Wiring Precautions
To prevent the possibility of electric shock and damage to the instrument, please pay
attention to the precautions below.
Employ protective earth before connecting measurement cables. The power cord
that comes with the instrument is a three-pin power cord. Connect it to a properly
grounded three-pong outlet. Please cut off the power to the circuit and make sure
there is no voltage in it before touch a circuit.
Cut off the power to the circuit under measurement when wiring or disconnecting
the circuit. Connecting or removing measurement cables while the power is on is
dangerous.
Take special caution not to wire a current circuit to the voltage input terminal or a
voltage circuit to the current input terminal.
When strip the insulation cover of the measurement cables, make sure that the
conductive parts (bare wires) wired to the input terminal do not expose from the
terminal. In addition, tighten the screw of input terminal so that the cable does
not come loose.
Do not touch the input interface. When the measuring circuit is being applied to
the current input terminal, do not touch the current sensor input terminal.
Similarly, when the measuring circuit is being applied to the current sensor input
terminal, do not touch the current direct input terminal. Since these terminals are
electrically connected inside the instrument, the operation is very dangerous.
Withstand voltage of Potential Transformer and Current Transformer. When
using the external potential transformer (PT) or current transformer (CT), make
sure it has enough withstand voltage with respect to the voltage (U) being
measured. In addition, the secondary side of CT should not become an open
circuit while the power is on. If this happens, high voltage will appear at the
secondary side of CT, which is extremely dangerous.
For safety reasons, when mounting the instrument on a rack, a switch should be
furnished from the front side of the rack, which is used to cut off the circuit under
measurement.
Loop voltage and current. Ensure that the measurement circuit voltage and
current and common-mode voltage within the rated range of the instrument;
Connect external sensors. Do not use the bare metal BNC connector when
connecting external sensors. Remove all connections of the current direct input
terminals;
Current direct input. The connection of the sensor input terminal must be
disconnected;
Connect external shunts. The power supply of the measuring circuit must be cut
off. It is dangerous if not shut down the power or remove the shunt.

Notes: [1] Urms and Irms are true voltage and current rms value respectively. Each
instantaneous value in one period is squared and the result is averaged, then the resulting average
value is squared again. The equations are shown in Appendix B.
[2] Umn/Imn is the rectified mean value calibrated to the rms value. One period of the voltage
or current is rectified and the resulting average is multiplied by the factor that would yield the true
rms value if the applied signal were a sine wave. The factor is different from the value obtained in
RMS mode when distorted waves or DC waves are measured. The equations are shown in
Appendix B.
[3] Udc/Idc is defined as the average of one period of the voltage/current. This mode is useful
for determining the average value of a DC input signal or the value of a DC signal that is
superimposed on an AC signal.
[4] Urmn/Irmn is the rectified mean voltage/current. One period of the voltage or current is
rectified and the resulting average is obtained.
[5] Crest factor is defined as the ratio of the waveform peak value to the rms value.
[6] Waveform factor is defined as the ratio of the waveform rms value to the rectified mean
value.
PA5000 power analyzer can also use digital filtering to achieve an averaging process
when calculating the measured voltage or current values.
2.3 Operating Mode
The power analyzer includes several operating modes.
Normal Mode. This mode is used to measure voltage, current, torque, speed,
power, and implement integral operation and waveform calculation.
Normal Measurement and Analysis Mode. In this mode, the measured data
saved in the normal mode are replayed and analyzed so that users can observe
and analyze them conveniently.
Harmonics Mode. Harmonics measurement can be performed on a signal with
0.5Hz~5kHz fundamental frequency.
IEC Harmonics Mode. In this mode, users are allowed to perform harmonics
measurement conforming to the international standard IEC61000-3-2 and
IEC61000-4-7.
Voltage Fluctuation and Flicker Mode. This mode allows users to perform
voltage fluctuation and flicker measurements conforming to IEC61000-3-3 and
IEC61000-4-15. Users can also set measurement conditions themselves and
then create a report of measurement results.

FFT Mode. In this mode, the frequency spectrums of input signals (for example,
voltage (U), current (I), power (P) and Q) are displayed through FFT (Fast
Fourier Transform).
Cycle-by-Cycle Measurement and Analysis Mode. In this mode, the voltage,
current, power and other parameters of each cycle for AC input signal are
measured.
2.4 Voltage/Current Mode
Users can specify the calculation mode to display the calculation results for the
sampling data of voltage or current. The voltage/current mode determines the
calculation mode of the sampling data. Some measurement functions of the power
analyzer are related to the selection of the voltage/current mode. The voltage/current
mode includes five values as follows:
RMS: True RMS;
MEAN: Rectified mean value calibrated to RMS;
DC: Linear average voltage;
AC: Effective value ofAC component;
RMEAN: Rectified mean value.
2.5 Communication Interface
The power analyzer comes with USB, Ethernet, GPIB and RS-232 interfaces. Users
can remotely control the power analyzer through these interfaces, and can also
analyze the sampling data acquired by the instrument in detail and then create
reports.
In addition, the power analyzer provides audio input interface and audio output
interface on the front panel, as shown in Figure 2-1 and Figure 2-2.
