4.12 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-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.
4.13 Disabling The Calibration Password
Normally, operators are required to enter the calibration password when doing a manual
calibration via the ZERO or O3GN buttons. To allow calibration without entering the password,
press SETUP-PASS and set it to OFF, and then press ENTR to accept the change, or EXIT to
leave it unchanged. To require the calibration password, set the variable to ON.
4.14 Setting The Fault LED Timeout
The Model 401 can be set up so that the red fault LED on the front panel turns off automatically
if no warning conditions persist. Any warning messages will still be displayed, however. To set
the fault LED timeout, press SETUP-MISC-MORE-FILT and enter a value of from 0 to 300
seconds. A value of 0 disables the timeout, meaning that the fault will continue to blink as long
as a warning message is displayed. For example, to cause the fault LED to turn off if no warning
conditions have occurred for at least 5 minutes, set the variable to 300 sec.
NOTE
It is not advisable to set the timeout to an extremely short value such
as 1 second. Doing this may make the fault LED behave strangely.
This is because if a warning condition persists and the fault LED
timeout is very short, then the warning condition will be trying to
turn it off. The result will be an irregular blinking of the fault LED.
You should set the timeout to a value of at least 15 seconds.
