Features & Applications
• Determine phase relationships and approximate
voltage, line-to-line or line-to-ground
• Feature two fiberglass poles with end fittings threaded
for interchangeable probes
• Probe fittings couple with a high-impedance
component encased in each pole
• To complete test circuit, a 22 ft. length of insulated
flexible cable stores on reel affixed to one pole and
connects to voltmeter on other pole
• Simple to operate, tester poles first attach to two 6 ft.
Epoxiglas
®
insulating universal handles (included in
each kit for proper working clearances)
• Probes can be brought into contact with conductors
appropriate for the meter to read phase-to-phase or
phase-to-ground voltage
Single-Range Units
• For convenience on different systems, toggle
on dual-range units can switch calibration
between two scales on meter face
• Can improve readability for low-end values on
Hi scale
• Switched to Lo range, those values deflect
needle more to give more finite readings
• To check instrument before and after each use,
test-point jack in front of meter accepts plug
from Phasing Meter Tester, next page
For URD testing, see Hi-Pot
Adapters (page 2458) and
Adapters for Elbows and
Bushings (page 2467).
