STEP 7. TURNING ON THE UNIT FOR HOLIDAY DETECTION.
Turn the unit clockwise to the ON position. In this position the unit is in
the normal running mode with the red indicator LED on steady, the horn
tone will be steady, and the display will turn off.
NOTE: Voltage setting can only be viewed in the middle set position.
This is to prevent confusion during detection of holidays as the voltage will
drop when the unit discharges to substrate. Static electricity on protective
coatings can be picked up and can cause fluctuations in Voltage reading.

IMPORTANT: In the field, setting the Inspection Voltage must be
performed with the detector wand disconnected from the spring/pipe.
The main reason for this is the potential buildup of static electricity/
static voltage on the surface of the pipe coating. The detector’s internal
voltmeter is very sensitive and responds to any static voltage. The static
voltage typically fluctuates up and down which can be confusing when
setting the Inspection Voltage. To remove this uncertainty always adjust
the voltage with the detector disconnected from the spring or pipe.
