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
