3 Operation Model 6020
3-4 Part I
Teledyne Analytical Instruments
• Use the Curve Algorithm to linearize output. (Refer to
programming section, or contact factory.)
• Zero . Used to set up a zero calibration.
• Span. Used to set up a span calibration.
• Alarms. Used to set the alarm setpoints and determine whether
each alarm will be active or defeated, HI or LO acting, latching,
and/or fail-safe.
• Range. Used to set up four analysis ranges that can be switched
automatically with autoranging or used as individual fixed
ranges.
Any function can be selected at any time in the analyze mode (unless
password restrictions apply). The order as presented in this manual is
appropriate for an initial setup.
Each of these functions is described in greater detail in the following proce-
dures. The VFD screen text that accompanies each operation is reproduced, at
the appropriate point in the procedure, in a
type style.
3.3 The System Function
The subfunctions of the System function are described below. Specific
procedures for their use follow the descriptions:
• Dig_Filt : Adjust how much digital filtering should be on the
signal
• SELF-TEST : Performs a self-diagnostic test to check the integrity
of the power supplies, outputs, detector signal and preamplifier.
• PWD : Login security system for accessing to the setup functions.
• LOGOUT : Prevents an unauthorized tampering with analyzer
settings.
• AUTOCAL : Set the automatic calibrated timer schedule for Zero
and Span cycling.
• FILSOL : Select Span/Zero flag (filter) or Span/Zero solenoid
valve for calibration method.
• TRACK : Set the system reading to be held or followed by the
concentration “gas or filter” during calibration.
• CAL-HOLD-TIMER : Set the timing for calibration holding and
timing for the sample reading after return to analyze mode.
• ALGORITHM : Linearize the output for nonlinear characteristic.
