st4000 calibration

[garethreeves]

I posted this on the raymarine forum site but am having no luck over there. Has anyone seen this before?

---

I finally got the display working on my st4000 and now I am trying to check the calibration settings. When I hold Standby for 5 seconds, instead of getting the calibration settings, I get a circular animation with the segments of the LCD display and then after a while I get the word Cal. After while Cal goes away and it goes back to C and the Heading. Does anyone know what this is? I don't see any reference to this in the manual.

Compass deviation correction mode seems like it might be similar but the animation appears differently.

Thanks

This is from memory but I think getting into cal mode is a 2 step process. When you see CAL you need to press the button again. (I think). My manual is on the boat and there is a huge thunderstorm at the moment and I can't go to the canal to look it up.

Thanks. I have the manual. (also available here http://www.raymarine.com/view/?id=1836) It says hold Standby for 5 seconds as long as calibration is enabled. I have been able to go through the calibration enable/disable steps fine so I don' think its that.

I'm thinking it somehow related to the initial sea trial and wonder if it does that when first installed. Is the circular animation telling me to go through the compass deviation calibration? According to the manual, I enter this calibration by pushing Standby for 1 second. Perhaps it wont go onto the rest of the calibration until this has been done?

Alternatively, perhaps its related to the fluxgate. I've have seen some postings about checking voltage from the fluxgate between the red and various other wires. I'm confused about this as well though since the fluxgate doesn't receive power except from the control unit. Do I need to somehow take the readings while its connected to the head unit? the spade connector covers are in the way...

Any help is appreciated.

Thanks

I don't know about the ST4000 but seeing what you describe on the ST4000 plus unit would indicate you need to start from the beginning with your setup. Go through the compass deviation calibration and do the slow circles with your boat as per the instructions and then see if you can continue the calibration process afterwards. I'm pretty sure that will take care of your issue. In any event, at least you could rule out that being the cause.

Drive in a circle slowly to complete the calibration.

Mine says to do the following to get to the seatrial mode to set the compass:
press 'standby' for 2 sec, "Display CAL" should be displayed
press 'disp' twice and "seatrial CAL" should be displayed
press 'auto' once to get to compass cal, "swing OFF" should be displayed.
press '+1' and "swing On" should display followed by lower left and upper right "corners" and "turn boat"
Turn in slow circles so the boat speed stays below 2 knots and each circle takes at least 2 minutes. keep turning the boat until you see the "Deviation x degrees" screen
Press 'disp' button and "Align HDG" should display
it COG is available from the GPS press 'auto' to set the autopilot heading to COG value (you don't want to be in a strong cross current BTW plan ahead so you end up pointing with or against the current)
if COG is not available or after setting heading to COG and you want to fine tune the heading for some reason) the use the +1,-1,+10, and -10 buttons to set the autopilot to the compass (or what ever you want) manually
to save changes press the 'auto' button for 2 seconds. the unit should return to standby mode after that.
Good luck, the first time I did this it took me three tries.

Thanks Bill. It sounds like you have the St4000+ not the older st4000.

Actually the ST600+ but the three other Ray APs I've had where all very similar. seatrial was a two button operation in all cases.
Give it a try and see. in any case you can't hurt the unit by pressing a wrong button. May need to factory reset if it gets all FUBAR and start over.
standby and auto seem to be "mode" or next screen buttons and the +- buttons are to set things on that screen. after a while you will develope a "rayspeak" button knowledge.
