• Calibration SMU 4330 problem

  I tried to calibrate the SMU-4330 and getting coherent errors when you try to Gain accuracy test of the calibration Procedure 4330/4331 Express SC OR

  For the three brand new 4330 cards, I get an error in table 5 of the manual for the outputs of calibrator: 295,8, 341,3, and 358,8, as well as an error in table 4 for the outputs of calibrator: 341,3 and 358,8.

  I am fairly confident that I am following the procedures correctly. I was using the 5220 recommended A Fluke calibrator and the cards past all the other verification tests except the Test of accuracy of Gain.

  Anyone have any ideas? Arrays of textbooks has been updated?

  Thanks in advance

• wiring of remote sensing and shielding to the Earth, 9237 requirements

  Hi, I have a set of scales (full-bridge) connected to a 9237 (in a 9172 chassis), and I have two questions regarding the wiring:

  (1) requires remote sensing that you have two additional sons detach from the cell, to the place where the wires attach to the wheatstone bridge?

  (2) where I should connect the shield of the load cell 50/60 Hz noise? to the Ex-terminal (as well as the Ex-fil)?

  Thank you

  Claire.

  Hi Claire,

  (1) Yes.  Drivers of remote sense must be connected to the points where the voltage wires connect to the bridge circuit.

  (2) Yes.  The shielding must be connected to the reference of the unit, who is the EX - for the 9237.

  See NI 9237 Instructions and specifications manual and this DevZone for more information.

• BlackBerryContact returned from remote sensing

  Hello

  I hope someone can help me; is there a way to determine from the BlackBerryContact returned from remote research that the BlackBerryContact came from a distance search rather than a local search? A field in the contact?

  Thank you

  David

  No, there is no field that indicates if the contact came from a remote research or is stored locally on the BlackBerry smartphone.

• CTRL and down remote sensing

  Hello

  I want to put a public var to true when you press ctrl shift and set to false, then when they are not pressed.  This is to link with some features of datagrid that respond differntly when Ctrl or shift are down.

  onKeyBoardDown() is sussessfully followed when the keys are down, but onKeyboardUp is not when they are released. Why is this?  Thank you!

  stage.addEventListener (KeyboardEvent.KEY_UP, onKeyBoardUp);

  stage.addEventListener (KeyboardEvent.KEY_DOWN, onKeyBoardDown);

  private void onKeyBoardDown(event:KeyboardEvent):void

  {

  If (event.ctrlKey) //if control button is pressed

  {

  trace ("CTRL on ');

  }

  Else if (event.shiftKey)

  {

  trace ("SHIFT on ');

  }

  on the other

  {

  trace ('NONE!');

  }

  }

  private void onKeyBoardUp(event:KeyboardEvent):void

  {

  If (event.ctrlKey) //if control button is released

  {

  trace ('CTRL off');

  }

  Else if (event.shiftKey)

  {

  trace ("off SHIFT");

  }

  }

  To answer why your original code does not work, you use KeyboardEvent to indicate the current state of the 2 keys in a way ' if/else '.

  For example, when you release the CTRL key, event.ctrlKey will always be false (because it is more of course). Same thing with the release of TRAVEL if you release that will always make it false.

  Use the keycode as moccamaximum mentioned, but you have to detect combinations do not limit it to the "if/else".

  for example:

  var ctrlIsDown:Boolean = false;

  var shiftIsDown:Boolean = false;

  function onKeyBoardDown(e:KeyboardEvent):void

  {

  If (e.keyCode is 17)

  {

  trace ("CTRL on ');

  the value of state var for CTRL

  ctrlIsDown = true;

  }

  do not use on the other, separate logic

  If (e.keyCode is 16)

  {

  trace ("SHIFT on ');

  set var to SHIFT State

  shiftIsDown = true;

  }

  }

  function onKeyBoardUp(e:KeyboardEvent):void

  {

  If (e.keyCode is 17)

  {

  trace ('CTRL off');

  the value of state var for CTRL

  ctrlIsDown = false;

  }

  do not use on the other, separate logic

  If (e.keyCode is 16)

  {

  trace ("off SHIFT");

  set var to SHIFT State

  shiftIsDown = false;

  }

  make a function to check the key States

  If necessary here and making adjustments

  based on shift or control separately

  }

  keyCode has limits, beware. Alternative keyboards are known to change the values for keycode of unexpected results. Modify if needed. Consider charCode and keyCode has other limits:

  If it is not there in the pilot of the plane, I don't know, then you could certainly write a VI to activate Remote Sensing. The command should be in the manual.

• Confusion about the Source of excitement in the bridge SMU-4331 input module

  Hello

  I had some confusion through the input of the bridge SMU-4331 sheet module.

  In the features section of excitement, its current Minimum as 29mA says. What it means. It can only current greater than 29mA delivery!

  

  I think this should me Maximum current specification.

  If you look at the table below

  

  350 ohm resistance, the current should be 10V/350 ohm = 28.5mA

  but for 1 K ohm, current will me 10V/1Kohm = 10mA, which isn't normal, if you specify current minimum as 29mA.

  any thoughts?

  Kind regards

  Mirash

  Hello Mirash,

  I'm glad I could help!

  As for your other question, the SMU-4330/4331 are inherently peripheral ratiometric.  This means that they are designed to detect the level of excitement and range of the ADC to the appropriate scale.  In this way, we can compensate for permanent changes in the voltage.  One of our engineers wrote a big article really nice area on the subject I would recommend that you take a look at: Sensors of Measuring Bridge-Based with the ratiometric approach

  See you soon,.

• PXI chassis with remote hot-plug

  Hello

  I use the SMU-PCIe8371 with SMU-8370 remote control instruments in the SMU-1075 chassis in Vista. In order to see my instruments in MAX the chassis must be turned on when I reboot Windows. If I disable the chassis while Windows is running, I have to restart to be able to reuse the instruments.

  Is it possible to make MAX see the chassis if it was not executed when Windows started or has been disabled while Windows is running?

  Thank you!

  Hello

  You can disable and enable the bridge PCI to PCI in the Device Manager, but this is not recommended or supported. I also suggest that you turn off the chassis while Windows is running, which is essentially the same as the withdrawal of a card PCI of your computer while the PC is on. This can lead to problems with your system, such as the database of MAX, which isn't very fun to solve. The recommended method to start your system is always chassis first, followed by the PC, and to stop, is PC first, followed by the chassis.

• Blocking incoming MIDI orders

  I am aware that some MIDI messages (like aftertouch and maintain) can be filtered, but is it possible to block or filter the MIDI cc numbers (orders) all or part in MainStage 3? I am interested because I started doing concerts outside the city in which I present with my computer mac laptop and keyboards are rented. Unfortunately, many times theses keyboards are MIDI messages that screw my MainStage performance and there is not enough time to understand before showing. If I could program MainStage to ignore everything except what I really need (volume, expression, etc.) it would make life easier. Has anyone encountered this problem? I with my own personal keyboards as well, but I found them accordingly, that's why MainStage works very well when I play locally with my own material. Any help or ideas would be appreciated. Thank you

  I don't think that Mainstage can filter other streams of midi data that you already mentioned in the tabs in midi in patch mode.

  I often use Yamaha keyboards as controllers of the Motif series, for example, and they spit active remote sensing and midi sync. Although he's not trashing the way responds Mainstage, I have to manually disable sync midi on the controller itself and I can filter midi well active detection.

  I think it would be cool to have Mainstage, be able to do this

• Error-201427 on PXI-5122 since NI MAX system

  I need to check that the PXI-5122 is supported by NO-Scope 4.0.0 under WINdows 7 64-bit. If so, I guess I can get a damaged card. The system was running under the old computer / code / drivers last month.

  Scenario is this: I'm upgrading of already running code to a new computer and 32-bit 64-bit CVI CVI. After plowing, of code tweaks, PXI, 5122 digitizer shows through a new error in the code. I go back NI Max and I get this related error when I try to post.

  "The driver could not communicate with PXISlot2, generates the following message:

  Error-201427 to the autotest

  Possible reasons:

  The specified device is not supported in the API OR-DAQmx.

  Specified device PXISlot2.

  Seeing this, I have tried NOR updated, and nothing has been marked. I shut down the system and reseat the card. Then I checked the version of NOR-Scope (was 3.9.4) OR MAX I downloaded manually OR-Scope 4.0.0. Same mistake.

  The 5122 is in slot 2 and NI MAX identifies the card as "2: NOR-PXI-5122"PXISlot2"

• Place HP 34401 in Local with GPIB-USB-HS Mode

  Hello

  I'm using LabVIEW 2010 SP1 to control the 34401 HP with the NI GPIB-USB-HS device. I use I/O built-in 34401 instrument drivers.

  If I plugged in everything, the 34401 will be immediately placed in "Remote" mode when I run my software. However, I would like to be able to use LabVIEW to force the 34401 to 'Local' mode Unfortunately I could not find a way to do this. I tried Close.vi, but has no effect.

  Here are my planned operation if it makes things clearer:

  1. Launch the software
  
  
  2. Initialize the 34401
  
  
  3. Place the 34401 in the 4W resistance measurement mode
  
  
  4. Pass the 34401 in "local" mode so that the end user can adjust a knob until the desired resistance is obtained while seeing the value of the resistance to change on the 34401
  
  
  5. Re-initialize the 34401 when I need to switch to another measure

  If not, is there a way to get the 34401 to permanently display how it is taken in remote mode?

• amplification of the strain by using the cDAQ

  Hello

  I am a newbie in the use of DAQ hardware and hope someone can help out me.

  I recently bought a cDAQ with the NI 9237 to measure the strains. The strains that I try to measure are very small 1 series micro. A bit of research showed me that I need to amplify the signal to measure these small strains (correct me if I'm wrong). But I'm not able to find amplifiers for the cDAQ.So, the questions I have are-

  1. is it possible to measure these small strains (1 strain micro) using the cDAQ? If so, do I need an amplifier?

  2. If I need an amplifier, are there more specific for the cDAQ with the 9237? If this is not the case, how and where can I get one?

  Thank you

  SID

  SID,

  These results were very shocking for me also, so I looked into it further.  It seems that the 9237 can do better.   Assuming you're within 5 degrees of the calibration temperature (25 ° C), 9237. 05% of span of error and. 05% offset error.  With the range of configuration and 25mV/V full-bridge, you can calculate the absolute accuracy of the 9237 with the following formula.  (Sound of full-bridge = 0.9 microV/V)

  absolute accuracy = (gain error * reading) + (error offset * range) + (noise)

  Do the math, we get

  25mV/V + / 25.9 microV/V

  In a full-bridge configuration: V/Vex =-(Gauge Factor) * strain

  
  

  With a typical GF of ~ 2.0, we can say that the accuracy of the strain will be

  12.5 mm/m + / microm 12.95/m

  It's a little more in the range that you hoped for.  Sorry for the confusion.

  If this does not work for you, we sell solutions PXI who will be able to measure more precisely.  Similar math help and type of configuration of full-bridge with SMU 4330 plug, we get:

  12.5 mm/m + / 3.48 microm/m

  In my view, that it is card data acquisition based on a bridge more precise and accurate that we sell.  It requires a controller/chasis PXI.

  Please let me know if you have any other questions!

  Sincerely,

• cDAQ Module Question

  Hello

  I currently have the following equipment:

  cDAQ-9178

  OR-9401

  OR-9219

  I use the module OR 9401 to drive the output PWM signals is calculated by a PID controller in two controlled thermal systems.  I use the NOR-9219 module to measure temperature, such as remote sensing by thermistors.  These temperature values are used in my PID controller to calculate the error.

  I am now interested in measuring a number of other temperatures on my device using thermocouples (these temperatures are necessary only - no controller action based on them).  9219 module is ideal for my PID controller, that I can use to detect the very precise Thermistors, but it has only 4 entries.  I'm considering adding a NI 9213 Module to my setup to activate the additional analysis that I need...  My question is this - this module will be compatible with my setup?  for example can I simultaneously run two analog modules (9219 & 9213)?  Is it reasonable to try to make the PID regulation and this extra temperature monitors simultaneously?

  Thanks in advance for your comments!

  See you soon!

  Hello JB_1,

  What is are describing is undoubtedly reasonable and feasible with the hardware you have.  9178 has several Motors synchronization to analog input, so you can configure separate tasks for two different modules if you want to acquire simultaneously and at different rates.
