In Vdc 1000V range, 5% over-range (1050Vdc) is readable.
(4)
Input Impedance is in paralleled with capacitance <120pF.
•
••
• Maximum input voltage: 1000Vdc or peak ac on any range
•
••
• Response Time: Approximately 1.0 second when the displayed reading reaches 99.9% dc
value of the tested input signal at the same range.
Note: When voltage (ac+dc) measurement function is selected, the Vdc input impedance is
paralleled with an ac-coupled 1.1M
Ω ac divider.
