MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT IC TERMINALS.

OFF ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NC TERMINAL.

ON LOSS IS MEASURED BETWEEN COM_ AND "ON" NC TERMINAL.

SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.

V- IS CONNECTED TO GND (0V) FOR SINGLE-SUPPLY OPERATION.
