        4.  Check the rotating direction of the 

rotation indicator if:

Operating motor rotation tester:

        1.  Make sure there is no voltage present.

        2.  Connect the test lead to motor input 

terminal by L1 - L2 - L3, and press the 

power button (Fig 1). The power 

indicator green lamp is lit. (If red lamp of 
clockwise or counter clockwise is lit before 
rotating the motor shaft, it means there is 
voltage present. Please stop measuring, 
take off the test leads and turn off the 
external power). If red lamp is lit while 
rotating the motor shaft clockwise, it
 means 3-phase motor connection to the 
power supply by L1 - L2 - L3, the 3-phase 
motor will rotate clockwise.

        3.  Connect the lead to 3-phase motor by 

L1 - L2 - L3, and press the power button on. 

The power indicator green lamp is lit. 

Rotating the motor shaft counter clockwise. 
If red lamp of counter clockwise is lit. it 
means 3-phase motor connection to the 
power supply by L1 - L2 - L3, the 3-phase 
motor will rotate clockwise.

     

       4.  If you require the motor to rotate counter 

clockwise, you should change connection to 
L2 - L1 - L3, the motor should now rotate 
counter clockwise.

Maintenance

Battery Replacement:

        1.  It is necessary to replace battery, when 

green lamp is dull.

        2.  Use a screwdriver to unscrew the screws on

the back. Open the case (Fig. 2), take out the 

battery and replace with new battery type 
(DC 9V alkaline battery).

        3.  Reinstall the case.

Fuse Replacement:

        1.  It is necessary to replace the fuse when the

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. Open the case (Fig. 2), take out 

the damaged fuse and replace with a new 
fuse (200mA, 250V).

        3.  Reinstall the case.

Cleaning and Storage:

           

WARNING!

To avoid electrical shock or damage to the meter, 
do not get water inside the case. 

   

Periodically wipe the case with a damp cloth and 
detergent; do not use abrasives or solvents.

If the meter is not to be used for periods of 
longer than 60 days, remove the battery and 
store them separately.
