Safety
1.1.
General
Read the following operations manual carefully. Pay special attention to both safety and operation details!!!
Observe all of these precautions to ensure your personal safety and to prevent damage to the test equipment of our product
range.
The test generator is designed according to IEC 61010 respectively EN 61010.
Symbols
WARNING Risk of electrical shock. Please read the related paragraph in the operating manual.
GROUND At this point the 2m ground cable must be connected.
Power mains supply
The equipment is intended to be operated from a power mains supply that will not apply more than 250Vrms between the
supply conductors or between either supply conductor and ground. A proper ground connection, through the grounding con-
ductor in the power cord, is essential for a safe system operation. This is related to the use of the dito with the optional pow-
er mains adapter type MAD. Never apply a generator's voltage to a connector which is not specified for that voltage range.
Grounding ESD setup
ESD testing can be performed with battery- or mains-powered simulators. For reduce the risk of electrostatic discharge to
the operator it is necessary to follow the rulers below:
- Use a proper grounding of the setup and ESD simulator
- Working as stated in the standard
- Follow the application guidelines in chapter 1.5.1 for a safe working
Grounding the generators
The generators are grounded through the power cord. To avoid electric shock, plug the power cord into a properly wired
receptacle where earth ground has been verified by a qualified service person. Do this before making connections to the
input or output terminals of the test equipment.
Also the 2m long grounding cable required by the IEC 61000-4-2 must be connected to the related grounding port (see un-
der Symbols) while the test is running. Without the protective ground connection, all parts of generators are potential shock
hazards. This includes knobs and controls that may appear to be insulators.
Use the Proper Power Cord
Use only the power cord and connector specified for your product. Use only a power cord that is in good condition.
Use the Proper Fuse
To avoid fire hazard, use only the fuse specified in the parts list for your product, matched by type, voltage rating and current
rating.
Do Not Remove Covers or Panels
To avoid personal injury, do not operate the generators without the panels or covers.
Do Not Operate in Explosive Atmospheres
The generators provide no explosion protection from static discharges or arcing components. Do not operate them in an
atmosphere of explosive gases.

1.2.
Before Use
Prior to power-on the equipment
- Before putting the instrument into operation, please check the equipment you have received for damage due to transporta-
tion. Check the single boxes as well as the generator itself for mechanical damage. In case of damages, please contact
the manufacturer before switching on the unit.
Damage due to transportation
- Prior to applying power, check if the selected supply voltage complies with the mains:
115V/230V ??
- Equipment of security class I which is supplied by an auto-transformer may be considered as follows:
If the equipment is powered by an auto-transformer, with a primary voltage higher than the secondary voltage, be sure that
the low-voltage end of the secondary part of the auto-transformer is connected with the neutral of the primary side.
Equipment of security class I with removable neutral or with mains plug:
It is only permitted to insert the mains plug in a mains socket with protective earth connector. It is not allowed to interrupt or
disconnect the protective earth connection.
Performance of measurements
-Each interruption or disconnection of the protective earth connection inside or outside the equipment may lead to a
dangerous situation. Intentional interruption is prohibited.
-Interconnections between such equipment or to others, e.g. for remote control by personal computer, may be done with
cables recommended or delivered by the manufacturer.
1.3.
Maintenance, Adjustments, Exchange of Parts
The generator does not include any parts or components needing special maintenance.
Electrical maintenance should only be performed by experienced, specially instructed technicians.
Generally, standard maintenance requires periodic cleaning of the instrument and verification and calibrations of the speci-
fied pulse parameters only.
ATTENTION
Only trained technicians are allowed to perform
service or maintenance work on these instruments.
-When removing the housing cover or other parts of the equipment, high
voltage parts may become exposed. High voltage and high current are potentially lethal.
-The generator includes high voltage capacitors, which may retain their charge. High voltage –High energy
-For service, repair, adjustment, or replacement, the generator covers have to be removed and the generator must be
disconnected from all power mains supplies.
-The user is not allowed to independently change or modify any EM TEST generator. For service and repair, only original
EM TEST parts and components must be used. EM TEST is not responsible for any accident or injury incurred through the
use of other parts or components.
-If maintenance or service work is necessary, it must be performed only by experts who are familiar with the existing
danger.
-It has to be assured that only fuses of recommended type and nominal current are used for replacement. It is not per-
missible to use repaired fuses.

1.4.
Failures and Over stressing
-If it is assumed that a safe operating mode of the equipment is no longer possible, the mains connection must be re-
moved and the equipment secured from unintentional use.
-An unsafe operating mode is characterized as follows:
-the equipment shows recognizable damages;
-the equipment is not working;
-the equipment has experienced severe transportation stress;
-the equipment has been stored in an unsuitable environment for some time.
Please exercise prudence in determining whether a device is unsafe or not.
1.5.
Danger during testing
ESD tests are immunity tests on electronic equipment or devices. These tests are potentially dangerous for the operator.
Therefore it is the responsibility of the user to avoid critical failures and risks to the environment and operator.
Long and distributed lines to the EUT are able to radiate a certain energy to their vicinity. Therefore it is also the responsibil-
ity of the user to decide whether it is allowed to conduct immunity tests in a given installation.
Test voltages above 500V may generate spark discharges. Therefore it is forbidden to test in an explosive environment.
National and international recommendations regarding human safety must be followed.
People with certain health conditions, e.g. with a heart pacemaker or similar device, should be excluded from testing.
-When setting up the test, national and international regulations regarding human safety have to be guaranteed.
Handicapped people, e.g. persons using peacemakers, are not
allowed to use this test instrumentation. Hazardous
radiation may influence these products.
1.5.1.
Power Mains Supply and Ground Reference.
EMC and High Voltage test setups must have a good decoupled and stable power mains supply.
Decoupling may be achieved by:
- Filtering
- The use of isolation transformers
By the use of isolation transformers, ground current detectors will not work as intended anymore.
EMC and High voltage test areas must include a clear ground reference strategy. All generators, CDN’s and LISN’s
must be connected directly and as short as possible to the ground reference.
The ground reference system must be connected to the Protective Earth (PE) connection of the laboratory.

1.5.2.
Discharge Modules and Grounding of dito
- A discharge module includes capacitors as required in the related standard. The user must take into account that a capaci-
tor is still charged. The charged energy is so low that there is no danger to life. The energy is lower as required in standard
IEC 61010.
- During the test, the discharge tip is at high voltage potential. Touching the discharge tip during a running test may cause
uncomfortable discharges to the operator. Due to the low energy there is no danger to life.
WARNING
Risk of electrical shock. Do not touch any metallic part at the discharge module.
The 2m grounding cable must always be connected to the dito during any operation.
Do not discharge the simulator into the air, because electrostatic charge
can discharge and shock the operator.
Risk of shock OK Risk of shock
Remarks to the correct application with ESD generators.
Earth cable not connected
The 2m grounding cable, which is required by the standards, must always been connected between ESD simulator and the
ground reference system. In case that the grounding cable is not connected, the discharge current of the simulator will flow
through the body of the operator and may cause uncomfortable discharges.
Discharge to the air
When discharge the ESD simulator to the air, all not grounded parts are charged and keep the charged load. When touch
the housing after such event it can happen that people are discharge the charged parts and get an electrical shock up to
some kilovolts.
Between the ditto and the hand surface is a stray capacitance. When the operator discharge an ESD impulse into the air the
stray capacitance generates a potential between the discharge module and the operator. The effect is a discharge to the
operator with return through the earthcable to the ESD simulator.

-For charge the rechargeable LiFePO4 PowerPack dito use only the CU ditto charger.
-The use of the old charger ACH may destroy the PowerPack dito.
-Do not open the charger. Repairs must only be done by the manufacturer.
Environment:
Batteries are hazardous waste. Put used batteries into a special container or bring them to a special recycling center.
1.5.4.
Danger from the Device Under Test (DUT)
The DUT may become dangerous due to the applied
high voltage or to the energy content of the test pulses.
Therefore, please pay attention to the following points during testing:
-As soon as the DUT ceases to operate as intended, the test must be stopped immediately.
-In the case of internal damage, high voltages might be exposed at any point of the DUT.
-Cables and connectors can be overloaded by high voltages or energies.
-Due to internal damage of components, explosion and fire may occur.
-Unintended use of the DUT may cause hazardous situations in the vicinity of the test setup.

ESD test setup as per IEC 61000-4-2
2.1.
Test setup
A correct test set-up is very important for a reproducible test
procedure, especially for ESD testing. The correct test set-
up as specified in the standard is mandatory. Some of the
most important points are the following:
1. Test table
The test must be performed on a wooden test table. On the table, a metallic plane of at least 1.6x0.8m must be used, the so-
called horizontal coupling plane HCP. The EUT has to be isolated by 0.5mm from this metallic plane.
2. Ground reference plane
The ground reference plane is located under the test table. It must exceed the projection of the horizontal coupling plane by
at least 0.5m on all sides and must be connected to the protective grounding system.
The horizontal coupling plane on the test table has to be connected to the ground reference plane by 2x470 kresistors
(EAS30).
3. Test generator
The test generator must be properly connected to the ground reference plane.
Important: The ESD simulator must not be connected to the horizontal coupling plane.
The discharge unit 2m ground cable must be connected to the ground reference plane and not to the horizontal coupling
plane.

ESD test with Test Routines
1. Press the Start button for run the test procedure.
dito shows the position of the actual test
point for testing by a blinking TP 1. This
means, the tester must start with testing
the test point 1.
After 10 discharges dito shows in the
display a blinking TP2 to continue testing
the next test point.
dito will guide the user through the test.
2. Begin with discharging at Test point 1. The discharge starts with pressing the trigger button.
3. Events as Fail 1, Fail 2, Next must be documented by writing a comment in the test notes ( created with the esd.control
software.
Stop The running test is stopped .
<< (Redo) Repeat the test at the actual test point. Fail1 or Fail 2 information will be deleted and the test level is set
back to the starting level.
>> (Next) Change to the next test point or test level. dito shows on his display as example : Report Break : Nr
Fail 1 Fail 1 ( The criteria for this fail must be defined by the user )
Fail 2 Fail 2 ( The criteria for this fail must be defined by the user )
If you want to print the test notes please make indicate informations about the abnormal reaction of the EUT.
4. Terminate the test with the Stop button or dito stops automatic after the last discharge on the last test point.
5. Note the displayed Date and Time in your test notes.
