Electrosurgery
Analyzer provides enough
user-selectable test loads
to do routine maintenance
checks on most electrosur-
gery units on the market
today. Compact and por-
table, the device is so
simple to use that techni-
cians can become proficient
with the RF303
RS
within
minutes.
The unit measures ESU
output and high-frequency
leakage, allows for verifi-
cation tests on the return electrode contact quality monitors, and has an
oscilloscope output for waveform viewing. Instantaneous output or select-
able sample times provide extra versatility. The instantaneous mode is
sufficient for most units, but if output readings are variable and require
stabilizing, the signal-averaging mode allows users to manually select two
additional, slower sampling times to produce an accurate average reading.
