3.3 The System Function
The subfuctions 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.
•
APPLICATION: Used to define the analysis ranges and application
(gas used).
•
MODEL: Displays model number and software version.
•
OUTPUT: 4-20 MA: Adjust 4 and 20 mA output.
3.3.1 Setting up an AUTO-CAL
When proper automatic valving is connected, the Analyzer can cycle itself
through a sequence of steps that automatically zero and span the instrument.
Note: Before setting up an AUTO-CAL, be sure you understand the
Zero and Span functions as described in section 4.4, and
follow the precautions given there.
