How to configure Channel or switch in Agilent data logger 34970A?

[AnkitRamani]

Hello,

I am dealing with Agilent Data logger in order to supply voltage to my device and for switching purpose.

I tried my self alot but i didnt found any solution will you please help me that how can i configure the voltage on perticular channel.

foe example in attachment i have attach one diagram and currently i am doing that task that i have to give 12v to Channel 4 of datalogger  34903A and from that i have to make one connection between 34903A and channel 6 of 34901A and from channel 6 i have to give connection to the device which I am using.

will you please tell me that how can i do so?

i have no idea about any thing of Data logger.

what should i have to do first?

Thank you very much.

I'll assume you have the 34970A instrument up and running with USB or GPIB and can see it under Measurement & Automation.

Download the ni device driver from aglient 34970A, download the programmers reference here

Download the zip file under 34970A/34972A Programmer's Reference Help

Open the file that says: 34970A-34972A_Command_Reference.chm this is the help manual.  Open the LabVIEW library hp34970a.llb and have a look at the examples.

Past here you need to select your device in the VISA drop down, configure and choose a channel..Usually in the hundreds 101, 102, 103, etc... or 200, 300 depending on which slot your card is in.

Your schematic makes no sense if you are trying to connect the +12 volts to your device. Connecting the 34901 does not do anything. Have you looked at the schematics of the switches? Why do you not connect the com pin of the 34903 directly to the device?

Thank you very much for reply,

Here I am attach my full schematic diagram and as well my GPIB setting Screen shots.

And will you please tell me that if suppose I want to set 10 volt on channel 103 and 108 then I have to use following command??

CONF:VOLT:AC 10,(@103,108)

from NI-Max.

please don't be angry on my silly questions because I have no idea and this is my last task to perform as an intern.

and will you please tell me that how can I connect my device to data logger directly for example in previous post Dennis told to give 12v directly form 34903A to device no need to use 34901A.

and How can I supply 12v to 34903A means I have to assign channel which carry 12v to 34903A???

I am using Modbus Library in order to communicate with my device.

Thank you very much.

No, the CONF:VOLT:AC 10,(@103,108) command does not even come close to setting 10 volts on the channels. The command says to setup to MEASURE ac volts on the 10 volt range. Please read the manual.

Do you understand how a relay works? Your original drawing shows a +12V connection to the NO (normally open) point of the relay. The COM (common) point will have that +12V present whenever you close the relay. If the point is to connect that +12V to your device, then you simply connect the COM to the device. I can't explain it any simpler than that.

The connections of the 34901 go to the internal DMM. If you leave that connection, you would be connecting the device to the negative input of the DMM and the +12V to the positive input of the DMM. This should all be clear by looking at the schematics of the 34901.

So, what is not clear at all is what you are actually attempting to do - apply +12 to the device or measure something.

AnkitRamani,

Just to make you feel better the first time I used the 34970A I was confused and still don't understand all the wonderful features it's capable of.

Looks like you are multilingual from one of the corrections...German?

Look on the back of the 34970A and you will see 100/200/300.  I'll assume that the 34901A is in slot 100 and 34903A is in slot 200, 34907A is in slot 300.  The channels for programming slot 100 (34901A) CH1, CH2, etc. are 101, 102, etc.  For slot 200 (34903A) CH1, CH2, CH3 etc. are 201, 202, 203...  For slot 300 (34907A) you are going to have to read the manual since I have not used this card.

You are also on your own with modbus since I'm not familiar with it.  But if you are able to use the text commands you should be able to follow one of the examples that Agilent has provided in my links above.

Don't feel bad about not being able to read relay ladder logic or not knowing how a relay works, it is rarely taught in school anymore but used heavily in test and automation.

As Dennis pointed out if you are trying to measure current on the +12V you need to move that signal to the higher channel on the 34901A not on CH6 as you have it....CH22 maybe.  Unless you are trying to measure a short?

I would recommend doing every command manually first and look at the measurements displayed on the 34970A and convince yourself that they make sense.  Go back to your first schematic and start simple and build on what you know already to complete the larger picture.

Regards,

´Thank you very much for helping ..

but unfortunately we have chrisrmas vacation so I am not allowed to go to the workshop so may be after vacation I will try again..

But I would again like to take this opportunities to say thank you very much for your guidance.

Have a delightful Christmas to all of you...

Hello Happy new year to all,

I have read all the command and related stuff  but the thing is its good to be more familiar with Agilent data logger but still I don't know how to use particular channel or switch in VI.

And as Dennis told to move 12v to higher channel instead of channel 6,but the thing is all the channels are assigned to different function and only channel 6 is free so   

will you please tell me that is this make any difference and from where can I connect 12v to channel 03 of 34903A ? Means what step should I follow..I am very confuse about that ..And how to configure Switch which I am using means is there any setting I have to do before using any channel or switch in data logger or can I assign it directly..??

Thank you very much ...

Hi all!!

           I'm using Agilent DSO-X 2002A oscilloscope. I have communicated the oscilloscope through LABVIEW2011. Now I'm getting problem in configuring two wave forms simultaneously by time delay. How to start acquiring data simultaneously..

Expecting the reply soon...

Don't hijack a completely unrelated thread and don't duplicate the same question in multiple threads. It is very inconsiderate.
