East Hills Instruments

The 5068 is a precision instrument suitable for calibrating and testing general purpose insulation testers with test voltages up to 2.5kV. It is constructed in a high strength co-polymer plastic case and is powered by a rechargeable battery. This ensures full isolation from the mains and prevents stray leakage. The insulation tester being calibrated can be tested for open circuit voltage and short circuit current. These are displayed on the digital meter mounted on the front panel. Seven selectable precision resistors provide the insulation resistance test. A separate continuity test is provided. Also fitted are 4 fixed low resistance values for verification of the low ohm ranges. Also available is the 5069, 10kV version, see separate data sheet.
