Does it give a 0 reading when turned on? This is the one my ex bought to prove he's sober but I've never seen the unit and want to make sure

The BACtrack S80 Breathalyzer with Extended Sensor does not give a 0 reading when turned on. You would need to give a full breath sample with no alcohol present to get a 0 reading.

No. It does not give a 0 reading when turned on. It starts a countdown from like 10-0, then displays start, that's when you blow into it, and then it makes an audible sound, that's when you stop blowing. In a few seconds it will give the BAC. They are extremely accurate. Each time you use it, it counts that use. So everytime you use it , it will show the number of times it has been used.

Just turned mine on to see. It counts down and then you blow. Didn't see it zero out.
1150765
no. when its turned on it starts a countdown from 15 seconds,then you blow until it clicks and then it gives a readout.only if no alcohol is in system will it give a 0 readout

The BACtrack S80 will display a 0.00 reading if the user takes a full breath sample and there is no alcohol present in his system. If you have any questions about how to use this device, please consult your owner's manual or contact us at support@bactrack.com.

Yes it does. And it's pretty accurate, you can turn it on or off. User manual is extremely incomplete and confusing though

Mine works 100% fine. Never encounter anything. Your unit might be defective.

It seems to calibrate itself upon startup. It will calibrate itself to zero if you turn it on with a container that you intend to fill already on it. As for it's need to be calibrated for accuracy, we'll we just have to trust to the gods of electronics. That said, I've never felt it might be even slightly beyond negligible where error is concerned. I'll buy another if mine ever poops out!

The one I bought had one. No longer have it to check now. But it did. Good unit.

i think when u turn it on it zeros itself. Otherwise I can't find a way to do it

I have not had any issues, but the DW(Distilled Water) I use reads in the 0 to 9µS range- which would show 0 on the mS range.

Not entirely sure myself (I can't find the blasted manual). My first guess would be the indicator is reading above its max range. I'd suggest rinsing off the metal tip in case there's something encrusted on it. Also, if it's looking rusty it might be time to replace it. Another possibility is the battery is low though I figure it'll just stop working or the display will be faint.

I just turned it on and started using it. I have never checked it actually.

It does negative values. When you turn it on, it zeroesI've done that when at 1200', so it reads -1150 when I get home.So I assume it will.

I am not familiar with that reading. My unit has worked like a charm. I would suggest that you go to the vendor's website. Maybe someone else has experienced something similar. Good luck!

Unit is on when ignition is on regardless of whether or not a trailer is hooked up. if no trailer is detected (connected) it will flash a brief message that no trailer is connected. Unit display stays on for 15 minutes after ignition is turned off. Has not been a problem in my F150 thus far

Sorry but I never "tested" it without batteries. The display shows both readings which stay lit for a few seconds-I would think battery drain is minimal.

I tested it with the meter and saw very little in difference in the number. I took it out and replaced it with a zero water pitcher. Big difference. I'm sold on zero water. By the way the reading was 62 with the brondell from 68. Marietta Water

Don't know, and don't care. This was one of the worst purchases I've ever made. I bought it several months ago, and in a few days, the Low setting would stop working. So I left a message asking to replace , and didn't hear anything back from them. If you've used for 6 months, I'd say you had it running longer than expected, and it's time to find another one, probably not from them.

Got this for Xmas Yesterday to measure speaker ohm's. it say to shot the two prongs together to read 0... Not on mine, its says 1.1-1.3, So to me, its junk because i need to it measure 4ohm's and below. its going back!

I have used it on my daughter and usually she is .08 or higher, and she has been at 0.00. There hasn't been any in betweens because she's usually really drunk or not drinking. It's been very accurate so far.
