5-2 Voltage Measurement (V)
Function
Max. Rated Input
Range
DCV DC 1000V
400.0mV, 4.000V, 40.00V, 400.0V, 1000V
ACV AC 1000V 4.000V, 40.00V, 400.0V, 1000V
Remarks:
This meter’s AC detection method is the average value method. It
indicates an average value of voltage or current in the positive half
cycle. No error will occur in measurement of waveforms when the
input waveform is sinusoidal wave with no distortion. However, if the
input waveform is distorted sinusoidal wave or non-sinusoidal wave,
an error will occur.
•The indication may fluctuate when the test leads are released. It is
not a failure.
• The AC400.0mV range can be selected with the 00000000 button,
but the accuracy is not guaranteed.
• In the AC4.000V range, when the measuring terminals are shorted,
7 counts maximum may remain indicated.
• The accuracy guarantee frequency range of ACV measurement is
40 Hz to 400 Hz.
If the frequency is above 1 kHz, measurement is not possible.
• It may malfanction when measuring voltage in the inverter circuit.
