Stratologger SL100 and switch

[english_1969]

I'm wiring up a couple of stratologgers sl100 for my L3 rocket and in the process noticed that out of the box, the SL100s have a shunt installed on the switch terminals.

So, I wondering if I should:
a) Remove the shunt and wire my switch to the correct switch terminals, or

b) use the switch to break the circuit between the battery and the unit.

I would normally do (a), but now I just wondering if there is some benefit and thus the reason the shunt is installed. Maybe the benefit has to do with keeping the unit running through a power blip or a switch bounce. The manual states that the SL100 can withstand a short loss of power.

Any thoughts or advice on this?

I did RTFM and it's not clear to me.

I remove it, and just use an old e-match wire to run it to the outside of the rocket.
When ready: I just twist the leads together to close the circuit.

BTW: Great altimeter!

JD does the stratologger have the same mounting foot print as the hialt45?.

 

[JDcluster]

Not sure, as I've never owned a HiAlt45.
I do have the MAWD and it is different.

CHAD measuring tells me:
2.5" x 21/32" centers on drill holes

Unit is: 3.75" long x 7/8" wide.

Looks like they use the same mounting foot print. Good now I will replace all my hialt45s with the new SL100

Thanks JD

Scott, Yes they have the same mounting footprint and also the same lay out for the connections. I would get the data cord as well because using the computer program to set the SL100 is easer than doing it without. I have both the hialt45 and SL100. infact thats what I used for my L3 cert flight last year.

The jumper wire connected to the switch terminals is there to do a power up test by just connecting the battery.
The jumper is removed before you connect a switch or twisted pair, to complete the wiring circuit.

Yes, same exact footprint. I only use HiAlt45 and Stratologgers.... all my ebay are setup for these and they fit interchangeably.

 

[robbdm]

For my L3 I used one HiAlt45 and one Stratologger....

Back to the OP's question. If you are putting in a nice switch (rotary, screw, magnetic), then I would leave the shunt in the altimeter and wire the switch in the positive power lead to the battery. This makes things cleaner with fewer wires. It also eliminates one set of wires to undo/redo if you are moving the altimeter to another sled/rocket.

Buckeye: thanks for the advice. I couldn't wait and ended up wiring to the switch terminals. I agree with you that it would have been cleaner, but couldn't resist following the directions

Best thing to do is follow the manufactures instructions. Who better would know the product.
