Question about La Crosse K2-100 Wrist Watch

1 Answer

Incorrect altitude changes

First, I am aware of the changes in barometric pressure affecting the altitude readout. That's how the altitude is calculated in these watches. However, after a year of satisfactory use with very accurate altitude reading (I usually calibrate the altitude measurement at a trailhead or when I'm at a summit) this watch no longer works. I get an altitude change of around 200 feet or so for a real altitude change of around 400'. I may get a change of 1/2 the actual change in elevation. Very frustrating. I was going to trash it but I couldn't understand why the altitude readings are so far off when the barametric pressure readings are accurate? And they are VERY accurate! I've changed the battery - no difference. Also, the graph no longer functions for altitude. I guess you get what you pay for but I feel let down by this watch. Any help?

Here is the link to the user manual for this watch if you need it; http://www.lacrossetechnology.com/k2100/manual.pdf page 12 gives you all the contact details for lacrosse. I couldnt find the info online to be sure, but some of these watches do have a separate pressure sensor for altitude and barometric pressure, and sometimes the path to one could get blocked or it could become faulty. I would contact la crosse and find a dealer to get the watch serviced, you could probably do it yourself but you need to get replacement seals from them anyway (these are important). ask them to check if the sensor is clogged, it happens sometimes. Hope this helps :)

The altimeter on my Timex Helix reads LO and can't be changed. I changed the battery -- anything else I can try?

Timex Helix ABT.
This watch calculates altitude by measuring air pressure and relating that value to the international standard atmosphere. 1013.25 mb = 0 metres.
The Timex ABT does not display negative altitude values. So if the measured air pressure is greater than 1013.25 mb and the altimeter is reset (select altimeter, pull out the crown 1 click and press and hold the lower left button) the watch will display LO. You can experiment with this. Wait till the barometer reads 1013 or 1012 and reset the altimeter. The watch will display zero or maybe 5 metres. Or wait till the pressure goes up to, say, 1022 and reset the altimeter. The watch will read LO again. If this happens alot, you probably live fairly close to sea level. What you can do to trick the watch is use a vacuum cleaner to raise the perceived altitude of the watch then calibrate the altimeter (pull out and rotate the crown) and change the altimeter reading to, say, 200 metres. It wont read LO then. Keep an eye on it and the atmospheric pressure. If the pressure starts to rise then adjust the altimeter accordingly. Remember this watch is designed to measure proper altitudes where the air pressure isnt likely to be as high as 1013.25. If you are mooching around near sea level the naturally changing air pressure will often make the watch read LO.
If you live up in Montana at 1500 metres (ISA standard pressure about 840 mb) all the time then the watch will always read a positive value and you can calibrate it from reference to a map or road sign etc. The atmospheric pressure will unlikely reach as high as 1013 up there and the watch wont read LO.

I have a Suunto X-Lander and i dont get along with the barometer/altimeter. The barometer always shows about 2 mbar below the nearby airport homepage. Can i by myself calibrate the sensor? This even...

Erik, the altimeter uses barometric pressure to determine changes in elevation. Rule one is whenever you know the elevation for a fact, adjust it as the barometer is changing often and therefore affecting the altimeter reading. The only sure way to avoid this is use GPS. Altitude is derived from locating 3 or 4 satellites in a geo syncrohnus(SP?) orbit. Pilots always reset the altimeter before take off and you should too. Find elevations on road signs, maps, etc.

I calibrated my Timex WS4 using a known barometric pressure and set the weather conditions but the watch is telling me I'm at an altitude of -42 meters (which I'm not) and the temperature is at least 10...

You should carefully read the manual on this watch. It is a very sophisticated instrument realitive to its cost.

The barometric pressure in the CAL mode is set to the reference sea level. The pressure that is read in the other areas is the actual or relative pressure at your location.

There are some tollerences for the accuracy of these watches. What they are excellent at is seeing the relative differences or changes. I found that when I set the reference barometric pressure (Sea Level Pressure), everything falls in to place. I found the WP4 to be accurate to within about 15 to 20 feet accuracy for altitude most of the time. It is important to periodically check the barometric pressure from the weather office if you want it to be as accurate as possible.

When hiking or out trecking, it is advisable to check the watch's altitude relative to the map that you are using, or to a known reference. Then as you travel you can check for the altitude change.

Take care that this type of watch is to be used as a quick or easy reference only. It is not certified to be used in situations where life and safety are fully dependent on the readings from this type of watch. It is a precision instrument, but not as precise as the high end professional certified types. It is best to refer to proper maps (charts), and depend on a certified mechanical compass for absolute reference.

How does the altimeter function work? we can't find it on the enclosed instructions

Altimeters on watches are usually based on barometric pressure, since the pressure changes all the time you generally need to adjust the altimeter to a known altitude. You can look on USGS website to find the altitude of your area, or simply type in "altitude of city, state" in a search engine.
I hope I understood your question; if not, please reply.

Altimeter setting creeps up on Suunto Vector

It sounds like IC (integrated Circuit) in your watch is mulfunctioning, but can be something else. Can't say without inspection.None of the readings mentioned by you is acceptable.
As the watch is purely microelectronic, there is nothing you can do but to take it back to the retailer and ask for repair or replacement. If your watch is just 10 days old, this must be done under warranty and at no cost to you.
Don't forget to rate, please.

Alti does not read correct alti.

Don't forget that the altimeter is barometric, and therefore the altitude reading will change depending on the air pressure - i.e. the weatherman may give the 'high pressure coming through' or that there is a low pressure giving rain - to get the true altitude, you need to know the true air pressure at any given point on the earth ~(where you are) then set this as the 'normal'. you will then get the correct altitude. Don't forget that if you are in a pressurised aircraft - as in allcommercial flights, the cabin air pressure is artificially kept at appx 4000-6000ft altitude

Adjusting meteo function

Yes, Sir. But remember when pilots reset their altimeter with the local altitude, the pressure value matches the moment wheather pressure. It will be wrong anyway, if you reset you altitude, but the pressure readings are still wrong. Im my case it is happening. The altutide is correct but the pressure of the watch does not match the local pressure. It is 20 hpa over it. By the way, I am an airline pilot.
