Unfavourable ambient conditions are: - excessive dampness or humidity - dust or combustible gases, vapours or solvents - electrical storms or stormy conditions and strong electrostatic fields, etc. Use other than that described above will damage the product and may involve other risks, such as short circuit, fire and electric shock etc. -
Page 5: Safety Instructions
Safety Instructions Please read the complete instructions carefully before starting operation. The information contained is important for correct ope- ration. The warranty will lapse in case of damage caused by failure to comply with these operating instructions! We shall not be held lia- ble for any consequential damage or loss! We do not accept any liability for personal injury or damage to pro- perty caused by incorrect handling or non-observance of the safety... - Page 6 In commercial institutions, the accident prevention regulations of the Employer’s Lia- bility Insurance Association for Electrical Systems and Operating Materials are to be observed. In schools, training centres, computer and self-help workshops, handling of measu- ring instruments must be supervised by trained personnel in a responsible manner. Always make sure before measuring voltages that the measuring instrument is not set to a current measuring range.

Page 9: Carrying Out Measurements
Carrying out Measurements In no event exceed the max. permitted input values within the over- voltage category III. The frequency of the alternating volumes may not exceed 400Hz! Do not contact circuits or parts of circuits if there could be higher voltages than 25V ACrms or 35V DC pending within them ! Danger! Before measuring, check the connected measuring lines for damage such as, for example, cuts, cracks or squeezing. - Page 10 b) Resistance measurement, diode test,acoustic continuity check and capacity measurement Make sure that all the circuit parts, switches and components and other objects to be measured are disconnected from the voltage and currentless at all times. Proceed as follows for the measurement: - Connect the black measuring line with the COM socket (7) and the red measuring line with the VΩ-socket (6) till they are plane at the measuring instrument.
- Page 11 c) Frequency measurement In no event exceed the max. permitted input values. Do not contact circuits or parts of circuits if you measure voltages higher than 25V ACrms or 35V DC pending within them. Proceed as follows to measure the frequency: - Connect the black measuring line with the COM socket (7) and the red measuring line with the VΩ-socket (6) till they are plane at the measuring instrument.
- Page 12 e) Current measurement in the µA- and mA ranges You can measure currents of up to 400µA in the µA range and currents of up to 400 mA in the mA range. Both current measuring ranges are provided with fuses and thus protected against overload.
- Page 13 f) Current measurement in the 10A range In this range, currents of up to 10A DC/AC can be measured. The current meas - urement range is provided with a fuse and thus protected against overload. Proceed as follows to measure direct currents: - Connect the black measuring line with the COM socket (7) and the red measuring line with the 10A socket (8).
- Page 14 g) Speed measurement The speed can be measured at petrol engines with and without ignition distributors. The speed is measured in an inductive manner at an ignition cable by means of a clamp-on meter. Use this function only for insulated cables to avoid possible contacts! When connecting make sure that wires or clothes, hair etc.

Page 15: Special Functions
Special Functions Auto power OFF function In order to avoid that the operating life of the battery is shortened unnecessarily, an automatic switch-off function has been implemented. If a button has not been pres- sed or the rotary switch has not been activated for more than 35 minutes, the mea- suring instrument will be switched off. -

roded Moreover the vapours are detrimental to health and explosive. Nor should sharp-edged tools such as screwdrivers, metal brushes etc. be used for cleaning purposes. Periodically check the technical safety of the instrument and measuring lines, e.g. check for damage to the housing or squeezing etc. Always observe the following safety instructions before cleaning the device: Live components may be exposed if covers are opened or parts are removed (unless this can be done without tools). -

Disposal of flat batteries/accumulators! You as the ultimate consumer are legally obliged (Regulation on Spent Batteries) to return all dead batteries and accumulators. Disposal in the household waste is prohibited! Batteries/accumulators containing hazardous substances are marked by the opposite symbols. These symbols also indicate that it is prohi- bited to dispose of these batteries in the household waste. -
