(1.0rdg + 6dgt)
Vmpp = Maximum power voltage, Impp = Maximum Power Current
(*) Max measurable value of Power must include FF value(~ 0.7) Pmax = 1000V x 10A x 0.7 = 7000W
(**) Test is stopped and the message “Thermal instability” occurs if the instrument detects Voltage > 700V and Current I >3A, I > -
