Specification
1.
Open phase check by LED:       3 orange LED, show U Phase, V Phase, and W Phase respectively.
2
．
Phase order check through LED:   A red LED and a green LED
3.  Band:  Hitch on wrist to avoid the meter falling.
4.  Meter-pen
5.  Measuring Lead: red pen is corresponding U Phase (L1, R);
black is corresponding V Phase (L2, S);
blue is corresponding W Phase (L3, T)
Ⅳ
Operation method:
Be connected meter-pen and measuring wire together (Do not use hand directly). Any part of measuring wire is well (When measure in its middle part, shuck off its insulter and prevent get an electric shock. through measuring shelf is inserted in to metal explore nob and screw down, measurement become more convenience for customers). At that time, meter will show the phase and phase order.

Ⅴ
Reminds:
1. The meter is high voltage equipment, so check-up before use it. If there is appear follow cases, stop measuring to repairing:
A. Appearance scathe.
B. Extrusion in transit.
C. Store in wet places for long time.
2. Do not open the cover of meter when measuring.
3. Do not use hand to touch the metal of bareness thrum and meter-pen directly.
4. Prevent to get an electric shock when all light off, however, there is loop.
5. It is better to circuit voltage no more than 600V.
6. Time limit for continuous measurement 60 minutes at 200V AC and 4 minutes at 600V AC.
7. Do not use it in open air or other wet places.
8. Do not let it touch water or other liquid or directly to the sun.
9. Only professors can open its cover.
10. Users should take in special train and know well relatively knowledge and operate as this manual.
11. Put this manual under reach.
