RMS NOISE (additional peak noise uncertainty)
36
• 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.
EXAMPLES:
• 10Ω at 0.2 PLC: 80 (from Accuracy table) + 230 (additional peak noise uncertainty) = 310 ppm
of range.
• 10Ω at 1 PLC: 80 + 0 = 80 ppm of range.

DRY CIRCUIT RESISTANCE CHARACTERISTICS
MAXIMUM 4-WIRE OHMS LEAD RESISTANCE:
0.5Ω per lead for 1Ω range.
10% of range per lead for 10Ω to 100Ω ranges.
50Ω per lead for 1kΩ to 10kΩ ranges.
INPUT CURRENT LIMIT: For signals greater than ±20mV, current limited, ±13mA typical.
OFFSET COMPENSATION: Selectable on 1Ω to 10kΩ ranges.
AUTOZERO OFF ERROR: For ±1°C and ≤10 minutes, add ±8 ppm of reading.
