  • Testing of relays and similar devices
    Patent number: 4319193
    Abstract: Relays and similar devices are tested by applying electric power to the coil to actuate the armature, measuring armature travel and comparing the measured travel to a datum to produce a percentage relationship. Datum values for the armature travel required to actuate each contact are connected by this produced percentage relationship to produce new datum values for each contact. The armature travel at actuation of each contact is measured and compared to the new or connected datum values. Output signals are desired for the actuation of each contact indicative of the relationship between actual actuation travel and the new datum values.
