I purchased a 10 turn 1K pot to replace the stock pot on my K40. I also purchased a high accuracy digital milliammeter. My question is, can I just run this ammeter in series with the existing analog meter? Will this have a negative effect on laser power and PWM performance? The digital one I purchased is able to connect to a separate power supply for operating voltage. A link is attached.
I am trying to get a readout of current settings other than attempting to read the analog needle.
