Safety Instructions
PURPOSE OF USE AND OPERATING PRINCIPLE OF THE DETECTOR
The device is intended for non-contact detection of alternating-current
voltage (NCV) in the range 12-1000 V AC 50/60 Hz on the basis of a light and
sound signal. The device enables the differentiation of a live conductor („L”
phase) and a neutral conductor („N”).
WARNING Carefully read this user’s manual before first using the device and keep it with the product so that a user can become acquainted with it. Prevent this user’s manual from being destroyed.
WARNING In order to prevent possible injury by electrical shock or other types of injuries, adhere to the following:
- Please use this device exclusively according to the instructions provided in this user’s manual. Otherwise, the protective function provided by this device may be affected.
- Do not use this device when its power indicator is not lit, i.e. button in fig. 1, position 7 is not lit.
- Prior to performing actual measurements, check the correct voltage detection indication by detecting a known voltage in the range 12-1000 V AC 50/60 Hz to ensure that the device is in proper working order.
- When using this device, voltage may be present in its vicinity even if no sound or light warning is being emitted. This device indicates the effective voltage value only in the case where the alterna-ting voltage creates a sufficiently strong electrostatic field. If the strength of this field is very low, the device may not necessarily be able to detect this field. The functionality of this device may be affected by the following factors, including, though not exclusively, the factors listed below:
- Shielded conductor/cable.
- Thickness and type of insulation.
- Distance from the voltage source. e) Differences in the construction on of the power socket, etc.
- Complete insulation.
- Do not use this device when it is damaged or when not working correctly. Prior to using it, check that its probe is not cracked or otherwise damaged. In the event of any doubts, please arrange a timely repair of the device.
- Please, do not use a nominal voltage greater than the voltage designated on this device.
- When detecting alternating-current voltage greater than 30 V, special measures must be taken to prevent injury by electrical shock.
- Only perform measurements with the device with dry hands and when the measured object and environment are dry.
- Use proper protective equipment in accordance with the requirements of local and nation regulations.
Warning
-
For safety reasons, do not use the CAT Ill over-voltage category measuring device to measure electrical installations requiring a level IV over voltage category (CAT IV). The specifications for the individual over voltage categories CAT Ito CAT IV according to EN 61010-1 are provided below and are illustrated in the following picture.
-
Electrical installations requiring an over volt-age category IV (CAT IV) measuring device are the following: Electrical equipment located in the near vicinity of a building’s power source, between the input into the building (junction box) and the main switchboard. Such equipment may include, for example, tariff electricity meters and primary over voltage protection devices.
-
Electrical installations requiring an over voltage category III (CAT III) measuring device are the following: Equipment that is part of the electrical installation in a building. Such equipment includes power sockets, circuit breaker boards and certain other mains power control installations. The measuring device meets the requirements for the CAT III protection level only up to the specified voltage value; and it must not be used for measuring installations requiring the CAT III level which are at higher voltages.
-
Over voltage category II (CAT II) includes equipment intended to be powered from the building installations. This applies both for equipment connected to power sockets as well as for permanent-ly connected equipment.
-
Over voltage category I (CAT I) covers equipment intended for connection to mains power, where the equipment incorporates measures that significantly and reliably reduce transitional overvolt-age to a level that cannot present a hazard. Overvoltage category I (CAT I) is not relevant to norm EN 61010-1, according to which the measuring device has been tested.
-
A measuring device with a higher overvoltage category (CAT) can be used to measure installations belonging to a lower overvoltage category, e.g. a multimeter with CAT III protection for the defined voltage can be used to measure CAT II installations in the permitted voltage range, however, a CAT III multimeter cannot be used for measuring installations belonging in category CAT IV.

Operating instructions
-
Turning the device on and off Turning on: Press the On/Off button (fig. 1, position 7) for more than 1 second. The button must light up. In the event that the button does not light up, do not use the device and arrange a remedy for this condition. Turning off: Press the same button, which will turn off the button’s light.
-
Turning the flashlight on and off Turning on: Press the button with the flashlight symbol (fig. 1, position 8) to turn on the flashlight. Turning off: Press the button with the flashlight symbol again to turn the flashlight off. If the flashlight is not turned off, then it will turn itself off automatically after approximately 5 minutes.

Detecting alternating-current voltage The detection of alternating-current voltage works on the principle of non-contact detection (NCV) without a conductive connection of the device with the tested object. Place the test probe (fig. 1, position 1) of the device on the tested object or if this is not possible as close as possible to the tes-ted object. If the device detects voltage in the tested object, the light signal head (fig. 1, position 2) will flash read and will be accompanied by an intermittent sound signal at a varying frequency. The signal intensity (high, medium, low) will be shown by means of signal intensity indicators, see fig. 1, positions 4, 5, 6. For example, placing the test probe (fig. 1, position 1) directly on the insulation of a conductor with a voltage of 230 V — 50 Hz („L” phase) is accompanied by an intermi-ttent warning light signal of the highest frequency on the light signal head (fig. 1, position 2), an intermittent sound signal of the highest frequency and likewise all the signal intensity indicators are lit (fig. 1, position 4) red and the remaining indicators are lit yellow. If the device’s test probe is moved away from the conductor by only 1 cm, the sound and light signal frequency will be reduced and the signal intensity indicators will be lit with medium intensity (fig. 1, position 5). At a distance of 1.5 cm from the same conductor, the frequency of the warning light and sound signals will be even lower than in the previous example and the low signal intensity indicators (fig. 1, position 6) will be lit. At a distance of 4 cm from the same conductor, the device will not emit any light or sound warning signal, i.e. as if the examined conductor were not live (appears to not be under voltage). From the aforementioned examples the limitation that can distort measurement results are evident, e.g. the distance of the conductor from the device’s probe in masonry, environmental shielding of the conductor, etc. If for example the live conductor is deeper inside a masonry wall and the detector is not emitting any warning signal, it does not mean that the conductor is not live or that there is no live conductor in the masonry wall.
WARNING With respect to the possible circumstances, to ensure protection against injury by electrical shock, it is necessary to take into consideration all circumstances that may affect the voltage measurement results. -
Distinguishing a „neutral” conductor („N”) and a live conductor („L” phase). Place the device’s probe on to the insulation of the conductor, or into the power socket hole as requi-red. If this is an „L” phase, the device will emit a high frequency intermittent light and sound warning signal, see the paragraph describing the detection of alternating-current voltage. In the case, where this is a „neutral” conductor („N”), then the frequency of the light and sound signal will be lower and with a lower signal intensity than in the case of the „L” phase, or there may even be no signal at all.
-
Automatic shut off If this device is not used for approximately 5 minutes and if no voltage signal is detected, then the device will turn itself off automatically.
-
Insufficient battery voltage indicator If the power voltage in the battery is lower than 2.6 V, then the power indicator will flash 3 times, the buzzer will beep and the device will turn off automatically. Please replace the batteries in a timely manner. A flat battery may negatively affect measurement results.
