The old method for testing large banks of 8‐ and 11‐pin relays involved removing the plastic cover of each relay to be tested, clipping meter test leads to the appropriate pins, and then pushing the moving portion of the relay to close one set of contacts. However, with an analyzer, this method became unnecessary, and the time required for testing was reduced from minutes to seconds. The article lists materials and instructions for construction of the analyzer.
