MAXIMUM OVERLOAD:

350V peak on nA ranges and 2μA range;

50V peak on 20μA, 200μA, and 2mA ranges.

Higher voltage sources must be current limited at 3mA.

INPUT VOLTAGE BURDEN:

<200μV (18°–28°C) for inputs <100μA;

<2mV for 2mA input; 20μV/°C temperature coefficient.

TEMPERATURE COEFFICIENT (0°–18°C & 28°–50°C):

±(0.15 × applicable accuracy specification)/ °C.

NMRR: >60dB at 50Hz (LINE 50Hz integration) or

60Hz (LINE 60Hz integration).

ANALOG OUTPUT:

Range: ±2V for full range input (non-inverting).

Accuracy: ±(2.5% + 3mV); resistive loads >2kΩ; 18°–28°C.

Impedance: <100Ω, DC–2kHz.

RANGING: Automatic or manual.

AUTORANGING TIME: <200ms to final range (analog filter OFF).
