the appropriate point in the procedure, in a Monospaced type style. Push-button names are printed in Oblique type.

3.3The 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 “fluid 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 (fluid used).

•MODEL: Displays model number and software version.

•OUTPUT: 4-20 MA: Adjust 4 and 20 mA output.

•SHOW_NEG: Whether to display negative readings or not; affects analog output too. No negative readings is the default.

3.3.1Setting 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 instru- ment.
