Page 7: General Information Page
This device was built and tested according to CISPR 16-1-2. LISN has been supplied from the factory in a technical faultless state. LISN's from AFJ Instruments may use only on power supplies secured by fuses with prescribed safety devices. With no safety condition as:... -
Page 8: Construction
A further task of the LISN is the separation of the DUT from the mains concerning the high frequency interference's. Therefore the construction of the LISN LT32C/10 has a simulation impedance of: (50µH + 5 Ohm) // 50 Ohm. The term in brackets is the impedance of the LISN. -
Page 9: Technical Description Page
The compact form of construction, despite the high current-bearing capacity, makes easy use of the AFJ LISN LT32C/10 for the measurement of high currents directly at the piece of use of the consumer possible. In this way, measurements of mains-borne interferences can be carried out under conditions corresponding to practice. -

LISN, via the appropriate logic signal cable supplied. In such case, totally automatic control of the LISN can be achieved, via the instruments software interface. AFJ LISN LT32C/10 offers current meter to read and measure Switching Operations and EUT absorption current, as per CISPR 14-1 requirements (see Section E). -

Page 16: Switching Operation Page
Switching operations are defined in CISPR 14-1 as EUT supply current change; no other specifications are reported. AFJ LISN LT32C/10 offers current meter to read and measure Switching Operations and EUT absorption current, as per CISPR 14-1 requirements. Example of appliances for which the click rate N is derived from the number of switching operations: - Thermostats for room heating equipment;... - Page 17 It is important to keep all connections within the adapter as short as possible, to avoid measuring errors at high frequency.
