Precautions and maintenance of KF-6500 digital grounding resistance tester
1. When measuring the protective grounding resistance, it is necessary to disconnect the electrical equipment from the power supply connection point. When measuring grounding resistance less than 1 Ω, dedicated wires should be used to connect them to the grounding body, with C2 on the outside and P2 on the inside (as shown in Figure 4):
2. When storing and storing this table, attention should be paid to the ambient temperature and humidity. It is advisable to place it in a dry and ventilated place to avoid moisture, acid and alkali, and corrosive gases. It should not be exposed to rain, direct sunlight, or dropped
3. When measuring the grounding resistance of a large grounding grid, it is not possible to measure it according to the general wiring method. The buried insertion point can be selected according to the provisions of the ammeter and voltmeter measurement methods.
4. When measuring the grounding resistance, it is advisable to repeat the measurement 3-4 times in different directions and take the average value.
5. When the battery voltage is below 7.2V in this table, the header displays the undervoltage symbol "←", indicating that the battery voltage is insufficient. At this time, the power cord should be plugged in for charging, and the charging time should be greater than 4 hours (the machine has a built-in charger and a dedicated power cord, so users do not need to configure a charger separately)
6. Attachment
(1) Four dedicated test wires, one charging power cord, one instruction manual, and one certificate of conformity
⑵ Additional equipment available: 2 grounding probes, one 20m and one 40m wire each (price to be calculated separately).
