Motor shaft rotation direction (connectionless)
Press
to turn the tester on. The green diode should go ON
signalling that the device is ready for operation.
Put the rear part of the TKF-13 tester to a working motor along its
axis (the position of the axis in accordance with the adjacent illus-
tration). The distance between the tester and the motor should not
exceed 2-3 cm.
The light of the R diode means the motor shaft spins clockwise.
The light of the L diode means the motor shaft spins anticlock-
wise.
Lack of indications (diodes L and R are off) may mean the motor
is not working or the signal is too weak.
In case of certain single-phase inductive motors, indica-
tions may be hindered.
The device has not been designed for the purpose of
tests of single-phase commutator motors.
The device has not been designed for the purpose of
tests of motors powered through electronic power con-
verters (inverters).
Below there is a diagram illustrating the minimum motor diameter for the given revolution and the fre-
quency of the mains at which the indications of the tester are reliable.
