4. Instruction and Maintain
1. Please cut off the connection between the electrical equipment
and power source. When the tested resistance is less than 1Ω,
please link the line to C2 and P2
2. Please test at least for 3 or 4 times and take the average
value.
3. Can’t connect the line as the normal way when test the
resistance HB-JD. The connection can see current and voltage meter.
4. If the test circuit is not available or over range and the meter
shows “1”.It means overflow. Please check whether the circuit is
well connected or over range.
5. The meter indicates “←” when the battery voltage is under 7.2V,
it means battery is in short supply. In order to solve the problem,
please connect the AC
Supplier or exchange the battery.(6 size 5 dry batteries)
6. Link to power line directly if using rechargeable battery.
Charging time is more than 8 hours.
7. When place the machine, please pay attention on the temperature
and humidity. It is better to place the machine in a dry and airy
place
