No especifica el tipo de señal que admite el equipo (tension, corriente, frecuencia, etc). Hemos intentado utilizar el contador con una señal que cada 20 segundos su voltaje es cero y el contador registra muchos eventos por cada evento real.

The Canadian customer used relays. Relays have what’s called bounce , when the contacts close the voltage rings high low rapidly this causes your miscounts. When I get mine I can solve that for you #metrontwit send me a message should have mine this weekend. I’m puzzled with pin 5 for now it may be an output signal showing the counter has changed

It's trivial to print pin outs on the box or paper label on the meter. Using Google Translate I've even deciphered Chinese labels. So yeh it works after finding the proper pin-outs somewhere on the web (or a review here)! Update: see the review where pin-outs are explained, but that buyer fried one before figuring proper connections for function. Even a spec sheet in another language can be translated, but not included. Unless you are buying large qty to install these in other devices for sale the poor labeling and no reference to a spec sheet is damn good reason to avoid. Buy a different one.

I purchased 4 of these, wasted one learning how to connect it. The instructions are terrible. I wanted to use them in my production presses, to count cycles per hour (1,000). But every cycle it will count 2 or 3 pulses at one time. I try adding a capacitor 470pf by the contact switch, it improved a little, but it will some times still jump 2 numbers. I have try every thing, shielded cable, installed a relay as near as possible to the counter. None of them work properly. A big waste of time and money.

I previously bought this item and connected it incorrectly causing damage. For those who find the information confusing here is the correct instruction for making connections. After buying a second counter I figured out the proper way to connect this Counter Meter is as follows:Connect terminal 1 (positive) and terminal 2 (negative) to a 8-24Vdc supply.1. If to want the count to increase, connect terminal 5 (switch pulse signal) to 6 (blue wire) and connect those through NO switch contacts to terminal 3 (signal ground).2. If to want the count to decrease, connect terminal 5 (switch pulse signal) to 7 (black wire) and connect those through NO switch contacts to terminal 3 (signal ground).3. If to need to reset the count, connect terminal 4 (clear) to terminal 3 (signal ground).Hope this helps other buyers.
