Teledyne 300 Setting the RS-232baud rate, Setting the analyzer I.D, Data acquisition system DAS

NEXT until D/A CALIBRATION is displayed and press ENTR. Press CFG to enter the D/A configuration menu. Use the NEXT and PREV buttons to select the desired analog output and press SET. Enter a value of from -500 mV to +500 mV (other ranges will ratio accordingly), followed by ENTR to accept the change, or EXIT to leave it unchanged. The offset will be reflected immediately on the strip chart recorder or other instrument.

4.8 Setting the RS-232 baud rate

To set the baud rate for the RS-232 channel, press SETUP-MORE-COMM-BAUD. Press 300, 1200, 2400, 4800, 9600, or 19.2 followed by ENTR to accept the new baud rate, or EXIT to leave the baud rate unchanged.

4.9 Setting the analyzer I.D.

Each Analyzer may be programmed with a unique I.D. number which appears on all RS- 232 messages. To set the Analyzer I.D., press SETUP-MORE-COMM-ID. Enter a 4- digit number from 0000 to 9999, followed by ENTR to accept the new I.D., or EXIT to leave the I.D. unchanged. If changed, the new I.D. number will appear on all RS-232 reports from this Analyzer.

4.10 Disabling the calibration password

Normally, operators are required to enter the calibration password when doing a manual calibration via the CALZ, CALS, or CAL buttons. To allow calibration without entering the password, press SETUP-PASSand set it to OFF, and then press ENTR to accept the change, or EXIT to leave it unchanged. To enable the calibration password, set the variable to ON.

4.11 Data acquisition system (DAS)

The Model 300 contains a flexible and powerful built in data acquisition system (DAS) that enables the analyzer to store concentration data as well as many diagnostic parameters in its battery backed memory. This information can be viewed from the front panel or printed out through the RS-232 port. The diagnostic data can be used for performing “Predictive Diagnostics” and trending to determine when maintenance and servicing will be required.

The logged parameters are stored in what are called “Data Channels.” Each Data Channel can store multiple data parameters. The Data Channels can be programmed and customized from the front panel. A set of default Data Channels has been included in the Model 300 software. These are described Section 4.11.1. For more information on programming custom Data Channels, a supplementary document containing this information can be requested from Teledyne API.
