Maximum sense lead resistance 1 MΩ for rated accuracy

Voltage line regulation 0.01% of range

Voltage load regulation 0.01% + 100 μV

Current line regulation 0.04% of range

Current load regulation 0.04% + 100 μA

Recommended calibration interval One year

1. Drive 50% of 1 V or 10 V output with a resistive load. Rise time is from 10% to 90% of program voltage change at maximum current.

Fall time is from 90% to 10% of program voltage change at maximum current.

2. Measurements obtained are per default bandwidth setting.

NOTE

• All channels are isolated from the ground and from each other. Isolation is +60 VDC, Category 1.

• All specifications are based on a three-hour warm-up time.

• The measurement accuracy value is x ( 1 + a * y ), where,

◦ x = accuracy specification at room temperature,

◦ a = temperature coefficient, and

◦ y = temperature change from room temperature in °C

Noise 10 Hz to 20 MHz (Peak-peak)
