*1. DT4254: DC 1700 V, AC 1000 V
Your instrument can be used to measure voltages in excess of 1000 V DC if and only if both of
the following conditions are satised:
1. The circuit under measurement is isolated from the commercial power grid.
2. The circuit under measurement is isolated from ground.
(Accuracy guaranteed for 1 year, post-adjustment accuracy guaranteed for 1 year)
