ture. The factory default and maximum are set to 650°C. For safety, a user can
adjust the HL down so the maximum temperature set-point is restricted.
HL
High Limit parameter
Press “SET” to enable adjustment of HL
H=650
Current HL setting
Adjust the HL parameter using “UP” or “DOWN”.
H=400
New HL setting

7.11 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.
7.11.1 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 will
then be displayed.
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.
