POST RF AC volt-
age coag feedback
too low (A/D chan-
nel 1)
Monitor senses
electrosurgical voltage out-
put too low during POST
test, indicating insufficient
voltage from HVPS, insuf-
ficient drive from the
RF Controller, failed RF
Amplifier, or a failed voltage
sensing channel.
The limits for this compari-
son are set when the system
enters calibration mode.
See above.

335
POST RF AC volt-
age coag feedback
too high (A/D
channel 1)
Monitor senses
electrosurgical voltage out-
put too low during POST
test, indicating insufficient
voltage from HVPS, insuf-
ficient drive from the
RF Controller, failed RF
Amplifier, or a failed voltage
sensing channel.
The limits for this compari-
son are set when the system
enters calibration mode.
See above.
See above.
336
Calibration RF AC
voltage cut feed-
back too high
Monitor senses
electrosurgical voltage out-
put too high during POST
test, indicating excessive
voltage from HVPS, exces-
sive drive from the RF
Controller, or a failed volt-
age sensing channel.
Check for proper performance
of the RF Amplifier, the HVPS,
and the voltage and current sense
channels.
Verify that all cables are properly
connected.
See above.
