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 measure-
ments transmitted from the serial interface. If the sample rate is set to five, the
bath transmits the current measurement over the serial interface approximately
every five seconds. The automatic sampling is disabled with a sample period of
0. The sample period is indicated by,
SAnPLE
Serial sample period parameter
Press “SET” to choose to set the sample period. The current sample period
value is displayed.
SA= 1
Current sample period (seconds)
Adjust the value with “UP” or “DOWN” and then use “SET” to set the sample
rate to the displayed value.
SA= 60
New sample period
9.14.3
Duplex Mode
The next parameter is the duplex mode. The duplex mode may be set to full du-
plex or half duplex. With full duplex any commands received by the bath via
the serial interface are immediately echoed or transmitted back to the device of
origin and the command is executed. With half duplex the commands are exe-
cuted but not echoed. The duplex mode parameter is indicated by,
dUPL
Serial duplex mode parameter
Press “SET” to access the mode setting.
dUP=FULL
Current duplex mode setting
The mode may be changed using “UP” or “DOWN” and pressing “SET”.
dUP=HALF
New duplex mode setting
9.14.4
Linefeed
The final parameter in the serial interface menu is the linefeed mode. This pa-
rameter enables (on) or disables (off) transmission of a linefeed character (LF,
ASCII 10) after transmission of any carriage-return. The linefeed parameter is
indicated by,
LF
