Grounding
Ensure the ground (earth) cable is uncoiled and fully extended.
Connect the ground clip to an exposed (uncoated) area of the part,
or grounding rod. If no ground is available, a trailing ground wire,
grounding collar, or grounding mat may be used. Verify that the
instrument is properly grounded by touching the electrode to the
grounded substrate, ensuring that the audible and visual alerts are
properly triggered.
Never touch the ground cable while the detector is operating.
WARNING:
Operational Check
Prior to each use, the
PosiTest HHD
should be checked to ensure
it is operating correctly. This operational check ensures that the
audible and visual alerts are operating properly and the instrument
has voltage output. For
Calibration and Verification
see pg. 10.
Performing an Operational Check
1. Ensure the instrument and all components are assembled.
2. Visually inspect each cable and connection.
3. Press and release the power button on the top of the
PosiTest HHD
.
4. The
PosiTest HHD
should power on and display the test
voltage.
5. Press and hold the button and then activate and hold the
safety trigger on the
PosiTest HHD
to turn on the high voltage
and activate
Detection Mode
. The button can now be
released.
6.The
PosiTest HHD
should begin testing at the selected voltage.
The display will show the voltage being generated.
7.Touch the electrode to the bare ground wire or grounded
substrate of the part being inspected. Note the audible and
visual alerts. Repeat this step several times.
A spark may or may not be seen and heard. When
using a lower test voltage and on bright sunny days, the spark
may not be seen or heard.
