USER MANUAL TV 333 Testboy

WARNING An additional source of danger is posed my mechani- cal parts which can cause severe personal injury. Objects can also be damaged (e.g., the instrument it- self can be damaged).

WARNING An electric shock can result in death or severe injury. It can also lead to property damage and damage to this instrument.

WARNING Never point the laser beam directly or indirectly (on re- flective surfaces) towards the eyes. Laser radiation can cause irreparable damage to the eyes. You must first deactivate the laser beam when measuring close to people.Notes Testboy

TV 333 19 ENGLISH General safety notes

WARNING Unauthorized changes or modifications of the instru- ment are forbidden – such changes put the approval (CE) and safety of the instrument at risk. In order to operate the instrument safely, you must always ob- serve the safety instructions, warnings and the infor- mation in the "Proper and Intended Use" Chapter.

WARNING Please observe the following information before using the instrument: | Do not operate the instrument in the proximity of electrical welders, induction heaters and other elec- tromagnetic fields. | After an abrupt temperature fluctuation, the instru- ment should be allowed to adjust to the new tem- perature for about 30 minutes before using it. This helps to stabilize the IR sensor. | Do not expose the instrument to high temperatures for a long period of time. | Avoid dusty and humid surroundings. | Measurement instruments and their accessories are not toys. Children should never be allowed access to them! | In industrial institutions, you must follow the acci- dent prevention regulations for electrical facilities and equipment, as established by your employer's liability insurance organization.Notes 20 Testboy

TV 333 Disposal For Testboy customers: Purchasing our product gives you the opportunity to return the instrument to collection points for waste electrical equipment at the end of its lifespan.

The EU Directive 2002/96/EC (WEEE) regulates the return and recycling of waste electrical and electron- ics equipment. As of 13/08/2005, manufacturers of electrical and electronics equipment are obliged to take back and recycle any electrical devices sold af- ter this date for no charge. After that date, electrical de-vices must not be disposed of through the "nor- mal" waste disposal channels. Electrical devices must be disposed of and recycled separately. All de- vices that fall under this directive must feature this logo. Disposing of used batteries

As an end user, you are legally obliged (by the rele- vant laws concerning battery disposal) to return all used batteries. Disposal with normal house- hold waste is prohibited! Contaminant-laden batteries are labelled with the adjacent symbol which indicates the prohibition of disposal with normal household waste. The abbreviations used for heavy metals are: Cd = Cadmium, Hg = mercury, Pb = lead. You can return your used batteries for no charge to collection points in your community or everywhere where batteries are sold!Notes Testboy

TV 333 23 ENGLISH Five year warranty Testboy instruments are subject to strict quality control stan- dards. The instrument is covered by a warranty for a period of five years against malfunctions during the course of your daily work (valid only with invoice). We will repair production or mate- rial defects free of charge upon return if these have not been caused by misuse or abuse and if the instrument has not been opened.

TV 333 Operation Dear customer, we thank you for your acquiring the Digital Luxmeter Testboy TV333. With this product, you acquired a state-of-the-art device. We kindly request the user to respect this operating manual to preserve this condition and to ensure safe operation. Prescribed Use The Digital Luxmeter Testboy TV333 is a high-precision meas- uring instrument for the precise measuring of the luminance and the incidence of light on a particular area. The measurement is performed via a photoelectric cell and the measuring result is indicated in four measuring ranges on the LC display. The volt- age supply is ensured by a 9V alkaline battery of the type 6F22. Do not expose the device directly to water or humidity; the housing is not water-proof! Clean the exterior of the device only with a dry and lint-free cloth. Do not use cleansing agents! A use different from the one described above leads to damaging of this product. Furthermore, it involves dangers such as e.g. short-circuit, burns, etc. The entire product must not be opened, modi- fied or rebuilt.

TV 333 25 ENGLISH Safety Instructions Any claims for guarantee will become invalid in the event of damage that results from the non-observance of the op- erating manual. We do not accept responsibility for such damage. Nor do we accept responsibility for damage to property or for personal injuries caused by improper use or non-observance of safety instructions. Guarantees will not be accepted in any such case. The unauthorized conversion and/or modification of the product is inadmissible because of safety and approval reasons (CE). This device is not a toy. Keep the device out of reach of chil- dren! Do not expose the device to mechanical stress, to mois- ture or liquids. Only use the device outdoors under appropriate weather condition or with appropriate protection. The light sen- sor or the device must not be heated by the light source. Keep sufficient distance to light sources with strong heat develop- ment. Information on the Correct Luminance The luminance is measured in lux. The adaptability of the hu- man eye is almost unlimited. This easily leads to demanding of the eye visual performance even if the illumination is not suffi- cient. If there is no light or the illumination is not sufficient, the eye can fulfil its visual performance only with great effort or even cannot see. Very often, this involves eye injuries the num- ber of accidents increases. With the Digital Luxmeter Testboy TV333 you acquired a prod- uct by means of which you can verify everywhere if the lumi- nance is sufficient for the normal visual performance (i.e. every- day tasks). Eyesight means the detection of brightness and col- our differences, form, motion as well as distance. Only with the correct luminance, the eye can fulfil its visual performance. Therefore, sufficient illumination is so important. Concerning light, we often save at the wrong end. Dark zones give an un- friendly atmosphere. Allow yourself more light.Operation 26 Testboy

TV 333 The kind of illumination influences the information that is trans- mitted by the eye to the brain. Increase the illumination where precise seeing is necessary. In rooms with an luminance inferior to 30 lux, the danger of accidents increases! Older people need more light, because their visual performance decreased. A 60-year old needs approx. twice the light of a 30- year old. Description of the Device

TV 333 27 ENGLISH Carrying out Measurements Before commissioning, please observe the instructions concerning the Prescribed Use as well as the Safety In- structions and the Technical Data. | Turn the ON/OFF switch (2) to ON. | Remove the protective cap from the light sensor and hold it horizontally ensuring that the light hits | the light sensor vertically. Avoid shadows of your own body in direction of the sensor. | Read the value (1) indicated on the display. In the measuring range 2000 lux, the indicated value corresponds to the inten- sity of light in lux. | In the measuring range of 20000 lux, you have to multiply the indicated value on the display by 10; in the measuring range of 100000 lux, you have to multiply it by 100 to determine the correct light intensity. | In case of overflow indication ("1" is indicated on the display), please switch to the next measuring range (3) to determine the correct light intensity. | After the measuring process, please switch off the device (On/Off switch to "OFF") and put the | protective cap back onto the sensor.Operation 28 Testboy

TV 333 Replacing the Batteries The device is already equipped with a built-in 9V alkaline bat- tery of the type 6F22 when being delivered. As soon as the Low-Bat indication appears on the display, please replace the battery because otherwise, the precision of the indication is no longer guaranteed. To replace the battery, proceed as follows: | Remove the battery cover on the back of the device by push- ing carefully. | Remove the empty battery and replace it by a new one of the same type. | Ensure correct and secure position of the battery. | Put the battery cover back onto the device and close the de- vice by pushing carefully back. | The user is legally obliged (old battery regulation) to return all used batteries (from round cells to lead storage batteries) to a specialist dealer’s shop where there are special facilities (col- lecting boxes). It is forbidden to dispose of batteries in the garbage bin or litter.Operation Testboy
