Ensure that the maximum voltage between the OUTPUT+ and SENSE+,
OUTPUT–, and SENSE– does not exceed 3 V.
Maximum change in output/readback per °C after a 30-minute
warm-up is 0.15.

NOTE
–– All channels are isolated from the ground and from each other. Isolation is +60 VDC, Category 1.
–– All specifications are based on three hours 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
