PUSH-BUTTON POLARITY REVERSAL
Our Model 360 Ground Finder is a stand-alone tool designed to simplify, expedite and
standardize the testing for grounds required by FRA Rules No. 234.249 and 236.107. Testing
voltage is 22.5 VDC in both Test and Confirm modes, reflecting a standard common with
several railroads, avoiding "masking" below 20VDC, and out of normal signaling voltage
ranges. Unique “touch and go” operation greatly accelerates testing. And, with the 360 tester
it is not necessary to switch polarities to detect both positive and negative grounds where
circuit voltage is 16VDC, or less. For circuit voltages in excess of 16VDC, it will be necessary
