SHO RT FOREWORD
Dear T1000 PLUS user,
I often wondered why the user’s manual is not very much
used, even if it includes valuable information. As me too I am
a user of such manuals, the answer I have given myself is that
valuable information are concealed somewhere in the thick
thing, and I do not have time to waste to find it. So, either the
manual is actually of help, or I ignore it.
This is why I decided to split the T1000 PLUS manual in three:
specification, with all performance details; application manual,
with instructions about how to use it one its operation is
understood; introductory guide, with the device description
and basic information. The idea is that you may read once the
introductory guide or the specification, while you need to
follow application examples more than once; so, why not to
split the manual in three?
Have a good work with T1000 PLUS!
Primo Lodi
Q&A Manager

SAFETY AT WO RK
The Product hereafter described is manufactured and
tested according to the specifications, and when used for
normal applications and within the normal electrical and
mechanical limits will not cause hazard to health and safety,
provided that the standard engineering rules are observed
and that it is used by trained personnel only.
The application guide is published by the Seller to be used
together with the Product described in the corresponding
document. The Seller reserves the right to modify the guide
without warning, for any reason. This includes also but not
only, the adoption of more advanced technological solutions
and modified manufacturing procedures, and also the addition
of other features, not available in the first release.
The Seller declines any difficulties arising from unknown
technical problems. The Seller declines also any responsibility
in case of modification of the Product or of any intervention
not authorized by the Seller in writing.
The warranty includes the repair time and the materials
necessary to restore the complete efficiency of the Product;
so, it does not include other burdens, such as the transport
and customs fee. Under no circumstances the warrantee
includes any cost that the User may have suffered because of
the Product unavailability and downtime.
The Product is CE marked, and has been tested to operate
according to EN 61010-1, with the following operating
conditions:
. Pollution degree 2: normally, non conductive pollution
occurs;
. Measurement category 2, for measurement inputs.
Would the test set be used beyond these limits, the
safety of the test set could be impaired.

DOC. MIE91093 Rev. 1.34 Page 9 of 145
Mains supply characteristics are:
. Voltage: 230 AC, 50-60 Hz, or 110 VAC, 50-60 Hz;
. Power consumption: 1 kW maximum.
. The symbol
!
is related to dangerous input or
output, and is located close to the following points:
- Outputs: main 0-250 V AC (500 V for E model); auxiliary 0-
250 V AC (500 V for E model); auxiliary 20 –260 V DC;
- Inputs: AC voltage measurement (up to 600 V); START and
STOP Inputs (up to 250 V); resistors (up to 250 V).
. The symbol is located closet o the round socket.
. The symbol is located close to the mains supply
socket, that incorporates the protection fuse.
The Product generates voltages and currents that may be
lethal to the unadvertised user. Besides, in order to avoid any
danger in case of fault inside the Product, the device under
test should have the following characteristics:
. Connection cables must use safety banana sockets;
. Connection sockets must be not accessible;
. Input circuits must have an isolation degree at least equal to
the one of the product.
DO NOT OPERATE THE PRODUCT IF NOT CONNECTED TO
GROUND: BECAUSE OF FILTER CAPACITORS, THE CASE
WOULD GROW TO A VOLTAGE EQUAL TO THE HALF OF
THE SUPPLY, I.E. 110 V (or 55 V). BESIDES, IN THIS
SITUATION THERE IS NO FILTERING AGAINST
COMMON-MODE NOISE COMING FROM THE MAINS: THIS
CAN CAUSE SUDDEN FAULTS. THIS TYPE OF FAULTS IS
NOT COVERED BY THE WARRANTY.
The connection to ground is provided through the mains
supply cable; however, for added safety, the Product should
be connected to ground using the dedicated socket.

DOC. MIE91093 Rev. 1.34 Page 10 of 145
IF THE GROUND IS NOT AVAILABLE AT THE MAINS
SUPPLY, CONNECT THE TEST SET TO GROUND USING
THE DEDICATED SOCKET.
In case of doubt, please contact your Seller. The Seller, and
Manufacturer, declines any and all responsibility due to
improper usage, or any usage outside the specified limits.
