DESCRIPTION
Note: This command is only for advanced users who perform their own calibration. It is not necessary for
normal, everyday operation.
The Change Calibration Keyword (
*K
) command allows the changing of the Calibration Keyword which is a user-
defined password. The password is a safety feature to prevent unauthorized personnel from entering calibration
mode and potentially altering calibration constants. The new keyword must be a 5-digit decimal number. Once
the keyword is set, it will, thereafter, be used by the Enter Calibration Mode (
K
) command to determine entry into
Calibration Mode.
Note: This command is only valid when calibration protection is disabled via the rear panel calibration protection
disable/enable DIP switch. Refer to Chapter 6 for detailed instructions on calibration .
