3 Operational Procedure
Initialization and basic functionality checks of the calibration equipment are performed
when the calibration system is first booted. These checks insure that the calibration
equipment is working properly. In addition, part of the operational procedure should be a
step to calibrate the equipment each day, or as often as is necessary. Once everything
is verified, the operator is free to pick ‘calibrate handle’ from the menu. The description
that follows assumes the full calibration and functionality testing is enabled.
Establish Communications
After a serial number is entered, the operator is prompted to place the handle into the
base. When the operator indicates that the handle is in the base, the system will attempt
to establish communications with the handle. This step will verify that the handle is
properly seated in the base and that the handle is alive.
Note that a communications failure can occur at any point during calibration and testing.
If it does occur, the operator will be notified.
Errors: Corrections:
Cannot talk to handle. Unit not powered up, flex or micro problem
New or ReCal Prompt
A prompt appears to ask if this is a new handle that has never been calibrated, or a
handle in for recalibration. The difference is that new handles will have a full initializa-
tion of the PROM with default values being loaded. Recalibration will preserve impor-
tant usage count information kept in the PROM.
Get Handle Serial Number
If this is a new unit, a prompt will appear requesting the serial number. This serial
number is bar coded directly on the handle. The serial number can be typed in by hand
or scanned in.
Errors: Correction
Invalid serial number. Reenter serial number
