Overview:MER Meters are faster and simpler to use when measuring direct current on steel pipe, near rebar, or a battery cable on a vehicle.The MER model Swain Meter is a 1 percent clamp-on DC ammeter for measuring actual line current and direction of flow during normal operation.
Accuracy is better when measuring a small current because zero offset error due to local magnets is reduced. Generally, the short two step Floating Zero procedure suffices.
Offshore platform anode current or transmission line current can be measured at 700 ft depth or more. MER clips (to 6in dia.) and clamps (to 60in dia.) work undersea for a long time when waterproof connectors are provided.
