New Mistral Keypad Test System released. Mistral is the
successor to our popular Stingray Keypad Test System. We've
significantly increased testing speed
and doubled the resistance measurement range.
The biggest improvement though is in how we handle LED testing. You can now
specify LED's just like the manufacturers do, with forward
voltage and reverse leakage current. view

Stingray V2.1.0 software is now available. This version includes
two major new features you've been asking for. First, we've added
support for switches that connect more than two pins when pressed
("multi-pole" switches). After each path for the switch has been
specified by a switch item, you can now group the items together and
they will be treated as a single switch when testing. We've also
added the ability to specify the forward voltage for each of the
LED's on your keypad. The voltage measured during testing must be
within the allowable range for the LED to be considered good. view
