Resistance Uncertainty: = ±[(ppm of reading) x (measured value) + (ppm of range) x (range used)] / 1,000,000.
% Accuracy: = (ppm accuracy) / 10,000.
1ppm of Range: = 20 counts for ranges up to 200MΩ and 10 counts on 1GΩ range at 7H digits.

Settling Characteristics: Pre-programmed settling delay times are for <500pF external circuit capacitance. Reading settling times are affected
by source impedance and cable dielectric absorption characteristics.
Ohms Voltage Drop Measurement: Available as a multiple display.
Autoranging: Autoranges up at 105% of range, down at 10% of range.

Ohms measurements at rates lower than 1 power line cycle are subject to potential noise pickup. Care must be taken to provide adequate shielding.
Specifications are subject to change without notice.
