Features
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 function. Large, Easy to Read Display The display is backlit and features a logarithmic bar graph as an analog type indicator in addition to the digital readout. Wide Range Test Voltage Settings Actual output voltage > fl ashes if measurement range was exceeded ❚ Insulation resistance measurement Measurement voltage is selectable from 250 V, 500 V, 1.00 kV , 2.50 kV , and 5.00 kV . 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 time. ❚ Leakage current display When measuring insulation resistance, the instrument can be switched to display leakage current. This is possible before, during, and after measurement. Elapsed time Insulation resistance value Insulation resistance measurement display ❚ Step voltage test In 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 → 1.5 kV → 2 kV → 2.5 kV and 1 kV → 2 kV → 3 kV → 4 kV →5 kV . The test time for each step can also be selected. ■ Primary Measurement Functions STEP 5.0 kV step voltage test Display of leakage current during measurement Actual output voltage Insulation resistance value > fl ashes if less than 1 nA Elapsed time leakage current value
