Megger S1-1068 10kV DC Insulation Resistance Tester

With class-leading noise rejection of 8 mA - twice that of most comparable instruments - and enhanced software filtering that has four user-selectable options, Megger’s S1-1068 10kV dc insulation resistance tester delivers dependable results in even the most severe of electrical environments, including high-voltage transmission and distribution substations. Five preset voltage ranges are provided in insulation test mode, plus a user settable lock voltage range. Preconfigured diagnostic tests include Polarisation Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Stepped Voltage (SV) and Ramp test. Other innovative features of the Megger S1-1068-UK include provision for remote control via a fully isolated USB port, which makes the instruments ideally suited for use in production environments, and internal storage for date-and time-stamped results. Stored results can be recalled to the display, downloaded via a Bluetooth wireless link or accessed via the USB port.
