Earth/Ground Tester

Procedure of Measurements

To keep the instrument as simple as possible at the time of delivery, all special

functions, such as LIMIT input, BEEPER programming, measurement of

earthing impedance (R

) etc, are not activated at delivery. They can be acti-

vated with personalized user's code (see "Changing of all Pre-set Data with

Personalized Code"). Refer to Figure 8.
