Dual Display Meter Digital Voltmeter Ammeter Panel 100V 10A

Detail Dual Display Meter Digital Voltmeter Ammeter Panel 100V 10A

LED DC 0-100V 10A Dual display Meter Digital Voltmeter Ammeters Panel Amp Volt
Gauge 0.28" Red Blue LED



Note: the range of 50A or 100A of the table regardless of whether the measured
current is less than 10A must be connected to the shunt to measure the current!
Otherwise it will burn the head.



The voltage display is normal and the current display is 0.00 or 0.0





Make sure that the thick black line is receiving the negative pole of the
battery and the thick red wire is connected to the negative pole of the load.
(Note that the discharge is not the same as the wiring of the charge, see the
final concept of load and power). (The use of original imported chip head, the
factory after a very rigorous testing and calibration to ensure that no quality
problems before leaving the factory. Encountered current display 0 99.99% of the
wiring is wrong, please patiently carefully check the wiring)



Current display is not allowed





If it is a direct power supply or independent power supply with the device power
is a common ground, as long as the black line can be broken off precision.



Connected to the power supply is not displayed





Any AC power through the rectifier must be connected to a 1000uF electrolytic
capacitor filter before the power supply to the meter.



Judge the header is good or bad (the following is the normal case of the two
cases)





Not connected to the shunt, then fine red line and thin black line to the power
supply, the range of 50A of the table current display 50.0 ~ 59.9, range of 100A
of the table shows 100 to 109;



Connected to the shunt, then fine red line and thin black line to the power
supply, the range of 50A meter current display 0.00, the range of 100A of the
table shows 0.0;
