User manual VOLTCRAFT VC-110

[. . . ] They contain important information for putting it into service and operating it. This should be noted also when this product is passed on to a third party. Therefore look after these operating instructions for future reference!A list of contents with the corresponding page numbers can be found in the index on page 29. [. . . ] - The currently measured value is indicated on the display - After measuring, remove the measuring lines from the measured object and turn the DMM off. - Plug the red measuring lead into the V measuring socket (8) and the black measuring lead into the COM measuring socket (7). As soon as a minus "-" appears for the direct voltage in front of the measured value, the measured voltage is negative (or the measuring tips have been mixed up). - After measuring, remove the measuring lines from the measured object and turn the DMM off. Do not measure any currents above 10 A in the 10A range and no currents above 200 mA in the µA/mA range, otherwise the fuses trigger. Always start current measurements at the highest measurement range and switch down to lower ranges if necessary. All current measuring ranges are secured with fuses and thus protected against overload. proceed as follows to measure AC voltages "A-AC": - Turn the DMM on and select measuring function "A". The table shows the different measuring functions and possible measuring ranges. The measured value is indicated on the display - After measuring, remove the measuring lines from the measured object and turn the DMM off. proceed as follows to measure "A-DC" direct current: - Turn the DMM on and select measuring function "A". The table shows the different measuring functions and possible measuring ranges. When a minus "-" appears in front of the measured value when measuring DC, the measured voltage is negative (or the measuring lines have been mixed up). - After measuring, remove the measuring lines from the measured object and turn the DMM off. Make sure that all the circuit parts, switches and components and other objects of measurement are disconnected from the voltage and discharged. - Plug the red measuring line into the measuring jack (8) and the black measuring line into the COM measuring jack (7) . - Check the measuring lines for continuity by connecting both measuring prods with one another. - If "OL" (overload) appears on the display , you have exceeded the measuring range or the measuring circuit has been broken. - After measuring, remove the measuring lines from the measured object and turn the DMM off. If you carry out a resistance measurement, make sure that the measuring points which you contact with the test prods are free from dirt, oil, solderable lacquer or the like. Make sure that all the circuit parts, switches and components and other objects of measurement are disconnected from the voltage and discharged. - Plug the red measuring line into the measuring jack (8) and the black measuring line into the COM measuring jack (7) . [. . . ] Place a new battery into the battery compartment (15), observing the correct polarity. Even batteries protected against leaking can corrode and thus release chemicals which may be detrimental to your health or destroy the battery compartment. Remove the batteries if the device is not used for longer periods of time to prevent leaking. Leaking or damaged batteries may cause alkali burns if they come in contact with the skin. [. . . ]
