The Ampstik Plus uses the same current technology that was developed for the original SensorLink Ampstik. The key feature of the Ampstik Plus is the ability to hold up to four True RMS amperage readings, ending the need to raise and lower the hotstick for each reading. The opening of the current sensor is electronically closed, while external currents are electronically rejected. This sensor design enables the user to measure an individual conductor within close proximity to adjacent current carrying conductors. The SensorLink patented amp sensor is not position sensitive; just slip the Ampstik Plus over the conductor.

The meter will store the current measurement within two seconds. Move to the next conductor and repeat the process. Return the instrument to eye level when all four of the measurements have been completed. This easy storing and retrieval of data makes the Ampstik Plus a practical and labor saving instrument. One meter is all that the user will require. The Ampstik Plus measures in every electric utility setting. Its linear current sensors accurately measure loads from 1 amp to 5000 amps, as well accurately measures in low to high voltage environments of up to 500kv. The universal hot stick adaptor and internal structure of the Ampstik Plus are made of long glass fiber reinforced thermoplastic polyurethane called Celstran.
