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 irreparable damage to the eyes. You must first deactivate the laser beam when measuring close to people.Notes Testboy

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 instrument: | 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 prevention regulations for electrical facilities and equipment, as established by your employer's liability insurance organization.Notes

TV 218 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 WEEE directive regulates the return and recycling of electrical appliances. Manufacturers of electrical appliances are obliged to take back and recycle all electrical appliances free of charge. Electrical devices may then no longer be disposed of through conventional waste disposal channels. Electrical appliances must be recycled and disposed of separately. All equipment subject to this directive is marked with this logo.

As an end user, you are legally obliged (by the relevant laws concerning battery disposal) to return all used batteries. Disposal with normal household 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 218 Operations Thank you for choosing the Testboy

TV 218 should be used in CAT-III systems for measuring voltages that do not exceed 300 V (AC or DC) in relation to the earthing. Operating This meter should be allowed to acclimate with the surroundings before measuring. | The user of this clamp meter must comply with all relevant safety regulations. | The meter may display false readings when used in the vicinity of devices which are generating noise or interference. | This meter should only be used as described in these instructions. Any other use could affect this device's safety system. | To avoid damaging the meter, never exceed the maximum input values listed in the technical specifications. | Always make sure that the mode selection switch is in the proper position before starting each measurement. | You must use extra caution when working around uninsulated wires or busbars. | Any accidental contact with a conductor can cause an electrical shock. | Be careful when working with voltages over 60 VDC or over 30 VAC RMS. Such voltages pose a risk of electric shock. | The clamping jaws must always be taken off the test circuit before switching to another function. | Keep your fingers behind the protective ring while measuring. | To avoid false readings: Change the batteries whenever the icon appears.Operations Testboy

TV 218 27 DEUTSCH DEUTSCH ENGLISH | Before each measurement, make sure that the clamp meter is in perfect condition. Test the meter on a known current source to make sure it is functioning properly before actual use. | The "+" sign on the clamping jaws indicates the direction of current flow during DC mode (as shown in the illustration). A Direction of current B Protective ring C Data Hold D Mode selector switch

TV 218 Safety information for this product | Before opening the meter, always disconnect all electrical power sources. Also make sure to discharge yourself since static electricity could destroy internal components. | Only qualified technicians who are familiar with these instructions are permitted to adjust, service or repair the clamp meter. | A person is considered qualified when he understands the set- up, design and functionality of the facility and comprehends the associated risks. A qualified operator is an experienced professional who is authorized to switch the power on or off to circuits within the electrical facility. | When working with opened devices, remember that internal capacitors can retain life-threatening voltage levels even after they have been switched off. | Stop using the meter if you experience any errors or unusual operations. Make sure that the meter cannot be used until it has passed an inspection. | Remove the batteries if you do not plan on using the meter for an extended period of time. Do not store the meter in a room that is overly humid or warm. | Operate with extreme caution when working around uninsulated wires and busbars. Touching such components and wires can lead to electric shock! Make sure that you are using the appropriate protective mechanisms!Operations Testboy

TV 218 29 DEUTSCH DEUTSCH ENGLISH Maintenance and cleaning

In order to reduce the risk of electric shock, do not permit any moisture to penetrate inside the housing.

| Clean the housing periodically with a dry cloth. Do not use cleaning agents. Do not use abrasive cleansers or solvents.Operations

TV 218 Changing the batteries

Minimize the risk of electric shock. Remove the clamping jaws from the test circuit and switch off the meter before you remove the rear housing.

Procedure | If the battery voltage is too low, the battery icon will appear on the LCD screen. Replace the battery when this icon appears. | Set the range switch in the OFF position. | Remove the rubber holster. Unscrew the screw (A) on the rear side with a screwdriver. Remove the used batteries and replace with two new 1.5-V button cell batteries (type SR 44/LR 44). | Screw on the battery cover and replace the rubber holster.

Do not dispose of batteries in normal household rubbish! Use an authorised local collection point!Operations Testboy

TV 218 31 DEUTSCH DEUTSCH ENGLISH Explanation of the buttons Select Switch between DC (default) or AC mode. Zero Press the Zero key to zero-out the display reading. D-H Data Hold button (also referred to as the measurement save button). Press this button in order to save and display the current measured value. The H-D icon on the display confirms the active function. The measurement process is interrupted during the data-hold function! Function select switch The function select switch is used for selecting the measurement range and for switching off the meter.Operations

TV 218 Operating Instructions If the measured current exceeds the set value over a long period of time then the meter can heat up. This can impair the functional reliability of the internal circuitry. To avoid discharges or inaccurate readings, do not measure currents on high-voltage lines (over 300 V). The meter has been set at the factory for DC mode. Measuring AC currents | Set the function switch as needed. | Use the Select button to choose the AC current range "AC T-rms". | Encircle one of the wires being measured with the current transformer (the clamping jaws) Make sure that the clamp is completely closed. | Read the measured value displayed in the "True-RMS" field. Measuring DC currents | Set the function switch as needed. | Encircle the wire being measured with the current transformer (the clamping jaws). Make sure that the clamp is completely closed. Make sure the polarity indicator is correct! | Read the measured value. | It may be necessary to zero-calibrate before measuring. To calibrate, open the close the clamps repeatedly (with no wire inside). Then wait until the displayed value has steadied and press the ZERO button. The value in the display should change to about 0.00 and ZERO appears in the display.Technical specifications Testboy
