do you have to continually hold a button for it to read or is it a timed interval?

I work as a Registered Respiratory Therapist this device is a part of my everyday quick check for patient monitoring and assessment. To answer your question, no there is no button. When the device is placed on any finger or thumb it will automatically come on. The infrared located within the device picks up the pulse circulated through the blood and read an approximation of the individual actual oxygen saturation and heart rate. These reading can be + or - 2-5 off the normal ranges. These ranges depend on the individual disease process. For a more accurate result a arterial blood gas needs to be performed.

No need to hold a button. It holds your fingertip like a clip. It continually updates the measurements as long as the finger is clipped.

You need to hold the button down. I prefer this to a "double click" approach.

Great query I shall try to help you though I no longer own this unit due to the fact that it had some broken parts that only got worse until it stopped working? I believe you need to hold the upper button down until it progressively blinks and/or beeps/vibrates one level at a time. Alternately, it maybe the lower button?Either way you'll need to experiment by testing the timing option much the same as short and/or long pressing buttons on say a tablet computer.

I assume you mean the watch is announcing the time every hour without the button being pushed. Unfortunately, I don't have an answer other than to read the instructions very carefully. If you've lost the instructions, you're screwed to put it bluntly. The process for setting the watch up is complicated even with the instructions on hand. I've bought two of these watches for a blind friend. They would announce the correct time and date when the button was pressed but I couldn't get either of them to display the correct time.

Why would you need to do that? The watch only speaks the hour if you touch the button to hear what time it is.

I didn't get one with mine, I just looked at picture to make sure I had it in right. Then you just press the middle button and it will start, when it get through it will give you a reading and turn off by itself, it also stores your reading. I really like mine,

No, it won't automatically do that. If you're near it when the timer goes off & push the red button to stop it. You can then push the Start/Stop button & it will begin a count UP. I'm thinking it will keep counting up till it reaches the maximum. But, no, it won't start a count up automatically.

Sorry for the looooooooooong delay in answering - It repeats for a about 1 minute. Hope you bought it - It works GREAT and the four timing options are very useful.

I takes about 20 seconds to get to the full temperature reading. Not instant read.

I set it once based on the instruction set (which I don't have anymore). I think you have to press and hold one of the buttons for a few seconds to set the minutes and press again to set the seconds. Not sure which button though. Good luck. My clock ran 5 minutes fast everyday so I've just ignored it since then.

Doesn't seem to be... it is all digitally controlled, I dont have to do anything except not overfill and push the button. It turns off itself because everything is timed. I am using it a lot and no problems at all so far.

The device reads in either inches or mm. Hold button down until display flashes and then press again and it will switch.

Use the Min/Max function. When it's blinking, activate the circuit and then cycle the Min/Max button to read values. Keep in mind, if you have the clamp probe turned the wrong way a negative value may show as "Max." Hope this answers your question

Do you have the timer button pressed when you have the timer on settings on?

Pretty sure you would have to continually re-set it to start over again. It pumps up, releases, displays your reading. You could certainly just continually do that for an hour or two thus getting readings every minute or so.

You can leave it on but it doesn't read continuously. You have to press a button to get the current reading. Therefore, there is no point in leaving it on unless someone is going to press the button and check on it at intervals during the night.
