To customers using Model DT4254
Your instrument can be used to measure voltages in
excess of 1000 V DC if and only if both of the following
conditions are satisfied:
1. The circuit under measurement is isolated from
the commercial power grid.
2. The circuit under measurement is isolated from
ground.
e.g.: when measuring the no-load voltage of an
ungrounded PV panel
Do not use the instrument with circuits whose
terminal-to-ground voltage exceeds 1000 V.
Doing so may result in electric shock.
