The OhmstikPlus Live-Line Micro Ohmmeter measures the micro-ohm resistance of conductors, connectors, splices and switching devices positioned directly on an energized, high voltage lines.
The OhmstikPlus calculates resistance by measuring the AC amperage in the line and the voltage drop due to the resistance of the line segment under test.
Using the AC current in the line ensures that realistic current distributions through the connection are being measured. The instrument is pressed against the splice or connector in such a manner that the connection under test is between the two electrodes.
In a few seconds the instrument is removed from the line and the line amperage and resistance are displayed on the front panel LCD.

Designed to store up to nine sets of readings. The ability to hold the multiple readings ends the need to raise and lower the hot stick after each measurement.
This measurement is much more direct than infrared thermography, and is not subject to emmissivity, weather, current loading, background, and other influences that cause infrared errors.
