TB 312 Notes General safety notes

WARNING Unauthorised modification and/or changes to the instrument are not permitted, for reasons of safety and approval (CE). In order to ensure safe and reliable operation using the instrument, you must always observe the safety instructions, warnings and the information contained in the section "Intended use".

WARNING Please observe the following information before using the in- strument: | Do not operate the instrument anywhere near electrical welders, induction heaters or other electromagnetic fields. | Further to abrupt temperature fluctuation, the instrument must be allowed to adjust to the new ambient temperature for approx. 30 minutes before using it, in order to stabilise the IR sensor. | Do not expose the instrument to high temperatures for a long period of time. | Avoid dusty and humid environments. | Measuring instruments and their accessories are not toys, and must be kept out of the reach of children! | In industrial facilities, the accident prevention regulations for electrical systems and equipment, established by the em- ployer's liability insurance association, must be observed.Notes Testboy

Please observe the five safety rules: 1 Disconnect 2 Ensure that the instrument cannot be switched back on again 3 Ensure isolation from the power supply (check that there is no voltage on both poles) 4 Earth and short-circuit 5 Cover adjacent live parts

Intended use The instrument is intended strictly for use in applications described in the operating in- structions. Any other usage is considered improper and forbidden, and can result in ac- cidents or the destruction of the instrument. Any such application will result in the im- mediate expiry of all guarantee and warranty claims on the part of the operator against the manufacturer.

Remove the batteries if the instrument is not in use for a long period of time, in order to protect the instrument from damage.

We assume no liability for damages to property or personal injury caused by improper handling or failure to observe the safety instruc- tions. Any warranty claim expires in such cases. An exclamation mark in a triangle indicates safety notices in the operating instruc- tions. Read the instructions completely before beginning the initial commissioning. This instrument is CE-approved and thus fulfils the required guidelines.

Disposal Dear Testboy customer: purchasing our product gives you the option of returning the instrument to suitable collection points for waste electrical equipment at the end of its lifespan.

The WEEE directive regulates the return and recycling of elec- trical 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 appli- ances must be recycled and disposed of separately. All equip- ment subject to this directive is marked with this logo.Notes 32 Testboy

As an end user, you are legally obliged (battery law) to return all used batteries; disposal with normal domestic waste is prohibited! Batteries containing contaminant material are labelled with adja- cent symbols indicating the prohibition of disposal with normal domestic waste. The abbreviations used for the respective heavy metals are: Cd = cadmium, Hg = mercury, Pb = lead. You can return your used batteries free of charge to collection points in your community or anywhere where batteries are sold!

Certificate of quality All activities and processes carried out within Testboy GmbH relating to quality are monitored permanently within the framework of a Quality Management System. Fur- thermore, Testboy GmbH confirms that the testing equipment and instruments used during the calibration process are subject to a permanent inspection process. Declaration of conformity The product conforms to the most recent directives. For more information, go to www.testboy.deOperation Testboy

The multimeter is a valuable aid for all standard measurement tasks in trade and industry as well as for electronics hobbyists. Scope of delivery | Multimeter TB 312 | Safety test leads (CAT III 1000 V) | Operating instructions | PC software (CD) | USB cable Safety precautions The TB 312 left the factory with its safety features in perfect 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 test leads or equivalent test leads that meet the correct measurement category CAT III 1000 V.Operation 34 Testboy

TB 312 | In order to avoid risk of electric shock, you must observe the specified precautions when working with voltages greater than 70 V (35 V) DC or 33 V (16 V) eff AC. These values represent the limits of safe-to-touch voltages in accordance with DIN VDE. (Values given in brackets apply to medical or agricultural areas, for example) | Before taking each measurement, ensure that the test lead and the test instrument are in perfect working order | The test leads and test probes must only be handled using the grips pro- vided. Avoid touching the test probes under any circumstances.

The test instrument must only be used for the measuring ranges specified.

According to the standard EN 61010-1, the following measurement categories are de- fined: Measurement category CAT II Measurements on circuits that are directly electrically connected to the network, via plugs in the home, office and laboratory. Measurement category CAT III Measurements on 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: meters, primary surge pro- tection, mains connection.Operation Testboy

TB 312 45 DEUTSCH ENGLISH Maintenance The instrument does not require special maintenance when used as specified in these operating instructions. Cleaning Use a damp cloth and mild household detergent to clean the instrument should it be- come soiled through daily use. Never use aggressive cleaning agents or solvents to clean the instrument. Changing the batteries Change the batteries when the battery icon is displayed. Remove the test leads from the instrument before changing the batteries! Remove the two screws on the rear of the instrument below the fold-down pedestal, open the battery compartment and remove the spent batteries. Insert new batteries (6 x 1.5 V AAA Micro). Ensure that the polarity is correct. Replace battery compartment and screw tight.

Only use the batteries specified! Batteries must not be disposed of with normal domestic waste! Observe the statutory regulations pertaining to disposal!

Changing the fuse When you need to change the fuse, first remove the test leads from the instrument and remove the battery compartment's two screws on the rear behind the fold-down pedes- tal. Carefully remove the battery compartment lid, lift off the relevant protective cap of the fuse that is to be changed and replace the defective fuse with one of the same sort (F 10 A / 1000 V or F 500 mA / 1000 V fuse). Replace the protective cap and retighten the screws of the battery compartment.

If the driver is not installed automatically, open the “drivers” folder on the CD Run the xxxInstaller.exe in the appropriate folder of your operat- ing system. The following operating systems are supported: Windows 2000, XP, 2003, Vista and Windows 7. Once the drivers have been installed successfully, a virtual COM port is generated. Please refer to the device manager for the assigned COM port (COM2, COM3, etc). Configure this COM port in the program's main window (top left) and press “Connection”. Depending on where the rotary selector switch is positioned on the multimeter, you will see a copy of the display in the top left section of the main window, with an XY plot beneath it, and on the right-hand side the data is transferred to a list that you can then easily save, transfer to EXCEL or print.Operation Testboy

You can change the view of the XY plot using other tools: You can change the time base (X-axis) by using the top arrows, and the Y-axis by using the side arrows.
