Page 6 of 25 SPEC-DMM7510 Rev. B / October 2016
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)
and 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
