WARNING An additional source of danger is posed my mechanical parts which can cause severe personal injury. Objects can also be damaged (e.g., the instrument itself 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 reflective surfaces) towards the eyes. Laser radiation can cause irrepa- rable damage to the eyes. You must first deactivate the laser beam when measuring close to people.Notes Testboy

TB 313 25 ENGLISH General safety notes

WARNING Unauthorized changes or modifications of the instrument 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 observe the safety instructions, warnings and the information in the "Proper and Intended Use" Chapter.

WARNING Please observe the following information before using the in- strument: | Do not operate the instrument in the proximity of electrical welders, induction heaters and other electromagnetic fields. | After an abrupt temperature fluctuation, the instrument should be allowed to adjust to the new temperature 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 accident pre- vention regulations for electrical facilities and equipment, as established by your employer's liability insurance organiza- tion.Notes 26 Testboy

TB 313 Please observe the following five safety rules: 1 Disconnect. 2 Ensure that the instrument cannot be turned back on again. 3 Ensure isolation from the main supply voltage (check that there is no voltage on both poles). 4 Earth and short-circuit. 5 Cover neighbouring parts that are under live electrical load. Proper and intended use This instrument is intended for use in applications described in the operation manual only. Any other usage is considered improper and non-approved us- age and can result in accidents or the destruction of the instrument.

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 electronics equipment. As of 13/08/2005, manufacturers of electrical and electronics equip- ment are obliged to take back and recycle any electrical devices sold after this date for no charge. After that date, electrical de- vices must not be disposed of through the "normal" waste dis- posal channels. Electrical devices must be disposed of and re- cycled separately. All devices that fall under this directive must feature this logo.Notes 28 Testboy

TB 313 Disposing of used batteries As an end user, you are legally obliged (by the relevant laws concerning battery disposal) to return all used batteries. Dis- posal with normal household waste is prohibited! Contaminant-laden batteries are labelled with the adjacent sym- bol 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! Five year warranty Testboy instruments are subject to strict quality control standards. The in- strument is covered by a warranty for a period of five years against malfunc- tions during the course of your daily work (valid only with invoice). We will repair production or material defects free of charge upon return if these have not been caused by misuse or abuse and if the instrument has not been opened. Damage resulting from a fall or improper handling is excluded from the warranty.

Included in delivery | Multimeter TB 313 | Safety testing leads CAT III 600 V | Operating instructions | Holster | Temperature probe Safety precautions The TB 313 left the factory in proper and safe working order. In order to maintain this condition, the user must observe the safety notes contained in this manual.

CAUTION! Use only the enclosed safety measurement leads or equi- valent measurement leads that meet the correct measuring category CAT III 600 V.Operation Testboy

TB 313 31 ENGLISH | In order to avoid an electrical shock hazard you must observe the speci- fied precautionary measures when working with voltages greater than 120 V (60 V) DC or 50 V (25 V) eff AC. These values represent the specified limits of safe-to-touch voltages in accordance with DIN VDE (values given in brackets apply to medical or agricultural applications). | Before taking each measurement, ensure that the test leads and the measuring instrument are in a flawless condition. | The test leads and test probes must only be handled using the isolated grips. Avoid touching the tips of the test probes under all circumstances.

The test instrument must only be used for the specified measure- ment range. According to the standard EN 61010-1 the following measurement catego- ries are defined: Measurement Category CAT II Measurements on circuits that are electrically connected directly to the net- work, via plugs in the home, office and laboratory. Measurement Category CAT III Measurements on the building installations: Fixed consumer units, distributor connection, equipment fitted permanently to the distributor. Measurement Category CAT IV Measurements at the source of the low voltage installation: Meter, primary surge protection, main connection.Operation 32 Testboy

TB 313 Cleaning Use a damp cloth and mild household cleaning agent to clean the instrument should it become soiled through daily use. Never use aggressive cleaning agents or solvents to clean the instrument. Changing the battery Change the battery when the battery symbol is displayed. Remove the test leads from the measuring instrument before changing the battery or fuse! Remove the two screws on the rear of the instrument, open the battery com- partment and remove the used batteries. Insert new battery (1 x 9 V Block 6F22). Replace battery compartment cover and screw tight.

Only use the specified batteries! Do not dispose of batteries in normal household rubbish! Observe statutory regulations pertaining to disposal! Changing the fuse When changing the fuse, remove the measurement leads from the device and remove the screws on the rear of the device (two at the bottom, one at the top). Carefully remove the rear of the housing and replace the fuse with fuse of the same type (Fuse F 10 A / 1000 V). Replace screws and screw tight. The F200 mA fuse is self-resetting and therefore maintenance free.
