Use J6 pulse to drive analog meter

Post by kg6am »

Can I use the J6 pulse to drive 50 microamp analog meter ? I have tried using a TLC272 chip based circuit with no success.

I'm not familiar with the TLC272 but will check out the datasheet. What circuit are you using? Can you post a schematic?

I suspect that if you are seeing no indication on the meter, the pulses generated by my kit are too short to use with that circuit. Try lowering the resistance in series with the pulse output and see if that makes any difference.
