 Topic: T6c altimeter and temperature Posted: 05 Jul 2010 at 14:25 |
|
I know plenty of people have commented that the T6c's altimeter keeps needing calibration and, of course, that's the very nature of a baromtetric altimeter as opposed to, say, a GPS unit.
However, has anyone else noticed how the altimeter also seems very sensitive to temperature? I've noticed this quite a few times now that it's winter down here in Australia and there's a decent temp. difference between inside and out.
eg, went for a 45min run tonight, weather is dead stable, it was 20 degrees in the house when I left, 26 on my wrist, 4 outside. In the first 12 or so minutes of the run the watch artifically "gained" 40m of altitude as it dropped in temperature from 26 down to 12 deg.
How do I know this? Because the start of the is dead flat and the watch still had that 40m of artifical gain when I returned home 33min later and the watch was still at 12 deg.
Even just taking the dog for a 20min walk around the block with a long-sleeve top on results in a 20m difference between start and finish.
I know that temperature changes do affect how a barometer reads the air pressure, but the previous two altimeter watches I've had quite comfortably accounted for the change in temperature when showing altitude, while the T6c seems to not even bother?
Is it just my T6c that seems to suffer so badly from this?
Is the X6HR's altimeter better at handling altitude?

If you have these problems, probably your unit needs service
I had a similar problem with my first T6c. In my case altitude rose abruptly with temperatures over 25º. I live in Spain and in summer temperatures over 30º are quite normal. Therefore I got very strange altitude changes in my trainings unit and the cumulative altitude was around 50% higher than reality.
As long as I know, altimeters need an intern calibration (different of the "normal" barometric calibration) in order to work correctly with changing temperatures.
I sent mine to Suunto with some data of the strange altitude values and they replaced the watch
Cheers,
Rubén

Got a response from Suunto saying "Let the watch get cold first, put it back on, set the reference altitude and then use it".
Basically they're telling me the T6c uses a cheap electronic altimeter that's more sensitive to temperature change than a more expensive component?
I suppose you're average punter is more interested in other features in the watch and isn't too worried about the quality of the altitude reading.

Hi again,
In your case, I would insist and send to Suunto many different training units with "crazy" values for altitude.
As I said, it is no normal, my current clock works without Problem. They have to repair or change your unit!
You can also make some pressure to your local retailer. That is what I did and it worked!
Cheers and good luck!

Just some words for bad altitude: I bought a the red arrow t6c just about one year ago. After some weeks I got problems with altitude recording and a strange up and down of the graph. After sending it to Suunto in November last year (stupid for waiting so long...) I got a new red arrow. Just four weeks later (February this year) the same annoying thing. Contacting Suunto helpdesk I was told there is no solution at the moment (hardware problem). After waiting* another quarter of year I wrote to Suunto again. Now I was told (after weeks) to send the clock to Suunto cause they will change the soft(!?!?)ware. At the moment the t6c is at Suunto... I will wait and give you the information what will happen in future. *) meantime I am running with my old t6 classic which I have more than five years without any problems in counting the altitude :-(
Sorry about my first writing in this forum (you can also find articles regarding Suunto t6(c) in Internet Foren by "JoggWithoutDog" - cause it wasn't allowed to take this name for this forum

Thanks for the advice guys. I'll persist!
...although I think I'm happier with inaccurate altimeter readings than I would being without my T6c for at least 4 weeks! :)

Yesterday I got a mail from Suunto in which I was told to get no longer guarantee. I tried to answer but got always the same "error" for sending. Other mails worked!?! So I give my answer in this forum just to inform other interested people and maybe Suunto will read this and think about their unsatisfying answer... Here it is (at the moment I am more and more convinced to change over to Polar or Garmin - after years of staying at the side of Suunto (look in internet: my sayings are posted by "joggwithoutdog"): Sehr geehrte Damen und Herren, nachdem mein Ärger sich ein klein wenig gelegt hat, versuche ich heute ein letztes Mal meinen Standpunkt zu erklären und bitte Sie, mir diesbezüglich nochmals eine klare Antwort zu geben: Fakt ist: 1. Ich habe eine Red Arrow, bei der bisher (auch beim Austauschgerät) der barometrische Höhenmesser - bis auf die wenigen Läufe zu Beginn bzw. kurz nach Austausch - definitiv nicht funktioniert. 2. Ich wurde von Ihnen informiert, dass es sich um einen Hardwarefehler handle, der derzeit nicht behebbar sei (Mail vom 25.02.10) 3. Keine Antwort - auch nach meiner Bitte, wenigstens einen ungefähren Zeitrahmen zu nennen, bis wann dieses Hardwareproblem gelöst werden könnte. 4. Nachdem keinerlei Antwort mehr kam, versuchte ich mit meinem Mail vom 26.05.10 nochmals mein Glück. Wenn ich bis nach Ablauf der Garantie gewartet hätte, wäre sie erloschen - aus Ihrer obigen Antwort zu schließen, oder? 5. In Ihrem Mail vom 02.06.10 erklärten Sie mir, ich solle die Uhr einschicken. 6. Daraufhin bat ich um Details, was gemacht werden soll und erhielt die Aussage (15.06.10), dass die Software(!?!) geupdatet werden soll. 7. Mit gemischten Gefühlen schickte ich die Uhr am 06.07.10 zu Ihnen und warte immer (17.07.10 ... 11 Tage später) noch auf die Rücksendung.
Erklärung meinerseits: Ich bin selbstverständlich bereit, die normale Garantie für die Uhr anzuerkennen - aber nicht bezüglich des barometrischen Höhenmessers (obwohl ich die Uhr selbst ja auch nicht wirklich nutzen konnte...). Ich bin nicht bereit, dies für einen nicht oder nur Wochen funktionierenden Höhenmesser anzuerkennen. Ich erwarte bei Rücksendung eine Uhr, die hier funktioniert und biete Ihnen folgende Möglichkeiten: Red Arrow - funktionierend (woran ich meine Zweifel habe...) Andere t6c - mit entsprechender Gutschrift, sofern billigeres Modell t6d - ggf. mit Aufpreis, da ich die Red Arrow ca. 4 Wochen nutzte.
Bitte teilen Sie mir Ihre Antwort bis spätestens kommenden Donnertag/22.07.10 mit.
Ich werde mich dann entscheiden, ob ich a) es einem Rechtsanwalt übergebe (zum Glück habe ich sämtliche Aufzeichnung der Red Arrow sowie alle diesbezüglichen Mails gespeichert). b) dann sofort zu Polar oder Garmin überwechsle und c) dies in den Foren, wo ich bisher nur(!) positiv über die Hardware von t6(c) berichtet habe, publik machen werde. Vielen Dank für eine Antwort. Joachim Kopic alias JoggWithoutDog alias JogWithDog
Bitte beachten Sie die Frist bis Do/22.07.10

Sorry but I forgot to translate in English: Dear Madams & Sirs, after "cooling down" a little bit (very angry about your saying regarding guarantee) I will try the last time to explain my position and hope to get a clear answer from you: 1. I have a red arrow which altitude measuring (also the changed red arrow) definitely don't work - only the running logs at the beginning and shortly after changing the red arrow worked. 2. You informed me that it is a hardware failure and couldn't be solved at the moment (your mail 25.02.10) 3. No reply - also not after my please to give me just a "about-date" when the hardware problem will be solved. 4. After no reply till May I tried an additional mail (26.05.10) ... If I would have waited till after guarantee - there wouldn't be guarantee, would it? ... 5. In Suunto-Mail (02.06.10) I was told to send the red arrow to Suunto again. 6. I asked for details what they will do and got the answer (15.06.10) that the soft(?!?)ware will be updated. 7. With mixed emotions I sent the clock to Suunto (06.07.10) and still waiting for the return.
Declaration myself: Of course, I say the normal Guaranteetime is OK - but not for the altitude failure (even I can't use the red arrow really) I am not willing to say OK for an altitude measuring which only works for some weeks. I must have a returned clock with OK of altitude measuring and offer you the following possibilities: Red Arrow - All(!) functions are OK Other t6c - with a bonus if this modell were a cheaper one t6d - you can offer me a amount I should pay because the red arrow was used by myself for about four weeks.
Please write me your answer not later than Thursday 22.07.10.
Then I decided if I a) take the whole story to a lawyer (luckily I saved all the good/bad tracks of the red arrow and the mails regarding it). b) if so I will change over to Polar or Garmin c) I will post then your decision in all "discussion-centers" where I've never written negative about the hardware of t6(c). Thanx for your answer Joachim Kopic alias JoggWithoutDog alias JoggWithDog
Please think of the latest time of sending: Thursday / 22.07.10.
I have to declare to see no other change to arrive Suunto cause all mail tryings were interrupted - also to post a new asking to Suunto as a customer. Sorry but now it's your decision, Suunto Helpdesk...

I promised to give informations after there will be interesting news: Sorry, but there are bad news: Last Sunday Suunto told me to have send back my t6c red arrow - on last Tuesday (20.07.10) the clock returned. On Wednesday I tried the first walking and running. Even at the first try I had the same problem like before sending. Because of "swinging of the altitude figures" the log shows about 10 times higher sum of descent/ascent than in reality. At the same evening I did a 11 km run - better but also sometimes the "swinging failure". I will test the red arrow a last one on Sunday but I guess the same worse result :-(((( . The crazy thing is that if I use the clock as a clock the altitude are mostly constant but the moment I start a recording mostly the "swinging" starts. It seems to be really a hardware problem of the red arrow (or was it really only the two gadgets I have - you remember: first clock since August last year and the "new" one changed at the end of 2009- I can't believe. I will try a last recording and then contact Suunto again - very annoying. JoggWithDog alias JoggWithoutDog alias Joachim Kopic PS Of course, Suunto didn't give me an answer to the above mentioned writing :-( I guess I will change back to Polar but I can't accept to remain silent - the right is on my side (see above). Will send new informations when I will have finished the long run on Sunday.

It's crazy: Today I did two runs with my red arrow and the normal t6c grey one - believe it or not, the red arrow did a good job - even better then the "grey". So I will try another run on Monday/Tuesday - will give you the new information.... JoggWithDog / JoggWithoutDog / Joachim Kopic
