[F2 PL 4] 

Device locate: move to position 4 and reply when done.  (Device should be 

 

  

initialized prior to using this command for the first time.) 

......[F2 DL 4]  D

evice is now in position 4. 

[F2 DD 400] 

Set speed to 400 (acceptable range 100 – 900, with a default of 500). 

 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

13.  Reference Cuvette 

 

These commands will have an effect only for systems with two independently‐controlled sample 
holders. 

 
[R1 ...] 
 

To control and monitor the temperature and status of the reference cuvette using a Dual 
Temperature Controller, use any commands in classes 3‐8, 10 and 11, substituting 

R1

 for 

F1

.  There 

are no corresponding [R1 …] commands for command classes 1, 2, 9 and 12. 
 
If you wish to ramp the temperature of the reference and sample cuvettes together, please note the 
linking command, 

[F1 TL +]

, in command class 10. 

 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

15.  Control of Automatic Reports 

 

The TC 1 can be controlled manually using the buttons and the display on the front.  When a 
computer program is in use, the TC 1 will automatically send reports to the program whenever a 
manual change has been made.  The commands in this section are intended to allow the program 
to prevent the TC 1 from sending those automatic reports.

 

 

[F1 XX R(+/-)] 

Stop (R‐) or start (R+) reporting all manual changes, including those 

starting with [R1 and [F2. 

 

 

 

By replacing the XX with individual command codes, a program can 

selectively stop or start reporting of manual changes. 

 

[F1 SS R-] 

Stop reporting manual changes for the sample stirrer. 

[F1 TC R-] 

Stop reporting manual changes for the sample temperature control. 

[F1 TT R-] 

Stop reporting manual changes for the sample target temperature. 

[F1 PR R-] 

Stop reporting manual changes for the external probe connection. 

[F1 RR R-] 

Stop reporting manual changes for the sample ramp rate. 

 

[F2 PL R-] 

Stop reporting manual changes for the sample position. 

 
[R1 SS R-] 

Stop reporting manual changes for the reference stirrer. 

[R1 TC R-] 

Stop reporting manual changes for the reference temperature control.
