6. Measuring methods

● Operations 3 phase rotation tester :
(1) Connect the test lead to 3-phase input terminals

by R-S-T.

(2) Connect color alligator clips to the terminals of

a 3-phase power source. Connecting order may
be optional.

(3) Make sure that all of the three lamps for open

phase check are on. If so, there is no open
phase. When any of the three lamps is not on,
there is open phase.

Open phase

“R”is not on

Open phase

"S" is not on

Open phase

(or BLACK) alligator
clip is connected

Open phase on
terminal where WHITE
(or RED) alligator clip is
connected

Open phase on terminal
where BLUE alligator
clip is connected

(4) Check the rotating direction of the rotation

indicator.
If lamp of counter clockwise is lit, alternate the
connection of the two of the three alligator clips.
If lamp of clockwise is lit, phase sequence is R,
S, and T in order of the power source terminals
where the RED (or BLACK), WHITE (or RED)
and BLUE alligator clips are connected.

7. Maintenance

● Fuse Replacement :
(1) It is necessary to replace fuse, when lamp

indicator R or T show no connection, and
Change R-S-T is the same.

(2) Use a screwdriver to unscrew the screws on

the back then open the case(Fig.2), take out
the broken fuse and replace with new fuse
(500mA/500V 5x20mm).

(3) Reinstall the case.
