DMM 7510 7½-Digit Graphical Sampling Multimeter

Resistance Characteristics

Maximum 4-Wire Ohms Lead Resistance

5

Ω per lead for 1Ω 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 ±(8ppm of reading) + 1.5 mΩ for 10 Ω, 15 mΩ for 100 Ω and

1 k

Ω 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.

Applies to ± ppm of range.

Peak noise uncertainty is included in DC specifications for

≥1 PLC.

Add peak noise uncertainty to measurements when < 1 PLC.

NOTES

31. 20% overrange on all ranges, except 2.4 k

Ω for the 10 kΩ range.

32. Maximum clamp voltages are DC, typical accuracy is ±20%. Add 20% for offset compensation on.

33. Relative to calibration accuracy.

34. Add per degree from T

35. Test current with offset compensation off.

36. Noise values are based on 1000 readings with autozero on and using low thermal 4-wire short.
