Is this proportional or timed?

It is controlled by the setting that you set for your particular vehicle and trailer you are towing. The control knob is on the side of the unit once you set it to the stopping power required you will feel the trailer brake stopping you. if you start and adjust the power from 0.0 to 2.0 it should work with your tow vehicle. Exact amount varies but this will get you close to where the setting on the controller should be. Note the controller does not light up without being attached to a towable load attached to your vehicle.

No, ours runs for as long as you set the time. Longer than 30 min if set that way.

Not sure, I've never timed it but I would say about 30 minutes and you can use it again.

I haven't timed it, but there is a delay. Around 1 second or more. I have trouble making the timing work with my harmony remote, if that's what prompts your question. It's not easy to program the delays with the harmony software. I also have a Monster MDP-900 which has almost no delay.

Hi, Thanks for your inquiry. If it is fulfilled by us, then handling time is one day. if it is fulfilled by Amazon, then that depends on them. Fraidy

not exactly sure...my husband adjusts the time with the buttons on the bottom of the scale.

A minute is the smallest marked increment of time. You could probably do less, but it would loose accuracy.

No. it will not count up or down for more than nine hours, 59 min's. and 59 sec's. The timer was designed that way.

I am not really sure but within several hours. I've never really timed it. I just know I can continue to use it and it increases in charge.

I used it for an event that lasted about 3 hours. Don't know about the other questions.

I just started using it-time will tell. Sorry I could not provide you with an answer yet.

I've never timed it, but its probably 30-40 seconds. I've been using it for measuring hair color and I have to remove the bowl with color in it while I get the peroxide and then put it back on the scale and pour the peroxide, otherwise it will shut off and I have to guess as to how much more color or peroxide I need. Had a few hair situations - no pun intended - where I've had to guess at the amounts. It seems to want to shut off when there is no immediate activity as in that I'm not putting anything into the bowl. I love the design, size, price, but I wouldn't buy it again.

I have not timed it but it is very short, just a guess but maybe 20 seconds. It is very easy to crank - it is a great system. Ken

Hey Mavis, Sorry, but I've never 'timed' it. I just fill the kettle, set my surface burner to a low level, and do something else while I wait for the whistle. Royfill

It cannot be used as a calculator and there is a mode without the timer. I have never used Math Whiz so I can't answer that question.

I never really timed it, but I'd estimate 10 seconds or less. This thing actually works!
