4.2.4 RF Output Power
Equipment:
•Dual treadle foot switch.
•Bovie #12 adapter.
•Shorted return electrode adapter.
•Electrosurgical analyzer with 500 and 50 ohm
loads.
NOTE: Analyzers with 300 or 400 ohm loads
for monopolar and 100 or 125 ohm loads for
bipolar may also be used with some loss of accu-
racy due to load regulation variations. See Section
1.3.
An RF output power instrument may be con-
structed using a 500 ohm, 100W and 50 ohm
50W non-inductive resistors and a set of RF
ammeters ranging from 150 mA to 1.0 A full
scale. Fast blow 250V fuses rated at the meter full
scale current are recommended to prevent acci-
dental meter failure.
Procedure:
1. Use test leads to connect an RF ammeter in
series with the 100W resistor and one of the
unit's return electrode jack and the foot switch
controlled active jack.
2. Perform the monopolar power tests indicated
in Table 4.1 depending on the value of the load
resistor used.
3. Disconnect the RF ammeter and load resistor
from the unit.
4. Use test leads to connect the RF ammeter in
series with the 50W resistor and unit's blue
Bipolar Accessory Jacks.
5. Perform the bipolar power tests indicated in
Table 4.1 depending on the value of the load
resistor used.
Note: The RF output power level checks of Table
4.1 correct for the load regulation characteristics
of the Sabre 180. This results in output current
levels that differ from the power setting when the
P=I2*R calculation is done at other than the
rated load. Refer to the Load Regulation Curves
in Section 1.3 for details.
