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. This 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 .
For more information on manual calibration, see chapter System Calibration .
Note: This command is only valid when the calibration protection is disabled via the rear DIP microswitch 9.
