20.4 Internal Block Diagram of the 3193
The internal construction of the HIOKI 3193 is shown below. The broken
lines indicate options.
When the optional input units (9600, 9601, and 9602) are used, the voltage
(
U
), current (
I
), and active power (
P
) are converted to DC voltages by
analog computation in the input unit, and the waveform peak value is
detected by an analog peak hold function. Each of these DC voltages is
converted to a 16-bit digital value by an A/D converter in the input unit, and
transferred to the 3193 proper. The 3193 computes from these input values
the reactive power (
Q
), apparent power (
S
), power factor (
λ
), phase angle
(
φ
), current integration value (
Ih
), active power integration value (
WP
), load
factor (
LF
), and efficiency (
η
). The same process of conversion to a DC
voltage, transfer to the 3193 proper, and computation, occurs also for the
optional 9603.
For the optional 9605, the harmonics and flicker value are calculated by a
DSP within the 9605, and these results are displayed on the main unit.
