YB4835VA Isolation Voltmeter Ammeter DC 0-100V 300V 600V Ampere Volt Panel Meter DC Voltage Current Meter 10A 20A 50A 100A 500A
1，999mA, 2A, 5A, 10A, 20A,the shunt is built in.
2，More than 20A ,you must use a shunt to work,even 0.1A, or it will be burnt.
3，More than 20A,the shunt is not built in,you need to buy it separately.
(1)If you have a shunt , please note your shunt specification (standard is 75mV, if no notes, all according to 75mV delivery)
(2)If you don't have a shunt, please order the corresponding shunt, we will not notice at the time of shipment.
4，Because the 24V battery charge full of floating voltage may be more than 30V, so "no" recommended direct use 24V battery.
5，In the following circumstances, it is strongly recommended to choose: isolation meter(isolated power supply meter):
(1) When two or more meters are installed on a device. (2) Can not be isolated power supply.
1，Standard meter： <20mA；
2，Isolation meter:<200mA
Display mode: 0.39 "LED, Red for voltage，Green for current
Dimensions: 70 × 40 × 30 mm
Installation opening: 68 × 38 mm
Measurement rate: ≥ 500mS / time
Measurement accuracy: 1% (± 2 digits)
(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.
Display voltage and current on the screen at the same time.
Use the SMT technology,so consistency is very good.
With a back cover,safe ,reliable and dustproof.
The decimal point automatically shifted.
With a voltage calibration potentiometer, current calibration potentiometer, you can calibrate by yourself. The tolarance is absolutely exist.
Good anti-interference ability, showing the refresh speed.
With five wires,connection is convenient,used to monitor the battery voltage,can be also used for other products.
This meter is equipped with five wires, please find professionals in strict accordance with the following connection diagram, if any questions please feel free to contact customer service.
Meter power supply: two-wire terminals
Testing side:three-wire terminals
COM: Test common terminal（TheCOMis commond negative of voltmeter and ammeter）
V +: Test positive voltage input
A +: Test positive current input. It can only be connect the load negative and load power negative, as shown below.
Suitable for "20A or less",no need a shunt:
Suitable for "more than 20A ,must need a shunt:
