1. Does measuring current with a clamp meter cause the meter to draw more power? In other words, if the meter is on but no conductor is inside it's clamp, does it draw less power than if it were on and there was a current carrying conductor inside it's clamp?
2. Does measuring current with a clamp meter cause more power to be drawn from the source? Meter loading. For example, you measure the current going to your dryer, does the presence of the meter cause more current to be drawn, even a very tiny bit?
3. If the answers to 1 and/or 2 are 'yes', is it possible that, if you had a mains-powered clamp meter, and you used the clamp meter to measure it's own current, would the current drawn increase exponentially due to the perpetual positive feedback, until the breaker tripped?
