I am in need of a Hickok Model 531 (KS-13588-L1) operation manual, schematics and any other information for this device.  Are there any resources online that can be downloaded?  The tester I possess seems to be in good working order.  Some of the labeling is missing on the facing or no reference to where to plug in the Grid Test Lead. 

Thank You!
