Calibrating the Generator
5-30 Force FX Electrosurgical Generator C Service Manual
Adjusting the Clock
The hour and minute values are stored in the real-time clock on the Control board. The
clock was originally set for Mountain Standard Time. The clock is configured to the
24-hour (i.e., military time) format.
1. Verify that the Bipolar display shows calibration step number C3.
2. To select the hour, press the Coag up ( D ) or down ( Ñ ) arrow buttons until the
correct value (0–23) appears in the Coag display.
Examples:
• For 2 AM, set the hour value to 2.
• For 2 PM, set the value to 14.
3. To display the minute value, press the Med (Fulgurate) button.
4. To select the minute value, press the Coag up ( ) or down ( ) arrow buttons until
the correct value (0–59) appears in the Coag display.
5. To save the hour and minute values and go to the next calibration step, press the
Bipolar up arrow ( ) button.
Next, check the REM impedance as described in Check and Adjust the REM Oscillator
Frequency and Impedance.
Checking and Adjusting the REM Oscillator Frequency
and Impedance
Equipment required
• Oscilloscope
• REM plug (modified) or two small (24" [< 61 cm]) test cables
• Resistor substitution box
1. Verify the following:
• The Bipolar display shows calibration step number C4.
• The Coag display shows the letters OP (open circuit).
2. Calibrate the REM oscillator frequency:
a. Connect an oscilloscope across the Patient Return Electrode receptacle pins.
b. Remove the five screws that secure the cover to the chassis and lift the cover off
the chassis.
Warning
Electric Shock Hazard Do not touch any exposed wiring or conductive surfaces while the
generator is disassembled and energized. Never wear a grounding strap when working on an
energized generator.
