indicator, please use the company’s charging instrument to charge. It’s the smart charger for the battery charger. When the battery is full, that is, the charger indicator light to turn off automatically stop charging the battery, effectively preventing battery overcharge. Note: if the instrument will not be used in long-term, you also should be carried out regularly charge the battery (such as two months) ,in order to avoid battery over-discharge damage. -
Page 11: 2、Multi-Polar Parallel Grounding Resistance Measurement
instrument is equipped with two shut up: voltage clamp and current clamp. As shown in Figure 2, potential E in the voltage-clamp is excited in the measured and cause current I in the circuit. And the current in the clamp can be measured. Using Ohm's law: R = E / I, the value of R can be obtained. - Page 12 below. Figure 4 Then R Of which: : the measured value; : grounding resistance; : All other tower grounding resistance of the equivalent parallel resistance. Although from a strictly theoretical, because of the so-called "mutual resistance" existence, R is not the usual sense electrotechnics parallel value (it will larger than the value in electrotechnics), but because the grounding hemisphere is much less than their distance and number of the grounding points is big...

Page 13: 3、Two-Clamp Method Measure The Independent Grounding
Note: The clamps of charging and receiving are not interchangeable. 3 、 Two-clamp method measure the independent grounding objection A ． There must be an effective closed-loop for two-clamp method in the testing process The solution is to find an auxiliary electrode, and link the tested grounding objection with well grounding system (such as water pipes, etc.) Then clamp the two clamps on the wire with a distance of 30cm. -
