• Applies to ± ppm of range.
• Peak noise uncertainty is included in DC specifications for ≥1 PLC.
• Add peak noise uncertainty to measurements for <1 PLC.
EXAMPLES
• 1kΩ at 0.006 PLC: 3 (from Accuracy table) + 26 (additional peak noise uncertainty) = 29 ppm
of range.
• 1kΩ at 1 PLC: 3 + 0 = 3 ppm of range.

EXAMPLES
• 10kΩ at 0.006 PLC: 3 (from Accuracy table) + 5 (50mΩ with Rel ) + 43 (additional peak noise
uncertainty) = 51 ppm of range.

RESISTANCE CHARACTERISTICS
MAXIMUM 4-WIRE OHMS LEAD RESISTANCE: 5Ω per lead for 1Ω range, 10% of range per lead
for 10Ω to 1kΩ ranges; 1kΩ per lead for all other ranges.
OFFSET COMPENSATION: Selectable on 4-wire, 1Ω to 100kΩ ranges.
OPEN LEAD DETECTOR: Default is off.
AUTOZERO OFF ERROR:
For 2-wire ohms, ±1°C and ≤10 minutes, add ±(8ppm of reading) + 1.5mΩ for 10Ω, 15mΩ
for 100Ω and 1kΩ ranges, 150mΩ for 10kΩ range, 1.5Ω for 100 kΩ range, and 15Ω for all
other ranges.
For 4-wire ohms, ±1°C and ≤10 minutes, add ±(8ppm of reading).
INPUT CURRENT LIMIT:
For signals with a magnitude of +12V to +40V or –12V to –40V: ±13mA source or sink, typical.
For signals with a magnitude of greater than +40V or –40V: ±130µA source or sink, typical.

28. Open circuit voltage is typical, measured from input HI to LO, SHI and SLO open. For 1Ω to
1MΩ ranges using an external digital multimeter (DMM) set to 10MΩ input impedance; for
10MΩ to 1GΩ ranges, set external DMM to >10GΩ input impedance.
29. Noise values are based on 1000 readings with autozero on and using low thermal 4-wire short.
RMS noise is typical. Additional peak noise is guaranteed.
30. With line sync on.
