8.11.1 BAUD Rate

The BAUDrate is the first parameter in the menu. The BAUD rate setting de-

termines the serial communications transmission rate.

The BAUDrate parameter is indicated by,

bAUd Serial BAUD rate parameter

Press “SET” to choose to set the BAUDrate. The current BAUD rate value is

then be displayed.

2400 b Current BAUD rate

The BAUDrate of the serial communications may be programmed to 300 600,

1200, 2400, 4800, or 9600 BAUD.2400 BAUD is the default setting. Use “UP”

or “DOWN”to change the BAUD rate value.

4800 b New BAUD rate

Press “SET” to set the BAUDrate to the new value or “EXIT” to abort the op-

eration and skip to the next parameter in the menu.

8.11.2 Sample Period

The samplep eriod is thenext parameter in the serial interface parameter menu.

The sample period is thetime 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 overthe serial interface

approximatelyevery five seconds. The automatic sampling is disabled with a

sampleperiod of 0. The sample period is indicatedby,

SPEr Serial sample period parameter

Press “SET” to choose to set thesample period. The current sample period

valueis disp layed.

SP=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.

SP=60 New sample period

8.11.3 Duplex Mode

The nextparameter is the duplex mode. The duplex mode may be set to full du-

plexor half duplex. With full duplex any commands received by the calibrator
