HDE, MARK-I-S, Dual Stick Voltmeter, Single Range, 0-15kV; Includes (2) 025-OLPS-5 and CM-100/V CaseOur 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. 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® and EM series. Our digital line of voltmeters and phasing sets include the DigiVolt ® series. All of the voltmeters and phasing sets feature universal splines for mounting onto hot sticks and large easy-to-read displays.FeaturesMeasure voltages from phase-to-ground and phase-to-phase up to 80kVDetermine if two conductors are in-phase or out-of-phaseMeasure voltages and phase conductors on both overhead and underground systemsVerify a conductor is de-energized prior to groundingMeasure voltages in Metal Enclosed Switch GearDischarge underground cables and other equipment that hold capacitive chargesAccuracy 3% of full scaleUniversal splinesRugged construction designed for heavy field useOverhead brass hook contact probesLarge 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 stressAll 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 requiredMeasures DC through 1000 Hz RMS AC.
