Resistance Characteristics
Maximum 4-Wire Ohms Lead Resistance
5 Ω per lead for 1 Ω range, 10% of range per lead for 10 Ω to 1 kΩ ranges; 1 kΩ per lead for all
other ranges.
Offset Compensation Selectable on 4-wire, 1 Ω to 100 kΩ ranges.
Open Lead Detector Default is off.
Autozero Off Error For 2-wire ohms, ±1 °C and ≤10 minutes, add ±(8 ppm of reading) + 1.5 mΩ for 10 Ω range, 15 mΩ for
100 Ω and 1 kΩ ranges, 150 mΩ for 10 kΩ range, 1.5 Ω for 100 kΩ range, and 15 Ω for all other ranges.
For 4-wire ohms, ±1 °C and ≤10 minutes, add ±(8 ppm of reading).
Input Current Limit For signals with a magnitude of +12 V to +40 V or –12 V to –40 V: ±13 mA source or sink, typical.
For signals with a magnitude of greater than +40 V or –40 V: ±130 µA source or sink, typical.
