 Posted: Sun Oct 17, 2010 8:24 am Post subject: How to set my accelerometer? |
 |
|
Hi
I have a problem with my rear accelerometer on a yak52.
It shows on the ground a solid 2G instead 1G.
In the instruments back, there is 3 small screws and a big one.
Can somebody tells me how to set the instrument accurately?
Thanks
Olivier

Olivier I had a problem with my G-meter a few years ago and took the back cover off, mine the interior was made of brass kind of like a clock and vibration over the years just wore it out I took the back G-meter out and put it up front and I had another meter to put in the back you do know that the front g-meter is also a switch and when you exceed the G limit a buzzing sound goes to the headset telling you to knock it off your exceeding my G-limits.

Thanks for your answer.
So you mean that the best way is to replace it?

Yes if its worn so bad that it will not return to 1 g after a flight and gives erroneous measurements in the air, the rear cockpit G-meter is not wired to the aircraft and doesn't need the switch. But keep in mind that the Yak 52 G-meter has a switch in it, it is wired in front cockpit and front and rear meters are the same. I had to something with mine because the buzzer kept going off.
Does the GIB really need a G-meter?

Ok
Roger that.
In fact it’s a good thing for me that the GIB have a Gmeter……I’m still learning aerobatics so my instructor can read the G’s in the back seat.
Now I understand why I see all in black when the GIB pull a loop J)))
Thanks

Olivier,
As a wild card you could check to see if the G meter's internal transport protection screw has been fully wound OUT (counter-clockwise).
It's under the slotted cover ('B' in the attached PDF file) on the back of the meter.
You need to make sure that it's snug up against the casing (and not free to rotate) otherwise it might impinge on the mechanism.
Bon courage!
Rob R.

Hi,
Easy to repair, the big screw rear the accelerometer
is to stock the gmeter, the 3 screws are for SET the alarm
limit. Open completely the gmeter by the screws on the side
and you Will understand the mechanism it's easy
After the most difficult is to calibrate, I used for this my iPhone

thank you for your answer.
How do you use the iphone to calibrate it? I know that the iphone contains some accelerometer but I didn't know that you could access to the G values?

You can find it in AppStore, anyway attache
Your gmeter with you mobile,use for this adhesive
tape and move them with your hand and check
both value. A friend of me repaired my 2 gmeter
on my yak52 & now they work fine.

Yes if its worn so bad that it will not return to 1 g after a flight and gives erroneous measurements in the air, the rear cockpit G-meter is not wired to the aircraft and doesn't need the switch. But keep in mind that the Yak 52 G-meter has a switch in it, it is wired in front cockpit and front and rear meters are the same. I had to something with mine because the buzzer kept going off.
Does the GIB really need a G-meter?

Hi
I have a problem with my rear accelerometer on a yak52.
It shows on the ground a solid 2G instead 1G.
In the instruments back, there is 3 small screws and a big one.
Can somebody tells me how to set the instrument accurately?
Thanks

Hi all
There is a very basic, very easy G-meter calibration technique:
- Put the G-meter on a solid surface, in the normal flight attitude. It should now read 1G
- Stand it vertically upright. It should now read zero.
- Place it in the inverted position. It should now read -1G.
This technique is part of the overall calibration routine we use on G-meters fitted to some more modern aerobatic trainers, and is part of the OEM's documented procedure. The full procedure also includes checks on the effect of vibrations, but that is probably not done for the Russian G-meters.

Hi
Good news!
Thank you very much for all your advices, especialy Rob for the internal picture and Sam for the calibration procedure.
In fact, it was the transport screw that was blocking the Gmeter internal mouvement due certainly to the vibrations (good hoping so, Beach Boys forever  )) )
Bye and have nice flights
