Tracy,

I got my EM-2 back from you – Thanx – EGT’s are now starting at ambient temperature instead of 1800deg.  You included a note warning about possible ESD (electro-static discharge) damage. The suggestion you pointed to in the new EM-2 manual is to disconnect all the plugs from the EM-2 before connecting or disconnecting any sensor. I thought I’d open a public dialogue on this since it would be a major operation to open my instrument panel and disconnect the EM-2 every time I touch a sensor connection. It’s probably the same for many others.

 

Since I work around computers all-day everyday I’m aware of ESD. Would similar precautions used on computers be acceptable?  I.e. Make sure you are at the same potential as the airframe ground before touching any sensor connection? Alternatively, one end of a test lead alligator clip could be attached to the sensor connector and the other end attached to ground. This keeps loose, unconnected sensor wires from inadvertently being touched and becoming the path to ground.   

 

Are these acceptable alternatives to unplugging the EM-2?
