4.1 Introduction
Once the analyzer has been installed, it can be configured for your
application. To do this you will:
Set system parameters:
Establish a security password, if desired, requiring
Operator to log in.
Establish and start an automatic calibration cycle, if
desired.
Calibrate the instrument.
Define the three user selectable analysis ranges. Then choose
autoranging or select a fixed range of analysis, as required.
Set alarm setpoints, and modes of alarm operation (latching,
failsafe, etc).
Before you configure your 3000TA these default values are in
effect:
Ranges: LO = 100 ppm, MED = 1000 ppm, HI = 10,000 ppm.
Auto Ranging: ON
Alarm Relays: Defeated, 1000 ppm, HI, Not failsafe, Not
latching.
Zero: Auto, every 0 days at 0 hours.
Span: Auto, at 000008.00 ppm, every 0 days at 0 hours.
If you choose not to use password protection, the default password
is automatically displayed on the password screen when you start up,
and you simply press Enter for access to all functions of the analyzer.
