Current Readings Innacurate

Hello,
We have purchased two of the Dual Display DC Panel meters with current shunt (Part #100417- See link below) from you through Amazon. Both are reading inaccurate current values. We have tried to adjust with the trim pot on the back of the meter and we have also tried two different shunts ( 50A/.75mV Both from Drok) but the closest we can achieve is -1.2A on one meter and -1.8A on the other. Do these meters always display the current draw as a negative value? I have tried to swap the wiring configuration but reading still shows negative values. Is there a procedure to Zero the Ammeter portion of this display other than the trim-pot?

Thank you,
-Preston
