Setup current peak limiter for surge current
The peak current limiter stops the test run when during a test the measured peak current of a surge pulse is
higher than the preselected current value. This safety function protects the EUT for further surge pulses that can
become any dangerous situation.
Depends of the different impedance of the surge generator, one current limiter for both impedances (2
, 12
) is
available.
Select SURGE Menu / Current Limiter
Set peak current limiters
I_D
= Current limiter Differential mode (line to line):
The generator impedance is 2
I_C
= Current limiter Common mode (line to ground):
The generator impedance is 12
REMARK
The current limits in Software and Manual operation are two individual settings.
Software
uses the
software settings
for I_D and I_C
Manual operating
uses the
device settings
for I_D and I_C
Note:
Surge pulses with the coupling position for data lines use the settings of common mode. This is general used for the
coupling network CNV 504 / 508 series with have an impedance of 42
(2
+ 40
).
Using a coupling network coupling NX-series uses the limits of differential and common mode.
