This timer can be used for ignition of sustainer motors in multistage rockets and
ignition of air-started auxiliary motors. It can also be used for accurately timed
deployment of recovery devices in lieu of the sometimes variable delay times associated
with the motor's built-in delay grain. Delay time can be set with 0.1 second resolution
via an on-board pushbutton.
The miniTimer3G includes a built-in G switch trigger for automatically initiating
the delay on launch. The only external items necessary are a battery, igniter, and
on/off switch. Igniter continuity is reported via a built-in beeper, which doubles
as a post-flight locator siren.
The miniTimer3’s extremely high current capability allows the use of virtually any
igniter type, as well as multi-igniter clusters. When powered by a suitable battery,
firing 50 ematches simultaneously is possible!
