I have consumption on 0,2 amps, but on consumed ampes its not showing anything. When higher consumption exampel 10 amps its shows, but not on small consumption like 0,2 amp. After 14 days it should have shown 67 amps(0,2x24hx14 days). Any settings wrong?
@fairline, are you not charging at all during the 14-day period you mention? The consumed Ah counter resets after a charge cycle, so if you have any charge source connected (shore power, solar charge controller, dc-dc charger, etc) that has applied a charge to the battery bank in that period of time, you won't see that consumption show up.
No charging that period. I charge up all batteries, switch of all consumers, only some electronict on engine that consume 0,2 amp pr hour..After 14 days consumed amps shows 0, should have been approx 67 amps..
Hmmm that is odd indeed. Shouldn't be a setting issue; generally if the shunt can see a draw, the head unit can track it.
Question, though: is the display showing -.2, or .2?
The difference being that .2 is showing a charge, -.2 is showing a draw. This would explain why the head unit isn't showing cumulative consumption, if it's not reading it as consumed.
If you're seeing .2 rather than -.2, the problem is that the negative supplying your engine electronics is connected to the wrong side of the shunt, or the shunt is connected in reverse. Is that possible? Can you post a photo of the shunt connections?
In the app is something called "current threshold". Mine is set to 0.1A and it counts everything over 0.1A. Witch value is in your bmv?
Mine is set to 0,1 amp also. Mayby put it to 0,0 amp? Is that the set value its start counting abow, i dont understand waht Current Threshold means
In the Manual it's described like this:
07. Current threshold When the current measured falls below this value it will be considered zero. The current threshold is used to cancel out very small currents that can negatively affect the long term state-of-charge readout in noisy environments. For example if the actual long term current is 0,0A and due to injected noise or small offsets the battery monitor measures -0,05A, and in the long term the BMV can incorrectly indicate that the battery needs recharging. When the current threshold in this example is set to 0,1A, the BMV calculates with 0,0A so that errors are eliminated. A value of 0,0A disables this function. Default Range Step size 0,1A 0 – 2A 0,01A
in short: Everything under the set value is considered as 0A. Try set it to 0.0A and it disables this function.
