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 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.

Disposal of used batteries

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 this symbol indicating that they cannot be disposed of in 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 inInformation Testboy

TV 225 Description The TV225 digital flexible clamp multimeter can be used to test DC and AC voltage, alternating current, frequency, resistance and continuity. The electrical parameter to be measured is detected automatically so there is no need for the user to carry out any settings.

Operation Use This multimeter is extremely easy to operate: the electrical parameter to be tested and the correct test range are selected automatically without the user having to select specific functions.Operation Testboy

TV 225 21 ENGLISH ENGLISH ENGLISH The measured value is then shown on the LC display. Switching on/off Switching on: press and hold down the ON/OFF button [7] until you hear a beep. Switching off: press the ON/OFF button [7]. You will hear a short beep and the display will go off. Automatic switch-off When there is no signal to be measured and if no buttons are pressed, the instrument will switch off automatically after five minutes. Display backlight Press the button with the sun symbol [5] to switch on the display backlight. Press the button again to switch the backlight off. Lighting of the measurement location Press the button with the torch symbol [6] to light up the measurement location. Press the button again to switch off measurement location lighting. Reading memory (HOLD) To save the reading (e.g. if it is difficult to see the display at the measurement location), press the HOLD button [8]. The symbol "H" appears on the display. The reading is retained until you press the button again. Voltage/resistance/continuity testing Connect the red test lead to the "V, Ω, o)))" socket [10] and the black test lead to the "COM" socket [9]. Use the measurement probes to carry out testing parallel to the voltage source or the resistance. The instrument automatically detects whether DC or AC voltage is present, or switches to resistance testing. If the resistance values are lower than 50 Ω (continuity), you will hear a continuous beep. The reading appears on the main display. Where DC voltage is detected, "DC" is displayed. The polarity of the measured voltage in relation to the reference point (black test lead) is also displayed. Negative polarity is indicated by "-". Where AC voltage is present, "AC" is displayed, and the frequency of the AC voltage is shown in the auxiliary display. The order of automatic detection is as follows: AC voltage → DC voltage → AC, resistance/continuityOperation 22 Testboy

TV 225 AC testing Release the test loop locking mechanism, guide the flexible test loop around the conductor to be tested and close the test loop again (see figure). Ensure that the test loop is correctly secured. The mark on the locking mechanism lines up with the "" symbol. Automatic detection switches the instrument to the relevant AC test range. The reading appears on the main display, and the frequency appears on the auxiliary display

When simultaneously measuring the voltage (via the test leads) and current (via the test loop), the main display shows the voltage value and the auxiliary display shows the current instead of the frequency. Position fault The accuracy of the current reading greatly depends on the position of the conductor in the test loop. Please also note that electrical and magnetic fields affect the test result, and the measurement location should be as free from interferences as possible. Optimum test radius Position fault

>60 mm ± 5.0 % Definition of the measurement categories Measurement category II: Measurements on circuits directly connected to low voltage networks electrically via plug. Typical short-circuit current < 10 kA Measurement category III: Measurements within the building installation (stationary consumer devices with non-plug-in connection, distributor connection, permanently installed equipment in the distributor). Typical short-circuit current < 50 kA Measurement category IV: Measurements at the source of the low voltage installation (meters, mains connection, primary overcurrent protection). Typical short-circuit current >> 50 kA To establish the measurement category in a combination of test lead and measuring instrument, the lowest category, of either the test lead or the measuring instrument, always applies. Replacing the battery If the battery symbol is displayed, the batteries are dead and need to be replaced. To do this, switch off the instrument and remove any test leads. To open the battery compartment on the back of the instrument, undo the holding screw using a Phillips screwdriver size 1. Remove the cover and replace the old batteries with new ones. 3 AAA (Micro) 1.5 V batteries are required.

Batteries must not be disposed of with normal domestic waste. There will be a collection point near you! Maintenance The instrument does not require special maintenance when used as specified in these operating instructions.Test ranges 24 Testboy
