Features & Benefits

After years of development of high resistance bridge measurement systems and resistance standards, Measurements International (MI) is pleased to announce the launch of the 6652A High Resistance Meter, available in two configurations: Base and Premium.

The 6652A offers users flexible operation in a simple, easy to use “meter-like” package.

The model 6652A High Resistance Meter is designed to measure high resistance in the range of 1 MΩ to 100 TΩ. The simplified construction and operation offer a more user-friendly approach to high resistance measurements, and to improve measurement speed over other single-input devices.

Direct Measurement Mode: In this mode, the 6652A offers users the ability to quickly establish nominal values of resistances, measure insulation resistance and volume and surface resistivity. This mode is also useful for determining resistors time constant, as well as voltage and temperature coefficients.

Resistor Substitution Measurements: (Only available for 6652A Premium) In this mode, high-accuracy is obtained. The measurement of a standard of known resistor is automatically compared to a resistor under test. With this method, any hardware drift and instability are taken into account, consequently are corrected for the unknown resistance measurement.

Voltage Range: The voltage range of the 6652A Basic is variable from 1 V to 1000 V. The voltage setting is indicated on the front panel display.

Operation: The front panel offers users simple and intuitive measurement options. Features include resistor protection, voltage setting, settle time of the resistor, the number of measurements, number of statistics and graphing.
