where probes were inserted.
2) The probe used for measuring grounding resistance
and soil resistivity is aluminum tube or round steel. Generally its
diameter is 25mm and its length is 0.5 ~ 1m.
3. Conductor resistance measurement (Fig. 3)
4. Ground voltage measurement
Wiring as Fig. 1, pull out the plug C1, insert the plug
between E, P1, and start the ground voltage gear (EV), the
indicator lights. The reading on LCD is AC ground voltage value
between E, P1.
5. Completed measurement, turnoff power supply, the
instrument shut down.
IV. Notes
1. When the instrument is stored you should pay attention to
environment temperature and moisture. It should be placed in
dry and ventilated environment and should be shielded from
humidity, acid, soda and corrosive gas damage.
