Use caution on live circuits. Voltages above 30V AC RMS, 42V AC peak, or 60V DC pose a shock hazard.
Do not use the tester in wet or damp environments or during electrical storms.
Do not use the tester near explosive vapors, dust or gasses.
Do not use the tester if it operates incorrectly. Protection may be compromised.
Do not apply voltage that exceeds the tester’s maximum rated input limits.
Never use the meter with CAT II installations when measuring voltages that might exceed the safety margin of 230 V above earth ground.
The unit is only intended to be used for short periods, typically less than 2 minutes, and must not be left plugged in for extended periods.
Vent slots should not be covered or obstructed.
The unit is intended for use in the vertical orientation only.
The unit must always be checked for any sign of damage prior to use. lf there are visual signs of damage do not use. Return the unit to provider for analysis. Visual signs of damage include checking the case exterior, pins and label. lf any are damaged DO NOT USE.
To verify the tester is working correctly, always first plug it into a known good socket prior to use.
lf the unit has suffered a mechanica! shock such as a drop, have it checked out by provider first.
The product has no user serviceable parts.
The product is designed to comply with EN 61010 and is rated to IP30.
The product will not detect reverse earth neutral.
The Socket Tester is intended as a first level fault indication tool and only checks for correct polarity.

6. Overvoltage/Installation Category

Voltage testers are categorized depending on the risk and severity of transient overvoltage that might occur at the point of test. Transients are short-lived bursts of energy induced in a system, e.g. caused by lightning strike on a power line.

The existing categories according EN 61010-1 are:

CAT I| A CAT I-rated meter is suitable for measurements on protected electronic circuits that are not directly connected to mains power, e.g. electronics circuits, control signals…
---|---
CAT II| A CAT II-rated meter is suitable for measurements in CAT I-environments and mono-phase appliances that are connected to the mains by means of a plug and circuits in a normal domestic environment, provided that the circuit is at least 10 m apart from a CAT III- or 20 m apart from a CAT IV-environment. E.g. household appliances, portable tools…
CAT III| A CAT III-rated meter is suitable for measurements in CAT I- and CAT II-environments, as well as for measurements on (fixed) mono- or poly-phased appliances which are at least 10 m apart from of a
CAT IV| CAT IV-environment, and for measurements in or on distribution level equipment (fuse boxes, lighting circuits, electric ovens).
CAT IV| A CAT IV-rated meter is suitable for measuring in CAT I-, CAT II- and CAT III-environments as well as on the primary supply level. Note that for all measurements on equipment for which the supply cables run outdoors (either overhead or underground) a CAT IV meter must be used.

Warning:

This device was designed in accordance with EN 61010-1 installation category CAT II 230 V. This implies that certain restrictions in use apply that are related to voltages and voltage peaks which can occur within the environment of use. Refer to the table above.

This device is only suitable for measurements up to 230 V in CAT II

7. Pollution Degree

IEC 61010-1 specifies different types of pollution environments, for which different protective measures are necessary to ensure safety. Harsher environments require more protection, and the protection against the pollution which is to be found in a certain environment depends mainly on the insulation and the enclosure properties. The pollution degree rating of the DVM indicates in which environment the device may be used.

Pollution degree 1| No pollution or only dry, nonconductive pollution occurs. The pollution has no influence. (only to be found in hermetically sealed enclosures)
---|---
Pollution degree 2| Only nonconductive pollution occurs. Occasionally, temporary conductivity caused by condensation is to be expected. (home and office environments fall under this category)
Pollution degree 3| Conductive pollution occurs, or dry nonconductive pollution occurs that becomes conductive due to condensation that is to be expected.
(industrial environments and environments exposed to outside air – but not in contact with precipitation)
Pollution degree 4| The pollution generates persistent conductivity caused by conductive dust or by rain or snow. (exposed outdoor environments and environments where high humidity levels or high concentrations of fine particles occur)

Warning : This device was designed in accordance with EN 61010-1 pollution degree 2. This implies that certain restrictions in use apply that are related to pollution which can occur within the environment of use. Refer to the table above.

This device is only suitable for measurements in Pollution degree class 2 environments.

9. Operation

Performing Tests and Measurements

The socket voltage tester is designed to assist users in determining the presence and level of electrical voltage in standard wall outlets and sockets.

This essential tool is intended for both professional electricians and homeowners to ensure the safety and functionality of electrical circuits and outlets.

With this socket tester you can check whether sockets, cable reels and extension cords are connected correctly. It detects whether the socket is connected with the correct polarity and shows wiring errors.

Warning:

This device only works on Live (L1) and Neutral (N) networks (TN network):

230V between L1 and N connection. N connection is almost 0V

This device doesn’t work on Live (L1) and Live (L2) (IT network):

230V between L1 and L2 connection. L1 and L2 gives 115V between Earth and L1 or L2

Visual Indicators:

The tool is equipped with a series of LED lights. The socket tester will light up GREEN, GREEN, OFF and the buzzer is continuously on for correct polarity. Any other combination indicates a fault.
