I finally got my ADC-16 working with an old PC that has a 15 way D serial port and am now trying to set up the PLW Recorder sampler. The problem I have is if I set the sampler to 1 minute it actually samples about every 6 minutes.
If I set it to 10 seconds the actual is 1 min 20 secs
If I set it to 8 seconds the actual is 1 min 5 secs
If I set it to 7 seconds the actual is 55 seconds.
The I can't set it to 7.5 seconds!
How can I get it to run for 1 minute exact?
I need this so I can work out how long the sun has been out each day at 1 minute intervals.
