Figure 3-1 shows the hierarchy of functions available to the operator via the functionbuttons.Thesixfunctionsofthebuttonsontheanalyzerare:
•Analyze. This is the normal operating mode. The analyzer monitors the concentration of the sample, displays the percent or parts-per- millionoftargetfluidorcontamination,andwarnsofanyalarm conditions.
•System.Thesystemfunctionconsistsofninesubfunctions.
Four of these are for ordinary setup and operation:
•Setup an Auto-Cal
•AssignPasswords
•Log out to secure system
•InitiateaSelf-Test

Twooftheseareforprogramming/reprogrammingtheanalyzer:
•Definefluidapplicationsandranges(Refertoprogramming section, or contact factory.)
•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 three analysis ranges that can be switched automatically with autoranging or used as individual fixed ranges.
Any function can be selected at any time by pressing the appropriate button (unless password restrictions apply). The order as presented in this manual is appropriate for an initial setup.
