Introduction
Power quality analyzer adopts DSP＋ARM dual processor hardware platform and
embedded operation system (uClinux), which can calculate a large number of
electrical parameters and process all data quickly. The device offers extensive and
powerful measurements functions to check power distribution system, so it can detect
quality of power grid and electrical characteristics rapidly and conveniently. The
analyzer has large-screen color LCD display interface, and easy-to-use keyboard.
Main features:
Waveform real-time display(4 voltages/4 currents)
Half cycle RMS measurement (voltage and current)
intuitive operation
variety of optional current clamps
Measure DC component
Measurement of harmonics can be up to 100 times.
Transient capture
Vector, Trend, Bar Graph and events table display
Active power, reactive power, apparent power and energy, shift power
factor and true power factor
Three-phase unbalance (voltage and current)
Flicker
Inrush current
Detection and record of Dips& Swells, Voltage Rapid Change,
Interruption.
Detect according to EN50160 or grid with user-defined limit.
data storage and screenshots (can be replayed or output to a PC)
Through the LAN interface PC can keep real-time remote
communication with the Analyzer, operate the Analyzer and download
measurement data.
Built-in 32G memory card.
WIFI communication is supported.

General Safety Information
The Analyzer is designed and produced according to IEC61010-1 strictly, and
complies with CAT III 1000V, CAT IV 600V and pollution degree II. Learn about below
safety precautions to avoid personal injury, and damage to the Analyzer or any other
products connected to it.
To avoid electrical shock or fire:
Review the manual before use of the Analyzer and its accessories.
Read all instructions carefully.
Avoid working alone.
Do not operate the Analyzer around explosive gas, vapor or moist
environment.
Use the Analyzer as specified, or the protection provided by the Analyzer
might be impaired.
Use only insulated current probes, test leads and adaptors as supplied with
the Analyzer, or indicated as suitable for the Analyzer.
Keep your fingers behind the finger guard on the probes.
Before use, inspect the Analyzer, voltage probes, test leads and accessories
for mechanical damage and replace when damaged. Look for cracks or
missing plastic. Pay special attention to the insulation surrounding the
connectors.
Verify operation of the Analyzer by measuring known voltage.
Remove all probes, test leads and accessories that are not in use.
Always connect the power adapter first to the AC outlet before connecting it
to the Analyzer.
Do not touch high voltage: voltage>AC RMS 30V, or DC 60V.
Use the ground input only to ground the Analyzer and do not apply any
voltage.
Do not apply input voltage above the rating of the Analyzer.
Only use correct measurement standard category (CAT), rated voltage and
current probes, test lead and adapter for measurement.
Do not apply voltages in excess of the marked ratings of the voltage probes
or current clamps.
Comply with local and national safety standard. In dangerous environment
where the live wires are exposed, personal protection equipment such as
Power Quality Analyzer User’s Guide

approved rubber gloves, facial protection and flame-retardant clothing must
be used to prevent electric shock and arc discharge damage.
Pay special attention when connecting or removing flexible current probes:
power down the device being tested or put on suitable protection suit.
Do not insert metal objects into connectors.
Use only power adapter provided by the Analyzer.

charging indicator color changing from red to green, it reminds user the battery is fully
charged. The Analyzer automatically cuts off charging when the battery is fully
charged. Before use, check that the adapter voltage and frequency range match the
local line power range. To prevent decrease of batter capacity, charge it at least twice
a year.

1.3 Input Connections
The Analyzer has 4 BNC-inputs for current clamps and 5 banana-inputs for voltages.
For a 3-phase system, make the connections as above picture show.
First put the current clamps around the conductors of phase L1/A, L2/B, L3/C and N.
The clamps are marked with an arrow indicating the correct signal polarity.
Next make the voltage connections: start with GND and then succession N, L1/A,
