User manual VOLTCRAFT VC-110

[. . . ] These operating instructions belong with this product. 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! [. . . ] Before changing the measurement range, always shut off the circuit. 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. Pressing this button again, takes you back etc. 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. - Turn the DMM on and select measuring range "". - 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. With resistances of >1 MOhm, this may take a few seconds. - 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. - Turn the DMM on and select measuring range . - 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. [. . . ] Make sure that the batteries are not short-circuited. You can order suitable alkaline batteries stating the following order no. Only use alkaline batteries, as they are powerful and have a long service life. Old electronic devices are recyclable and should not be disposed of in the household waste. [. . . ]
