4. Warning
1. When measuring 32 V DC / 25 V AC be sure that no cables are connected to the current measuring socket and the main switch is not in
diode or resistor testing mode.Always make sure that you connected the cable to the right socket for its voltage.
2. Be cautious when measuring voltage higher than 50V, especially in the case of high current.
3. Do not connect the unit to "live" circuits.
4. When measuring current, turn off the voltage before you connect the multimeter. Do not try to measure current that is higher than 20A.
5. When testing the diode or the resistor, turn off the voltage before you start the test.
6. Always select the function and measuring range appropriate for the task. If you are unsure choose the largest range and do it backwards
till you find the right one.
7. Make sure that the instrument wire and the insulation is intact.
8. Be cautious, do not exceed the overload range found in this manual.
9. When switching a fuse replace it with ratings specified.
10. When switching the fuse or changing the battery turn off the multimeter and disconnect every circuit before opening the case of the
device
5. maintenance of the multiemter
1. Keep the multimeter dry, if it gets wet switch it off and dry it immediately. Liquids could corrode the circuits inside the unit.
2. Use the multimeter only in normal temperature, if the temperature gets too high it could shorten the lifetime of the device and can damage
batteries and melt plastic parts.
3. Be careful with the unit. If you drop it, it can damage the multimeter and the case which can cause malfunction.
4. Keep the device away from dust, it can significantly shorten the lifetime of the multimeter.
5. You can clean the unit with a clean wet towel, do not use any cleaning liquids or acids.
