DVM-80T
DESCRIPTION
Our extensive line of voltmeters and phasing sets are designed to measure AC and DC voltages on conductors from
phase-to-ground and phase-to-phase. These instruments also
allow the user to determine if two conductors are
in-phase or out-of-phase with one another. There are numerous
models available with different ranges to assure the best possible range for easy readings. All models are designed for
use on overhead lines and are adaptable for use on underground systems by using accessory probes.
Our analog line of voltmeters and phasing sets include
the MARK
phasing sets include the DigiVolt
and phasing sets feature universal splines for mounting onto
hotsticks and large easy-to-read displays.

in Metal Enclosed
Switch Gear
• Determine whether a
section of underground
cable is faulted with
the Cable Fault Tester
(optional accessory)
• Discharge underground
cables and other equipment
that hold capacitive charges

MARK®& EM ANALOG FEATURES
There are three models of the EM series voltmeters and eleven models of the
MARK series voltmeters and phasing sets. The EM series are all single stick
voltmeters with one resistive probe with universal spline and ground lead, for
phase-to-ground measurements only. The MARK series are all dual stick
phasing voltmeters with connecting cord and universal spline for
phase-to-phase and phase-to-ground measurements.
• Coil cord is standard on all MARK and EM series
products. Coil cord is rated at 10kV. Length
is 3.5’ (1.7m) retracted and 12’ (3.6m) fully
extended. Optional lengths are available.
Optional reel with straight cord
available at no additional cost in
lengths up to 22’ (6.7m). Straight
cord is rated at 15kV.
• Accuracy 3% of full scale
• Universal splines
• Rugged construction designed for heavy field use
• Overhead brass hook contact probes
• Large 3” (7.6 cm) meter face with a Lexan protective cover is specially
designed for easy reading and increased accuracy. Multiple scales assist
the user in avoiding misreads.
• Strain relief fittings at ends of cords reduce cable damage at point of highest stress
• All fiberglass is quality tested to ASTM F-711 and OSHA standards
(100kV/foot for 5 minutes)
• High voltage resistors are encapsulated in epoxy in all resistor sticks, thereby
limiting maximum current to approximately 1 milliamp at full rated voltage.
• Virtually maintenance free - no batteries required
• Measures DC through 1000Hz AC RMS
