## how often we should set a new test value
## A % 360 means 3600 seconds as we are on 10 second scan link
## A = 360 means 3600 seconds as we are on 10 second scan link
## Changing value is only a check in case it got saved into galil
## firmware so changing this once per ioc run is fine
## make sure we don't set a new value too soon
