Use the Ampstik+ to safely take accurate current measurements when performing high voltage live-line load checks for balancing, switching, or breaking load.

This high voltage ammeter measures in every electric utility setting with a linear current sensor to accurately measure .5A to 5000A, while in voltage environments up to 500kV. The opening of the amp sensor is electronically closed, while external currents are electronically rejected. This design enables the user to measure an individual conductor within close proximity to adjacent conductors without interference errors.

The Ampstik+ holds up to four readings, ending the need to raise and lower the hot stick for each reading. Position the unit over the conductor and the meter will store the current measurement within 2 - 4 seconds. Move to the next conductor and repeat the process. Return the unit to eye level once all the measurements have been taken.

The backlight will automatically power on when the ambient light is low. This feature enables users to better view readings on the display in low-light situations.

The Ampstik+is easy to operate and gives accurate information for all users working with low, medium, and high voltage. This instrument provides correct answers, giving line personnel the confidence to make immediate decisions while working and troubleshooting in the field.
