    Hello. Is there a way to calibrate VAC8010F meter? For me it displays 1 amp drain when I have charger connected to the battery after the battery is fully charged. For this reason it will always show 0 AH remaining despite the fact that the battery is new and fully charged.

    Hello Instrument user,

    Did you connect charger and battery as per charging diagram? If AH  is always zero, it should be discharging status.

    AH only increase when charging. At discharging status, it keep decreasing until reach 0.

    Best regards.

    I connected it correctly. It displays both charging and discharging but when I leave the charger connected the Ah goes to 0 when in fact the battery is full.

    Hello Instrument user,

    Do you mean connect charger and battery as per charging diagram? And did you program OAH?

    Would  you like to  show us how it is by video? In that way ,we can get more details and find solution quickly.

    You can share  a video link here or send attachment to service@droking.com

    Best regards.

    Hi, I connected it as diagram shows. In fact it is my second one, the first one did not have temperature sensor so I switched both the hall sensor, sender and the display to new one. I don’t recall the previous one having constant 1 amp draw so the error is in the device. When I connected I set the battery capacity and the remaining charge to 100% as the battery was full. The video would just show a -1 AMP draw from the battery when battery voltage is 13,8V which, according to lead-acid technology would not be possible with charger connected correctly to the load side.

    Hello

    To confirm the problem quickly, we hope to get more details by video. Would you like to show all of issue you have?

    And negative current doesn’t mean  it is discharging current.  May I know if the  current follws the arrow on current transformer?

    Best regards,

    Hi, yes the current follows the arrow. Here is a picture of the meter when battery is fully charged and charger is connected. There are 2 screws on the hall sensor, I was originally wondering if I could adjust them so it would display 0 in this case. I know some meters have the possibility to calibrate- like shown in minute 3 in this video https://www.youtube.com/watch?v=LSg6XbM6cS0 but my meter does not enter this menu.

    Hello,

    We  are sorry we can’t check problem from this picture. Actually, we hope to check how it works by video.

    Here are few questions:

    1. If the direction of  load current follows the arrow on current transformer, it should be positive current.  However it is negative current. Would you like to draw a simple diagram to show your connection?

    2.You mentioned AH goes to 0 when charger is connected. How it is before connecting charger, can it show AH?

    3.  Did you set the BPC parameter  successfully? If the right side is not the same as the left side, actually setting is not successfully.

     

    4. Did you try check current with other meter? Is it is 0 A?
