3.2 Analysis Channel Selection
You can select three input unit channels for harmonic analysis from the
input units (maximum three channels) in the 3194. If the frequencies are the
same, analysis on three single-phase channels is possible.
1. Press the STATUS key, then use the PAGE keys
to move the cursor to "HARM," to display the
harmonic measurement setting screen. This
displays the selected wiring mode.
2. Use the CURSOR keys to select the "WIRING"
item.
3. Move the cursor to the channel to be analyzed
with the CURSOR keys, then press the F1 "SET"
key to complete the setting.
･The channel selection is always of adjacent input units, corresponding to the
wiring modes set on the 3194 product. If the 3194 product wiring mode is
set to 3P3W for each of channels 1 and 2 and channels 3 and 4, then the
selection becomes channels 1, 2, and 3. In this case, the third channel is
treated as single phase for analysis.
･Up to three channels can be selected; a single-channel analysis specification
is not possible.

────────────────────────────────────────────────────
3.3 PLL Source Setting
────────────────────────────────────────────────────
NOTE
3.3 PLL Source Setting
A PLL source is required for analysis, and may be provided in one of the
following three ways.
(1) Input voltage or current serves as the source:
Waveforms are sampled at a frequency synchronized with the measured
voltage or current waveform to facilitate correct measurement.
(2) Internal fixed clock [Clock] frequency serves as the source:
Use this options when the input signal is not suitable as a source of PLL
synchronization, and the fundamental frequency of the signal for analysis is
50 Hz. In this case, measurement accuracy cannot be assured at frequencies
other than integer multiples of 50 Hz.
(3) An external sync signal [Ext(CH6) or Ext(Con)] serves as the source:
PLL-synchronized measurements for harmonic analysis can be made using an
external signal other than the input voltage or current waveform. Refer to
Section 4.7, "Measurement using an External Sync Signal."
The PLL indicator at the upper right of the screen appears when the PLL is
unlocked, and is not visible when the PLL is locked. The source setting for
frequency measurement shares the same indicator.
1. Press the STATUS key, then use the PAGE keys
to move the cursor to "HARM," to display the
harmonic measurement setting screen.
2. Moving the cursor to "PLL SOURCE" with the
CURSOR keys displays the settings available for
the PLL source in a window.
3. Use the F1 "↓" and F2 "↑" key to specify the
required item.
･If the signal selected for the source setting is very distorted, if the level is
low for the range setting, or the signal frequency is not stable, the PLL
circuit may not function. In such cases accurate analysis is not possible.
･If the three channels selected in Section 3.2 are separate systems with
different signal frequencies, the analysis results are only valid for the channel
for which the PLL source is set.

3.4 Wiring Conversion Function
────────────────────────────────────────────────────
NOTE
3.4 Wiring Conversion Function
This function calculates equivalencies for 3V3A and 3P4W wiring (refer to
Appendices 6 and 7).
・For 3V3A wiring, calculates Δ-Y conversion to 3φ4W equivalent wiring.
・For 3P4W wiring, calculates Y-Δconversion to 3φ3W equivalent wiring.
Press the STATUS key, then use the PAGE keys to
move the cursor to "HARM," to display the
harmonic measurement setting screen.
・Δ-Y conversion calculation uses a virtual neutral point.
・High-harmonic analysis can begin after waveforms have been converted.

9
────────────────────────────────────────────────────
3.5 Setting the Coupling Mode
────────────────────────────────────────────────────
NOTE
3.5 Setting the Coupling Mode
For the channel of which the analysis results are shown on the screen only,
press the SHIFT key then use the CURSOR key to switch.
It is also possible to change the setting in the STATUS/Units screen.
Refer to Section 4.2, "Setting the Coupling Mode" in the instruction manual
of the 3194.
･When AC mode (coupling mode) is selected on the 3194 product, a DC
blocking filter is required on the input unit. Therefore, if the measurement
frequency is 10 Hz or below, or the waveform has a superimposed DC
component (e.g. a half-wave rectified signal), errors may become large.
･Analysis results in the DC mode and analysis results in the AC+DC mode
are the same.
･When the AC+DC or DC mode is selected, a value is shown with a
harmonic index of "0." This shows the DC component included in the
analysis data. However, the polarity is not displayed for the voltage and
current since the effective value is converted.

10
────────────────────────────────────────────────────
3.6 Zero Adjustment Operation
────────────────────────────────────────────────────
NOTE
3.6 Zero Adjustment Operation
Zero adjustment must be carried out after warming up.
1. Press the STATUS key, then use the PAGE keys
to move the cursor to "HARM," to display the
harmonic measurement setting screen.
2. Move the cursor to "WIRING."
3. Press the F5 "ZERO ADj" key to start zero
adjustment.
･The operation is carried out for 3 channels simultaneously.
･The operation takes about 3 seconds.
･Carry out the operation with no inputs on either voltage or current.
･Carry out the operation after degaussing (DMAG) when using the 9600 or
9602.

11
────────────────────────────────────────────────────
3.7 Averaging Setting
────────────────────────────────────────────────────
NOTE
3.7 Averaging Setting
Analysis data is averaged in the 9605-01.
1. Press the STATUS key, then use the PAGE keys
to move the cursor to "HARM," to display the
harmonic measurement setting screen.
2. Move the cursor to "AVERAGE"
3. Select the item (amplitude or phase angle) to be
averaged.
Data other that required on the 9605-01 is not affected.

12
────────────────────────────────────────────────────
3.8 Measurement by External Trigger
────────────────────────────────────────────────────
NOTE
3.8 Measurement by External Trigger
By setting an external trigger, analysis can be started when the trigger signal
is input. One window of analysis data is displayed, then the process stops.
By synchronizing the timing with an external device, a number of 3194
products can perform analysis simultaneously.
1. Press the STATUS key, then use the PAGE keys
to move the cursor to "HARM," to display the
harmonic measurement setting screen.
2. Use the CURSOR keys to select the "EXT TRIG"
item.
3. Press the F2 "ON" key, putting the product on
hold for a trigger.
When a trigger signal is input from the outside,
analysis starts.
･The analysis always starts from a point at which the PLL source waveform
crosses the zero value, and there is therefore a delay of a maximum of one
cycle of the waveform with respect to the trigger signal.
･This does not affect data on the 3194 product (other than the 9605-01).
･The PLL should be locked.
