7. Notes
Before using this tester, you should use high AC voltage detect and alarm function to
make sure there is no high AC voltage in the line, and use voltage test function to
make sure there is no high DC voltage in the line, after that, you can use other
functions, which not only protects user safety but also protects the tester from
damage.
◆
During the test, there will be the dangerous voltage in the line when you press the test
keys, please pay attention to the safe and do not touch the test clamp.
◆
If there is “V”, which is displayed in the LCD during the test, it means that there is high DC
V in the line, please take the clamp and pay attention to the safety.
◆
The distance where tester can detect the voltage is related to the high/low of the voltage
which is tested, the test environment and the weather; the voltage which is tested is higher,
the distance of electromagnetic eradiation is longer; the rain, snow and fog can absorb part of
electromagnetism, therefore, the test distance is small; if there is other bars such as the trees,
wall and so on, and they can absorb a part of electromagnetism and the distance is small.
◆
Please loose all the keys to avoid discharge of the battery when the instrument is not
used.
◆
Please check whether there is high AC V or DC V in the line or not before operate the
tester to avoid the damage to the instrument or person.
◆
Take the clamp immediately if there is high DC V in the line.
