[Amps] Relay Timing Measurements

["KG8YN" <kg8yn@neo.rr.com>]

If you use a scope, unless it is storage, you need to see it many times, and 
read the graticule carefully.

I use a dual channel counter timer.  Put it in the Time A-B mode. Set for 
manual trigger, but not too close to zero.  Set the range for a resolution of 
.1ms.  Put a battery in the contact circuit.  The coil circuit starts the 
timer, the contact circuit stops the timer.  Read the value directly, and add a 
typical amount of time for contact bounce depending on the size and inertia of 
the relay.
