2400 b
Current baud rate
The baud rate of the serial communications may be programmed to 300, 600, 1200, 2400, 4800,
or 9600 baud. Use “UP” or “DOWN” to change the baud rate value.

the next parameter in the menu.
6.12.2 Sample Period
The sample period is the next parameter in the serial interface parameter menu. The sample
period is the time period in seconds between temperature 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 disabled
with a sample period of 0.

6.12.3 Duplex Mode
The next parameter is the duplex mode. The duplex mode may be set to full duplex or half du-
plex. With full duplex any commands are executed but not echoed. The duplex mode parameter
is indicated by,

6.12.4 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
