Page 12: 10 ] Measuring Of Ac Voltage
[10] MEASURING OF AC VOLTAGE Measurement of 0 ∼ 1000V AC (auto range) Measurement of sine wave AC voltage below 1000V max. For safe measurement, never apply a voltage above 1000V AC. Never apply an excessive voltage (more than 100 times the maximum value of the applicable range) with the range held. -
Page 13: 11 ] Measuring Of Low Frequency Output(Db)
[11] MEASURING OF LOW FREQUENCY OUTPUT(dB) The dB value is scaled in the 3V AC range and only when the impedance is 600Ω, 0dB is equal to 1mW and the output value can be read directly. (0dB = 1mW = 0.775V at 600Ω) 1. - Page 14 0Ω setter(Refer to Fig. 6 in [16] MAINTENANCE) This tester employs the constant voltage method for measurement of resistance and there is no need of 0Ω adjustment for normal measurement. To cancel resistance of the test leads in measurement in the x 1Ω range, turn the 0Ω...
