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.
