Dear Client
Thank you for Purchasing our SMG3000 Three Phase
Voltammeter. Please read the manual in detail prior to first use,
which will help you use the equipment skillfully.
Our aim is to improve and perfect the
company's products continually, so there may be
slight differences between your purchase equipment
and its instruction manual. You can find the changes
in the appendix. Sorry for the inconvenience. If you have further
questions, welcome to contact with our service department.
The input/output terminals and the test column
may bring voltage, when you plug/draw the test wire or
power outlet, they will cause electric spark. PLEASE

I. General Introduction
SMG3000 Three Phase Meter a high precision instrument
for measurement of three-phase electric parameters, it can be
used to measure the three phase voltage, current and phase
angle, frequency, power, power factor and so on.
SMG3000 Three Phase Meter adopt high-speed Cortex
M3 processor and 24 bits high-speed ADC a for measuring
and calculation , A complete graphical interface, true color
display with resolution of 320 x 240 and touch screen operation
make a friendly man-machine interface. It is easy to carry.
II. Main Functions

V. How to Measure
1. ON and OFF
Press the buttons continuously and enter the boot
screen as the following chart:
Figure 4 Boot screen
Press the buttons for 3 seconds and listen to a “tick”

sound, then the meter will enter the true state of boot.
2. Measurement Interface
It appears the measurement interface automatically when
the meter is on:
Figure 5 Volt-ampere phase measurement interface
If measurement methods choose three-phase three-wire,
lightly touch icon with the touching pen and the icon
will become , single-phase measurement can be
realized with the same operation.
This meter has data hold and storage function, lightly
touch icon, icon color turns from gray into red
as . Data measurement stops and then appears save
icon, lightly touch save icon and store the data. Circulation
storage is used; new stored data will deleted the first saved
data automatically.
Checking function can help to check the stored data, with
purple icon R * * (* * represents 01 and 02... 10), use the

- 13 -
previous page icon and the next page icon
to scan the data. These functions above are as effective in
power measurement interface.
Press the icon , icon turns to blue as the figure
shows below, the volt-ampere phase measurement date can
also be saved when you click save bottom.
Figure 6 Power measurement interface
Lightly touch vector diagram icon and enters hexagon
vector diagram measurement interface, the hexagon diagram
shows the voltage and current vector diagram by color (A
phase voltage and current in yellow, B phase voltage and
current in green, C phase voltage and current in red).
Judge phase sequence:
Green mark is shown before the voltage value if voltage
phase sequence is right; red mark is shown if wrong.
Green mark is shown before the current value if current
phase sequence is right; red mark is shown if wrong.

Judge load properties:
"L" is shown if it is inductive load; "C" is shown if it is
capacitive load, otherwise shows "-".
VI. Measuring Methods
1. One-Way Measurement Connection Mode
As following:
Figure 7one-way measure connection modes
Live line will be connected to the UA phase of the
instrument, while zero line is connected to UN when use
single-phase electric measurement. Current clamp sensor
should be clamped to live line and insert IA access.
2. Three-PhaseThree-Wire Connection Method
As following:

Figure 8 Three phases three lines connection method
Connection for pressure-wire: Use the special voltage
testing lines (three groups as yellow, red and black); one end
insert the UA, UC, UN phase socket of the equipment in turn,
and the other end insert the A phase, C phase and B phase of
the circuit being measured respectively.
Note: yellow line joins UV socket, black line joins UN
socket, and red line joins UC socket.
Connection for current line: Insert IA, IC clamp to IC, IA
socket of the equipment, and clutch the other end to the
current circuit being measured.
3. Three-Phase Four-Wire Connection Method
As following:

Figure 9 Three-phase four-wire connection method
Connection for pressure-wire: Use the special voltage
testing lines (four groups as yellow, green, red and black); one
end insert the UA, UB, UC, UN phase socket of the equipment
in turn, and the other end insert the A phase, B phase, C phase
and zero line of the circuit being measured respectively.
Connection for current line: Insert IA, IB, IC clamp to IA, IB,
and IC socket of the equipment, and clutch the other end to the
current circuit being measured.
