Megger’s DET4TD2 1000-347 4 Terminal Ground Resistance Tester is designed for simple operation and outdoor use. The tester measures resistance from 0.01 Ω to 20k Ω and rejects noise up to 40V peak to peak. The dry-cell battery powered DET4TD2 1000-347 boasts a large selector switch allowing users to easily choose between 2, 3 or 4 pole tests – even with gloved hands. The vast, clear LCD and thumb-sized test button render the unit well suited for outdoor conditions.

 

The DET4TD2 1000-347 automatically confirms the connection and conditions of the P spike, C spike in addition to the level of ground noise, showing the status on the display. Even more, a voltmeter is included to enable measurement of ground voltage and the DET4TD2 1000-347 is rated to IP54 and CAT IV 100 V.
