The frequency characteristics are good, but an indication error will increase for high frequencies. (See 8-3) Read the indication by multiplying 0 - 120 graduations by 10 in the 750 V range. Never perform measurement exceeding 750 V to ensure safety. After over voltage was applied, the meter will swing out for a while even if the input is removed, but this is not a problem, and the pointer will return to the zero position in a...
