Soak Test
Use the Soak Test function to continuously measure
the non-compensated resistance tip to ground and
ring to ground simultaneously.
Press the [Right] arrow key to access the Soak test
from the Resistance screen. Connect the red and
black leads to an inactive pair. Connect green to
shield or ground. Use the [Right] arrow key to
refresh the measured resistance to the “Snap Shot”
area. This measurement will not be accurate if
there is foreign voltage or battery cross on the line.
