Phase Rotation Testers


480 Series Image
  • LCD Display
  • Operated Up To 690 Volts
  • Open Phase, Orientation, and Direction Check
  • Frequency Range 45~70 Hertz
  • Extremely Simple To Use
Phase sequence testing is a crucial step in connecting a three-phase load to an electrical system. For example, improper connection of three-phase motors may lead to reverse rotation, resulting in damage to equipment powered by the motor. Extech testers can be used to assure proper and safe connection of electrical equipment on three-phase systems.
PMR Series Image

  • Operated Up To 600 Volts
  • Open Phase, Orientation, and Direction Check
  • Frequency Range 45~70 Hertz
  • Extremely Simple To Use
Phase sequence testing is crucial for some of the three-phase loads, whenever they need to be connected to the electrical system. Improper connection of three-phase motors may lead to reverse rotation, and as a result it may damage equipment powered by a motor. Amprobes Testers are used to assure proper and safe connection of the electrical equipment on three phase systems.

PRM-6 Series Image
  • Indicates Motor Rotation of Disconnected Motors When Spinning the Shaft by Hand or Other Means
  • Error Displays (Missing Phase, One Input Connected to Neutral, or PE)
  • Non-Contact, Wireless Motor Rotation Detection on Running Motors
  • Durable, Rubber Casing for 3 ft. (1 M) Drop-Proof Protection
  • Synchronous or Asynchronous Motor Rotation Direction
  • Clear Backlit LCD Display with Easy to Read Symbols
  • 3-Phase to Phase Voltage up to 700 V
  • 3-Phase Wire Sequence Indication
  • Safety: CAT IV 600 V
The PRM-6 Phase Sequence and Motor Rotation Tester can test the motor rotation of 3-phase systems and verify 3-phase receptacle wiring and phase sequencing with test leads. An additional advanced feature is wireless motor rotation detection, which senses motor rotation direction without use of test leads, particularly useful for fast-running motors when the motor rotation cannot be visually determined or when the drive shaft is not visible. The PRM-6 is an essential tool for motor rotation and phase sequence testing in commercial and industrial environments on electrical systems up to 700 V.
480403 Series Image
  • Indicates Rotation Direction of the Motor
  • Determine Rotation of a Motor without Contact
  • Ensures that Motor does not Get Damaged from Incorrect Wiring
  • 40 to 600VAC Rated Test Range for Testing Phase Orientation of Three Phase Power Sources over 2 to 400Hz Frequency Range
  • LEDs Indicate Phase Orientation (Clockwise or Counter-Clockwise) and whether Each of the Three Phases is Live
  • Durable Housing is Double Molded
  • Easy to Open Alligator Clips with Wide Jaws
  • Complete with Cable and Three Large Color Coded Alligator Clips, Pouch Case, and 9V Battery
MOTOR PHASE METERS Series Image
  • Safety Ratings, CAT III, CE, CAT IV
  • Line Powered
  • LCD Display
  • Open Phase, Phase Orientation, Direction Check
  • Up To 690 Volts
A rotation tester consists of the combination of the 3-phase rotation tester with a motor rotation tester. The motor rotation tester measures the direction of motor shafts, and ensures the motor is not damaged from incorrect wiring. The 3-phase tester tests phase orientation of three phase power sources. Indicates (clockwise or counter-clockwise) orientation, and whether each of the three phases is live. Usually the cables on the meter are color coded, to indicate each individual line.
