    Hello, I just purchased a JS-C33 type of programmable battery monitor from Amazon.

    In reading the instructions, to Calibrate the monitor for use with 12volt Lead Acid battery, the user needs to obtain a 19v to 20v voltage source.

    No such source can be found in USA America, that I can find.

    Question:

    Why was 20 volts chosen as an appropriate calibration level?

    What can you suggest for Calibration work-around?

    Thanks

    Hello Dennis Burke,

    Only when there is  large error on voltage reading, you need to calibrate voltage reading.  Did you have problem on voltage reading?

    Any adjustable power supply can offer 20v voltage.

    Best regards.
