Notes
Conditions: Auto V-source ohms, properly zeroed, 6½-Digit, 1 PLC, median filter on, digital filter = 10 readings.
1.  In the manual mode resistance can be calculated from specific source voltage and measured current. The measurement accuracy in the manual mode is
determined by voltage source accuracy and ammeter accuracy as follows: Measurement Error = R reading x (Voltage % error + Voltage offset error/
Voltage + Current measurement % error + 10 x Current measurement offset error / Current measurement range)
2.  Current measurement range for both Auto and Manual modes: 10% of current range ≤ measured current ≤ 100% of current range
