The MEG10-01 is a compact, microprocessor-controlled high-voltage DC insulation tester, which may be powered by internal rechargeable batteries or by connection to an AC supply. Measurement results are displayed on the custom analog and digital LCD display as either an Insulation Resistance or a Leakage Current. The MEG10-01 has realtime data output and on-board storage for subsequent download. There is an integral time for Insulation Resistance and Polarization Index tests. The test measurement range, subject to the test measurement voltage, is up to 500 Gohm on the digital display and to 1 Tohm at all voltages on the analog scale. Test voltages of 500V, 1000V, 2500V and 10,000V are available and are selected by two buttons on the front panel.
