6-4-4 ACV (ACV p-p) Maximum measurable voltage AC 840 Vp-p
1) Objects of measurement
Voltages (p-p values) between maximum and minimum values
of sine wave and distorted wave alternating current.
Sine wave (frequency characteristics : See 8-3 )
Distorted wave (Range : 8.4 Vp-p range only, frequency
characteristics : 40 Hz - 50 kHz)
• Triangular-wave, square-wave over 20 % duty cycle, or
pursuant voltage with repetitive waveform.
• Triangular-wave, square-wave over 20 % duty cycle, or voltage
with half-wave retification wavefrom.
However, frequency must be in between 40 Hz - 50 kHz, and +
side of rectified voltage must be connected to +input terminal of
the instrument.
CAUTION
Above is only for measuring distorted wave voltage of 8.4 Vp-p
range.
The reading is approximate value when measuring non-sine
wave AC at range of 33 Vp-p or higher.
3) Measurement procedure
Insert the red plug of
test leads into the
+input terminal, and
the black plug into the
–COM terminal.
Turn the function/range
selector to the appropriate
ACV p-p range.
Turn on the power
switch (power ON:
Lamp blinks).
Turn the electrical zero adjuster (ZERO ADJ) to adjust the
pointer to the zero position of red ACV (p-p) scales.
Apply the red and black test pins to two measuring points
(parallel connection to the load). The polarity of test leads may
be ignored.
