Technical
Parameters

 Based
on the various questions that customers often have, the following summary
references are made:

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

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

Make
sure that the thick black wire is connected to 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 charging wiring, see the concept
of load and power afterwards .) (Meter using imported chips,
through a very rigorous testing and calibration to ensure the
factory . No quality issues before shipment. Meet current
display 0 cases of 99.99% is wired wrong, please be patient
carefully check the wiring)

Current
display is not allowed

If
it is directly powered or the independent power supply is co-located with the
equipment power supply, as long as the thin black line is disconnected, it can
be accurate.

Connected
to the power supply does not display

Any
AC power that has been rectified must be filtered by an electrolytic
capacitor of 1000uF or more to supply power to the meter.

Judging
whether the header is good or bad (the following are the two cases of the
normal header)

Without
the shunt, connect the thin red line and the thin black line to the power
supply, the meter current of the range
of 50A shows 50.0~59.9 , and the meter with the
range of 100Ashows 100~109 ;

Connect
the shunt, connect the thin red line and the thin black line to the power
supply, the meter current of the range
of 50A shows 0.00 , and the meter with the range
of 100A shows0.0 ;

Other
considerations

The
current can only be measured in the negative pole of the power supply and the
negative pole of the load.

Voltage
range: The power supply voltage range of the 5 lines
is4~28V , that is, the voltage of the thin red line cannot
exceed 28V .
