Wow, I guess that technically still belongs in the PWM category but yeah, even the longest length of nichrome won't have enough induction to keep the current down on that puppy. Even without a scope, you could get a rough idea what kind of controller you have using a volt meter. Plug the clothing in with the controller in-line and measure the voltage. If the pulses are 5 seconds duration you'll be able to count them! But if it's a more traditional PWM frequency of many KHz, then the voltage should remain relatively stable at the various settings (give or take a few tenths, depending on the frequency response of your meter). If it's resistive, the voltage will follow the settings (ie: low voltage at low settings, rising as you crank up the heat). (Or, if you are ever in Muskoka, stop by. I have several scopes to choose from)</blockquote>
