4.5.3 Output Power

Equipment:
Monopolar Foot switch
Bipolar Foot switch
0-1.5A RF Ammeter as a minimum. The most
accurate RF current measurements will result
when read on the upper 50% of the meter scale.
A set of meters including 150mA, 250mA,
500mA, 1.0A and 2.0A are recommended.
300, 400, or 500 ohm 250W noninductive resis-
tor
50, 100, or 125 ohm 50W noninductive resistor
Return Electrode Adapter Plug (shorting)
Bovie #12 Adapter Plug
3 test leads, 1m max. length
Procedure:
1. Use test leads to connect an RF ammeter in
series with the 250W 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 the 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 2400. This results in output cur-
rent levels that may be different from the power
setting when the P=I 2 *R calculation is done
at other than the rated load. Refer to the Load
Regulation Curves in Section 1 for details.
