See table 2 for the minimum motor diameter and number of pole pair to
obtain a reliable test result.
Table 2. Reliable Motor Test Requirements
Determine the Motor Connection
1.
Connect on end of the test leads to the motor and phase rotation meter.
Make sure the L1, L2 and L3 test leads are connected to the
corresponding jack.
2.
Connect the croc clamps to the other end of the test leads.
3.
Connect the croc clamps to the motor connections, L1 to U, L2 to V, L3
to W.
4.
Press the ON/OFF button. The green ON indicator shows that the
instrument is ready for testing.
5.
Turn the motor shaft half a revolution towards the right.
Note:
The bottom of the motor and phase rotation indicator should be oriented
towards the drive shaft. See the orientation symbol on the motor and phase
rotation meter. Either the clockwise or counter clockwise rotary indicator
illuminates showing the type of rotary field direction present.
Magnetic Field Detection
To detect a magnetic field, place the motor and phase rotation meter to a
solenoid valve. A magnetic field is present if either the clockwise or the
counter clockwise rotary indicator illuminates.
Note:
The motor and phase rotation meter contains alkaline batteries. Do not
dispose of these batteries with other solid waste. Used batteries should be
disposed of by a qualified recycler or hazardous materials handler.
