TTI-7 Iss.02 – 06/11 

Input Buffer 

 

The instrument receives messages into an input buffer and only starts executing commands after receipt of a message 

terminator. The buffer can store up to 100 characters including separators and terminator. 

 

Sending a new command before the existing command is executed may cause unreliable operation. It is advisable to 

query the Status Byte (*STB) to check on the current status of the instrument before sending a new command. 

 

Sending  a  command  whilst  the  instrument  is  transmitting  (following  a  ?  command)  may  result  in  the  transmitted 

response being corrupted. It is advisable to wait for the expected response to be transmitted before sending a new 

command. 

 

Measurement Configuration Commands 

 

CONFigure Group 

These  commands  allow  the  measurement  configuration  of  each  channel  to  be  set  up,  but  they  do  not  trigger  a 

measurement. If the instrument is in the trigger-run mode it will change to the trigger-hold mode, or if in the trigger-

single mode, it will remain in the trigger-single mode. 

 

CONFigure:CHANnel <

channel

> 

Selects the channel to be measured (use CONF:TEMP to configure the measurement parameters). Only available 

channels should be selected, else the command will be ignored. 

 

Terminates the current measurement cycle and scanning routine. 
Sets the scanner and data logger modes to OFF. 

 

<

CONFigure:TEMPerature:TC <type>,<rj mode>,<ext rj standard> 

Sets the selected channel for a thermocouple measurement according to the following parameters.

(EN60751) 

 

 

 

4-23   

(User Probe 1-20) 

 

Terminates the current measurement cycle and scanning routine. 

Sets the scanner and data logger modes to OFF. 

 

Note:   When <

rj mode

> is set to Off or Int, the <

ext rj standard

> parameter must be set to 0, otherwise the 

command is not recognised.
