Description: This analog panel meter measures DC voltage from 0-5 volts with 2.5% accuracy. It has a clear and easy to read scale and an adjustable dial. These come in handy for measuring the output of sensors with 5V ranges.

The face of the meter is 45x45mm overall. The mounting hole should be 38mm. The overall depth of the meter is 35mm.

  • If anyone is looking for a printable template for the background scale, I have posted one here

  • I have created an Adobe Illustrator template for the background scale. I appreciated the other version uploaded here, but was looking for something with graduations and numbers/symbols I could change easily. It is linked here

  • I noticed that I needed a 9v power supply on my Arduino to make these go the full scale, the 5v supply I was using yielded only only about ¾ deflection at full PWM output.

  • Has anybody ever put together an Audio VU meter with this? I"m trying to put some together to build an analog mixer for my studio.

  • This would be good for a (analog) battery meter or a science project with solar power or a lemon/potato battery.

  • Hi folks, does anyone know where to find some sort of template for creating a cutout for this meter using something like front panel express

    Thanks

    • Check out the forum. I know we have had customers in the past mention doing this, so hopefully you can find someone through there who might be willing to share templates.

  • I’d really like a meter that had a range like -X to +X.

  • I am very disappointed with this meter. Not only does it NOT have a zero adjust, but the full scale deflection was over 6 volts for me. I Had to not only open it up to manually twist the assembly so that the needle pointed to zero, I had to change the resistor so that the meter was actually 5V full scale. I’m very disappointed that Sparkfun would sell such a low quality item.

  • Ok- no new posts but I hope you guys can help…

    Can I remove the background of these without damaging it?

    My plan is to make a clock with a couple of these, and replace the backgrounds with paper labeled 1-12 and 0-60 (maybe even a seconds or am/pm)

    Then I would use an arduino analog out to regulate voltage (I assume it is voltage, or should I get current version?)

    Anyways- thanks in advance :)

  • These are pretty simple to adapt as a voltmeter or ammeter over a wide range. The meter movement needs about 230mV for full scale deflection (fsd). The 5V version has a 5k series resistor to give fsd at about 1mA. You can adapt them for any fsd voltage above ¼ Volt by changing the internal series resistor. A multi turn trim-pot is the easiest way to get it right. 10k will give you up to about 10V, 20k for 20V etc.
    For an ammeter it’s a bit harder as you need a shunt resistor across the terminals to carry most of the current. Calculate the resistance to give 250mV across it at the current you want as fsd then add a low series resistor inside the meter to bring the fsd back to the correct point.
    I made a replacement 5A meter for my battery charger with a 0.05 Ohm shunt (two 0.1Ohm power resistors in parallel) and needed a 10 Ohm series resistor to get the correct reading.
    Works a treat.

  • I’ve been looking for these for months! Will they be back in stock soon?

  • Just got in a couple of these, they measure about 6.9K ohms. That would place it at about 0.72mA for full scale displacement. There is an internal resistor that you could change if you wanted different scale. I didn’t look at its value.
    Just a note, one of the two I purchased didn’t work. Opening the meter, the wire connected from the stud on the back to the movement had fallen off. I just resoldered it and it works fine. It is easy to disassemble these meters to change the scales or resistors.
    Mark

  • Um, how do you connect these to a circuit?
    There appears to be a line molded onto the back next to a screw, which might be a -, but there’s no +.
    Is it just the two upper screws on the back?

  • This looks like a great little component that you could use as a generic analog display. Any chance that background card is removable?

    • Its made of aluminium not card to keep it rigid(I think), I’m sure you could try card as long as you make sure its thin, Its about ½ a mm(I measured), The two small screws under the plastic screen are easy to get too, this component is cool, but is a little difficult when mounting. I think you need a little glue too for the top of the plastic cover as when you take it off the glue breaks(which I didn’t realize until I’d taken it off).
      Anyway Hope this helps :P

  • The product sheet show 0-250V, 0-2A, 0-20V, 0-50mA and 0-50ľA ones. Will you carry them someday?

  • anyone know where I can found a similar panel for 20 V?

    • Google Voltage Divider. They work amazing, I needed one to adapt an arduino to amp meter that pegged out at .09V.

  • Yay! I’ve been looking for little meters, they’ve gotten hard to find! LEDs are great, but nothing beats the swinging needle for that dynamic pulse. The 5V meter is just right to drive with an Arduino PWM pin, using analogWrite(). Looks like it can be opened up to put in a custom laser-printed scale. (Who will post a template?) We do need to know the sensitivity in ohms per volt. Thanks!

  • How much current does this meter draw, or what is the input impedance?
