Warning

Electric shock and fire hazard:

Do not expose this unit to rain or moisture.
Do not use the unit if it is wet or damaged.
Test leads or any other accessory, when used to make a measurement, create a System.
The System is rated for CAT III 600 V or CAT IV 300 V when using the test leads or accessories provided with the meter. The System CAT and voltage rating is limited by the lowest rated component in the System when using test leads or accessories not provided with the meter.
Inspect the test leads or accessory before use.
They must be clean and dry, and the insulation must be in good condition. Do not use the test lead if the contrasting inner layer of insulation is visible.
Use this unit for the manufacturer’s intended purpose only, as described in this manual. Any other use can impair the protection provided by the unit.

Failure to observe these warnings could result in severe injury or death.

Warning

Electric shock hazard:

Do not apply more than the rated voltage between any two input terminals, or between any input terminal and earth ground.
Keep hands and fingers below the barriers on the test leads.
Failure to observe these warnings could result in severe injury or death.

Warning

Electric shock hazard:

Do not operate with the case open.
Before opening the case, remove the test leads from the circuit and shut off the unit.

Failure to observe these warnings could result in severe injury or death.

Warning

Electric shock hazard:

Unless measuring voltage, shut off and lock out power. Make sure that all capacitors are discharged. Voltage must not be present.

Failure to observe these warnings could result in severe injury or death.

Caution

Electric shock hazard:

Do not attempt to repair this unit. It contains no user-serviceable parts.
Do not expose the unit to extremes in temperature or high humidity. Refer to “Specifications.”
Failure to observe these precautions may result in injury and can damage the unit.

Warning

Electric shock and fire hazard:

Do not connect the unit to 500V or greater for longer than 10 minutes.
If the unit has been connected to 500V or greater for 10 minutes, disconnect the unit for at least 10 minutes before using again.

Failure to observe these warnings could result in severe injury or death.

Operation

Determining Phase Sequence (Contact Type)

Insert the test leads (L1, L2, L3) into the corresponding input terminals of the 5124 (R, S, T respectively) and then to the alligator clips.
Connect the alligator clips in L1, L2, and L3 order to the three phases of the system.
Press down the “ON” button and the 5124 power indicator will illuminate. Press and hold the “ON” button to conduct the test. During the test, the “Clockwise” (R) or “Counter Clockwise” (L) rotation indicator will illuminate to indicate whether the system is under a “Positive” or “Negative” phase sequence.

Checking Rotary Field (Motor Rotation, Non-Contact Type)

Remove all test leads from the 5124.
Place the 5124 towards the motor, in parallel with motor shaft. The bottom of the instrument should face the shaft. The 5124 should be oriented such that it is opposite the front of the motor as shown in Figure 2. The motor location indicator is also shown on Figure 1.
Press the “ON” button and the power indicator will illuminate and the test will begin. While the motor is running, the “Clockwise” (R) or “Counter clockwise” (L) will illuminate indicating the direction of rotation of the motor.

R LED indicator is on when the motor rotates clockwise

Note: This non-contact test is applicable for both single-phase and three- phase motors. The instrument will be unable to indicate accurately with motors controlled by a frequency converter.

Detecting Magnetic Field
Place the 5124 into a location with suspected magnetic field. If either the “Clockwise” (R) or “Counter clockwise” (L) indicators illuminate while the “ON” button is pressed, then magnetic field exists in the location.

Maintenance

Warning

To prevent damage to the 5124:
Repair or maintenance of the 5124 should only be performed by Greenlee authorized technicians.
Do not use corrosive or solution since those substances will cause damage to the chassis of the 5124.
Prior to cleaning, remove all test leads from the 5124.

Warning

Electric shock hazard:
To prevent electric shock, it is necessary to remove all testing leads from the 5124 prior to replacing the battery. The 5124 contains a 9V/6F22 battery, do not discard the battery with other solid wastes. The used battery should be disposed of properly in accordance with local government regulations.

Replacing the Batteries

Remove all testing leads from the 5124.
Take off the protective casing.
Place the 5124 face down on a non-abrasive surface and unscrew the battery cover.
Remove the battery cover and remove the battery after loosening the battery buckle.
Replace the battery as shown in Figure 3.
Ensure that the battery polarity is correct.
Reinstall the battery cover with screws.
Put the protective casing back over the 5124.
