Battery Monitor shows discharge current when "power kill switch is off." What is the power usage of the monitor itself?

Hi, I have a BMV-712. Installed it last week. Initially, everything seemed to be working great (i.e. when I plug into shore power shows +amps, power off shows no -amps, etc). Recently I began to notice a consistent -0.4 to -0.5 discharge that is consistent even when I have the "master" switch of camper off. Nothing is powered. Any idea what could be going wrong here? How much power does the BMV-712 use?

0.001 amp!

Have all loads turned off. Use Victron connect, and in the battery settings hit the "calibrate" button to zero the BMV.
