4.3 The System Function
The subfuctions of the System function are described below. Specific
procedures for their use follow the descriptions:
• Auto-Cal: Used to define an automatic calibration sequence
and/or start an Auto-Cal.
• PSWD: Security can be established by choosing a 5 digit
password (PSWD) from the standard ASCII character set. (See
Installing or Changing a Password, below, for a table of ASCII
characters available.) Once a unique password is assigned and
activated, the operator MUST enter the UNIQUE password to
gain access to set-up functions which alter the instrument's
operation, such as setting the instrument span or zero setting,
adjusting the alarm setpoints, or defining analysis ranges.
