4-Wire Ohms (

≤10kΩ) Offset Compensation On

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

1 k

Ω at 0.006 PLC: 3 (from Accuracy table) + 26 (additional peak noise uncertainty) = 29 ppm of range.

1 k

Ω at 1 PLC: 3 + 0 = 3 ppm of range.

Add peak noise uncertainty to measurements for <1 PLC.

Examples

10 k

Ω at 0.006 PLC: 3 (from Accuracy table) + 5 (50 mΩ with Rel ) + 43 (additional peak noise uncertainty)

= 51 ppm of range.

NOTES

28. Open circuit voltage is typical, measured from input HI to LO, SHI and SLO open. For 1

Ω to 1 MΩ ranges using an external digital multimeter (DMM) set to 10 MΩ input impedance; for

10 M

Ω to 1 GΩ ranges, set external DMM to >10 GΩ 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.
