TABLE 7.4

NOTE

THE COMMANDS IN TABLE 7.4 CAN ONLY

BE ENTERED VIA THE RS-232 PORT WHEN

THE ANALYZER IS IN THE SAMPLE MODE.

When a control command is issued, the CPU will respond by issuing a status report. For example if the host computer issues the command

"C CALZ<CRLF>"

to do a zero check, the CPU will send the status report

"C DDD:HH:MM IIII START ZERO CALIBRATION<CRLF>"

to the RS-232 output.

7.4 Diagnostics

The diagnostics mode can be entered from the RS-232 port as well as from the front panel. The diagnostics commands available are listed below.
