[. . . ] To switch the device back on, first of all place the function switch at the position OFF and then at a measurement function. There is a risk of receiving an electric shock or serious injuries if the following safety instructions are not strictly observed!Thereby, inspect especially carefully the insulation in the area of the connections. Do not use the multimeter in localities subject to explosive gases, vapours or dust. [. . . ] Button HOLD Display Battery compartment cover Measuring leads with measurement prods Temperature sensor (on the red adaptor) Measuring leads with measurement plugs Battery compartment (on the rear) To switch the multimeter off, move the function switch q back into the position OFF. Should the battery symbol ( ) be indicated in the lower left corner of the display z, this indicates that the battery is weak and must be replaced. Should both battery symbols y ( ) be exhibited in the display, false measurement results will be given due to feeble battery performance. Replace the battery as soon as the battery symbols y ( ) or ( ) are indicated, this will avoid both false measurements and the possible occurrence of an electric shock or an injury. If the device is not to be used for an extended period, the battery must be removed to avoid potential damage caused by it possibly leaking.

Always remove the measuring leads from the object being tested before switching over to a new function or a different area of measurement. Dirt and moisture diminish the insulation resistances and this could, especially with large voltages, lead to you receiving an electric shock. The device may only be utilised within the given measurement ranges. Before being taken into use, the device must be tested for correct functioning (e. Steps are to be taken to ensure that the measuring leads are in a faultless condition. If the object being tested is not correctly connected to the multimeter with the regard to polarity, the indicated measurement value is preceded by a minus sign. With component measurements, the component being tested may not be located within a switching, as this would falsify the measurement results. Should this limit be exceeded, there is a risk of both damaging the device and an imperilment of the user. Disconnect the measurement prods from the object being tested before selecting a different area of measurement. Press the button RANGE e once to switch from the automatic to the Press the button RANGE e once again to show the various measurement conclusions, one after the other. Subject to the fed voltage, the display of the measurement conclusions begins with one of the following indicator formats: -> Measured value in Millivolt (mV) with one decimal place -> Measured value in Volt (V) with three decimal places -> Measured value in Volt (V) with two decimal places -> Measured value in Volt (V) with one decimal place -> Measured value in Volt (V) without decimal places After this, the display of measurement conclusions starts again from the beginning. To switch back to automatic measurement conclusions, hold the button RANGE e pressed down for approx. With open measurement prods and an automatic measurement conclusion, a vacillating measurement conclusion appears in the mV range, resulting from the high input sensitivity. During the actual measurement a stable and correct indication is given. Before attachment of the measurement leads, the object being tested must be de-energised, so as not to damage the device or the object being tested. In cases of doubt, the freedom from energy must be proved by measurement. [. . . ] : RMS: root mean square) in electrical engineering, the "effective value" is to be understood, in other words, the square median value of a transitory variable signal. +/- 15 points) With colour temperature** 2850 K calibrated on standard white light with 2856 K Lux (lx) is the international unit for specific light radiation. ** The colour temperature is defined as the temperature to which a black object must be heated so that it renders the light of the to be defined colour. You receive a 3-year warranty for this device as of the purchase date. [. . . ]
