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:
 10 Ω at 0.2 PLC: 80 (from Accuracy table) + 230 (additional peak noise uncertainty) = 310 ppm of range

10 Ω at 1 PLC: 80 + 0 = 80 ppm of range

DRY CIRCUIT RESISTANCE CHARACTERISTICS
Maximum 4-wire ohm lead resistance
0.5 Ω per lead for 1 Ω range
10 % of range per lead for 10 Ω to 100 Ω ranges
50 Ω per lead for 1 kΩ to 10 kΩ ranges
Input current limit
For signals > [±20 mV], current limited, ±13 mA, typical
Offset compensation
Selectable on 1 Ω to 10 kΩ ranges
Autozero off error
For ±1 °C and ≤ 10 minutes, add ± 8 ppm of reading
36
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.
