Correcting a High Impedance Condition
If a high impedance value is detected during RF power delivery, follow these steps:
1.
Ensure that the connection between the Catheter and XP APM is correct and secure.
2.
Ensure that the connection between each DIP Electrode and XP APM is correct and
secure.
3.
Ensure that each DIP Electrode is properly applied.
4.
If an improper cable connection is not the cause of the high impedance value, then a
build-up of coagulum on the Catheter tip may be the cause, and RF power output
should be discontinued.
5.
To discontinue RF power delivery, refer to the instructions in section,
Turning the
RF Power Delivery “OFF”
on page 6-19.
TIME Display
This display shows the user-selected value and elapsed time as follows:
•
When the RF POWER CONTROL Button is pressed or the Footswitch is depressed,
this display changes from the user-selected time limit to 0 seconds and begins to
count up to the user-selected value.
•
When the preset duration has elapsed, the RF power automatically shuts “OFF.” The
user-selected value remains flashing on the TIME Display.
•
If the RF POWER CONTROL Button is pressed during delivery of RF power or the
Footswitch is released, the RF power output immediately turns “OFF.” The actual
elapsed time in seconds remains flashing on the TIME Display.
COUNTER Display
This display increases by 1 count with each RF power delivery. This value resets to zero
at any time when the Controller is in the READY mode.
CONTROL Display
This display indicates the Controller’s current control mode (Power Control or
Temperature Control). The green LEDs indicate when the Controller is either in the
Power Control or Temperature Control modes, respectively.
