Red LED Frequency/Counter Panel Meter
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.

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.
Joe, I may have confused you in the description. The generator IS a pure sine wave-voltage regulated 5KW output.The issues has not gotten to the generator, I can't even measure the frequency in the house. The meter is working. It measures perfectly with in its range when I use a frequency generator, including 60HZ, but when I want to measure 60 HZ from household current, reduced to 4.5VAC (so as not to fry the meter) the meter recognizes the first display and locks there. I must remove the test leads and reconnect in order to get the continuous fluctuations. Hope that helps.
