Phase Sequence Indicators
Model: 72-3515

IMPORTANT SAFETY INFORMATION
• When using electrical appliances basic safety precautions should always be
followed.
• Wear personal protective equipment to avoid electric shocks and other injuries.
• Check whether the insulators of the test leads are damaged or have any exposed
metal. Inspect the continuity of the test leads. If any test lead is damaged, replace
it.
• Be very careful if the voltage is a true RMS of 30V AC, or 42V AC as peak, or 60V
DC because these voltages are always likely to cause electric shocks.
•When using a probe, place ngers away from its contact and behind the nger
protection device.
• The impedance generated by the transient current of the extra operating circuit
connected in parallel will possibly affect the measurement adversely.
• Before measuring a dangerous voltage, such as a true RMS of 30V AC, or 42V
AC, or 60V DC, make sure that the product is operating normally.
• Do not use any part of the product if it has been dismantled.
• Do not use the indicators close to explosive gases, steam or dust.
• Do not use in a humid environment.
•There are no user-serviceable parts in this product. Refer all servicing to qualied
personnel.
• When cleaning, do not use any chemicals, abrasives or solvents that may damage
the product.

MEASUREMENT DIRECTION OF THE ROTATING MAGNETIC FIELD
It is necessary to measure the direction of the rotating magnetic eld in the following
way:
• Insert terminals L1, L2 and L3 of the test pen into the L1, L2 and L3 holes
respectively.
• Insert the other terminal of the test pen into the alligator clip.
• Allow the alligator clip access to the phases of the three power cables to be
measured.
• Afterwards, the LCD will automatically display the sequence of L1, L2 and L3.
