and power supply departments of industrial and mining enterprises. The test timer of the instrument automatically records the test time and stores the test results with date and time.The touch screen can easily check the recorded historical data. The completely isolated USB interface and Bluetooth communication can safely upload the test data to the PC or mobile phone for users to analyze data. The instrument provide with the test lines of double-layer insulation and shielding layer, and the high-voltage rod is equipped with replaceable alligator clips and hooks, which can be adapted to various test sites, The instrument adopt with solid double-layer shell structure. and the protection level of the case is lP65, which can prevent the intrusion of moisture and dust during transportation and storage, and prevent impact and effectively protect the instrument.
    1.5 inch true-color touch screen, test data is displayed on the same screen, can easily check the test operation and the recorded historical data.
    2.50V, 250V, 500V, 1kV, 2.5kV, 5kV 6 gears rated output voltage in total, wide measurement range 0.005MΩ~10TΩ. Max short circuit current: 7mA
    3.Large output power, strong anti-interference ability. It has stable testing capabilities in scenario with large distributed capacitance (such as long cable) and in environment with strong electromagnetic interference (such as substation).
    4.Complete measurement indicator: Insulation Resistance(IR), Polarization Index(PI), Dielectric Absorption Ratio(DAR), Step Test(STEP), Ramp Test(RAMP), Dielectric discharge index, Distributed capacitance (CAP) and AC/DC Voltage(V).
    5.Self-set test function: can choose PI, DAR and DD calculation formulas to provide user with a variety of options.
    6.Self-set voltage function(VS): test voltage and test time can be freely set to facilitate the need of special scenario.
    7.Voltage monitor: automatically monitor the voltage of the tested object. When the voltage is larger than 36V, the test is prohibited to protect the safety of the instrument and the operator.
    8.Current monitor: automatically display the testing loop current.
    9.Temperature monitor: automatically display the temperature and humidity in the instrument box.
    10.Automatic discharge function, automatically and quickly releases the charging charge of the tested object, no need external discharge circuit.
    11.Large capacity rechargeable lithium battery pack 14.8v 6400mAh guarantee long-term testing work.
    12.Large capacity test record memory, the test record can be browsed and analyzed directly in the tester and automatically records 1000 groups real-time test data with test date and test time.
    13.USB communication upload function, recorded data can be uploaded to PC for statistical analysis of stored data.
    14.Bluetooth communication function, can upload the test data to mobile phone.
    15.protection level IP65(when the cover is closed).
