Install shunt for DC current measurement:
IMPORTANT! The shunt must be installed in the negative line to avoid
damage. Positive voltage applied to terminals #9 and #10 will cause damage
to the meter.
Install the shunt at any point in the DC negative feed line.Short sense
wires minimize voltage loss and interference, and result in the most
accurate metering.
There must be no loads connected to the battery terminal or the shunt of
Battery 1 or the Amp-Hour Function will not operate correctly.
