DIGITAL MULTIMETER, , ADVANTAGE, , They are having high input impendence, So there is no loading effect, , ‘They are having higher accuracy., , An unambiguous reading is obtained., , The output can be interfaced with extemal equipment., , They are available in smaller sizes., , It can be used for measurement of A.C. and D.C. both quantity., , Itcan be used for measurement of various parameters such as resistance, voltage, current, ete., , Tthas sensitivity of 20 LOWY which is fairy high., , ‘Measurement of quantities with different range can be possible., , Itis small in size or compact., , Itis very simple touse unlike analog m as results are displayed in numeric value, directly and user need not have to read manually from the scale, , , , DISADVANTAGE, , ‘The LCD display depends on a battery or extemal power source. When the batteryis low,, the display will be dim, making it difficult to read., , There is a voltage | imitation. Ifit is increased beyond the limit, the meter will be, damaged., , Itismore expensive than the analog type., , It should be used as per manufacturer specified measurement range and as per category, rating, jing todo this will case damage to the equipment and also cause personal, injury.
