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 200M

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.
