Circuit and wiring issues listed above can introduce shock hazards (from grounding issues) and can comprise performance of machinery and equipment (from poor ground impedance, lack of sufficient voltage under load and/or high ground-to-neutral voltage). In addition, fire can result from the heat generated by high resistance points in a circuit.

Proper wiring habits have been shown to greatly increase power quality performance

The Extech 480403 phase sequence and motor rotation tester uses alligator clamps which can be used to check the phase rotation of a power supply and indicate whether each of the three phases are live or not. This will allow maintenance personnel to ensure that a motor being connected to the power supply will not be damaged or cause equipment damage by being started in the wrong direction.

The non-contact motor rotation feature of the Extech 480403 phase sequence and motor rotation tester allows the user to check the direction of motor rotation on a running motor by simply placing the meter in close proximity to the motor being checked with the same orientation as the easy-to-read schematic on the face of the meter. The rotation LEDs will then light up to indicate clockwise or counter clockwise rotation.

Can be used to determine the phase orientation of a three-phase power supply or the direction of rotation on a three-phase motor. The Extech 480403 phase sequence and motor rotation tester features a durable double molded housing and three large, wide jaw, colour-coded alligator clips, all with a CE CAT III-600V rating.

• 75 to 1000VAC input voltage with 45 to 65Hz frequency range
• LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each phase is live
• Beeper sounds intermittently when correct phase is detected and continuously if phase is reversed
• Durable housing with back cover magnet for attachment to an AC distribution panel for easy measurement
• Adjustable Hi/Lo LED brightness switch for making measurements in dimly lit areas or sunlight
• Fully insulated non-mettalic alligator clips with wide jaws that clip onto the insulated wire
• Low battery warning
• Complete with three built-in 30″ test leads with large color-coded alligator clips, four AA batteries, and pouch case

Brightness

Press the Brightness button to increase the light intensity of the LEDs. This can be helpful in observing the LEDs in brightly illuminated areas.

Auto Power Off

In order to extend battery life, the unit will automatically shut off after 5 minutes of inactivity.

Magnet Mounting

Four magnets are located on the rear panel to enable convenient hands free mounting during use.

The comparator function compares the measured values with pre-set High and Low limit values for internal resistance and voltage level, and determines the range that the measurement should fall into. Then, according to the following conditions, switches ON the corresponding LED, and sounds an audible alert as shown in the table below for the WARNING and FAIL conditions.
