6.12.4
Soak Stability
The soak stability controls the required stability of the well temperature for the
soak time (see Section 6.5.3). The stability is in degrees Celsius. The default is
0.1°C. This value can be changed in the parameter menu.

Serial Interface Parameters
The serial RS-232 interface parameters menu is indicated by,
SErIAL
Serial RS-232 interface parameters menu
The serial interface parameters menu contains parameters that determine the
operation of the serial interface. The parameters in the menu are —BAUD rate,
sample period, duplex mode, and linefeed.
6.13.1
Baud Rate
The baud rate is the first parameter in the menu. The baud rate setting deter-
mines the serial communications transmission rate.
The baud rate parameter is indicated by,
bAUd
Serial baud rate parameter
Press “SET” to choose to set the baud rate. The current baud rate value is
displayed.
1200 b
Current baud rate
The baud rate of the serial communications may be programmed to 300, 600,
1200, or 2400 baud. Use “UP” or “DOWN” to change the baud rate value.
2400 b
New baud rate
Press “SET” to set the baud rate to the new value or “EXIT” to abort the opera-
tion and skip to the next parameter in the menu.
6.13.2
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 measure-
ments transmitted from the serial interface. If the sample rate is set to 5, the in-
strument 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,
