1. Introduction
PHS-864 Phase Detecor breaks through the traditional method for phase sequence detecting. In
traditional phase sequence detection, the wiring terminal of the three-phase must be peeled off
and connected the three exposed clips or test probes of the phase sequence meter to the three
exposed live wires. However, PHS-864 adopts the clamp non-contact induction measurement, no
need to peel off the wires or contact the exposed high-voltage live wire, the phase sequence can be
detected by directly clamping on the insulation outer skin of the three-phase live wire with three

super inductive high insulation clamps, while audible and visual indicators signify the positive or
anti-phase state of the three-phase power phase sequence. Four piece powerful magnets are
attached to the back of the meter, which can be attached to the distribution box for use.
PHS-864 Phase Detecor has the functions of live line detection, simple power electricity detect,
break circuit searching, break point location, lines maintenance and so on.
PHS-864 Phase Detecor is quick and convenient, the display is clear and obvious, it has greatly
improved the field test security, effectively protecting the operators personal safety, while also
increasing productivity! It is a safety standard instrument for three-phase power supply phase
sequence, motor detection and line maintenance.

Danger! High voltage! Please pay attention to safety!
6.1.1 Connection: Clamping on three phase wires respectively with the three clamps (Shown in
Fig-1).
6.1.2 The detected wire at the clamp with mark “ ” (Shown in Fig-2).
Fig-1 Fig-2
6.1.3 Press the red color “ON” startup key, the power indicator lamp will light up. If the power
lamp does not light up, this will indicate either a low battery or a damaged instrument, in
which case you will need to replace the battery or send it for repair.
6.1.4 After starting up, if the four phase sequence indicators light up clockwise, and the instrument
makes intermittent short chirps, then the clamped phase line is positive phase sequence L1-
L2-L3 (U-V-W) (Figure 1). If the four phase sequence indicators light up counterclockwise,
and the instrument makes a continuous sound, then the clamped phase line is in the reverse
phase sequence L3-L2-L1. (W-V-U) (Figure 2).

6.1.6 Press white color “OFF” key to shut down, the instrument will automatically shut down after
about 5 minutes without any operation to reduce battery consumption.
b. Live wire inspection, simple electricity detection.
Danger! High voltage! Please pay attention to safety!
6.2.1 Use any clamps to clamp on the tested wire. If the conductor has electricity (within the
setting range of live line voltage, AC70 ~ 1000V), the lamp of L1/U, L2/V or L3/W will light
up.
6.2.2 Clamps and lamps corresponding sheet:
Clamp Mark
Lamp light up symbol
L1/U (Red)
L1/U lamp light up
L2/V (White)
L2/V lamp light up
L3/W (Blue)
L3/W lamp light up
c. Default phase judgment, open circuit searching, breakpoints location.
Danger! High voltage! Please pay attention to safety!
6.3.1 Use any clamp to clamp on the three-phase line separately. If it is default phase, the lamp
L1, L2 or L3 will not light up.

7. Battery Replacement
Pay attention to the battery polarity!
7.1. Before replacing the battery, the clamp must be removed from the tested wire. Do not
replace the battery during the test.
7.2. Press “OFF” key to shut down. (Figure A)
7.3. Loosen the screw on the back of instrument and remove the battery cover (Figure B).
7.4. Replace the new batteries, pay attention to the battery polarity and specifications (Figure C).
7.5. Close the battery cover and tighten the screws (Figure D).
7.6. Press “ON” key and check whether the instrument can be started normally. If it cannot be
started, please check whether the battery power is enough or operate again according to
