Special operation, workshop level only!
Control Unit RE-Calibration
Note
: This operation requires
two
Calibration Adapters (part
No. OP3-099),
and the special service SW-version 1.3S (
or
newer).
Connect a calibration adapter (part No: OP3-099) to the
control unit and press on/off. The unit will automatically enter
Calibration Check mode.
After the unit has returned steady and reliable values (after 2-
5 min), indicated by the red or green markings of each of the
readings, the unit can be unlocked by pressing the key
sequence “left arrow”, “down arrow”, “right arrow” and “up
arrow”.
The system will display a “U” after the reference resistance
indicating that a calibration update process has been initiated.
Let the system measure for approximately 10 - 15 minutes and
the system will then automatically prompt for the second
calibration adapter to be inserted
(
note:
two separate adapters are mandatory for a control unit
re-calibration).
Approximately 5 minutes after the second adapter has been
fitted the verification process is finished, and the system
returns steady values (indicated by the red or green markings
of each of the readings), the readings (the calculated
resistance for each channel) should correspond to the adapters
reference resistance within 0,025 ohm.
“Enter” writes the new calibration values to the CU
,
MENU exits without changing the values.
WARNING:
This procedure may only be performed by Kanmed factory or by a Kanmed certified
workshop! CU re-calibration should NEVER be performed in field. Furthermore, the cu unit must be
in thermal balance before the procedure is performed, i.e. it should be in operating temperature.
The calibration adapters must also be room tempered (approx 21 deg C).
Failing in this procedure will/might jeopardize the operation of the system and can in worst case
result in the overheating of a patient.
