    Why do you not supply the specifications on these meter with the most needed spec. the current drain ie what current they pull. and also the impedance of the meter.

    OK the impedance is a bit high brow but would be of interest for some of the more interesting things people could use these things for. but the current consumption or wattage of the meter is really vital info.

    I am using this meter to monitor the battery in my trailer. I have it connected continuously at the moment. How long will it take to flatten the battery? as there is no spec I cannot tell. I do not have a working current meter to finds out myself.
    surly working current or wattage is normal in any piece of equipment.

    Is it OK to leave on the meter or will the meter cause the problem I am looking to avoid ie a flat battery. My battery is 11amp hour and it is used to power 2 2000lb pull winches. I need to know the condition of the battery as there is not a lot of spare capacity. thank you for any help

    I have just purchased meter WM-090559. this is the small, .36″ meter. Also want to know if there is significant draw from the meter as i also want to use it to continuously monitor battery level.

    AND, the meter does not register in the leftmost digit for voltages above 10V, and does not show the decimal point for voltages less than 10V. I would consider this defective.

    Hello david,
    Thank you for writing in.
    This meter is used to monitor the voltage, cannot be used to monitor the battery level.
    Could you please tell us more details of your operation, such as the input voltage,the wiring, the working environment?
    If you can, we sincerely hope that you can send us some images to let us check the problem details.
    You can send us the information by email (service at droking dot com).
    Waiting for your reply.
    Best regards

    I understand that i am reading battery voltage, not actual capacity. Still have the question regarding continuous monitoring using this meter. Will it draw down the battery? And what about the display? Shouldn’t all the LEDs work? I have not installed the meter, just testing it with various batteries at this point.
    Thank you

    Hello david,
    Thank you for your reply.
    This meter is powered by the measured battery.
    If the power of battery become less, the display of the meter will become dark.
    The power consumption of the meter is about 5-25MA.
    As your description, the LED cannot work may be caused by the problem of the chip.
    Could you please tell us your order ID so that we can find a solution for you?
    Waiting for your reply.
    Best regards
