Signametrics
Remarks
This function Cleans all relays. The test connector must be present to clean all contacts.
This function verifies that the test connector is present. Cleaning takes about 13 seconds.
Vibrating of the contacts at varying switching patterns, while sourcing a high voltage/low
current signal, causes deposits of contaminants as well as oxidations to bounce off or be
pinched through, thus resulting in cleaner contacts. Doing this on a regular basis will
prolong the contacts’ life. Both Channel relays and Configuration relays are cleaned.
Function type: Polled, requires SCANReady() prior to using additional functions.
