Red LED Frequency/Counter Panel Meter
I need the diagram connection for this frequency meter
A diagram can be found in the manual below.www.parts-express.com/pedocs/manuals/320-538-sure-electronics-manual.pdf

Using a frequency generator, inserting the range of what this will handle, output must be at 0 DB. It works and is responsive to any frequency shift. However, I need this meter to measure the output of voltage regulated generators that produce 120 VAC where the frequency should be at 60 HZ +/-. I'm using a low voltage step-down transformer, from 120 VAC to 4.5VAC to meet the meters range and find this meter will lock on to the first hit, i.e. 60 HZ and never change.I'm testing the same frequency as in the home with a Fluke multimeter on the same leads. That meter fluctuates constantly. In order to get a constant reading with this Sure meter, one must repeatedly connect and remove the test lead which will then display the latest measurement.The meter works, I'm just not sure why it doesn't read low voltage AC frequency when compared to a different meter. Do I not have enough gain, too much gain, somethings missing and I need help. These meters are perfect for my project and would love to use them. Any help appreciated.
You need a "TRUE RMS READING" voltmeter to work on a generator. Generators--unless they are high end--usually send out a "SQUARE WAVE" 60 cycles per second. Or a "STEPPED SQUARE WAVE". They work great on power tools but are limited where electronics are concerned. A "TRUE SIGN WAVE" generator will work pretty well for your project--except for the cost. Try a different volt meter that reads RMS.That is the lowest cost option.

I'm building a pickup winder, will this led panel work as a wind counter with a reed switch or is it only a frequency counter?
Unfortunately this will only work as a frequency counter.
