the “EXIT” button while pressing the “SET” button and release to enter the
secondary menu. Press the “SET” button repeatedly until the display reads
“ProbE”. This is the menu selection. Press the “UP” button repeatedly until
the serial interface menu is indicated with “SErIAL”. Finally press the “SET”
button to enter the serial parameter menu. The serial interface parameter
menu contains the BAUD rate, the sample rate, the duplex mode, and the
linefeed parameter.
8.1.2.1 Baud Rate
The baud rate is the first parameter in the menu. The display prompts with
the baud rate parameter by showing “bAUd”. Press the “SET” button to
choose to set the baud rate. The current baud rate value is displayed. The
baud rate of the instrument may be programmed to 300, 600, 1200, or 2400
baud. The baud rate is pre-programmed to 2400 baud. Use “UP” or “DOWN”
to change the baud rate value. Press the “SET” button to set the baud to the
new value or the “EXIT” button to abort the operation and skip to the next
parameter in the menu.
8.1.2.2 Sample Period
The sample period is the next parameter in the menu and prompted with
“SAMPLE”. The sample period is the time period, in seconds, between tem-
perature measurements transmitted from the serial interface. If the sample
rate is set to 5, the instrument transmits the current measurement over the
serial interface approximately every five seconds. The automatic sampling is
disabledwithasampleperiodof0.Pressthe“SET”buttontochoosetoset
the sample period. Adjust the period with the “UP” or “DOWN” button and
then use the “SET” to set the sample rate to the displayed value.
8.1.2.3 Duplex Mode
The next parameter is the duplex mode indicated with “dUPL”. The duplex
mode may be set to half duplex (“HALF”) or full duplex (“FULL”). With full
duplex any commands received by the instrument via the serial interface
are immediately echoed or transmitted back to the device of origin. With
half duplex the commands are executed but not echoed. The default setting
is full duplex. The mode may be changed using “UP” or “DOWN” and press
-
ing “SET”.
8.1.2.4 Linefeed
The final parameter in the serial interface menu is the linefeed mode. This
parameter enables (“On”) or disables (“OFF”) transmission of a linefeed
character (LF, ASCII 10) after transmission of any carriage-return. The de
-
fault setting is with linefeed on. The mode may be changed using “UP” or
“DOWN” and pressing “SET”.
