(2) Can not be isolated power supply.6, Display mode:999mA: When the display value is less than 99mA, only two digits are displayed;when it is greater than 99mA, three digits are displayed10A: When the display value is less than 1A, only two digits are displayed;when it is greater than 1A, three digits are displayed20A/75mV, 50A/75mV, 100A/75mV: When the display value is less than 9.9A, only two digits will be displayed;when it is greater than 9.9A, only three digits will be displayed200A/75mV,300A/75mV, 500A/75mV, 1000A/75mV: When the display value is less than 99A, only two digits are displayed;when it is greater than 99A, only three digits are displayed. Technical Parameters: Supply voltage：1.Standard：DC4.5 ~ 30V（Note:The maximum input voltage can not exceed 30V, or be burnt.）2.isolation meter：DC8-18VOperating current：1.Standard： <20mA；2.isolation meter<200mATest current:DC100uA/1mA/10mA/100mA/1A/5A/10A/20A (Direct test) DC20A/30A/50A/100A/200A/300A/5000A/1000A (Must connect to external shunt)Display mode0.56 "LED with red/blue/green digitsMeasurement accuracy1% (± 2 digits)Measurement rate≥ 500mS / timeDimension *9*21 mMounting hole45.5*26.5mm Features: The difference bewteen the standard meter and the isolation meter:(1) Standard meter：The negative of power supply and the testing side are connected.It need a independent power supply.It can't be allowed more than two meters use one power supply.(2) isolation meter：The negative of power supply and the testing side are not connected.They are isolated.It can be allowed more than two meters use one power supply.The wide power supply range, with reverse polarity protection.DC20A,The decimal point automatically shifted.The testing side and the power supply side of the negative is connected(except the isolation meter).With a current calibration potentiometer, you can calibrate by yourself. The tolerance is absolutely exist.Good anti-interference ability, showing the refresh speed.With four wires,connection is convenient,used to monitor the battery current,can be also used for other products. Connection Method: Connection diagram for DC10A & Less than DC10A Connection diagram: only for DC20A direct test Connection diagram for DC20A & More than DC20A, must connect to an external shunt Working conditions: Operating temperature: -10 ~ +50 ℃ Working humidity: 10 ~ 80% (no condensation) Working pressure: 80 ~ 106kPa Sun exposure: no direct exposure Shipment: Worldwide shipping.
