question about temperature controller

[yzhu]

Hey guys!

I am having trouble with collecting data from a temperature controller using its own driver. The model of the instrument is ILX Lightwave LDT-5910B. The problem is that I want to increase the temperature in a very small step , for example 0.01 deg C/ step or even 0.005 deg C/step. I want to set the step by some logic using labview because I can not find any setting from the manual of the temperature controller. Does anyone have some suggestion for how to do this?

Thanks!

Hai,

First justify if the controller has the capability to control temperature down to that resolution (0.001deg C).  I had a glance of that models manual and it was 0.2deg C.

It has a GPIB interface through which you can set the required parameters.  For GPIB communication you can use PCI-GPIB or USB-GPIB interfaces to control the instrument.

For basics on GPIB instrument control refer here:http://zone.ni.com/devzone/cda/tut/p/id/2761

I looked at the manual, the minimum step is 0.1 deg C, so I am not able to control this that prcise.

But I am happy with the answer!

Thank you!
