• *1: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:
• The circuit under measurement is isolated from the commercial power grid.
• The circuit under measurement is isolated from ground.
• 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 1000V.
