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 cal ib ra tion mo de , simulta ne ou sl y 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.
