2 INDIA2n FeaturesGenerate Test Voltages Across a Wide Spectrum The 3455 can generate test voltages ranging from 250 V to 5 kV. Settings can be made in steps as fi ne as 25 V. Very high INSULATION resistance measurement up to 5 teraohms is for All INSULATION Diagnostic ApplicationsFunctions such as automatic calculation and display of PI (Polarization Index) and DAR (Dielectric Absorption Ratio), as well as step VOLTAGE test, temperature compensation, temperature measurement, and leakage current display make the 3455 suitable for a variety of diagnostic Memory FunctionThe 3455 provides a manual storage function for 100 data and a logging function for 10 data (360 times). The date and time of measurement are also InterfaceEasily transfer data to a PC via the USB interface using our free PC application software.

3 The software also features a convenient report creation ForemostThe 3455 complies with FeaturesFeaturesGenerate Test Voltages Across a Wide Spectrum Generate Test Voltages Across a Wide Spectrum safety regulations for category IV measurements (600 V). A shutter mechanism prevents simultaneous use of measurement terminals and other terminals. Other safety features include a VOLTAGE measurement function, high - VOLTAGE warning indicator, and auto discharge , Easy to Read DisplayThe display is backlit and features a logarithmic bar graph as an analog type indicator in addition to the digital Range Test VOLTAGE SettingsActual output VOLTAGE > fl ashes if measurement range was exceededz INSULATION resistance measurementMeasurement VOLTAGE is selectable from 250 V, 500 V, kV, kV, and kV.

4 More fi nely graded settings are also possible. When measurement is completed, the unit shows the INSULATION resistance value, test VOLTAGE (setting and actual output), leakage current , DAR, PI, and elapsed Leakage current displayWhen measuring INSULATION resistance, the instrument can be switched to display leakage current . This is possible before, during, and after time INSULATION resistance valueInsulation resistance measurement displayz Step VOLTAGE testIn this type of test, the VOLTAGE is gradually raised and the INSULATION resistance and leakage current change is measured. Two different step settings are available: 500 V 1 kV kV 2 kV kV and 1 kV 2 kV 3 kV 4 kV 5 kV.
