ConMed ExcaliburPLUS PC - CAL Mode Entry Procedure; Navigating CAL Mode Menu; Entering Modes within CAL Mode; Understanding Calibration Status

때때 ㄴㄴ
NOTE: CAL Mode should not be used to per-
form routine calibration checks. Those tests are
better conducted in RUN Mode per Section 4.5.
If the unit proves to be out of calibration, the
possibility of a component failure should be elim-
inated as the cause before recalibrating. Once the
physical condition of the unit as been confirmed,
then CAL Mode may be entered to correct the
calibration.
4.6.1 CAL Mode Entry
CAUTION: Do not enter CAL Mode with-
out first reading and understanding the fol-
lowing material and ensuring that the neces-
sary equipment is on hand and accurate.
Improper calibration procedures can cause an
otherwise serviceable unit to become unusable
until calibration is corrected.
The CAL Mode is entered by powering up while
pressing the internal CAL switch, A3S1. If the
key is held for more than 30 seconds, the unit
will display an “Err 13.0” fault code.
Upon successful entry to CAL mode, a display
check occurs for 30 seconds or until any key is
pressed, and then “SLF dIA” is displayed in the
Cut and Coag power windows. The Bipolar
power display window shows the last two digits
of the Software part number, and the Program
window indicates the software revision level.
After the self diagnostics are run, the unit will dis-
play “C-C, 300, A”. At this time the CAL mode
entry is complete and calibration or diagnostics
can begin.
4.6.2 CAL Mode Menu
After entry to CAL Mode, the CUT power win-
dow will display “C-C”, which is one of five avail-
able mode selections. Any of the other modes
may be selected sequentially by pressing the CUT
Power Increase or Decrease keys. In some of the
modes, the other displays will display an option
applicable to that mode; these options are similar-
ly selectable by pressing the Increase or Decrease
keys next to the display. Activating an inappro-
priate key or control will result in a pulsating Key
Error tone. Details of how to use each mode
appear in following sections. The available CAL
modes, options and their uses are summarized in
Table 4.6.

4.6.2.1 Entering a Mode and Returning to the
Menu
When the desired Mode and Option are dis-
played, that mode is entered by pressing the
“STORE” key. Operation in each of the modes is
described in detail in following Sections.
In each of the three Calibration modes there are a
number of calibration points, which may be
selected, checked and adjusted. When work in a
mode is completed satisfactorily, pressing the
“STORE?” key will save all calibration changes
along with an updated CRC to the NOVRAM
and will return to the menu. If the calibration is
incomplete or nonmonotonic, an error code will
be displayed. Pressing the “STORE” key again
will restore the menu, from which the mode may
be reentered.
The Diagnostics modes are removed from the
menu after RF is activated in either of the Power
Calibration modes. It is not possible to return to
the menu from either of the Diagnostics modes
without turning power off and reentering CAL
mode.
4.6.2.2 Calibrated/Uncalibrated Status
If the menu MODE display for one of the three
Calibration modes is flashing, then one or more
points in that mode is uncalibrated. That mode
should be entered and calibration completed or
corrected.
Each point within a mode can be declared cali-
brated or uncalibrated by the microprocessor. An
uncalibrated point is flagged by a flashing display.
That point may be restored to a calibrated status
by recalibrating.
On initial entry to CAL Mode, the unit confirms
that the stored values haven't changed since the
last valid calibration. If there have been any
changes, all points are considered uncalibrated
and a complete calibration will be required to
make the unit functional. In this case, the unit
does load a set of nominal calibration values
which will bring a normal unit close to final cali-
brated values. The technician can use these values
by activating the unit for each calibration point,
but a real calibration should be done before
returning the unit to service.
