It uses the four terminal measurement principle; test leads with duplex hand spikes are provided, although alternative types of test leads are available. The Megger D7001 will measure from 1 μohm to 59,99 ohms in five ranges, each of which is selected by a rotary switch. Simple controls make the ohmmeter easy to operate. The readings are given directly in ohms with the decimal point correctly positioned. The 3 3/4 -digit L.E.D. display has 12 mm (1/2 in.) high characters and is easy to read in poor lighting conditions. The ON/OFF/LOCK switch has two “on” positions: a LOCK position for continuous operation and a momentary spring-held ON position that helps conserve battery power when taking a series of readings on the high-current ranges. Variations in test current or battery condition will not result in loss of accuracy. A switch is used to reverse the connections to the potential terminals so that differences in reading caused by a suspected zero offset can be eliminated from a measurement. The condition of the digital display and the measuring circuit batteries is shown on a separate analogue panel meter. The Megger D7001 is completely selfcontained in a strong plastic case fitted with a detachable protective cover. The unit incorporates rechargeable battery cells and the charging circuit within the casing.
