Stir Speed
The Stir Speed parameter adjusts stirrer motor speed. The factory default is 20.
Str SP Flashes Str Sp and then displays the setting
0 Current stir speed setting
To change the stir speed, push UP or DOWN.
16 New stir speed setting
Push SET to accept the new stir speed.
The stir motor speed must be varied for best stability. Table 3 shows nominal settings for several fluids.
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 which determine the operation of the serial
interface. These controls only apply to instruments fitted with the serial interface. The parameters in the
menu are: BAUD rate, sample period, duplex mode, and linefeed. Push UP to enter the menu.
BAUD Rate
The BAUD rate is the first parameter in the menu. The BAUD rate setting determines the serial
communications transmission rate.
The BAUD rate parameter is indicated by,
bAUd Flashes bAUd and then displays the setting
2400 b Current BAUD rate
The BAUD rate of serial communications is programmable to 300 BAUD, 600 BAUD, 1200 BAUD,
2400 BAUD, 4800 BAUD, or 9600 BAUD. Use UP or DOWN to change the BAUD rate value.
4800 b New BAUD rate
Push SET to set the BAUD rate to the new value or EXIT to abort the operation and skip to the next
parameter in the menu.
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 5 seconds. The automatic sampling is disabled with a sample period of 0. The
sample period is indicated by,
SPer Flashes SPEr and then displays the setting
SP= 1 Current sample period (seconds)
Adjust the value with UP or DOWN and then use SET to store the sample rate to the displayed value.
EXIT does not store the new value.
SP= 60 New sample period
