    in reply to: Dork VAC9010H All Calibration Settings Including menu/save digits. #83623

    Hello John Watkins,

    Do you mean an easy way to calibrate current or reset AH? There are no other ways to calibrate current and voltage.

    If you want to reset AH, please move the yellow cursor to “LOP”, once the yellow cursor  is invsible,just short press button OK , then the time will be cleared, the AH value will be zeroed or filled.

    After powering off, WH will be cleared automatically.

    Best regards.

    in reply to: YB26C USB Tester Manual and Issues #83620

    Hello David S,

    oK, it should be ASIN number B09C4D1VXD.

    Here are two notice:

    1. Without PD device connected to output port, display is not on. You can hold the button”I” 5 second to trigger PD 5V voltage for other devices withou PD protocol.

    2. When input voltage is over 5.8v, no output voltage on USB-A output, but USB-C still work.

    For your second testing, we want to check if  the power source to USB-C input  is with PD protocol? If not, it is normal the unit powers on when you  plug a cable into USB-C output (no device on the other end).

    Best regards.

    Hello Cooper,

    That is calibration setting. Please don’t change any parameters, just disconnect power supply and power on again.

    Notice: Please don’t hold the button when power on.

    Best regards,

    in reply to: Wire gauge for Meter #83016

    Hello,

    If you mean the wire connected to green terminal, it only measure voltage, load current will not go there. You can  use any wires gauge, juse make sure the withstand voltage value of lead wire is enough.

    Best regards.

    in reply to: buck converter #82819

    Hello,

    We can’t confirm which buck converter it is,  but for all of converters, they can only set a limit for current so that actual output is not over that level.

    Actual output current mainly depends on your load. If load just draw 1A, converter can’t let it draw 2A.

    Best regards,

    in reply to: installing 200123 AC power meter #82818

    Hello,

    It doesn’t need to identify  direction.  And this is connected AC circuit, there is no polarity.

    There are three kinds of power. Active Power,Reactive power and inspecting power.

    Our meter only monitor active power.

    The calculating formula for active power is P=U*I*cosφ( cosφ represents power factor). As different load have different power factor, the current and active power is also different.

    In general, Power=UI, because the  power factor of pure resistive load is closed to 1

    The power factor of inductive and capacitive loads is between 0-1.

    So when you test the pure resistive load, Power is equal to or near U*I; but when you test the inductive and capacitive loads (e.g.television,computer), Power< U*I.

    You can check the power factor   for your load.

    Best regards,

    DROK

    in reply to: Stuck at calibration screen #82537

    Hello,

    Unless  there is large error on voltage reading, it is not necessary to calibrate reading each time.

    In generla, you just need to hold the button to exit  calibration setup. If it can’t work, please disconnect power supply and power on again.

    Best regards.

    in reply to: DC-DC boost converter to raise voltage from 28-30V to at least 82 V providing 3A #82250

    Hello CHRIS，

    From 12v to 120v, there is huge voltage difference. It will cause more power dissipation and the actual output may not be as excepted. Please consider if you can accept that.
