Using Introduction
1.Power supply
This machine is to use an external power supply, the instrument has
the right power jack, using a dedicated power line instrument with
(Annex 2) can be easily connected with the 12V storage battery; high
quality 12V/2A regulated power supply in the table can be used for
configuring instrument (Annex 7). When using other 220V/12V power
adapter, please pay attention to the current more than 1A, the
voltage shall not exceed 15V, power output plug and instrument
matching, polarity is negative.
Tips
Due to the use of an external power supply, it is connected with the
negative pole of the power supply with COM jack of the machine, can
be regarded as the ground output. Need to pay attention to the
following tips: 1, When using external adapter, the terminal should
be connected with the measured system of public ground;
2, When using 12V vehicle power supply, the terminal is connected
with the automobile bonding, can no longer leads. If you need to
ground output, you should avoid accidentally touch between the
terminal and the power supply (5V or 12V) positive power which can
cause short circuit fault.
