Operation

4.1Introduction

Although the Model 7300A is usually programmed to your application at the factory, it can be further configured at the operator level, or even, cautiously, reprogrammed. Depending on the specifics of the application, this might include all or a subset of the following procedures:

Setting system parameters:

Establish a security password, if desired, requiring Operator to log in.

Establish and start an automatic calibration cycle, if desired.

Routine Operation:

Calibrate the instrument.

Choose autoranging or select a fixed range of analysis.

Set alarm setpoints, and modes of alarm operation (latching, fail-safe, etc).

Program/Reprogram the analyzer:

Define new applications.

Linearize your ranges.

Special functions setup:

Set output reversal.

Set polarity reversal or offset output.S

Set gain amplification.

Before you configure your 7300A, the following default values are in effect: RANGE/APPLICATIONS: refer to data sheet on the first page of this manual;

Range: Manual

Alarm Relays: Defeated, 0.00%, HI, NOT Fail/Safe, not latching

 

Zero:

Auto, every 0 days 0 hours

 

Span:

Auto, at 10%, every 0 days, at 0 hours

 

Password: TAI
