Phase Spin Direction Test; Cleaning And Maintenance; Storage; Dismantling And Utilization - Sonel TKF-12 User Manual


If phase-to-phase voltage exceeding 760 V 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


Connect the measurement probes of the TKF-12 tester to the points where there is the expected
three-phase voltage (see the illustration below).

3. Cleaning and maintenance

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.

4. Storage

In the case of storage of the device, the following recommendations must be observed:

Make sure the tester is dry.

5. 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

If the phases at the given measurement points are compliant with the L1, L2,
L3 description, the green R diode of the tester will go on; otherwise the red L
diode will go on.

The light of the given neon lamp (L1, L2, L3) signalises a phase-to-phase
voltage exceeding 136 V 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.
Use solely the
specified by the manufacturer in the present
operating manual.
