1.General
1.1 Power Quality Analysis
With this analyser you have acquired one of our high-quality, efficient and durable
multiple purpose test instruments. We thank you for your confidence.
By monitoring the voltage quality criteria, the final customer receives important
information about the quality of his power network as provided by the electricity
producer. With this Analyser you obtain the certainty that the power quality
corresponds to the EN50160 standard.
It is necessary to check the supply voltage regularly in order to ensure the perfect
functioning and working of the growing number of electronic devices. In connection
with the liberalisation of the energy market "Voltage Quality" is also becoming more
important for energy producers and final customers.
This device has been optimised for the fast identification of disturbances in the
power network.
With the help of the clear representation of all relevant parameters, it becomes
simple to detect systematic network problems.
Therefore the analyser was developed in particular for plant electricians and
electrical installers, who have an important role during the recovery of disturbances
of the power distribution system.
NOTE: FLASH TECHNOLOGY
Your Analyst 3P is equipped with Flash Technology. This enables you to perform
firmware updates. Please use the Windows Flash Update utility to do this. You will
find it on the Analyst CD-ROM.
Please find the most recent firmware - which is compatible to your instrument's
hardware - on the LEM Homepage.

1.2 Safety Instructions
Please read this section carefully. It makes you familiar with the most
important safety instructions for handling your device.
Important
This power quality analyser may only be used and handled
by qualified personnel.
Protect the device against wetness and humidity, so that
the device does not suffer damage.
The plug and socket connection for the voltage input is
designed for 600V CAT III. The maximum voltage between
outer conductor and earth potential must not exceed 600V.
With multi-phase connections, the voltage between the outer
conductors of the system to be measured may not exceed
800V.
Warning
Current probes must comply to IEC 61010-2-032 category A
and must be designed for 600V CAT III. If flexible current
probes are used, the conductor to be enclosed by the probe
and the adjacent conductor must be connected strain-free,
or suitable protective gloves must be worn.
Warning
Open the device only to replace the accumulator package
(see chapter 4.1). Opening the device can lead to electrical
shocks. Therefore the device has to be separated from all
live sections before opening. Also disconnect all test leads
before using the RS232 interface. Maintenance work can
only be done by qualified service personnel.

General
Analyst 3P 7
EO 0620GDF Rev. E
Warning
When connecting current circuits, the corresponding
measuring lines must first be connected to the base unit and
then to the current sensor to prevent the risk of electric
shock in case of false connection.
Please use only the provided original accessories.
Especially the original power adapter must be used since it
is a safety-relevant component! Please use only the supplied
original adapter.

2.4.2 Parameter Configuration
- Recording Adjustments (available in Hold mode only)
If you call the recording menu, then you can
select between two further submenus: Menu
for adjusting the averaging time (figure above)
and for adjusting the event threshold (figure
below) in recording adjustments.
In the menu “Averaging Time” you select the
time over which the measuring data are to be
averaged. You can also select these values
from the predefined values for averaging time.
With “Custom Setting” you can choose any
averaging time value. Depending upon the
selected averaging time, maximum available
recording time is indicated in the display at the
same time. Up to 1440 averaging intervals can
be recorded with the record function.
By selecting the menu “Event Thresholds” you
can select the threshold voltage at which the
recording is to be started (see also chapter
3.6).
- View/Delete Screenshots
Select one of the saved screenshots. Press
ENTER to view it. All screenshots include the
date and time and the measuring mode, in
which they were saved. Each page lists 10
events.
Use the to change the page.

- View Auto Screenshots With this menu item, you can view the
screenshots of a recording session,
which have been automatically saved
in the Save mode. 6 screenshots are
available (01...06).
Select one of the pictures with the
cursor key and press ENTER to view
it.
Note: Saved Auto Screenshots
always show the currently displayed
parameters.
Example: If you selected phase L2 in the Volt/Ampere/Hertz function and
the recording reaches the margin of the picture, a screenshot of the current
picture, i.e., phase L2, is saved.
- Display Contrast
Select the display contrast optimal for you with ´ ´.
- Instrument Set-Up
In this menu option you can make adjustments in the submenu for:
-Current probes - Version number
- Voltage probes - Background lighting
These are described individually in the following:
Current Probes
If you do not use standard accessories,
which are automatically detected during
start-up, you can make the necessary
adjustments here. Select one of the given
transducer types with “Type”. Enter the
transducer factor, through selection of a
given value or by input of a customized
value, e.g.: for a current probe displaying
0.5V per 5A this equals 100mV/1A.
Therefore, 100 should be entered.
Note: We recommend the use of standard accessories since it makes the
operation easier and clearer.

Voltage Transformers
If you use voltage transformers, select transducer factors with ENTER. Press
the key and enter any transformer factor with .
For transducer factor details see information on the voltage transformer.
Backlight
Here, you have the possibility to select whether the background lighting is to
deactivate itself automatically after 30 seconds or whether you want to
always deactivate it manually after switching it on with the ´ ´ key.
Note:
If the battery is in use, use the background lighting only if necessary. This
will ensure a longer battery life time.
Version & Calibration
This menu serves for your information. No adjustments can be made. The
displayed data give information of type and version of the device.
- Power Network
Select the used power network
topology (Y or Δ) here. Likewise you
can determine the nominal phase
voltage of the power network, its
nominal frequency and the current
range.
- Date & Time
Here you can enter the current date and the current time.
- Language
Here you can select the language with which you want to operate.

Measuring Functions
Analyst 3P 21
EO 0620GDF Rev. E
3. Measuring Functions
3.1 Overview
Now we will give you a short overview of the different measuring
procedures for the exact analysis of the power system, which is to be
examined.
Volts / Amps / Hertz
This function displays the voltage and current values at the same time, as
well as their frequency and the neutral-conductor current. You can also use
this measuring function to get an overview of these values, before you
analyse the signal in detail by means of the remaining functions.
Waveforms
This measuring function shows the voltages, currents and the ϕangle in
"oscilloscope representation“ as well as their instantaneous values at the
cursor position. With this function you get a clear representation of current
and voltage waveforms and their distortions.
Harmonics
Harmonics are sinusoidal voltages with a frequency, which corresponds to
an integer multiple of the fundamental of the mains voltage.
Every signal can be split into an infinite number of sine waves of different
frequency and amplitude. The contribution of each of these individual sine
waves is represented in a bar chart up to the 40th harmonic. The smaller the
harmonics are (starting from the 2nd harmonic, the 1st is the fundamental)
the better is the power network quality.
Power
This function indicates the values of the transferred power. At the same
time you can measure active power, reactive power, apparent power,
distortion power and the appropriate power factor. You can also view the
active and reactive power energy.
