The temperature of the led

I'm using a 1N4148 as a temperature sensor in a circuit of the thermostat (reverse engineering).   I want to manually to set the temperature of ONLY a component of the circuit, either in the simulation is running, or default between simulation runs.  The remaining components must remain at "nominal temperature.

I hope that the diode model will reduce approximately 2.3mV Vf / degree that I change the temperature.   I tried the model change for the part, but there was no field to allow me to enter (for example) T_ABS)

Just, T_ABS is the template parameter to change. If you are using a version older than 11.0.0 Multisim, then you won't see this parameter in the model of most of the components of diode parameters table.

I wrapped a 1n4148 in a subcircuit so that you have access to plain text to the model, in which you can specify T_ABS in the .model statement.

  • Satellite A350-212 on the fence the leds on my laptop

    Hello

    There are seven symbols that are related to windows media player on my laptop near the power button... I could close with touch first conducted before, but recently it does not work, I could not close all of the led or rather the power button close to ligtings on my laptop... I know that I don't have a big problem with my laptop but it is important to me, if you could help me with this, I'd be happy...

    Hello

    The first button turns on and off lighting
    I think you have some problems with the installed VAP (value added package).
    This is why I would recommend reinstall this package again
    Firstly uninstall the VAP system.
    Then restart the device and download the Toshiba VFR pilot European page.
    Then install again, reset the laptop.

    In order to get the FN button to work, you need to install the Flash memory card Support utility.
    If you use Windows 7, then you can download this tool updated Sat L500.

  • Satellite A300-1NO - webcam does not work, but the LED lights

    Hello!

    I have a laptop Satellite A300-1NO, with Win 7 installed. My problem is that my webcam does not work always, when I want to use it. Sometimes, it works perfectly in Skype, WLM etc... but sometimes I see a white or a black screen with a 'loading circle' in there. Blue is the LED light, I can see it in Device Manager too, but there is no picture, just 'loading '. I tried to uninstall the driver and then reinstall it, I installed the new "camera Assistant for Toshiba", without success.

    Is there any solution for this?

    > Is there any solution for this?
    I put t think there is solution for this. If I understand you right there is a problem with software pre-installed. It is not easy to say why this is happening.

    I have Satellite A300 too and use it with Win7 32 bit. Webcam works fine all the time.

    One more thing: have you noticed this problem in the first moments after installing Win7 or later?
    Have you installed something that may be the reason for this?

  • How can I change/turn off the led under the speakers on Satellite P100?

    How can I change/turn off the led under the speakers? (in Satellite P100 (PSPA6E))
    Now I see the light only in the left side, but when I bought the computer left and right led line lights blue under the speakers.

    Gazz's right. It is not possible to switch off the LEDs. If just one LED is on the other must be faulty. Contact the customer Service of your country partner. I'm sure they can disconnect one too if you n t need her.

  • Satellite Pro L10 will not start - the LED blinks

    I have a pro l10 phone which, after sutting down as battery not return to life. All I get is 8 flashes on battery led when the button is pressed. It's the same area only, battery only or both.

    It sounds bad
    Generally, the laptop LED flashes as there might be a hardware malfunction.
    The LED provide a microcode and the technician can read this code.
    A common user is not able to read. OK maybe you can read it, but you will not find any description about the meaning of the code.
    That is why it s a good idea to contact the technician in your country

    But as a first step, try this:
    Remove the battery and unplug the AC adapter.
    Wait 20 - 30 minutes and then plug in the battery and plug in the AC adapter.

    This is the only way to turn them off is off of the laptop and unplug. Otherwise, there is not another method to do. the orange is witness of the wifi, you can disable it with switch Wlan if available or pressing Fn + F8

    Bye bye!

    Hello

    It is a firmware simply displayed if no hardware problem have been located on the motherboard.
    The LED provides this firmware and only the technician can read this code.
    OK, you will probably be able to read this code, but you will find all the details on the meaning of the code.

    I found a useful description how to read such a code.

  • Turn off the LEDs in the structure of the case

    Hello

    I was wondering if someone could help me solve a problem in a software test bench that I am developing. I have attached some of my code in which the problem is visible. I have a business structure that is triggered by a 'push button '. I want the TEST that is currently RUNNING LED remain lit until the end of the execution of the case structure (condition true) then shuts down once it is completed. But the LED does not turn off and remains lit. Is that what I can do in the condition False to activate the LED is off when the code is not running. Please note that to run the program, you will need to "run continuously. I want until the led turns off after getting the 'result' so that the software operator can know that he is free to perform the next test. But now when the 'Start Test 2 "is executed after 'Start Test', the LED stays on.

    It might be a simple solution that I can be not familiar with, but forgive me, I am a new user of Labview and I could not find a solution to this online.

    Thank you.

    Kind regards

  • How can I manipulate a 2D led array so that the LEDs light up in different ways?

    Hello everyone. I hope someone can help me.

    I have an array of leds of dimension 2d 4 x 4. I want that the leds light up in two different ways.

    One, I want the leds light upward from left to right. In the following order:

    0.0 0.1 0.2 0.3

    1.3-2.3 3.3

    3.2 3.1 3.0

    2.0 1.0 1.2 1.1 2.2 and 2.1

    So in the end the entire table turns.

    The other, I want the leds light upwards from right to left. In the following order of the order:

    0.3 0.2 0.1 0.0

    1.0 2.0 3.0

    3.1 3.2 3.3 1.3-2.3

    1.1 1.2 2.1 and 2.2

    So in the end the entire table turns.

    Any help will be appreciated.


  • Turn on the LED for periods

    Hello

    I am trying to write a code that turns on an LED if a condition is met for five seconds.  Let's say I am to evaluate the slope of a curve.  If the slope of the curve remains greater than or equal to 1 for 5 seconds, then the LED should turn on.  Initially, I thought I could use a number of cycles or the elapsed time express VI, where if my slope become greater than 1, then the timer would start.  If the slope is less than 1 before the second 5 mark has been met, then the timer will be reset to 0 and start the next time the slope become greater than 1.  Help, please!

    Thank you!

    Using the elapsed timer express VI is a good solution. Use the reset entry as soon as the slope is located off spec.
