The ESU-2400 Series utilizes an internal current transformer and internal precision load
resistors for simple configuration of typical Electrosurgical Generator testing. Many of the
world’s leading Electrosurgical generator manufacturers utilize this exact same technique
when they test, service and calibrate their generators.
Internal configuration relays allow for simple connections to the DUT. When the Measure
RF Energy, Measure RF Leakage, or REM/ARM/CQM mode is selected from the main
menu, the relays configure the internal connections as required. Shown below are
examples of external connections to the DUT.
Monopolar:
1. Yellow Active Lead from Active Jack on ESU-2400 to DUT Output.
2. Blue Dispersive Lead from Dispersive Jack on ESU-2400 to DUT Dispersive.
