4. Resistor used to calibrate Model 2601/2602 3A and 10A ranges and Model 2611/2612/2635/
2636 1.5A and 10A ranges should be characterized to uncertainty shown using resistance
function of a digital multimeter before use.
5. Used for contact check calibration. Characterize resistors using ohms function of digital
multimeter before use.
6. Standard is a guarded and characterized 1GΩ resistor used to test Model 2635/2636 100pA to
100nA current ranges.
