1 SAFETY INSTRUCTIONS
INA 3425 calibration kit for EFT /Burst coupling clamp
is an accessory to be used with IEC 61000-4-4 Burst
generators and coupling clamps only. These type of
instruments generate high voltage peaks up to 4 or
even 8 kV. User manual and safety instructions of the
EFT / Burst generator needs to be followed during use
of this accessory.
INA 3425 together with the EFT/Burst generator and
coupling clamp should only be installed and used by
authorised and trained EMC specialists or calibration
engineers. (electrical engineers).
Personnel tted with a heart pacemaker must not
operate the instrument and must not be in the vicinity
of the test rig while it is in operation.
Risk of radiating electromagnetic interference. Test
equipment and test setup may need to be used in a
shielded environment.

Calibration kit for EFT / Burst Capacitive coupling clamp INA 3425
Burst / EFT pulse are High voltage low energy pulses
which will be applied to the top plate of the burst / EFT
coupling clamp- It is recommended NOT to touch the
top plate during the time pulses are applied. Up to pulse
voltages up to ca 1 kV the user will not notice anything
by getting in contact with the plates, up to 4 kV he will
notice some pain similar to what one feels during an
electrostatic discharge. Over 4 kV, up to 8 kV, the pain
will get worse – but stays undangerous for the normal
human being. TESEQ recommends the use of the safety
cover with Interlock for all applications using genera-
tors for more then 4 kV Burst pulses.

2.1 Intended purpose
The calibration kit for EFT / Bursts coupling clamps is designed for the calibra-
tion burst / EFT coupling clamps as specied in basic standard IEC 61000-4-4
Ed 3.0 : 2012
The INA 3425 consists in a transducer plate and a termination bracket (con-
nection adapter)

Calibration kit for EFT / Burst Capacitive coupling clamp INA 3425
2.2 Preparation for operation
The test rig is to be constructed in accordance with IEC / EN 61000-4-4 Ed 3.0 :
2012 with special reference to:
– Operation preferably in a screened room to protect the environment
– Distances to the EUT and peripherals to be as specied in the standard
– Good and large area contact to the earth plane
Fig. 2: Example of calibration test setup as described in IEC / EN 61000-4-4 Ed
3.0: 2012
2.3 Operating
– Set up Burst / EFT generator, oscilloscope and coupling clamp to calibrate on
an adequate ground plane
– respect setup as specied in IEC 61000-4-4 Ed 3.0: 2012
– Use CAS 3025 (INA 265A) to veriy the compliance of the reference burst / EFT
generator, save waveshape and register pulse parameters for reference.
– Place the INA 3425 into the coupling clamp to be calibrated – position the
whole as specied. Note that the Teseq sticker at the end of INA 3425 is placed
the way that when in line with the end of the coupling clamp , the distances
to the connecting adapter will automatically be < 10 cm as required by the
standard.

- Connect the delivered HV pulse cable to the pulse output of the used EFT/ Burst
generator. As shown in Fig 3

– Connect termination bracket (connection adapter) at the other end of the
coupling clamp to calibrate as shown in Fig 4
Fig. 4: connection of termination bracket (connecting adapter)
Note: insure good contacting of termination bracket to ground plane

– Connect CAS 3025 (or INA 265A – 50 Ω terminator / attenuator) and oscil-
loscope to the termination bracket as shown in Fig 5
Fig. 5: CAS 3025 (INA 265A – 50 Ω terminator / attenuator) and oscilloscope
connected to termination bracket.
– the whole test setup might look like shown in Fig 6
Fig. 6: complete test setup for Burst / EFT coupling clamp calibration
– set Burst generator to 2 kV
– measure burst pulse waveshape and parameters at Coupling clamp output.
– turn the Burst coupling clamp in the other direction in order to verify/ calibrate
the other path, and repeat the measurements.

6 MAINTENANCE AND WARRANTY
5.1 Maintenance and cleaning
Maintenance is limited to the removal of any foreign particles or objects from
the surfaces since such matter can adversely affect the test parameters.
In general a moist cloth is sufcient for cleaning the outer housing. In stubborn
cases use a small amount of a mild, non-foaming household cleanser as well.
No chemicals should be used for cleaning purposes.
5.2 Warranty
Teseq grants a warranty of 24 months against material and manufacturing
faults. The warranty does not cover damages due to transportation, poor pack-
aging, and those damages caused through use of the equipment for unforeseen
purposes and the effects of physical force.
5.3 Shipping
Always use original Teseq packaging, make sure the various warning labels for
delicate instruments are well visible.
