| | | It is indeed PWM. I got out my oscilliscope and checked it, and here are the results I got: At setting 1 (closest to off): Th: 1ms Tl: 2ms Tt: 3ms 9Vpp At setting 2: Th: 2ms Tl: 1ms Tt: 3ms 9Vpp And at full on, it's just 9v DC. (...) (22 years ago, 29-Dec-02, to lugnet.org.ca.rtltoronto)

| | | | (...) cool. Thanks Trevyn. now if only I had an O-scope and knew what Th, T1, and Tt meant?? ;) Chris (22 years ago, 29-Dec-02, to lugnet.org.ca.rtltoronto)

| | | | (...) Th - Time signal is High Tl - Time signal is Low Tt - total time ------________ Th Tl <---- Tt --------> Matthias Jetleb P.S.: Th/Tt is defined as the duty cycle, expressed as a percent. Therefor: Th=2ms, Tt=3ms = 66% duty cycle. This is (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)

| | | | Still no baby..... (...) umm, thanks Matt.... but I did put in the winky face after my last statement.... and since you did bring it up my DMM does do true RMS. that's why I have never felt the need for an o-scope. my electronics projects just don't (...)
