EXECUTION Immediate
SYNTAX
E
Terminate Calibration Mode
DESCRIPTION
Note: This command is only for advanced users who perform their own calibration. It is not necessary for
normal, everyday operation.
To use this command the unit must be in Calibration Mode. The End Calibration Mode (
E
) command is then
used to take the unit out of Calibration Mode. Once this command has been executed the unit will no longer be
in Calibration Mode and the Enter Calibration Mode command (
K
) must be issued to re-enter Calibration Mode.
Chapter 6, Calibration contains additional information.
