NOTE!
Use solely the maintenance techniques specified by the manufacturer in this user
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.
In the case of storage of the device, the following recommendations must be observed:

Make sure the tester is dry.
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 rechargea-
ble batteries.
2 Phase rotation direction test

Connect the measurement probes of the tester 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 green R diode of the tester will go on;
otherwise the red L diode will go on.

The light of the given indicator (L1, L2, L3) signalises a phase-to-
phase voltage exceeding
responding probe and one of the remaining probes.
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.
