SECULIFE ESPRO
INPUT ZERO – The Input Zero offset can be slightly different between RF donuts. This parameter
accesses an auto-zeroing function that eliminates this offset. Independent settings are saved for the
0.1:1 RF donut and 1:1 RF donut. The user can switch between the two donut types without having to re-
zero the input. The input needs to be zeroed only when a new donut is introduced.
INPUT RANGE
– The input range can be scaled to accommodate the signal that is being measured. The
input can be set to fixed ranges of 100mV Peak, 1000mV peak or Auto-Ranging. For Auto-Ranging
mode, the low range will be used for readings from 0.00 to 30.00 mV RMS. The high range will be used
for 20.0 to 700.0 mV RMS.
INPUT MODE
– There are two input modes to allow for measurement of continuous signals or pulsed
signals. In Continuous Mode, the input is updated every 100 mS. This mode should be used for all
Electrosurgical Generator waveform outputs in general use generators. A number of Electrosurgical
generator manufacturers offer generators with pulsed outputs, where there is a long duty cycle (typically
½-second or more) and the actual RF output of the generator is active for a brief period of time within the
duty cycle (typically 1/10
th
second or less). In Pulsed Mode, the input to the SECULIFE ESPRO is only
processed when a signal over 20 mV in amplitude is detected. The
SECULIFE ESPRO analyzes the
pulsed input waveform and can provide the RMS readings for either the overall input or the pulse only
(see Diagram 1, Page 15).
NOTE: When set to Pulsed
Mode, a small graphic appears in
the upper right corner of the
screen to identify to the user that
the
SECULIFE ESPRO is
looking for a pulsed RF input.
