We appreciate your having purchased our phase sequence and

motor rotation direction tester. The TKF-13 tester is a modern high-

quality, simple and safe device. However it is recommended to get

acquainted with the present manual in order to avoid measuring

errors and prevent possible problems related to operation of the

meter.

Note:

The producer reserves the right to modify the appearance,

equipment and technical data of the device.

1. Safety measures

The TKF-13 tester complies with the safety requirements

specified in the norm EN 61010-1.

In order to protect yourself and the device do observe the rules

described in the present manual.

Warning:

•Do not perform tests in a humid environment, which contains

explosive or inflammable gases (materials), water vapour or

dust.

•Having carried the device from a cold environment to a warm

one, wait 0.5 hour before you proceed to perform

measurements for the purpose of acclimatisation, if necessary

wipe out the condensed water vapour.

•During measurements do not touch the metal parts of the

socket, lead terminals, fastening elements, circuits, etc.

•Make sure you are properly insulated from the tested object.

•Do not perform measurements using an out-of-order device,

whose casing or leads are damaged (broken, cracked,

deformed, contaminated, etc.).

•The TKF-13 tester may be operated exclusively by qualified

personnel who are properly authorised to perform work on

electric installations. Should the device be operated by

unauthorised personnel, the device may be damaged and

there may be a serious danger for the operator.

•The tester may be connected to the mains solely by means of

dedicated leads provided by the manufacturer. Solely such

leads guarantee compliance with safety regulations.

•If phase-to-phase voltage exceeding 760V AC will be

connected to the device, the tester may be damaged and there

may be a risk for the operator.

•If the device will be used for any other purpose than those

specified in the present operating manual, the tester may be

damaged and there may be a serious risk for the operator.

2. Phase spin direction test

•Press to turn the tester on. The green diode should go

ON signalling that the device is ready for operation.

•Connect measurement probes to the TKF-13 tester.

•Connect measurement probes to the points where there is the

expected three-phase voltage (see the illustration below).

•If the phases at the given

measurement points are

compliant with the L1, L2, L3

description, the R diode of the

tester will go on; otherwise

the L diode will go on.

•The light of the given neon

lamp (L1, L2, L3) signalises a

voltage exceeding 100V

between the corresponding

probe and one of the

remaining probes.

Note: Incorrect

indications of

the tester may

be caused by

one of the

following:

- connection of

two probes to one phase,

- connection of one of the probes to the neutral

lead,

- lack of connection of one of the probes to the

mains.

3. Motor shaft spin direction (using

leads).

•Disconnect the motor from the mains.

•Press to turn the tester on. The

green diode should go ON signalling that

the device is ready for operation.

•Connect measurement probes to the TKF-

13 tester.

•Connect measurement probes to the

tested motor (see the adjacent illustration).

•Rotate the motor shaft energetically in the desired direction.

•The light of the R diode means the connection to the U, V and

W motor terminals of phases L1, L2 and L3, respectively, will

cause rotation of the motor in the direction the shaft spun

during the test.

•The light of the L diode means the connection to the U, V and

W motor terminals of phases L1, L2 and L3, respectively, will

cause rotation of the motor in the opposite direction to the

direction the shaft spun during the test.

•Make sure the shaft rotates in the desired direction once the

motor has been connected to the power supply source

performing a phase sequence test (see Chapter 2).

4. Motor shaft spin 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

illustration). The distance between

the tester and the motor should not

exceed 2-3cm.

•The light of the R diode means the

motor shaft spins clockwise. The

light of the L diode means the

motor shaft spins anticlockwise.

•Lack of indications (diodes L and R

are off) may mean the motor is not working or the signal is too

weak.

Note:

•In case of certain single-phase inductive motors, indications

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 converters

(inverters).

Below there is a diagram illustrating the minimum motor

diameter for the given revolution and the frequency of the mains at

which the indications of the tester are reliable.

5. Power supply turn-off.

If within five minutes the L or R diode does not go on, the

tester is automatically turned off, and the ON diode goes off.

Note: It is not possible to turn the power supply off manually.

6. Battery charge signalling

•When the tester detects the battery charge amounts to 10% of

its full charge, the battery charge diode starts to blink

once a second. Measurements are still possible.

•If the battery is discharged, then the battery charge diode

is it continuously and it is impossible to perform

measurements. It is necessary to replace batteries. If the

battery is not replaced, then after five minutes the tester will be

automatically turned off.

7. Replacement of batteries

•Disconnect the measurement probes from the mains.

•Remove the elastic protection from the casing.

•Unscrew the rear part of the casing and remove it.

•Remove the battery from the tester and disconnect it.

•Connect a new battery, screw the rear flap and place the elastic

protection upon the casing.

8. Cleaning and maintenance

NOTE!

Use solely the maintenance techniques specified by

the manufacturer in the present operating manual.

The tester may be cleaned with a soft, damp cloth using all-

purpose detergents.

Do not use any solvents or cleaning agents which might scratch the

casing (powders, pastes, etc.).

The electronic system of the meter does not require maintenance.

9. Storage

In the case of storage of the device, the following

recommendations must be observed:

•Make sure the tester is dry.

•Should the tester be stored for a prolonged period of time, the

battery will be removed.

10. Dismantling and utilization

Worn-out electric and electronic equipment should be gathered

selectively, i.e. it must not be placed with waste of another kind.

Worn-out electronic equipment should be sent to a collection

point in accordance with the law of worn-out electric and electronic

equipment.

Before the equipment is sent to a collection point, do not

dismantle any elements.

Observe the local regulations concerning disposal of packages,

worn-out batteries and accumulators
