Hi Kurt, how you've been? May i ask you for your mail so i can ask you directly some of my new questions about the temp. controller? If you can´t give it or don't want too, i understand and i will post here asap.

Hi again Kurt, I've been away from the project for little while, and now i'm back. And i need some help again, if you can of course. I've tested the last attach you posted here, and it seems to work very good, except the fact that the ramp looked more like a step. I think the temp. controller isn't assuming its rate and its skiping from setpoints as quick as it can. Other question i have is about how to do the step mode on this controller? Is it by a similar process to this 1 that you've done? For last, i'm having trouble configuring the VI Package Manager, since it is not communicating with the labview, it opens the labview but it always says time exceded. I have formated the laptop, and i'm doing it like i did the 1st time and it worked. Thanks in advance for your help.

Thanks very much Kurt Friday. Very nice reply, i have never worked with this, but i will try to adapt it to my situation and see if it works. Still, there's something that i wanted to ask you before, it will run that script but what if i want the user to fill those values? Because i have already done, 1 VI full with validations for the parameters introduced by the user. Hope you understand me and that you keep in touch. Thanks once more for your wonderful support. =)

Thanks MZU for your reply, i forgot to click watch this topic, and i thought i did not have any reply. Can you please take a look at my other Post, it's the evolution of this VI, so you might be able to help me with it. Regards, THN

Thanks for your reply Kurtis, But tell me, should it be something like this? What should i wire in the rate value of the Ramp Status.vi ? Because in my VI, i want the Ramp to start from a user defined Minimum and not from the Ramp default minimum. Still, how should i do it, if i want to add more ramps? How do i give temperature limits to it? Making it run from for ex. 10K to 20K, and in the end i make a delay and only after start another 1 from 30K to 40K. Please help me out with this, i'm getting out of time with this..:S Thanks for your support. 1º teste CRT.vi

Hi guys, I'm using the LakeShore 325 Temperature Controller for some measures. And i got stucked with this problem: i need to divide the ramp by segments. Which means that the ramp will not start from 0 all time. My idea is to make 1 ramp divided at a maximum of 4 segments. For ex: 1st segment from 100K to 200K, 2nd ramp from 250K to 400K, etc.. The problem is that i can't find that option on the instrument driver. It only allows me to configure the ramp, which means, that i can insert it's rate and if i'm going to have a set point or not. And the other option that is on the instrument driver is the configuration of the setpoint, that only allows me to insert 1 setpoint. What should i do? I need 2 setpoints, 1 for the minimum temperature and 1 for max. temperature. I can't use the PID control, and i'm attaching the drivers here with 1 sketch of my main VI. Thanks in advance.

Hi guys, I need to read several data from 4 different instruments. I got 1 power source, 2 multimeters and 1 temperature controller. The powersource will give current to the circuit while the 2 multimeters will read voltage and current to measure the resistivity. The temperature controller will run as a ramp or step, and will take the temperature values. And i need to know if i'm doing it right like the attach i'm sending. I know that probably nobody has these specific drivers installed, but if anyone has already worked with this or similar, give me some ideas or tips, please. Any opinions are welcome. Thanks in advance. THN teste-série.vi
