Hello all!

My father is looking for the meaning of a symbol on his volt-ohm meter. It is an equilateral triangle, with a point straight to the right, and then a cross on the right, kind of like this: -|>|- but with the lines connected. The symbol is on the "selector switch" and is green.

Google was no help, and any suggestions are appreciated!

Techie husband says it's a diode checker.

Diode checker is pretty handy. When selected the red probe is positively charged and the black probe is ground. When you put the probes on the leads of a switching diode or LED the meter will tell you the voltage drop across the component. This allows you to quickly verify the polarity of a random diode from the parts drawer. What's really nice about it is you can confirm that the LED you just soldered in your design still works.

Thank you! And tell your husband thanks as well!
