Analog Panel Meter - 0 to 20mA (Ding and Dent)
Replacement: None. This analog meter was only available for a limited time, we are no longer carrying it in our catalog. This page is for reference only.
This analog panel meter measures DC current from 0-20mA with 5% accuracy. It has a clear and easy to read scale and an adjustable dial. These can be useful for measuring the current on the GPIO pins on your microcontroller or numerous other applications. To be honest, these meters work just fine. The only problem we have with them is that our supplier did not have enough milliamp scale backers so they, instead, used amp scale backers with the "m" painted on to the left of the "A." Are we the only ones who think that "m" looks like it should belong on an M&M? We've dropped the price on this meter, so if you don't mind a painted "m" over a printed one instead, then this is a good buy!
The face of the meter is 45x45mm overall. The mounting hole should be 38mm. The overall depth of the meter is 35mm.
Note: The panel meter includes mounting nuts and washers.

Robert,
It could of been worse I suppose. They could of shown up looking like this:
:)
Still, useful meters!
Looks like that meter came from the Milwaukee Art Musium, obviously.
HANDPAINTED? all of them? I hope the proceeds of this goes to the person who had to do the painting - because I am sure they are suffering walleye syndrome now.
Looks like we are being warned about ... something to do with 2.5 ... on the lower right. What exactly is that?
First symbol - for DC measurement.
Second symbol indicates that it's a moving coil type.
The 2.5 is its wikipedia:class value.
The third symbol is probably more a "pay attention to this when reading values" thing than a "danger will robinson" thing.
Edit: Was hoping to find a nice reference overview other than my crappy old schoolbook, and a random manufacturer (ESP Technologies) delivers: NOVA PANEL METER(ANALOGUE) - Page 2: Symbols for Marking Instruments and Accessories.
Which in turn tells me that the third symbol does have a defined meaning: Warning: see application instructions.
Any spec of the burden voltage of these?
Can these be easily opened to replace the panel?
yeah, it's pretty easy. two screws on the bottom to get the face off, and then two more screws to take off the face.
I wasn't going for that, but I wish I had... that's perfect.
See the screws? That's usually pretty much it. The panel may also be glued down, often making it impossible to remove it without bending it or having lots of patience + glue dissolve.
Look good boss? Yah! Yah!, they wont even notice! :)
haha, right?
