4. OPERATING INSTRUCTIONS
The T101 is a micro-computer-controlled analyzer with a dynamic menu interface for
easy and yet powerful and flexible operation. All major operations are controlled from
the front panel touch screen control.
To assist in navigating the system’s software, a series of menu trees can be found in
Appendix A of this manual.
NOTE
The ENTR button may disappear if you select a setting that is invalid or out of the allowable range for that
parameter, such as trying to set the 24-hour clock to 25:00:00. Once you adjust the setting to an
allowable value, the ENTR button will reappear.
4.1. OVERVIEW OF OPERATING MODES
The T101 software has a variety of operating modes. Most commonly, the analyzer will
be operating in
SAMPLE mode. In this mode, a continuous read-out of the H
2
S
concentration is displayed on the front panel and output as an analog voltage from rear
panel terminals, calibrations can be performed, and
TEST functions and WARNING
messages can be examined.
The second most important operating mode is SETUP mode. This mode is used for
performing certain configuration operations, such as for the DAS system, the reporting
ranges, or the serial (RS-232/RS-485/Ethernet) communication channels. The
SET UP
mode is also used for performing various diagnostic tests during troubleshooting.
The Mode field of the front panel display indicates to the user which operating mode the
unit is currently running.
In addition to SAMPLE and SETUP , other modes the analyzer can be operated in are:
