Product Details
MEGGER DET5/4 Dry cell 2, 3 and 4 Pole Earth Tester
Simple, fully automatic operation. Choice of three or four terminal measurement. Autoranging from 10 mO to 20 kO. Tests to BS7671, BS7430, BS6651 and VDE 0413. High tolerance to spike resistance helps testing in urban areas. Noise rejection to 40 V.
Operation is started by pushing one of two buttons on the front panel; one for three terminal measurement and one for four terminal testing. All other functions of the instrument are completely automatic. The instrument checks for conditions that may cause an invalid reading during a test. The low service error and wide operating temperature range enable accurate results to be achieved in real on-site conditions.
There are four ranges covering measurements from 10 mO to 20 kO. The earth resistance reading is displayed quickly, accurately and directly on a large, clear 31/2 digit liquid crystal display. The display indicates when there is a high test spike resistance and also when the noise interference is too high to take a valid reading. If the batteries need replacing or recharging this will also be shown on the display.
