1. Preface
Thank you for buying our excellent product.
Products available on the market are not
very user-friendly: their test AC phase and
motor phase are separated from each other,
have two sockets (to be plugged out before
use), etc. When you use the you will not
have these troubles anymore, and time is
saved. So enjoy it !
2. Application
Test for poles of the 3-phase power
source, L1/A, L2/B and L3/C, and identify
which phase for which wire.
Determine the 3-phase motor’s direction
of rotation (clockwise or
counterclockwise) and the circuit status
of the motor wires.

3. Features:
In each test, Push “ ” button turn on
the meter, push “ ”button again to turn
off the meter. or auto shut off after 15
minutes ( TM-601N)
Check the 3 wires of the power cord, L1,
L2 and L3 through the 3 red lamps, which
indicate if each wire is connected well.
Check if L1, L2 and L3 are in place, the 3
motor wires, the motor’s direction of
rotation, and the ER red/green OK
indicators.
When the battery is low, an indicator will
turn ON to remind you to replace it.
hold the power button and check the
panel indicator. (TM-603/604)

5. How to operate
5.1. How to test the 3 phases of AC
Let your crocodile clip clamp the 3-phase
power terminal. In each test, hold the power
button and check the indicators on the panel.
If L1, L2 and L3 are lit, it means normal.
(In this case, skip to step 2.) If one of
them remains unlit, L1 for example, it
means the wire for L1 is disconnected or
in power failure mode. You may check
visually or with a multimeter if the wire is
connected well.
Next, check if the red or green lamp is lit.
If it is the green lamp, it suggests L1, L2
and L3 are correct for their phases. (In
this case, skip to step 6). If it is the ER
red lamp, it means L1, L2 and L3 are
wired incorrectly. You must correct them
before proceeding to step 3.
Exchange L2 and L3. If the green lamp
goes ON, it means the 3 phases are
correct. (In this case, skip to step 6.) If
the red lamp ER goes ON, it means the 3
phases are wired incorrectly. You must

TM-601N/603/604
EN-5
correct them before going to the next
step.
Exchange L1 and L3. If the green lamp
goes ON, it means the 3 phases are
correct. (In this case, skip to step 6.) If
the red lamp ER goes ON, it means the 3
phases are wired incorrectly. You must
correct them before going to the next
step.
Exchange L1 and L2. If the green lamp
goes ON, it means the 3 phases are
correct. (In this case, skip to step 6.)
Note the definition for L1, L2 and L3
each.
5.2. How to test the motor’s
direction of rotation
Make sure the motor’s power source has
been removed.
Connect the test wire to the motor
terminal. In each test, press the power
button, then check the indicators on the
panel: when the motor is not turning, the
red lamp is ON.
The green lamp goes ON when the motor

TM-601N/603/604
EN-6
turns clockwise, and the red lamp goes
ON when it turns counterclockwise.
(Normal; skip to step 8.) If the motor turns
clockwise and counterclockwise and the
red lamp remains ON (the red and green
lamps do not go ON alternately), this
suggests one wire is disconnected or not
connected well. Please measure the
motor’s 3 wires with a multimeter and
check if there is a disconnection between
any 2 wires. (If the motor is disconnected,
change it.)
The green lamp goes ON when the motor
turns clockwise, and the red lamp turns
ON when it turns counterclockwise. This
suggests the wiring of L1, L2 and L3 is
normal. (In this case, skip to step 8.) If
the red lamp goes ON when the motor
turns clockwise, and the green lamp goes
ON when it turns counterclockwise, this
indicates that the wiring sequence must
be corrected. Go to step 5.
Exchange L2 and L3. The green lamp
goes ON when the motor turns clockwise,

TM-601N/603/604
EN-7
and the red lamp goes ON when it turns
counterclockwise, this suggests the
wiring of L1, L2 and L3 is normal. (In this
case, skip to step 8.) If the red lamp goes
ON when the motor turns clockwise, and
the green lamp goes ON when it turns
counterclockwise, this indicates the
wiring sequence must be corrected. Go
to step 6.
Exchange L1 and L3. If the green lamp
goes ON when the motor turns clockwise,
and the red lamp goes ON when it turns
counterclockwise, skip to step 8. If the
red lamp goes ON when the motor turns
clockwise, and the green lamp goes ON
when it turns counterclockwise, this
indicates the wiring sequence must be
corrected. Go to step 7.
Exchange L1 and L2. If the green lamp
goes ON when the motor turns clockwise,
and the red lamp goes ON when it turns
counterclockwise, this suggests the
wiring of L1, L2 and L3 is normal. (In this
case, skip to step 8.)

TM-601N/603/604
EN-8
Once the green lamp goes ON when the
motor turns clockwise, and the red lamp
goes ON when it turns counterclockwise,
the 3 phases are correct. Then the
motor’s R.S.T. can be connected to the
power system’s L1, L2 and L3. Now your
motor can run correctly.
