4. MEASURING METHODS
(1)Connect color coded alligator clips to the terminals of a
3-phase power source where a rotating electrical
machine, such as a motor will be connected.
Connecting order may be optional.
(2)Press the pushbutton switch located on top of the unit.
Keep this button pressed during phase sequence or
open phase check. When the pushbutton switch is
released, it immediately goes off.
(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 check
lamp "R" is not on
Open phase on terminal where
RED alligator clip is connected
Open phase check
lamp "S" is not on
Open phase check
lamp "T" is not on
Open phase on terminal where
YELLOW alligator clip is connected
Open phase on terminal where
BLUE alligator clip is connected
¶ When the open phase check lamps are not on, the
rotating disc does not turn.
(4)Check the rotating direction of the inside disc through
the phase sequence indication window.
l When the rotating disc turns counter-clockwise,
alternate the connection of the two of the three alligator
clips, then the rotating disc will turn clockwise.
l When the rotating disc turns clockwise, phase
sequence is R, S and T in order of the power source
terminals where the RED, YELLOW and BLUE alligator
clips are connected.
