212 Generator not calibrated Refer to Calibrating the Generator on page 5-26.

Calibrating the Generator
There are eight calibration steps. During calibration you verify information specific to the
generator, adjust the date, and adjust the clock. You also adjust the REM circuit and
several values, or factors, that ensure the proper operation of the generator.
The calibration steps and the values you can adjust are summarized below. Certain values
are not adjustable but must be verified.
Notice
After completing any calibration step, proceed to the next step to save the values from the
completed calibration step.

Preparing for Calibration
Equipment required
• Bipolar footswitch and monopolar footswitch
• Two small test cables (less than 24" [61 cm] long) with banana plugs
• REM plug (modified)
• Resistor substitution box
• Oscilloscope
• True RMS voltmeter (such as the Fluke 8920A or equivalent)
• Current transformer (such as the Pearson Model 411 or equivalent)
• Noninductive power resistors (such as a Dale NH-250) with these values (in􀀺): 10,
20, 30, 100, 200, 500, 1000, 1500, 1800, 2000, 2200, and 3000
If these exact values are not available, you may substitute series or parallel
combinations of other values.
Entering Calibration Mode
When you are in calibration mode, the calibration step number appears in the Bipolar
display. The value(s) associated with each calibration step appears in the Cut and Coag
displays. You use the Cut and Coag up (􀀧) or down (􀂒) arrow buttons to adjust the
displayed values.
1. If the generator is off, turn it on.
If you removed and/or replaced the battery, alarm number 212 will appear in the Cut
display the first time you turn on the generator. Turn off, then turn on the generator
to clear the number. Then calibrate the generator.
If any other number appears, calibrate the generator before taking the appropriate
action to respond to the number.
2. To enter calibration mode, simultaneously press the Recall, Pure, and Low (Desiccate)
buttons.
The first calibration step number (C1) appears in the Bipolar display. For instructions
on completing this step, refer to the first calibration step, Verifying the Generator
Data on page 5-28.
If an error occurs during calibration, an alarm number will appear in the Cut display. Note
the number and refer to Chapter 6, Troubleshooting.
Notice
After completing any calibration step, proceed to the next step to save the values from the
completed calibration step.

Exiting Calibration Mode
You can exit calibration mode at any time. If you want to save the new values for a
particular calibration step, press the Bipolar up arrow (􀀧) button at the end of that step
before exiting calibration mode. Calibration values are saved one step at a time.
For example, if you only want to adjust the clock, first enter calibration mode and press
the Bipolar up arrow (􀀧) button until the generator displays calibration step 3 (C3). Next,
change the hour and/or minute values. Then press the Bipolar up arrow (􀀧) button. This
saves the changes for calibration step 3 (C3) and displays the next calibration step (C4).
After saving the changes, turn off the generator to exit calibration mode.
If you do not want to save the changes you make for a particular calibration step, turn off
the generator [do not press the Bipolar up arrow (􀀧) button at the end of the step]. The
values that were in effect before you started that step remain in effect.
To save the changes for the present calibration step, press the bipolar up arrow (􀀧) button
to display the next calibration step number. Then, turn off the generator to exit
calibration mode.
or
To exit calibration mode without saving the changes for the present calibration step, turn
off the generator.
Verifying the Generator Data
In calibration step 1 (C1), you verify the generator model number and the software
version numbers for the main and feedback microcontrollers. You cannot adjust these
values:
• The generator code (model number) for the Force FX Electrosurgical Generator C
generator is 4.
• The software version number for the main microcontroller may vary among
manufacturing lots, but should never be 0.
• The software version number for the feedback microcontroller may vary among
manufacturing lots, but should never be 0.
If one or more of the values that appear as you complete this calibration step are not
correct, call the Covidien Service Center.
1. In the Bipolar display, verify that the calibration step number is C1.
2. In the Cut display, verify that the generator model number is 4.
3. In the Coag display, verify that the main microcontroller version number is a value
other than 0.

4. To display the feedback microcontroller version number, press the Med (Fulgurate)
button. Verify that the version number in the Coag display is a value other than 0.
5. To proceed to the next calibration step, press the Bipolar up arrow (􀀧) button.
At the end of each calibration step, press the Bipolar up arrow (􀀧) button to advance
to the next step. If you need to return to a previous calibration step, press the Bipolar
down arrow (􀂒) button.
The Bipolar up arrow (􀀧) button cycles through the calibration steps. For example,
when you reach step C10 and press the Bipolar up arrow (􀀧) button, the generator
returns to step C1.
